NATURE & SCOPE OF MANAGERIAL ECONOMICS
The terms Managerial Economics and Business Economics are often
used interchangeably. However, the terms Managerial Economics
has become more popular and seems to displace Business
Economics.
DECISION-MAKING AND FORWARD PLANNING
The chief function of a management executive in a business firm is
decision-making and forward planning. Decision-making refers to
the process of selecting one action from two or more alternative
courses of action. Forward planning on the other hand is arranging
plans for the future. In the functioning of a firm the question of
choice arises because the available resources such as capital, land,
labour and management, are limited and can be employed in
alternative uses. The decision-making function thus involves making
choices or decisions that will provide the most efficient means of
attaining an organisational objectives, for example profit
maximization. Once a decision is made about the particular goal to
be achieved, plans for the future regarding production, pricing,
capital, raw materials and labour are prepared. Forward planning
thus goes hand in hand with decision-making. The conditions in
which firms work and take decisions, is characterised with
uncertainty. And this uncertainty not only makes the function of
decision-making and forward planning complicated but also adds a
different dimension to it. If the knowledge of the future were
perfect, plans could be formulated without error and hence without
any need for subsequent revision. In the real world, however, the
business manager rarely has complete information about the future
sales, costs, profits, capital conditions. etc. Hence, decisions are
made and plans are formulated on the basis of past data, current
information and the estimates about future that are predicted as
accurately as possible. While the plans are implemented over time,
more facts come into the knowledge of the businessman. In
accordance with these facts the plans may have to be revised, and
a different course of action needs to be adopted. Managers are thus
engaged n a continuous process of decision-making through an
uncertain future and the overall problem that they deal with is
adjusting to uncertainty.
To execute the function of ‘decision-making in an uncertain
frame-work’, economic theory can be applied with considerable
advantage. Economic theory deals with a number of concepts and
principles relating to profit, demand, cost, pricing, production,
competition, business cycles and national income, which are aided
by allied disciplines like accounting. Statistics and Mathematics also
can be used to solve or at least throw some light upon the problems
of business management. The way economic analysis can be used
towards solving business problems constitutes the subject matter of
Managerial Economics.
DEFINITION
According to McNair the Merriam, Managerial Economics consists of
the use of economic modes of thought to analyse business
situations.
Spencer and Siegelman have defined Managerial Economics
as “the integration of economic theory with business practice for the
purpose of facilitating decision-making and forward planning by
management.”
The above definitions suggest that Managerial economics is
the discipline, which deals with the application of economic theory
to business management. Managerial Economics thus lies on the
margin between economics and business management and serves
as the bridge between the two disciplines. The following Figure 1.1
shows the relationship between economics, business management
and managerial economics.
APPLICATION OF ECONOMICS TO BUSINESS MANAGEMENT
The application of economics to business management or the
integration of economic theory with business practice, as Spencer
and Siegelman have put it, has the following aspects :
Reconciling traditional theoretical concepts of
economics in relation to the actual business behavior
and conditions: In economic theory, the technique of
analysis is that of model building. This involves making some
assumptions and, drawing conclusions on the basis of the
assumptions about the behavior of the firms. The
assumptions, however, make the theory of the firm unrealistic
since it fails to provide a satisfactory explanation of what the
firms actually do. Hence, there is need to reconcile the
theoretical principles based on simplified assumptions with
actual business practice and develop appropriate extensions
and reformulation of economic theory. For example, it is
usually assumed that firms aim at maximising profits. Based
on this, the theory of the firm suggests how much the firm
will produce and at what price it would sell. In practice,
however, firms do not always aim at maximum profits (as they
may think of diversifying or introducing new product etc.) To
that extent, the theory of the firm fails to provide a
satisfactory explanation of the firm’s actual behavior.
Moreover, in actual business language, certain terms like
profits and costs have accounting concepts as distinguished
from economic concepts. In managerial economics, an
attempt is made to merge the accounting concepts with the
economics, an attempt is made to merge the accounting
concepts with the economic concepts. This helps in a more
effective use of financial data related to profits and costs to
suit the needs of decision-making and forward planning.
Estimating economic relationships: This involves the
measurement of various types of elasticities of demand such
as price elasticity, income elasticity, cross-elasticity,
promotional elasticity and cost-output relationships. The
estimates of these economic relationships are to be used for
the purpose of forecasting.
Predicting relevant economic quantities: Economic
quantities such as profit, demand, production, costs, pricing
and capital are predicated in numerical terms together with
their probabilities. As the business manager has to work in an
environment of uncertainty, the future needs to be foreseen
so that in the light of the predicted estimates, decision-making
and forward planning may be possible.
Using economic quantities in decision-making and
forward planning: This involves formulating business
policies for establishing future business plans. This nature of
economic forecasting indicates the degree of probability of
various possible outcomes, i.e., losses or gains that will occur
as a result of following each one of the available strategies.
Thus, a quantified picture gets set up, that indicates the
number of courses open, their possible outcomes and the
quantified probability of each outcome. Keeping this picture in
view, the business manager is able to decide about which
strategy should be chosen.
Understanding significant external forces: Applying
economic theory to business management also involves
understanding the important external forces that constitute
the business environment and with which a business must
adjust. Business cycles, fluctuations in national income and
government policies pertaining to taxation, foreign trade,
labour relations, antimonopoly measures, industrial licensing
and price controls are typical examples. The business
manager has to appraise the relevance and impact of these
external forces in relation to the particular business unit and
its business policies.
CHARACTERISTICS OF MANAGERIAL ECONOMICS
There are certain chief characteristics of managerial economics,
which can help to understand the nature of the subject matter and
help in a clear understanding of the following terms:
Managerial economics is micro-economic in character. This is
because the unit of study is a firm and its problems.
Managerial economics does not deal with the entire economy
as a unit of study.
Managerial economics largely uses that body of economic
concepts and principles, which is known as Theory of the Firm
or Economics of the Firm. In addition, it also seeks to apply
profit theory, which forms part of distribution theories in
economics.
Managerial economics is concrete and realistic. I avoids
difficult abstract issues of economic theory. But it also
involves complications ignored in economic theory in order to
face the overall situation in which decisions are made.
Economic theory ignores the variety of backgrounds and
training found in individual firms. Conversely, managerial
economics is concerned more with the particular environment
that influences decision-making.
Managerial economics belongs to normative economics rather
than positive economics. Normative economy is the branch of
economics in which judgments about the desirability of
various policies are made. Positive economics describes how
the economy behaves and predicts how it might change. In
other words, managerial economics is prescriptive rather than
descriptive. It remains confined to descriptive hypothesis.
Managerial economics also simplifies the relations among
different variables without judging what is desirable or
undesirable. For instance, the law of demand states that as
price increases, demand goes down or vice-versa but this
statement does not imply if the result is desirable or not.
Managerial economics, however, is concerned with what
decisions ought to be made and hence involves value
judgments. This further has two aspects: first, it tells what
aims and objectives a firm should pursue; and secondly, how
best to achieve these aims in particular situations. Managerial
economics, therefore, has been described as normative
microeconomics of the firm.
Macroeconomics is also useful to managerial economics since
it provides an intelligent understanding of the business
environment. This understanding enables a business
executive to adjust with the external forces that are beyond
the management’s control but which play a crucial role in the
well being of the firm. The important forces are: business
cycles, national income accounting, and economic policies of
the government like those relating to taxation foreign trade,
anti-monopoly measures and labour relations.
DIFFFFERENCE BETWEEN MANAGERIAL ECONOMICS AND
ECONOMICS
The difference between managerial economics and economics can
be understood with the help of the following points:
Managerial economics involves application of economic
principles to the problems of a business firm whereas;
economics deals with the study of these principles only.
Economics ignores the application of economic principles to
the problems of a business firm.
Managerial economics is micro-economic in character,
however, Economics is both macro-economic and micro-
economic.
Managerial economics, though micro in character, deals only
with a firm and has nothing to do with an individual’s
economic problems. But microeconomics as a branch of
economics deals with both economics of the individual as well
as economics of a firm.
Under microeconomics, the distribution theories, viz., wages,
interest and profit, are also dealt with. Managerial economics
on the contrary is mainly concerned with profit theory and
does not consider other distribution theories. Thus, the scope
of economics is wider than that of managerial economics.
Economic theory assumes economic relationships and builds
economic models. Managerial economics adopts, modifies and
reformulates the economic models to suit the specific
conditions and serves the specific problem solving process.
Thus, economics gives the simplified model, whereas
managerial economics modifies and enlarges it.
Economics involves the study of certain assumptions like in
the law of proportion where it is assumed that “The variable
input as applied, unit by unit is homogeneous or identical in
amount and quality”. Managerial economics on the other
hand, introduces certain feedbacks. These feedbacks are in
the form of objectives of the firm, multi-product nature of
manufacture, behavioral constraints, environmental aspects,
legal constraints, constraints on resource availability, etc.
Thus managerial economics, attempts to solve the
complexities in real life, which are assumed in economics. this
is done with the help of mathematics, statistics, econometrics,
accounting, operations research, etc.
OTHER TERMS FOR MANAGERIAL ECONOMICS
Certain other expressions like economic analysis for business
decisions and economics of business management have also been
used instead of managerial economics but they are not so popular.
Sometimes expressions like ‘Economics of the Enterprise’, ‘Theory
of the Firm’ or ‘Economics of the Firm’ have also been used for
managerial economics. It is, however, not appropriate t use theses
terms because managerial economics, though primarily related to
the economics of the firm, differs from it in the following respects:
First, ‘Economics of the Firm’ deals with the theory of the firm,
which is a body of economic principles relating to the firm
alone. Managerial economics on the other hand deals with
the, application of the same principles to business.
Secondly, the term ‘Economics of the firm’ is too simple in its
assumptions whereas managerial economics has to reckon
with actual business behaviour, which is much more complex.
SCOPE OF MANAGERIAL ECONOMICS
As regards the scope of managerial economics, there is no general
uniform pattern. However, the following aspects may be said to be
inclusive under managerial economics:
Demand analysis and forecasting.
Cost and production analysis.
Pricing decisions, policies and practices.
Profit management.
Capital management.
These aspects may also be defined as the ‘Subject-Matter of
Managerial Economics’. In recent years, there is a trend towards
integrations of managerial economics and operations research.
Hence, techniques such as linear programming, inventory models
and theory of games have also been regarded as a part of
managerial economics.
Demand Analysis and Forecasting
A business firm is an economic Organisation, which transforms
productive resources into goods that are to be sold in a market. A
major part of managerial decision-making depends on accurate
estimates of demand. This is because before production schedules
can be prepared and resources are employed, a forecast of future
sales is essential. This forecast can also guide the management in
maintaining or strengthening the market position and enlarging
profits. The demand analysis helps to identify the various factors
influencing demand for a firm’s product and thus provides
guidelines to manipulate demand. Demand analysis and forecasting,
thus, is essential for business planning and occupies a strategic
place in managerial economics. It comprises of discovering the
forces determining sales and their measurement. The chief topics
covered in this are:
Demand determinants
Demand distinctions
Demand forecasting.
Cost and Production Analysis
A study of economic costs, combined with the data drawn from the
firm’s accounting records, can yield significant cost estimates.
These estimates are useful for management decisions. The factors
causing variations in costs must be recognised and thereby should
be used for taking management decisions. This facilitates the
management to arrive at cost estimates, which are significant for
planning purposes. An element of cost uncertainty exists in this
because all the factors determining costs are not always known or
controllable. Therefore, it is essential to discover economic costs
and measure them for effective profit planning, cost control and
sound pricing practices. Production analysis is narrower in scope
than cost analysis. The chief topics covered under cost and
production analysis are:
Cost concepts and classifications
Cost-output relationships
Economics of scale
Production functions
Cost control.
Pricing Decisions, Policies and Practices
Pricing is a very important area of managerial economics. In fact
price is the origin of the revenue of a firm. As such the success of a
usiness firm largely depends on the accuracy of price decisions of
that firm. The important aspects dealt under area, are as follows:
Price determination in various market forms
Pricing methods
Differential pricing product-line pricing and price forecasting.
Profit Management
Business firms are generally organised with the purpose of making
profits. In the long run, profits provide the chief measure of success.
In this connection, an important point worth considering is the
element of uncertainty existing about profits. This uncertainty
occurs because of variations in costs and revenues. These are
caused by factors such as internal and external. If knowledge about
the future were perfect, profit analysis would have been a very easy
task. However, in a world of uncertainty, expectations are not
always realised. Thus profit planning and measurement make up the
difficult area of managerial economics. The important aspects
covered under this area are:
Nature and measurement of profit.
Profit policies and techniques of profit planning.
Capital Management
Among the various types and classes of business problems, the
most complex and troublesome for the business manager are those
relating to the firm’s capital investments. Capital management
implies planning and control and capital expenditure. In this
procedure, relatively large sums are involved and the problems are
so complex that their disposal not only requires considerable time
and labour but also top-level decisions. The main elements dealt
with cost management are:
Cost of capital
Rate of return and selection of projects.
The various aspects outlined above represent the major
uncertainties, which a business firm has to consider viz., demand
uncertainty, cost uncertainty, price uncertainty, profit uncertainty
and capital uncertainty. We can, therefore, conclude that
managerial economics is mainly concerned with applying economic
principles and concepts to adjust with the various uncertainties
faced by a business firm.
MANAGERIAL ECONOMICS AND OTHER SUBJECTS
Yet another useful method of explaining the nature and scope of
managerial economics is to examine its relationship with other
subjects. The following discussion helps to understand relationship
between managerial economics and economics, statistics,
mathematics, accounting and operations research.
Managerial Economics and Economics
Managerial economics is defined as a subdivision of economics that
deals with decision-making. It may be viewed as a special branch of
economics bridging the gulf between pure economic theory and
managerial practice. Economics has two main divisions-
microeconomics and Macroeconomics. Microeconomics has been
defined as that branch where the unit of study is an individual or a
firm. It is also called “price theory” (or Marshallian economics) and
is the main source of concepts and analytical tools for managerial
economics. To illustrate, various micro-economic concepts such as
elasticity of demand, marginal cost, the short and the long runs,
various market forms, etc., are all of great significance to
managerial economics.
Macroeconomics, on the other hand, is aggregative in
character and has the entire economy as a unit of study. The chief
contribution of macroeconomics to managerial economics is in the
area of forecasting. The modern theory of income and employment
has direct implications for forecasting general business conditions.
As the prospects of an individual firm often depend greatly on
general business conditions, individual firm forecasts rely on general
business forecasts.
A survey in the U.K. has shown that business economists have
found the following economic concepts quite useful and of frequent
application:
Price elasticity of demand
Income elasticity of demand
Opportunity cost
Multiplier
Propensity to consume
Marginal revenue product
Speculative motive
Production function
Liquidity preference
Business economists have also found the following main areas
of economics as useful in their work. Demand theory
Theory of firms – price, output and investment decisions
Business financing
Public finance and fiscal policy
Money and banking
National income and social accounting
Theory of international trade
Economies of developing countries.
Thus, it is obvious that Managerial Economics is very closely
related to Economics.
Managerial Economics and Statistics
Statistics is important to managerial economics in several ways.
Managerial economics calls for the organising quantitative data and
deriving a useful measure of appropriate functional relationships
involved in decision-making. For instance, in order to base its pricing
decisions on demand and cost considerations, a firm should have
statistically derived or calculated demand and cost functions.
Managerial economics also employs statistical methods for
experimental testing of economic generalisations. The
generalisations can be accepted in practice only when they are
checked against the data from the world of reality and are found
valid. Managers do not have exact information about the variables
affecting decisions and have to deal with the uncertainty of future
events. The theory of probability, upon which statistics is based,
provides logic for dealing with such uncertainties.
Managerial Economics and Mathematics
Mathematics is yet another important subject closely related to
managerial economics. This is because managerial economics is
mathematical in character, as it involves estimating various
economic relationships, predicting relevant economic quantities and
using them in decision-making and forward planning. Knowledge of
geometry, trigonometry ad algebra is not only essential but also
certain mathematical tools and concepts such as logarithms and
exponential, vectors, determinants, matrix, algebra, calculus,
differential as well as integral, are the most commonly used devices.
Further, operations research, which is closely related to managerial
economics, is mathematical in character. It provides and analyses
data ad develops models, benefiting from the experiences of
experts drawn from different disciplines, viz., psychology, sociology,
statistics and engineering.
MANAGERIAL ECONOMICS AND ACCOUNTING
Managerial economics is also closely related to accounting, which is
concerned with recording the financial operations of a business firm.
In fact, a managerial economist depends chiefly on the accounting
information as an important source of data required for his decision-
making purpose. for instance, the profit and loss statement of a firm
shows how well the firm has done and whether the information it
contains can be used by managerial economist to throw significant
light on the future course of action that is whether the firm should
improve its productivity or close down. Therefore, accounting data
require careful interpretation, reconstruction and adjustments
before they can be used safely and effectively. It is in this context
that the link between management accounting and managerial
economics deserves special mention. The main task of management
accounting is to provide the sort of data, which managers need if
they are to apply the ideas of managerial economics to solve
business problems correctly. The accounting data should be
provided in such a form that they fit easily into the concepts and
analysis of managerial economics.
Managerial Economics and Operations Research
Operations research is a subject field that emerged during the
Second World War and the years thereafter. A good deal of
interdisciplinary research was done in the USA. as well as other
western countries to solve the complex operational problems of
planning and resource allocation in defence and basic industries.
Several experts like mathematicians, statisticians, engineers and
others teamed up together and developed models and analytical
tools leading to the emergence of this specialised subject. Much of
the development of techniques and concepts, such as linear
programming, inventory models, game theory, etc., emerged from
the working of the operation researchers. Several problems of
managerial economics are solved by the operation research
techniques. These highlight the significant relationship between
managerial economics and operations research. The problems
solved by operation research are as follows:
Allocation problems: An allocation problem confronts with
the issue that men, machines and other resources are scarce,
related to the number sand size of the jobs that need to be
completed. The examples are production programming and
transportation problems.
Competitive problems: competitive problems deal with
situations where managerial decision-making is to be made in
the face of competitive action. That is, one of the factors to be
considered is: “What will competitors do if certain steps are
taken?” Price reduction, for example, will not lead to increased
market share if rivals follow suit.
Waiting line problems : Waiting line problems arise when a
firm wants to know how many machines it should install in
order to ensure that the amount of ‘work-in-progress’ waiting
to be machined is neither too small nor too large. Such
situations arise when for example, a post office, or a bank
wants to know how many cash desks or counter clerks it
should employ in order to balance the business lost through
long guesses against the cost of installing more equipment or
hiring more labour.
Inventory problems: Inventory problems deal with the
principal question: “What is the optimum level of stocks of
raw-materials, components or finished goods for the firm to
hold?”
The above discussion explains that the managerial economics is
closely related to certain subjects such as economics, statistics,
mathematics and accounting. A trained managerial economist
combines concepts and methods from all these subjects by bringing
them together to solve business problems. In particular, operations
research and management accounting are getting very close to
managerial economics.
USES OF MANAGERIAL ECONOMICS
Managerial economics achieves several objectives. The principal
objectives are as follows:
It presents those aspects of traditional economics, which are
relevant for business decision-making in real life. For this
purpose, it picks from economic theory those concepts,
principles and techniques of analysis, which are concerned
with the decision-making process. These are adapted or
modified in such a way that it enables the manager to take
better decisions. Thus, managerial economics attains the
objective of building a suitable tool kit from traditional
economics.
Managerial economics also incorporates useful ideas from
other disciplines such as psychology, sociology, etc. If they are
found relevant for decision-making. In fact, managerial
economics takes the aid of other academic disciplines that are
concerned with the business decisions of a manager in view of
the various explicit and implicit constraints subject to which
resource allocation is to be optimised.
It helps in reaching a variety of business decisions even in a
complicated environment. Certain examples of such decisions
are those decisions concerned with:
o The products and services to be produced
o The inputs and production techniques to be used
o The quantity of output to be produced and the selling
prices to be subscribed
o The best sizes and locations of new plants
o Time of replacing the equipment
o Allocation of the available capital
Managerial economics helps a manager to become a more
competent model builder. Thus, he can pick out the essential
relationships, which characterise a situation and leave out the
other unwanted details and minor relationships.
At the level of the firm, functional specialists or functional
departments exist, e.g., finance, marketing, personnel,
production etc. For these various functional areas, managerial
economics serves as an integrating agent by co-ordinating the
different areas. It then applies the decisions of each
department or specialist, those implications, which are
pertaining to other functional areas. Thus managerial
economics enables business decision-making to operate not
with an inflexible and rigid but with an integrated perspective.
This integration is important because the functional
departments or specialists often enjoy considerable autonomy
and achieve conflicting goals.Managerial economics keeps in
mind the interaction between the firm and society and
accomplishes the key role of business as an agent in attaining
social economic welfare. There is a growing awareness that
besides its obligations to shareholders, business enterprise
has certain social obligations as well. Managerial economics
focuses on these social obligations while taking business
decisions. By doing so, it serves as an instrument of furthering
the economic welfare of the society through socially oriented
business decisions.
Thus, it is evident that the applicability and usefulness of
managerial economics is obtained by performing the following
activates:
Borrowing and adopting the tool-kit from economic theory.
Incorporating relevant ideas from other disciplines to achieve
better business decisions.
Serving as a catalytic agent in the course of decision-making
by different functional departments/specialists at the firm’s
level.
Accomplishing a social purpose by adjusting business
decisions to social obligations.
ECONOMIC THEORY AND MANAGERIAL ECONOMICS
Economic theory offers a variety of concepts and analytical tools
that can assist the manager in the decision-making practices.
Problem solving in business has, however, found that there exists a
wide disparity between the economic theory of a firm and actual
observed practice, thus necessitating the use of many skills and be
quite useful to examine two aspects in this regard:
The basic tools of managerial economics which it has
borrowed from economics, and
The nature and extent of gap between the economic theory of
the firm and the managerial theory of the firm.
Basic Economic Tools in Managerial Economics
The most significant contribution of economics to managerial
economics lies in certain principles, which are basic to the entire
range of managerial economics. The basic principles may be
identified as follows:
1. Opportunity Cost Principle
The opportunity cost of a decision means the sacrifice of
alternatives required by that decision. This can be best understood
with the help of a few illustrations, which are as follows:
The opportunity cost of the funds employed in one’s own
business is equal to the interest that could be earned on those
funds if they were employed in other ventures.
The opportunity cost of the time as an entrepreneur devotes
to his own business is equal to the salary he could earn by
seeking employment.
The opportunity cost of using a machine to produce one
product is equal to the earnings forgone which would have
been possible from other products.
The opportunity cost of using a machine that is useless for any
other purpose is zero since its use requires no sacrifice of
other opportunities.
If a machine can produce either X or Y, the opportunity cost of
producing a given quantity of X is equal to the quantity of Y,
which it would have produced. If that machine can produce 10
units of X or 20 units of Y, the opportunity cost of 1 X is equal
to 2 Y.
If no information is provided about quantities produced,
except about their prices then the opportunity cost can be
computed in terms of the ratio of their respective prices, say
Px/Py.
The opportunity cost of holding Rs. 500 as cash in hand for
one year is equal to the 10% rate of interest, which would
have been earned had the money been kept as fixed deposit
in a bank. Thus, it is clear that opportunity costs require the
ascertaining of sacrifices. If a decision involves no sacrifice, its
opportunity cost is nil.
For decision-making, opportunity costs are the only relevant
costs. The opportunity cost principle may be stated as under:
“The cost involved in any decision consists of the sacrifices of
alternatives required by that decision. If there are no sacrifices,
there is no cost.”
Thus in macro sense, the opportunity cost of more guns in an
economy is less butter. That is the expenditure to national fund for
buying armour has cost the nation of losing an opportunity of buying
more butter. Similarly, a continued diversion of funds towards
defence spending, amounts to a heavy tax on alternative spending
required for growth and development.
2. Incremental Principle
The incremental concept is closely related to the marginal costs and
marginal revenues of economic theory. Incremental concept
involves two important activities which are as follows:
Estimating the impact of decision alternatives on costs and
revenues.
Emphasising the changes in total cost and total cost and total
revenue resulting from changes in prices, products,
procedures, investments or whatever may be at stake in the
decision.
The two basic components of incremental reasoning are as
follows:
Incremental cost: Incremental cost may be defined as the
change in total cost resulting from a particular decision.
Incremental revenue: Incremental revenue means the change
in total revenue resulting from a particular decision.
The incremental principle may be stated as under:
A decision is obviously a profitable one if:
o It increases revenue more than costs
o It decreases some costs to a greater extent than it
increases other costs
o It increases some revenues more than it decreases
other revenues
o It reduces costs more that revenues.
Some businessmen hold the view that to make an overall
profit, they must make a profit on every job. Consequently, they
refuse orders that do not cover full cost (labour, materials and
overhead) plus a provision for profit. Incremental reasoning
indicates that this rule may be inconsistent with profit maximisation
in the short run. A refusal to accept business below full cost may
mean rejection of a possibility of adding more to revenue than cost.
The relevant cost is not the full cost but rather the incremental cost.
A simple problem will illustrate this point.
IIIustration
Suppose a new order is estimated to bring in additional revenue of
Rs. 5,000. The costs are estimated as under:
Labour Rs. 1,500
Material Rs. 2,000
Overhead (Allocated at 120% of labour cost) Rs. 1,800
Selling administrative expenses
(Allocated at 20% of labour and material
cost)
Rs. 700
Total Cost Rs. 6,000
The order at first appears to be unprofitable. However,
suppose, if there is idle capacity, which can be, utilised to execute
this order then the order can be accepted. If the order adds only Rs.
500 of overhead (that is, the added use of heat, power and light, the
added wear and tear on machinery, the added costs of supervision,
and so on), Rs. 1,000 by way of labour cost because some of the idle
workers already on the payroll will be deployed without added pay
and no extra selling and administrative cost then the incremental
cost of accepting the order will be as follows.
Labour Rs. 1,500
Material Rs. 2,000
Overhead Rs. 500
Total Incremental Cost Rs. 3,500
While it appeared in the first instance that the order will result
in a loss of Rs. 1,000, it now appears that it will lead to an addition
of Rs. 1,500 (Rs. 5,000- Rs. 3,500) to profit. Incremental reasoning
does not mean that the firm should accept all orders at prices,
which cover merely their incremental costs. The acceptance of the
Rs. 5,000 order depends upon the existence of idle capacity and
labour that would go unutilised in the absence of more profitable
opportunities. Earley’s study of “excellently managed” large firms
suggests that progressive corporations do make formal use of
incremental analysis. It is, however, impossible to generalise on the
use of incremental principle, since the observed behaviour is
variable.
3. Principle of Time Perspective
The economic concepts of the long run and the short run have
become part of everyday language. Managerial economists are also
concerned with the short-run and long-run effects of decisions on
revenues as well as on costs. The actual problem in decision-making
is to maintain the right balance between the long-run and short-run
considerations. A decision may be made on the basis of short-run
considerations, but may in the course of time offer long-run
repercussions, which make it more or less profitable than it
appeared at first. An illustration will make this point clear.
IIIustration
Suppose there is a firm with temporary idle capacity. An order for
5,000 units comes to management’s attention. The customer is
willing to pay Rs. 4.00 per unit or Rs. 20,000 for the whole lot but
not more. The short-run incremental cost (ignoring the fixed cost) is
only Rs. 3.00. Therefore, the contribution to overhead and profit is
Re. 1.00 per unit (Rs. 5,000 for the lot. However, the long-run
repercussions of the order ought to be taken into account are as
follows:
If the management commits itself with too much of business
at lower prices or with a small contribution, it may not have
sufficient capacity to take up business with higher
contributions when the opportunity arises. The management
may be compelled to consider the question of expansion of
capacity and in such cases; even the so-called fixed costs
may become variable.
If any particular set of customers come to know about this
low price, they may demand a similar low price. Such
customers may complain of being treated unfairly and feel
discriminated. In response, they may opt to patronise
manufacturers with more decent views on pricing. The
reduction or prices under conditions of excess capacity may
adversely affect the image of the company in the minds of its
clientele, which will in turn affect its sales.
It is, therefore, important to give due consideration to the time
perspective. The principle of time perspective may be stated as
under: ‘A decision should take into account both the short-run and
long-run effects on revenues and costs and maintain the right
balance between the long-run and short-run perspectives.”
Haynes, Mote and Paul have cited the case of a printing
company. This company pursued the policy of never quoting prices
below full cost though it often experienced idle capacity and the
management was fully aware that the incremental cost was far
below full cost. This was because the management realised that the
long-run repercussions of pricing below full cost would make up for
any short-run gain. The management felt that the reduction in rates
for some customers might have an undesirable effect on customer
goodwill particularly among regular customers not benefiting from
price reductions. It wanted to avoid crating such an “image” of the
firm that it exploited the market when demand was favorable but
which was willing to negotiate prices downward when demand was
unfavorable.
4. Discounting Principle
One of the fundamental ideas in economics is that a rupee
tomorrow is worth less than a rupee today. This seems similar to the
saying that a bird in hand is worth two in the bush. A simple
example would make this point clear. Suppose a person is offered a
choice to make between a gift of Rs. 100 today or Rs. 100 next year.
Naturally he will choose the Rs. 100 today.
This is true for two reasons. First, the future is uncertain and
there may be uncertainty in getting Rs. 100 if the present
opportunity is not availed of. Secondly, even if he is sure to receive
the gift in future, today’s Rs. 100 can be invested so as to earn
interest, say, at 8 percent so that. one year after the Rs. 100 of
today will become Rs. 108 whereas if he does not accept Rs. 100
today, he will get Rs. 100 only in the next year. Naturally, he would
prefer the first alternative because he is likely to gain by Rs. 8 in
future. Another way of saying the same thing is that the value of Rs.
100 after one year is not equal to the value of Rs. 100 of today but
less than that. To find out how much money today is equal to Rs.
100 would earn if one decides to invest the money. Suppose the
rate of interest is 8 percent. Then we shall have to discount Rs. 100
at 8 per cent in order to ascertain how much money today will
become Rs. 100 one year after. The formula is:
V =
Rs. 100
1 + i
where,
V = present value
i = rate of interest.
Now, applying the formula, we get
V =
Rs. 100
1 + i
=
100
1.08
If we multiply Rs. 92.59 by 1.08, we shall get the amount of
money, which will accumulate at 8 per cent after one year.
92.59 x 1.08 = 99.0072
= 1.00
The same reasoning applies to longer periods. A sum of Rs.
100 two years from now is worth:
V =
Rs. 100
=
Rs. 100
=
Rs. 100
(1+i)2 (1.08)2 1.1664
Similarly, we can also check by computing how much the
cumulative interest will be after two years. The principle involved in
the above discussion is called the discounting principle and is stated
as follows: “If a decision affects costs and revenues at future dates,
it is necessary to discount those costs and revenues to present
values before a valid comparison of alternatives is possible.”
5. Equi-marginal Principle
This principle deals with the allocation of the available resource
among the alternative activities. According to this principle, an input
should be allocated in such a way that the value added by the last
unit is the same in all cases. This generalisation is called the equi-
marginal principle.
Suppose a firm has 100 units of labour at its disposal. The firm
is engaged in four activities, which need labour services, viz., A, B, C
and D. It can enhance any one of these activities by adding more
labour but sacrificing in return the cost of other activities. If the
value of the marginal product is higher in one activity than another,
then it should be assumed that an optimum allocation has not been
attained. Hence it would, be profitable to shift labour from low
marginal value activity to high marginal value activity, thus
increasing the total value of all products taken together. For
example, if the values of certain two activities are as follows:
Value of Marginal Product of labour
Activity A = Rs. 20
Activity B = Rs. 30
In this case it will be profitable to shift labour from A to
activity B thereby expanding activity B and reducing activity A. The
optimum will be reach when the value of the marginal product is
equal in all the four activities or, when in symbolic terms:
VMPLA = VMPLB = VMPLC = VMPLD
Where the subscripts indicate labour in respective activities.
Certain aspects of the equi-marginal principle need
clarifications, which are as follows:
First, the values of marginal products are net of incremental
costs. In activity B, we may add one unit of labour with an
increase in physical output of 100 units. Each unit is worth 50
paise so that the 100 units will sell for Rs. 50. But the
increased output consumes raw materials, fuel and other
inputs so that variable costs in activity B (not counting the
labour cost) are higher. Let us say that the incremental costs
are Rs. 30 leaving a net addition of Rs. 20. The value of the
marginal product relevant for our purpose is thus Rs. 20.
Secondly, if the revenues resulting from the addition of labour
are to occur in future, these revenues should be discounted
before comparisons in the alternative activities are possible.
Activity A may produce revenue immediately but activities B,
C and D may take 2, 3 and 5 years respectively. Here the
discounting of these revenues will make them equivalent.
Thirdly, the measurement of value of the marginal product
may have to be corrected if the expansion of an activity
requires an alternative reduction in the prices of the output. If
activity B represents the production of radios and it is not
possible to sell more radios without a reduction in price, it is
necessary to make adjustment for the fall in price.
Fourthly, the equi-marginal principle may break under
sociological pressures. For instance, du to inertia, activities
are continued simply because they exist. Similarly, due to
their empire building ambitions, managers may keep on
expanding activities to fulfil their desire for power.
Department, which are already over-budgeted often, use
some of their excess resources to build up propaganda
machines (public relations offices) to win additional support.
Governmental agencies are more prone to bureaucratic self-
perpetuation and inertia.
Gaps between Theory of the Firm and managerial Economics
The theory of the firm is a body of theory, which contains certain
assumptions, theorems and conclusions. These theorems deal with
the way in which businessmen make decisions about pricing, and
production under prescribed market conditions. It is concerned with
the study of the optimisation process.
For optimality to exist profit must be maximised and this can
occur only when marginal cost equals marginal revenue. Thus, the
optimum position of the firm is that which maximises net revenue.
Managerial economics, on the other hand, aims at developing a
managerial theory of the firm and for the purpose it takes the help
of economic theory of the firm. However, there are certain
difficulties in using economic theory as an aid to the study of
decision-making at the level of the firm. This is because for the
purposes of business decision-making it fails to provide sufficient
analytical tools that are useful to managers. Some of the reasons
are as follows:
Underlying all economic theory is the assumption that the
decision-maker is omniscient and rational or simply that he is
an economic man. Thus being omniscient means that he
knows the alternatives that are available to him as well as the
outcome of any action he chooses. The model of “economic
man” however as an omniscient person who is confronted
with a compete set of known or probabilistic outcomes is a
distorted representation of reality. The typical business
decision-maker usually has limited information at his disposal,
limited computing ability and a limited number of feasible
alternatives involving varying degrees of risk. Further, the net
revenue function, which he is expected to maximise, and the
marginal cost and marginal revenue functions, which he is
expected to equate, require excessive knowledge of
information, which is not known and cannot be obtained even
by the most careful analysis. Hence, it is absurd to expect a
manager to maximise and equalise certain critical functional
relationships, which he does not know and cannot find out.
In micro-economic theory, the most profitable output is where
marginal cost (MC) and marginal revenue (MR) are equal. In
Figure 1.2, the most profitable output will be at ON where
MR=MC. This is the point at which the slope of the profit
function or marginal profit is zero. This is highlighted in Figure
1.3 where the most profitable output will be again at ON. In
economic theory, the decision-maker has to identify this
unique output level, which maximises profit.
In real world, however, a complexity often arises, viz., certain
resource limitations exist. As a result, it is not possible to attain the
maximum output level (ON). In practical terms the maximum output
possible as a result of resource limitations is, say, OM. Now the
problem before the decision-maker is to find out whether the
output, which maximises profit, is OM or some other level of output
to the left of OM. It is obvious that economic theory is of no help for
ON level of output because it is not relevant in view of the resource
limitations. A managerial economist here has to take the aid of
linear programming, which enables the manager to optimise or
search for the best values within the limits set by inequality
conditions.
Another central assumption in the economic theory of the
firm is that the entrepreneur strives to maximise his
residual share, or profit. Several criticisms of this
assumption have been made:
o The theory is ambiguous, as it doesn’t clarify.
Whether it is short or long run profit that is to be
maximised. For example, in the short run, profits
could be maximised by firing all research and
development personnel and thereby eliminating
considerable immediate expenses. This decision
would, however, have a substantial impact on long-
run profitability.
o Certain questions create some confusion around the
concept of profit maximisation. Should the firm seek
to maximise the amount of profit or the rate of profit?
What is the rate of profit? Is it profit in relation to
total capital or profit in relation to shareholders’
equity?
o There is no allowance for the existence of “psychic
income” (Income other than monetary, power,
prestige, or fame), which the entrepreneur might
obtain from the firm, quite apart from his monetary
income.
o The theory does not recognise that under modern
conditions, owners and managers are separate and
distinct groups of people and the latter may not be
motivated to maximise profits.
o Under imperfect competition, maximisation is an
ambiguous goal, because actions that are optimal for
one will depend on the actions of the other firms.
o The entrepreneur may not care to receive maximum
profits but may simply want to earn “satisfactory
profits”. This last point is particularly relevant from
the behavioural science standpoint because it
introduces a concept of satiation. The notion of
satiation plays no role in classical economic theory.
To explain business behaviour in terms of this theory,
it is necessary to assume that the firm’s goals are not
concerned with maximising profit, but with attaining
a certain level or rate of profit, holding a certain
share of the market or a certain level of sales. Firms
would try to satisfy rather than maximise. But
according to Simon the satisfying model damages all
the conclusions that can be derived concerning
resource allocation under perfect competition. It
focuses on the fact that the classical theory of the
firm is empirically incorrect as a description of the
decision-making process. Based on this notion of
satiation, it appears that one of the main strengths of
classical economic theory has been seriously
weakened.
Most corporate undertakings involve the investment of
funds, which are expect to produce revenues over a
number of years. The profit maximisation criterion provides
no basis for comparing alternatives that can promise
varying flows of revenue and expenditure over time.
The practical application of profit maximisation concept
also has another limitation. It provides no explicit way of
considering the risk associated with alternative decisions.
Two projects generating similar expected revenues in the
future and requiring similar outlays might differ vastly as
regarding the degree of uncertainty with which the benefits
to be generated. The greater the uncertainty associated
with the benefits, the greater the risk associated with the
project.
Baumol on the other hand is of the view that firms do not
devote all their energies to maximising profit. Rather a
company will seek to maximise its sales revenue as long as
a satisfactory level of profit is maintained. Thus Baumol has
substituted “Total sales revenue” for profits. Also, two
decision criteria or objectives have been advanced viz., a
satisfactory level of profit and the highest sales possible. In
other words, the firm is no longer viewed as working
towards one objective alone. Instead, it is portrayed as
aiming at balancing two competing and non-consistent
goals. Baumol’s model is based on the view that managers’
salaries, their status and other rewards often appear as
closely related to the companies’ size in which they work
and is measured by sales revenue rather than their
profitability. As such, managers may be more concerned to
increased size than profits. And the firm’s objective thus
becomes sales maximisation rather than profits
maximisation.
Empirical studies of pricing behaviour also give results that
differ from those of the economic theory of firm as can be
seen from the following examples:
o Several studies of the pricing practices of business
firms have indicated that managers tend to set
prices by applying some sort of a standard mark-up
on costs. They do not attempt to estimate marginal
costs, marginal revenues or demand elasticities,
even if these could be accurately measured.
o For many firms, prices are more often set to attain,
a particular target return on investment, say, 10 per
cent, than to maximise short or long-run profits.
o There is some evidence that firms experiencing
declining market shares in their industry strive
more vigorously to increase their sales than do
competing firms, which are experiencing steady or
increasing market shares.
An alternative model to profit maximisation is the concept
of
wealth maximisation, which assumes that firms seek to
maximise the present value of expected net revenues over
all periods within the forecasted future.
As pointed out by Haynes and Henry, a study of the
behaviour of actual firms shows that their decisions are not
completely determined by the market. These firms have
some freedom to develop decisions, strategies or rules,
which become part of the decision-making system within
the firm. This gap in economic theory has led to what has
come to be known as ‘Behavioural Theory of the Firm’. This
theory, however, does not replace the former but rather
powerfully supplements it. The behavioural theory
represents the firm as an adoptive institution. It learns
from experience and has a memory. Organisational
behaviour, is embodies into decision rules and standard
operating procedures. These may be altered over long run
as the firm reacts to “feedback” from experience. However,
in the short run, decisions of the organisation are
dominated by its rules of thumb and standard methods.
CONCLUSION
The various gaps between the economic theory of the firm and the
actual decision-making process at the firm level are many in
number. They do, however, stress that economic theory seriously
needs major fixing up and substantial changes are in progress for
creating better and different models. Thus the classical economic
concepts like those of rational man is undergoing important
changes; the notion of satisfying is pushing aside the aim of
maximisation and newer lines and patterns of thoughts are being
developed for finding improved applications to managerial decision-
making. A strong emphasis is laid on quantitative model building,
experimentation and empirical investigation and newer techniques
and concepts, such as linear programming, game theory, statistical
decision-making, etc., are being applied to revolutionise the
approaches to problem solving in business and economics.
MANAGERIAL ECONOMIST: ROLE AND RESPONSIBILITIES
A managerial economist can play a very important role by assisting
the management in using the increasingly specialised skills and
sophisticated techniques, required to solve the difficult problems of
successful decision-making and forward planning. In business
concerns, the importance of the managerial economist is therefore
recognised a lot today. In advanced countries like the USA, large
companies employ one or more economists. In our country too, big
industrial houses have understood the need for managerial
economists. Such business firms like the Tatas, DCM and Hindustan
Lever employ economists. A managerial economist can contribute to
decision-making in business in specific terms. In this connection,
two important questions need be considered:
1. What role does he play in business, that is, what particular
management problems lend themselves to solution through
economic analysis?
2. How can the managerial economist best serve management,
that is, what are the responsibilities of a successful
managerial economist?
Role of a Managerial Economist
One of the principal objectives of any management in its decision-
making process is to determine the key factors, which will influence
the business over the period ahead. In general, these factors can be
divided into two categories:
External
Internal
The external factors lie outside the control of management
because they are external to the firm and are said to constitute
business environment. The internal factors lie within the scope and
operations of a firm and hence within the control of management,
and they are known as business operations. To illustrate, a business
firm is free to take decisions about what to invest, where to invest,
how much labour to employ and what to pay for it, how to price its
products, and so on. But all these decisions are taken within the
framework of a particular business environment, and the firm’s
degree of freedom depends on such factors as the government’s
economic policy, the actions of its competitors and the like.
Environmental Studies of a Business Firm
An analysis and forecast of external factors constituting general
business conditions, for example, prices, national income and
output, volume of trade, etc., are of great significance since they
affect every business firm. Certain important relevant factors to be
considered in this connection are as follows:
The outlook for the national economy, the most important
local, regional or worldwide economic trends, the nature of
phase of the business cycle that lies immediately ahead.
Population shifts and the resultant ups and downs in regional
purchasing power.
The demand prospects in new as well as established markets.
Impact of changes in social behaviour and fashions, i.e.,
whether they will tend to expand or limit the sales of a
company’s products, or possibly make the products obsolete?
The areas in which the market and customer opportunities are
likely to expand or contract most rapidly.
Whether overseas markets expand or contract and the affect
of new foreign government legislations on the operation of the
overseas plants?
Whether the availability and cost of credit tend to increase or
decrease buying, and whether money or credit conditions
ahead are likely to easy or tight?
The prices of raw materials and finished products.
Whether the competition will increase or decrease.
The main components of the five-year plan, the areas where
outlays have been increased and the segments, which have
suffered a cut in their outlays.
The outlook to government’s economic policies and
regulations and changes in defence expenditure, tax rates
tariffs and import restrictions.
Whether the Reserve Bank’s decisions will stimulate or
depress industrial production and consumer spending and how
will these decisions affect the company’s cost, credit, sales
and profits.
Reasonably accurate data regarding these factors can enable the
management to chalk out the scope and direction of their own
business plans effectively. It will also help them to determine the
timing of their specific actions. And it is these factors, which present
some of the areas where a managerial economist can make
effective contribution. The managerial economist has not only to
study the economic trends at the micro-level but also must interpret
their relevance to the particular industry or firm where he works. He
has to digest the ever-growing economic literature and advise top
management by means of short, business-like practical notes. In
mixed economy like that of India, the managerial economist
pragmatically interprets the intentions of controls and evaluates
their impact. He acts as a bridge between the government and the
industry, translating the government’s intentions and transmitting
the reactions of the industry. In fact, the government policies
emerge out of the performance of industry, the expectations of the
people and political expediency.
Business Operations
A managerial economist can also be helpful to the management in
making decisions relating to the internal operations of a firm in
respect of such problems as price, rate of operations, investment,
expansion or contraction. Certain relevant questions in this
context would be as follows:
What will be a reasonable sales and profit budget for the
next year?
What will be the most appropriate production schedules
and inventory policies for the next six months?
What changes in wage and price policies should be made
now?
How much cash will be available next month and how
should it be invested?
Specific Functions
The managerial economists can play a further role, which can cover
the following specific functions as revealed by a survey pertaining to
Brittain conducted by K.J.W. Alexander and Alexander G. Kemp:
Sales forecasting.
Industrial market research.
Economic analysis of competing companies.
Pricing problems of industry.
Capital projects.
Production programmes.
Security / Investment analysis and forecasts.
Advice on trade and public relations.
Advice on primary commodities.
Advice on foreign exchange.
Economic analysis of agriculture.
Analysis of underdeveloped economics.
Environmental forecasting.
The managerial economist has to gather economic data, analyse
all relevant information about the business environment and
prepare position papers on issues facing the firm and the industry.
In the case of industries prone to rapid theological advances, the
manager may have to make continuous assessment of tl1e impact
of changing technology. The manager' may need to evaluate the
capital budget in the light of short and long-range financial, profit
and market potentialities. Very often, he also needs to prepare
speeches for the corporate executives. It is thus clear that in
practice, managerial economists perform many and various
functions. However, of all these, the marketing functions, i.e., sales
force listing an industrial market research, are the most important.
For this purpose, the managers may collect statistical records of
the sales performance of their own business and those rehiring to
their rivals, carry out analysis of these records and report on trends
in demand, their market shares, and the relative efficiency of their
retail outlets. Thus, while carrying out heir functions, the managers
may have to undertake detailed statistical analysis. There are, of
course, differences in the relative importance of· the various
functions performed from firm to firm and in the degree of
sophistication of the methods used in performing these functions.
But there is no doubt that the job of a managerial economist
requires alertness and the ability to work uriderpressure.
Economic Intelligence
Besides these functions involving sophisticated analysis, managerial
economist may also provide general intelligence service. Thus the
economist may supply the management with economic information
of general interest such as competitors
prices and products, tax rates, tariff rates, etc.
Participating in Public Debates
Many well-known business economists participate in public debates.
The government and society alike are seeking their advice and
views. Their practical experience in business and industry adds
prestige to their views. Their public recognition enhances their
protégé in the .firm itself.
Indian Context
In the Indian context, a managerial economist is expected to
perform the following functions:
Macro-forecasting for
demand and supply.
Production planning at macro and micro levels.
Capacity planning and product-mix determination.
Economics of various production lines.
Economic feasibility of new production lines / processes and
projects.
Assistance in preparation of overall development plans.
Preparation of periodical economic reports bearing on various
matters such as the company's product-lines, future growth
opportunities, market pricing situation, general business,. and
various national/international factors affecting industry and
business.
Preparing briefs; speeches, articles and papers for top
management for various chambers, Committees, Seminars,
Conferences, etc
Keeping management informed of various national and
International Developments on economic/industrial matters.
With the adoption of the new economic policy, the macro-
economic environment is changing fast and these changes have
tremendous implications for business. The managerial economists
have to playa much more significant role. They ha'1e to constantly
measure the possibilities of translating the rapidly changing
economic scenario into workable business opportunities. As India
marches towards globalisation, the managerial economists will have
to interpret the global economic events and find out how the firm
can avail itself of the various export opportunities or of establishing
plants abroad either wholly owned or in association with local
partners.
Responsibilities of a Managerial Economist
Besides considering the opportunities that lie before a managerial
economist it is necessary to take into account the services that are
expected by the management. For this, it is necessary for a
managerial economist to thoroughly recognise the responsibilities
and obligations. A managerial economist can serve the mana-
gement best by recognising that the main objective of the
business, is to make a profit on its invested capital. Academic
training and the critical comments from people outside the
business may lead a managerial economist to adopt an apologetic
or defensive attitude towards profits. There should be a strong
personal conviction on part of the managerial economist that
profits are essential and it is necessary to help enhance the ability
of the firm to make profits. Otherwise it is difficult to succeed in
serving management.
Most management decisions necessarily concern the future,
which is rather uncertain. It is, therefore, absolutely essential that a
managerial economist recognises his responsibility to make
successful forecast. By making the best possible forecasts and
through constant efforts to improve, a managerial' ng, the risks
involved in uncertainties. This enables the management to· follow a
more orderly course of business planning. At times, it is required
for the managerial economist to reassure the management that an
important trend will continue. In other cases, it is necessary to
point out the probabilities of a turning point in some activity of
importance to management. In any case, managerial economist
must be willing to make fairly positive statements about impending
economic developments. These can be based upon the best
possible information and analysis. The management's confidence in
a managerial economist increases more quickly and thoroughly
with
a record of successful forecasts, well documented in advance
and modestly evaluated when the actual results become
available.
A few consequences to the above proposition need also be
emphasised here.
First, a managerial economist has a major responsibility to alert
managelI1ent at the earliest possible moment in' case there is
an err6r' in his forecast. This will assist the mallagement in
making appropriate adjustment in policies and programmes
and strengthen his oWn position as a member of the
management team by keeplrighis fingers on the economic
pulse of the
business.
Secondly, a managerial economist must establish and maintain
many contacts with individuals and data sources: which would
not be immediately available to the other members of the
management. Extensive familiarity with reference sources and
material is essential. It is still more important that the known
individuals who are specialists in particular fields have a
bearing on tpe managerial economist's work. For this purpose,
it is required that managerial economist joins professional
associations and tak~ active part in them. In fact, one of the
best means of determining the quality of a managerial
economist is to evaluate his ability to obtain information
quickly by personal contacts rather than by lengthy research
from either readily available or obscure reference sources.
Within any business, there' may be a wealth of knowledge and
experience but the managerial economist would be really
useful ifit is possible pn his part to supplement the existing
know-how with additional information and in the quickest
possible manner.
Again, if a managerial economist is to be really helpful to the
management in successful decision-making and forward planning, it
is necessary'" to able to earn full status on the business team.
Readiness to take up special assignments, be that in study teams,
committees or special projects is another important requirement.
This is because it is necessary for the managerial economist to win
continuing support for himself and his professional ideas. Clarity of
expression and attempting to minimise the use of technical
terminology while communJcating his ideas to management
executives is also an essential role so as to win approval.
To conclude, a managerial economist has a very important role
to play by helping management in successful decision-making and
forward planning. But to discharge his role successfully, it is
necessary to recognise the 'relevant responsibilities and obligations.
To some business executives, however, a managerial economist is
still a luxury or perhaps even a necessary evil. It is not surprising,
therefore, to find that while tneir status is improving and their
impor;ance is gradually rising, managerial economists in certain
firms still 'feel quite insecure. Nevertheless, there is a definite and
growing realisation that they can contribute significantly to the
profitable growth of firms and effective solution oftMir problems,
and this' promises them a positive future.

LESSON – 2
DEMAND ANALYSIS
Demand is one of the crucial requirements for the existence of
any business firm. Firms are interested in their profit and sales,
both of which depend partially upon the demand for the product.
The decisions, which management makes with respect to
production, advertising, cost allocation, pricing, inventory
holdings, etc. call for an analysis of demand. While how much a
firm can produce depends upon its capacity and demand for its
products. If there is no demand for a product, its production is
unworthy. If demand falls short of production, one way to
balance the two is to create new demand through more and
better advertisements. The more the future demand for a
product, the more inventories the firm would hold. The larger
the demand for a firm's product, the higher is the price it can
charge.
Demand analysis seeks to identify and measure the forces
that determine sales. Once this is done the alternative ways of
manipulating or managing demand can easily be inferred.
Although, demand for a finri's product reflects what the
consumers buy, this can be influenced through manipulating the
factors on which consumers base their demands. Demand
analysis attempts to estiinate the demand for a product in
future, which further helps to plan production based on the
estimated demand.
MEANING OF DEMAND
Demand for a good implies the desire of an individual to acquire
the product. It also includes willingness and ability of ail individual
to pay for the product. For example, a miser's desire for and his
ability to pay for a car is not demand, for he does not have the
necessary will to pay for the car. Similarly, a poor person's desire
for· and his willingness to pay for a car is not demand because he
lacks the necessary purchasing power. One can also imagine an
individual, who possesses both the will and the purchasing power
to pay for a good. But this purchasing power is not the demand for
that good, this is because he does not have the desire to buy that
product. Therefore, demand is successful when there are all the
three factors: desire, willingness and ability. It should also be
noted that demand for any goods or services has no meaning
unless it is stated with reference to time, price, competing
product, consumer's incomes, tastes and preferences. This is
because demand varies with fluctuations in these factors. For
example, the demand for an Ambassador car in India is 40,000 is
meaningless unless it is stated that this was the demand ·in 1976
when an Ambassador car's price was around thirty thousand
rupees. The price of the competing cars’ prices were around the
same, a Bajaj scooter's price was around five thousand rupees and
petrol price was around three and a half rupees per litre. In 1977,
the demand for Ambassador cars could be different if any of the
above factors happened to be different. Furthermore, it should be
noted that a product is defined with reference to its particular
quality. If its quality changes it can be deemed as another
product. Thus, the demand for any product is the desire,
wi1lihigness and ability to buy the product with reference to a
partkular time and given values of variables on which it depends.
TYPES OF DEMAND
The demand for various kinds of goods is generally classified on
the basis of kinds of consumers, suppliers of goods, nature of
goods, duration of consumption goods, interdependence of
demand, period of demand and nature of use of goods
(intermediate or final), The major classifications of demand are as
follows:
Individual and market demand
Demand for firm's prodtictand industry's products
Autonomous and derived demand
Demand for durable and non-durable goods
Short-term and long-term demand
Individual and Market Demand
The quantity of a product, which an individual is willing to buy at
a particular price during a specific time period, given his money
income, his taste, and prices of other commodities (particularly
substitutes and complements), is called 'individual's demand for a
product'. The total quantity, which all comsumers are willing to
buy at a given price per time unit, given their money income,
taste, and prices of other commodities is known as 'market
demand for the good'. In other words, the market demand for a
good is the sum of the individual demands of all the c6-nsumers
of a product, over a time period at given prices.
Demand for Firm's Product and Industry's Products
The quantity of a firm's yield, that can be disposed of at a given
price over a period refers to the demand for firm's product. The
aggregate demand for the product of all firms of an industry is
known as the market-demand or demand for industry's product.
This distinction between the two kinds of demand is not of much
use in a highly competitive market since it merely signifies the
distinction between a sum and its parts. However, where market
structure is oligopolistic, a distinction between the demand for
firm's product and industry's product is useful from managerial
point of view. The product of each firm is so differentiated from the
products of the rival firms that consumers treat each product
different from the other. This gives firms an opportunity to plan the
price of a product, advertise it in order to capture a larger market
share thereby to enhance profits. For instance, market of cars,
radios, TV sets, refrigerators, scooters, toilet soaps and toothpaste,
all belong to this category of markets.
In case of monopoly and perfect competition, the distinction
between demand for a firm's product and industry's product is not
of much use from managerial point of view. In case of monopoly,
industry is one-firmindustiy andthe demand for firm's product is
the same as that of the industry. In case of perfect competition,
products of all firms .of the industry are homogeneous and price
for each firm is determined by industry. Firms have little
opportunity to plan the prices permissible under local conditions
and advertisement by a firm becomes effective for the whole
industry. Therefore, conceptual distinction between demand for
film's product and industry's product is not much use in business
decisions making.
Autonomous and Derived Demand
An Autonomous demand for a product is one that arises
independently of the demand for any other good whereas a derived
demand is one, which is derived from demand of some other good.
To look more closely at the distinction between the two kinds of
demand, consider the demand for commodities, which arise directly
from the biological or physical needs of the human beings, such as
demand for food, clothes and shelter. The demand for these goods
is autonomous demand. Autotnomous demand also arises as a'
result of demonstration effect, rise in income, and increase in
population and advertisement of new produCts. On the other hand,
the demand for a good that arises because of the demand for some
other good is called derived demand. For instance, demand for
land, fertiliser and agricultural tools and implements are derived
demand, since the demand of goods, depends on the demand of
food. Similarly, demand for steel, bricks, cement etc., is a derived
demand because it is derived from the demand for houses and
other kind of buildings. [n general, the demand for, producer goods
or industrial inputs is a derived one. Besides, demand for
complementary goods (which complement the use of other goods)
or for supplementary goods (which supplement or provide
additional utility from the use of other goods) is a derived demand.
For instance petrol is a complementary goods for automobiles and
a chair is a complement to a table. Consider some examples of
supplement goods. Butter is supplement to bread, mattress is
supplement to cot and sugar is supplement to tea. Therefore,
demand for petrol, chair, and sugar would be considered as derived
demand. The conceptual distinction between autonomous demand
and derived demand would be useful according to the point of view
of a bllsinessman to the extent the former can serve as an indicator
of the latter.
Demand for Durable and Non-durable Goods
Demand is often classified under demand for durable and non-
durable goods. Durable goods are those goods whose total utility is
not exhausted in single or short-run use. Such goods can be used
continuously over a period of time. Durable goods may be consumer
goods as well as producer goods. Durable consumer goods include
clothes, shoes, house furniture, refrigerators, scooters, and cars.
The durable producer goods include mainly the items under fixed
assets, such as building, plant and machinery, office furniture and
fixture. The durable goods, both consumer and producer goods, may
be further classified as semi-durable goods such as, clothes and
furniture and durable goods such as residential and factory
buildings and cars. On the other harid, non-durable goods are those
goods, which can be used only once such as food items and their
total utility is exhausted in a single use. This category of goods can
also be grouped under non-durable consumer and producer goods.
All food items such as drinks, soap, cooking fuel, gas, kerosene, coal
and cosmetics fall in the former category whereas, goods such as
raw materials', fuel and power, finishing materials and packing
items come in the latter category.
The demand for non-durable goods depends largely on their
current prices, consumers' income and fashion whereas the
expected price, income and change in technology influence the
demand for the durable good. The demand for durable goods
changes over a relatively longer period. There is another point of
distinction between demands for durable and non-durable goods.
Durable goods create demand for replacement or substitution of the
goods whereas non-durable goods do not. Also the demand for non-
durable goods increases or decreases with a fixed or constant rate
whereas the demand for durable goods increases or decreases
exponentially, i.e., it may depend· upon some factors such as
obsolescence of machinery, etg. For example, let us suppose that
the annual demand for cigarettes in a city is 10 million packets and
it increases at the rate of half-a-million packets per annum on
account of increase in population when other factors remain
constant. Thus, the total demand for cigarettes in the next year will
be 10.5 million packets and 11 million packets in the next to next
year and so on. This is a linear increase in the demand for a non-
durable good like cigarette. Now consider the demand for a durable
good, e.g., automobiles. Let us suppose: (i1 the existing number of
automobiles in a city, in a year is 10,000, (ii) the annual
replacement demand equals 10 per cent of the total demand, and
(iii) the annual autonomous increase ·in demand is 1000
automobiles. As such, the total annual clemand for automobiles in
four subsequent years is calculated and presented in Table 2.1.
Table 2.1: Annual Demand for Automobiles
Beginning Total no. of Replacement Annual Total Annualof the year automobiles demand autonomous demand increas
(Stock) demand in, demand
1st year 10,000 - - 10,000

4th year 14,200 1420 1000 16,620 2420
Stock + Replacement + Autonomous demand = TotalDemand
It may be seen from the Table 2.1 that the total demand for
automobiles is increasing at an increasing rate due to
acceleration in the replacement demand. Another factor, which
might accelerate the demand for automobiles and such durable
goods, is the rate of obsolescence of this category of goods.
Short-term and Long-term Demand
Short-term demand refers to the demand for goods that are
demanoed over a short period. In this category fall mostly the
fashion consumer goods, goods of seasonal use and inferior
substitutes during the scarcity period of superior goods. For
instance, the demand for fashion wears is short-term demand
though the demand for the generic goods such as trousers, shoes
and ties continues to remain a longterm demand. Similarly, demand
for umbrella, raincoats, gumboots, cold drinks and ice creams is of
seasonal nature; 'The demand for such goods lasts till the season
lasts. Some goods of this category are demanded for a very short
period, i.e., 1-2 week, for example, new greeting cards, candles and
crackers on occasion of diwali.
Although some goods are used only seasonally but are durable in
pature, e.g., electric fans, woollen garments, etc. The demand for
such goods is of also durable in nature but it is subject to seasonal
fluctuations. Sometimes, demand for certain gools suddenly
increases because of scarcity of their superior substitutes. For
examp1e, when supply of cooking gas suddenly decreases, demand
for kerosene, cooking coal and charcoal increases. In such cases,
additional demand is of shGrtterm nature. The long-term demand,
on the hand, refers to the demand, which exists over a long-period.
The change in long-term demand is visible only after a long period.
Most generic goods have long-term demand. For example, demand
for consumer and producer goods, durable and non-durable goods,
is long-term demand, though their different varieties or brands may
have only short-term demand. Short-term demand depends, by and
large, on the price of commodities, price of their substitutes, current
disposable income of the consumer, their ability to adjust their
consumption pattern and their susceptibility to advertisement of a
new product. The long-term demand depends on the long-term
income trends, availability of better substitutes, sales promotion,
and consumer credit facility. The short-term and lcmg-term
concepts of demand are useful in designing new products for
established producers, choice of products for the new
entrepreneurs, in pricing policy and in determining advertisement
expenditure.
DETERMIN!\NTS OF MARKET DEMAND
The knowledge of the determinants of market demand for a product
and the nature of relationship between the demand and its
determinants proves very helpful in analysing and estimating
demand for the product. It may be noted at the very outset that a
host of factors determines the demand for a product. In general,
following factors determine market demand for a good:
Price of the good- .
Price of the related goods-substitutes, complements and
supplements
Level of consumers' income
Consumers' taste and preference
Advertisement of the product
Consumers' expectations about future price and
supply position
Demonstration effect and 'bend-wagon effect’
Consumer-credit facility
Population of the country
Distribution pattern of national income.
These factors also include factors such as off-season discounts
and gifts on purchase of a good, level of taxation and general social
and political environment of the country. However, all these factors
are not equally important. Besides, some of them are not
quantifiable. For example, consumer's preferences, utility,
demonstration effect and expectations, are difficult to measure.
However, both quantifiable and non-quantifiable determinants of
demand for a product will be discussed.
1. Price of the Product
The price of a product is one of the most important determinants of
demand in the long run and the only determinant in the short run.
The price and quantity demanded are inversely related to each
other. The law of demand states that the quantity demanded of a
good or a product, which its consumers would like to buy per unit of
time, increases when its price falls, and decreases when its price
increases, provided the other factors remain' same. The assumption
'other factors remaining same' implies that income of the
consumers, prices of the substitutes and complementary goods,
consumer's taste and preference and number of consumers remain
unchanged. The price-demand relationship assumes a much greater
significance in the oligopolistic market in which outcome of price
war between a firm and its rivals determines the level of success of
the firm. The firms have to be fully aware of price elasticity of
demand for their own products and that of rival firm's goods.
2. Price of the Related Goods or Products
The demand for a good is also affected by the change in the price
of its related goods. The related goods may be the substitutes or
complementary goods.
Substitutes
Two goods are said to. be substitutes of each other if a change in
price of one good affects the deinand for the other in the same
direction. For instance goods X and Y are considered as substitutes
for each other if a rise in the price of X increase demand for Y, and
vice versa. Tea and coffee, hamburgers and hot-dog, alcohol and
drugs are some examples of substitutes in case of consumer goods
by definition, the relation between demand for a product and price
of its substitute is of positive nature. When, price of the substitute of
a product (tea) falls (or increase), the demand for the product falls
(or increases). The relationship of this nature is shown in Figure 2.1
and 2.2.
Complementary Goods
A good is said to be a complement for another when it complements
the use of the other or when the two goods are used together in
such a way that their demand changes (increases or decreases)
simultaneously. For example, petrol is a complement to car and
scooter, butter and jam to bread, milk and sugar to tea and 1 coffee,
mattress to cot, etc. Two goods are termed as complementary to
each other -i if an increase in the price of one causes a decrease in
demand for the other. By definition, there is an inverse relation
between the demand for a good and the price of its complement.
For instance, an increase in the price of petrol causes a decrease in
the demand for car and other petrol-run vehicles and vice versa
while other thing's remaining constant. The nature of relationship
between the demand
for a product and the price of its complement is given in Figure 2.2.
3. Consume's Income
Income is the basic determinant of market demand since it
determines the purchasing power of a consumer. Therefore,
people with higher current disposable income spend a larger
amount on goods and services than those with lower income.
Income-demand relationship is of more varied nature than that
between demand and its other determinants. While other
determinants of demand, e.g., product's own price and the price
ohts substitutes, are more significant in the short-run, income as
a determinant of demand is equally important in both short run
and long run. Before proceeding further to discuss income-
demand relationships, it will be useful to note that consumer
goods of different nature have different kinds of relationship with
consumers having different levels of income. Hence, the
managers need to be fully aware of the kinds of goods they are
dealing with and their relationship with the income of consumers,
particularly about the assessment of both existing and
prospective demand for a product.
For the purpose of income-demand analysis, goods and serv:ices
maybe grouped under four broad categories, which ate: (a)
essential consumer goods, (b) inferior goods, (c) normal goods, and
(d) prestige or luxury goods. To understand all these terms, it is
essential to understand the relationship between income and
different kinds of goods.
Esscntial Consumcr Goods (ECG): The goods and services of
this category are called 'basic needs' and are consumed by all
persons of a society such as food-grains, salt, vegetable oils,
matches, cooking fuel, a minimum clothing and housing.
Quantity demanded for these goods increases with increase in
consumer's income but only up to certain limit, even though
the total expenditure may increase in accordance with the
quality of goods consumed, other factors remaining the same.
The relationship between goods of this category and
consumer's income is shown by the curve ECG in Figure 2.3.
As the curve shows, consumer's demand for essential goods
increases only until his income rises to OY2. It tends to
saturate beyond this level of income.
Inferior goods: Inferior goods are those goods whose demand
decreases with the increase in consumer's income. For
example millet is inferior to wheat and rice; bidi (indigenous
cigarette) is inferior to cigarette, coarse, textiles are inferior to
refined ones, kerosene is inferior to cooking gas and travelling
by bus is inferior to travelling by taxi. The relation between
income and demand for an inferior good is shown by the curve
IG in Figure 2.3 under the assumption that other determinants
of demand remain the same demand for such goods rises only
up to a certain level of income, i.e., OY1 and declines as
income increases beyond this level.
Normal goods: Normal goods are those goods whose demand
increases with increaseiri the consumer income. For example,
clothings, household furniture and automobiles. The relation
between income and demand for normal goods is shown by
the curve NG in Figure 2.3. As the curve shows, demand for
such goods increases with the increases in consumer income
but at different rates at different levels of income. Demand for
normal goods increases rapidly with the increase in the
consumer's income but slows down with further increase in
income. It should be noted froms Figure 2.3 that up to certain
level of income (YI) the relation between income and demand
for all type of goods is similar. The difference is of only
degree. The relation becomes distinctly different beyond YI
level of income. Therefore, it is important to view the income-
demand relations in the light of the nature of product and the
level fconsumer's income.
Prestige and luxury goods: Prestige goods are those goods,
which are consu!TIed mostly by rich section of the society, e.g.,
precious stones, antiques, rare paintings, luxury cars and such
other items of show-bff. Whereas luxury goods include
jewellery, costly brands of cosmetics, TV sets, refrigerators,
electrical gadgets and cars. Demand for such goods arises
beyond a certain level of consumer's income, i.e., consumption
enters the area of luxury goods. Producers of such goods, while
assessing the demand for their goods, should consider the
income changes in the richer section of the society and not
only the per capita income. The relation between income and
demand for such goods is shown by the curve LG in Figure 2.3.
4. Consumer's taste and preference
Consumer's taste and preference play an important role in
detennihing demand for a product. Taste and preference depend,
generally, on the changing. life-style, social customs, religious
values attached to a good, habi of the people, the general levels of
living of the society and age and sex of the consumers. Change in
these factors changes consumer's taste and preferences. As a
result, consumers reduce or give up the consumption of some
goods and add new ones to their consumption pattern. For
example, following the change in fashion, people switch their
consumption pattern from cheaper, old-fashioned goods to costlier
‘mod’ goods, as long as price differentials are proportionate with
their preferences. Consumers are prepared to pay higher prices for
'mod goods' even if their virtual utility is the same as that of old-
fashioned goods. The manufacturers of goods and services that are
subject to frequent change in fashion and style, can take
advantage of this situation in two ways: (i) they can make quick
profits by designing new models of their goods and popularising
them through advertisement, and (ii) they can plan production in
abetter way and can even avoid over-productiorlifthey keep an eye
on the changing fashions.
5. Advertisel11ent Expenditure
Advertisement costs are incurred with the objective of increasing
the demand for the goods. This is done in the following ways:
By informing the potential consumers about the availability of
the goods.
By showing its superiority to the rival goods.
By influencing consumers' choice against the rival goods, and
By setting fashions and changing tastes.
The impact of such effects shifts the demand curve upward to
the
right.
In other words, when other factors' remain same, the
expenditure on advertisement increases the volume of sales to the
same extent. The relation between advertisement outlay and sales
is shown in Figure 2.4.
Assumptions
Therelatiqnship between demand and advertisement cost as shown
in Figure 2.4 is based on the following assumptions:
Consumers are fairly sensitive and responsive to various
modes
of advertisement.
The rival firms do not react to the advertisements made by a
firm.
The level of demand has not already reached the saturation
point. Advertisement beyond this point will make only
marginal impact on demand.
Per unit cost of advertisement added to the price does not
make the price prohibitive for consumers, as compared
particularly to the price of substitutes.
Others determinants of demand, e.g., income and tastes, etc.,
are not operating in the reverse direction.
In the absence of these conditions, the advertisement effect on
sales may be unpredictable.
6. Consumers’ Expectations
Consumers’ expectations regarding the future prices, income and
supply position of goods play an important role in determining the
demand for goods and services in the short run. If consumers
expect a rise in the price of a storable good, they would buy more of
it at its current price with a view to avoiding the possibility of price
rise future. On the contrary, if consumers expect a fall in the price of
certain goods, they postpone their purchase with a view to take
advantage of lower prices in future, mainly in case of non-essential
goods. This behaviour of consumers reduces the current demand for
the goods whose prices are expected to decrease in future.
Similarly, an expected increase in income increases the demand for
a product. For example, announcement of ‘dearness allowance’,
bonus and revision of pay scale induces increase in current
purchases. Besides, if scarcity of certain goods is expected by the
consumers on account of reported fall in future production, strikes
on a large scale and diversion of civil supplies towards the military
use causes the current demand for such goods to increase more if
their prices show an upward trend. Consumer demand more for
future consumption and profiteers demand more to make money
out of expected scarcity.
7. Demonstration Effect
When new goods or new models of existing ones appear in the
market, rich people buy them first. For instance, when a new model
of car appears in the market, rich people would mostly be the first
buyer, Colour TV sets and VCRs were first seen in the houses of the
rich families some people buy new goods or new models of goods
because they have genuine need for them. Some others do so
because they want to exhibit their affluence. But once new goods
come in fashion, many households buy them not because they
have a genuine need for them but because their neighbors have
bought the same goods. The purchase made by the latter category
of the buyers are made out of such feelings' as jealousy,
competition, equality in the peer group, social inferiority and the
desire to raise their social status. Purchases made on account of
these factors are the result of what economists call 'demonstration
effect' or the 'Band-wagon-effect.' These effects have a positive
effect on demand. On the contrary, when goods become the thing
of common use, some people, mostly rich, decrease or give up the
consumption of such goods. This is known as 'Snob Effect'. It has a
negative effect'on the demand
for the related goods.
8. Consumer-Gredit Facility
Availability of credit to the cansumers fram the sellers, banks,
relatians and friends encourages the conSumers to buy more than
what they would buy in the aosence of credit availability.
Therefore, the consumers who can borrow more can consume
more than those who cannot borrow. Credit facility affects mostly
the demand"for durable goods, particularly those, which require
bulk payment at the time of purchase. The car-loan facility may be
one reason why Delhi has more cars than Calcutta, Chennai and
Mumbai. Therefore, the managers who are assessing the
prospective demand for their goods should take into account the
availability of credit to the consumers.
9. Population of the Country
The Jotal domestic demand for a good of mass consumption
depends also on the size' of the population. Therefore, larger the
population larger will be the demand for a product, when price, per
capita income, taste and preference are given. With an increase or
decrease in the size of population, employment percentage
remaining the same, demand for the product will either increase or
decrease.
10. Distribution of National Income
The level of national income is the basic determinant of the market
demand for a good. Therefore, pig her the national income higher
will be the demand for all normal goods and services. Apart from
this, the distribution pattern of the national income is also an
important determinant for demand of a good. If national income is
evenly distributed, market demand for normal goods will be the
largest. If national income is unevenly distributed, i.e., if majority of
population belongs to the lower income groups, market demand for
essential goods, including inferior ones, will be the largest whereas
the demand for other kinds of goods will be relatively less.

LESSON - 3
COST CONCEPTS
Business decisions are generally taken on the basis of money values
of the inputs and outputs. The cost production expressed in
monetary terms is an important factor in almost all business
decisions, specially those pertaining to (a) locating the weak points
in production management; (b), minimising the cost; (c) finding out
the optjmum level of output; and (d) estimating or projecting the
cost of business operations. Besides, the term 'cost' has different
meanings under different settings and is subject to varying
interpretations. It is therefore essential that only relevant concept of
costs is used in the business decisions.
CONCEPT OF COST
The concepts of cost, which are relevant to business operations and
decisions, can be grouped, on the basis of their purpose, under two
overlapping categories such as concepts used for accounting
purposes and concepts used in economic analysis of business
activities.
SOME ACCOUNTING CONCEPTS OF COST
Opportunity Cost and Actual Cost
Opportunity cost is the loss incurred due to the unavoidable
situations such as scarcity of resources. If resources were unlimited,
there would be no need to forego any income yielding opportunity
and, therefore, there would be no opportunity cost. Resources are
scarce but have alternative uses with different returns, Resource
owners who aim at maximising of income put their scarce resources
to their most productive use and forego the income expected from
the second best use of the resources. Thus, the opportunity cost
may be defined as the expected returns from the second best use of
the resources foregone due to the scarcity of resources. The
opportunity cost is also called the alternative cost.
For example, suppose that a person hps a sum of Rs. lOO,OOO
for which he has only two alternative uses. He can buy either a
printing machine or, alternatively, a lathe machine. From printing
machine, he expects an annual income of Rs. 20,000 and from the
lathe, Rs. 15,000. If he is a profit maximising investor, he would
invest his tnoney in printing machine and forego the expected
income from the lathe. The opportunity cost of his income from
printing machine is,· the expected income from the lathe machine,
i.e., Rs. l5,000. The opportunity cost arises because of the foregone
opportunities. Thus, the opportunity cost of using resources in
the'Printing business is the best opportunity ahdthe expected
return from the lathe machine is the second best alternative. In
assessing the alternative cost, both explicit and implicit costs are
taken into account.
Associated with the concept of opportunity cost is the concept
of economic rent or economic profit. In our example, economic rent
of the printing machine is the excess of its earning over the income
expected from the lathe machine (i.e., Rs. 20,000 - Rs. 15,000 =
Rs. 5,000). The implication of this concept for a businessman is
that investing in printing machine is preferable as long as its
economic rent is greater than zero. Also, if firms have knowledge
of the economic rent of the various alternative uses of their
resources, it will be helpful for them to choose the best Investment
A venue. In contrast to opportunity cost, actual costs are those
which are actually incurred by the firm in the payment for labour,
material, plant, building, machinery, equipments, travelling and
transport, advertisement, etc. The total money expenditures,
recorded in the' books of accounts are, the actual costs, Therefore,
the actual cost comes under the accounting concept.
Business Costs and Full Costs
Business.costs include all the expenses, which are incurred to carry
out a business. The concept of business costs is similar to the
actual or the real costs. Business costs include all the payments
and' contractual obligations made by the firm together with the
book cost of depreciation on plant and equipment. These cost
concepts are used for calculating business profits and losses, for
filing returns for income tax and for other legal purposes. The
concept of full costs, include business costs, opportunity cost and.
normal profit. As stated earlier the opportunity cost includes the
expected earning from the second best use of the resources, or the
market rate of interest on the total money capital and the value of
entrepreneur's own services, which are not charged for'in the
current business. Normal profit is a necessary minimum earning in
addition to the opportunity cost, which a firm must get to remain in
its present occupation.
Explicit and Implicit or Imputed Costs
Explicit costs are those, which fall under actual or business costs
entered in the books of accounts. For example, the payments for
wages and salaries, materials, licence fee, insurance premium and
depreciation charges etc. These costs involve cash payment and,
are recorded in normal accounting practices. In contrast with these
costs, there are other costs, which neither take the form of cash
outlays, nor do they appear in the accounting system. Such costs
are known as implicit or imputed costs. Implicit costs may be
defined as the earning expected froin thesecond best alternative
use of resources. For example, suppose an entrepreneur does not
utilise his services in his own business and works as a manager in
·some other firm on a salary basis. If he starts his own business, he
foregoes his salary as a manager. This loss of salary is the
opportunity cost of income from his business. This is an implicit cost
of his business. The cost is implicit, because the entrepreneur
suffers the loss, but does not charge it as the explicit cost of his own
business. Implicit costs are not taken into account while calculating
the loss or gains of the business, but they form an important
consideration in whether or not a factor would remain in its present
occupation. The explicit and implicit costs together make the
economic cost.
Out-of-Pocket and Book Costs
The items of expenditure, which involve cash payments or cash
transfers recurring and non-recurring are known as out-of-pocket
costs. All the explicit costs such as wage, rent, interest and
transport expenditure. On the contrary, there are actual business
costs, which do not involve cash payments, but a provision is made
for them in the books of account. Thes costs are taken into account
while finalising the profit and loss accounts. Such expenses are
known as book costs. In a way, these are payments that the firm
needs to pay itself such as depreciation allowances and unpaid
interest on the businessman's own fund.
Fixed and Variable Costs
Fixed costs are those, which are fixed in volume for a given output.
Fixed cost does not vary with variation in the output between zero
and any certain level of output. The costs that do not vary for a
certain level of output are known as fixed cost. The fixed costs
include cost of managerial and administrative staff, depreciation of
machinery, building and other fixed assets and maintenance of
land, etc.
Variable costs are those, which vary with the variation in the
total output. They are a function of output. Variable costs inclue
cost of raw materials, running cost on fixed capital, such as fuel,
repairs, routine maintenance expenditure, direct labour charges
associated with the level of output and the costs of all other inputs
that vary with the output.
Total, Average and Marginal Costs
Total cost represents the value of the total resource requirement for
the production of goods and services. It refers to the total outlays of
money expenditure, both explicit and implicit, on the resources
used to produce a given level of output. It includes both fixed and
variable costs. The total cost for a given output is given by the cost
function.
The Average Cost (AC) of a firm is of statistical nature and is not
the actual cost. It is obtained by dividing the total cost (TC) by the
total output (Q), i.e.,
AC =TC
= average cost Q
Marginal cost is the addition to the total cost on account of
producing an additional unit of the product. Or marginal cost is the
cost of marginal unit produced. Given the cost function, it may be
defined as
These cost concepts are discussed in further detail in the
following section. Total, average and marginal cost concepts are
used in economic analysis of firm's producti on activities.
Short-run and Long-run Costs
Short-run and long-run cost concepts are related to variable and
fixed costs, respectively, and often appear in economic analysi.s
interchangeably. Short-run costs are those costs, which change with
the variation in output, the size of the firm remaining the same. In
other words, short-run costs are the same as variable costs. Long-
run costs, on the other hand, are the costs, which are incurred on
the fixed assets like plant, building, machinery, etc. Such costs
have long-run implication in the sense that these are not used up in
AC=aTC
aQ
the single batch of production.
Long-run costs are, by implication, same as fixed costs. In the
long-run, however, even the fixed costs become variable costs as
the size of the firm or scale of production increases. Broadly
speaking, the short-run costs are those associated with variables in
the utilisation of fixed plant or other facilities whereas long-run
costs are associated with the changes in the size and type of plant.
Incremental Costs and Sunk Costs
Conceptually, increment natal costs are closely related to the
concept of marginal sot. Whereas marginal cost refers to the cost of
the macgmalunit of output, incremental cost refers to the total
additional cost associated with the marginal batch of output. The
concept of incremental cost is based on a specific and factual
principle. In the real world, it is not practicable for lack of perfect
divisibility of inputs to employ factors for each unit of output
separately. Besides, in the long run, firms expand their production;
hire more men, materials, machinery, and equipments. The
expenditures of this nature are the incremental costs, anq not the
marginal cost. Incremental· costs also arise owing to the change in
product lines, addition or introduction of a new product,
replacement of worn out plan and machinery, replacement of old
technique of production with a new one, etc.
The sunk costs are those, which cannot be altered, increased or
decreased, by varying the rate of output. For example, once it is
decided to make incremental investment expenditure and the
funds are allocated and spent, all the preceding costs are
considered to be the sunk· costs since they accord to the prior
commitment and cannot be revised or reversed when there is
change in market conditions orchange in business decisions.
Historical and Replacement Costs
Historical cost refers to the cost of an asset acquired· in the past
whereas replacement cost refers to the outlay, which has to be
made for replacing an old asset. These concepts own their
sigtlificance to unstable nature of price behaviour. Stable prices
over a period of time, other things given, keep historical and
replacement costs on par with each other. Instability in asset
prices, however, makes the two costs differ from each other.
Historical cost of assets is used for accounting purposes, in
the assessment of net worth of the firm.
Private and Social Costs
We have so far discussed the cost concepts that are related to the
working of the firm and those which are used in the cost-benefit
analysis of the business decision process. There are, however,
certain other costs, which arise due to functioning of the firm but
do not normally appear in business decisions. Such costs are
neither explicitly borne by the firms. The costs of this category are
borne by-the society. Thus, the total cost generated by a firm's
working may be divided into two categories:
• Those paid out or provided for by the firms,
• Those not paid or borne by the firm.
The costs that are not borne by the firm include use of resouces
freely available and the disutility created in the process of
production. The costs of the former category are known as private
costs and of the latter category are known as external or social
costs. A few examples of social cost are: Mathura Oil Refinery
discharging its wastage in the Yamuna River causes water pollution.
Mills and factories located in city cause air pollution by emitting
smoke. Similarly, plying cars, buses, trucks, etc., cause both air and
noise pollution; Such pollutions cause tremendous health hazards,
which involve health cost to the society as it whole Thes'e costs are
termed external costs from the firm's point of view and social cost
from the society's point of view. The relevance of the social costs
lies in understandipg the overall impact of firm's working on the
society as a whole and in working out the social cost of private
gains. A further distinction between private cost and social cost
therefore, requires discussion.
Private costs are those, which are actually incurred or
provided by an individual or a firm on the purchase of goods and
services from the market. For a firm, all the actual costs both
explicit and implicit are private costs. Private costs are the
internalised cost that is incorporated in the firm's total cost of
production.
Social costs, on thehand refer to the total cost for the society
on account of production ofa commodity. Social cost can be the
private cost or the external cost. It includes the cost of resources for
which the firm is not compelled to pay a price such as rivers and
lakes, the public, utility services like roadways and drainage
system, the cost in the form of disutility created in through air,
water and noise pollution. This category is generally assumed to be
equal to total private and public expenditures. The private and
public expenditures, however, serve only as an indicator of public
disutility. They do not give exact measure of the public disutility or
the social costs.
COST-OUTPUT RELATIONS
The previous section discussed the variou cost concepts, which help
in the business decisions. The following section contains the
discussion of the behaviour of costs in relation to the change in
output. This is, in fact, the theory of production cost.
Cost-output relations play an importai)t role in business
decisions relating to cost minirnisalioil"Of'profiHnaximisation and
optimisation of output. Cost-output relations are specified through a
cost function expressed as
T(C) = f(Q) (1)
where,
TC = total cost
Q = quantity produced
Cost functions depend on production function and market-
supply function of inputs. Production function specifies the technical
relationship between the input, and the output. Production function
of a firm combined with the supply function of inputs or prices of
inputs determines the cost function of the firm. Precisely, cost
function is a function derived from the production function and the
market supply function. 'Depending on whether short or long-run is
considered for the production, there are two kinds of cost functions:
such as short-run cost-function and long-run cost function. Cost-
output relations in relation to the changing level of output will be
discussed here u.nder both kinds of cost-functions.
Short-run Cost Output Relations
The basic analytical cost concepts used in the analysis of cost
behaviour are total average and marginal costs. The totalcost (TC)
is defined as the actual cost that must be incurred to produce a
given quantity of output. The short-run TC is composed of two
major elements: total fixed cost (TFC) and total variable cost (TVC).
That is, in the short-run,
TC = TFC + TVC (2)
As mentioned earlier, TFC (i.e" the ·cost·of plant, building,
equipment, etc.) remains fixed in the short-run, where as TVC varies
with the variation in the output.
For a given quantity of output (Q), the average total cost,
(AC), average fixed cost (AFC) and, average var!able cost (AVC) can
'be defined as follows:
AC =TC
=TFC + TVC
Q Q
TFC
AFC = Q
AVC =TVC
Q
and AC = AFC +AVC (3)
Marginal cost (MC) is defined as the change in the total cost divided
by the change in the total output, i.e.,
MC =∆TC
oraTC
∆Q aQ
(4)
Since ∆TC = ∆TFC + ∆TVC and, in the short-run, ∆TFC = 0,
therefore, ∆TC=∆TVC
Furthermore, under marginality concept, where ∆Q = 1,MC =
∆TVC.
Cost Function and Cost-output Relations
The concepts AC, AFC and AVC give only a static relationship
between cost and output in the sense that they are related to a
given output. These cost concepts do not tell us anything about cost
behaviour, i.e., how AC, A VC and AFC behave when output
changes. This can be understood better with a cost function of
empirical nature.
Suppose the cost function (I) is specified as
TC = a + bQ - CQ2 + dQ3 (5)
(where a = TFC and b, c and d are variable-cost parameters)
And also the cost function is empirically estimated as
TC = 10 + 6Q - 0.9Q2 + 0.05Q3 (6)
and TVC = 6Q - 0.9Q2 + 0.05Q3 (7)
The TC and TVC, based on equations (6) and (7), respectively,
have been calculated for Q = I to 16 and is presented in Table 3.1.
The TFC, TVC and TC have been graphically presented in Figure 3.1.
As the figure shows, TFC remains fixed for the whole range of
output, and hghce, takes the form of a horizontal line, i.e., TFC. The
TVCcurve shows that the total variable cost first increases ata'i
decreasing rate and then at an increasing rate with the increase it
the total output. The rate of increase can be obtained from the
slope of TVC curve. The pattemof change in the TVC stems directly
from the law of increasing and diminishing returns to the variable
inputs. As output increases, larger quantities of variable inputs are
required to produce the same quantity of output due to diminishing
returns. This causes a subsequent increase in the variable cost for
producing the same output. The following Table 3.1 shows the cost
output relationship.
Table 3.1: Cost Output Relations

From equations (6) and (7), we may derive the behavioural
equations for AFC, AVC and AC. Let us first consider AFC.
Average Fixed Cost (AFC)
As already mentioned, the costs that remain fixed for a certain level
of output make the total fixed cost in the short-run. The fixed cost is
represented by the constant term 'a' in equation (6). We know that
AFC =
TFC (8)
Q
Substituting 10 for TFC in equation (8), we get
AFC =
10 (9)
Q
Equation (9) expresses the behaviour of AFC in relation to
change in Q. The behaviour of AFC for Q from 1 to 16 is given in
Table 3.1 (col. 5) and is presented graphically by the AFC curve in
the Figure 3.1. The AFC curve is a rectangular hyperbola.
Average Variable Cost (AVC)
As defined above,
AVC =
TVC
Q
Given the TVC function in equation 7, we may express AVC as follows:
AVC =
6Q-0.9Q2+0.05Q3
= 6- 0.9Q+0.05Q3
(10)Q
Having derived the A VC function (equation 10), we may easily
obtain the behaviour of A VC in response to change in Q. The
behaviour of A VC for Q from I to 16 is given in Table 3.1 (co 1. 6),
and is graphically presented in Figure 3.2 by the A VC curve.
Critical Value of A VC
From equation (10), we may compute the critical value or Q in respect of A Vc. The
critical value of Q (in respect of A VC) is that value of Q at which A VCis minimum.
The Ave will be minimum when its decreasing rate of change is equal to zero. This
can be accomplished by differentiating equation (10) and setting it equal to zero.
Thus, critical value of Q can be obtained as
Q=aAVC
= 0.9+0.10Q=0
(11)
aQ
Q= 9
Thus, the critical value of Q=9. This can be verified from Table
3.1
Average Cost (AC)
The average cost in defined as
AC =TC
Q
Substituting equation (6) for TC in above equation, we get
AC =
10+6Q-09Q2+0.05Q3
(12a)
Q
=
10
+ 6-0.9Q+0.05Q2Q
The equation (l2a) gives the behaviour of AC in response to
change in Q. The behaviour of AC for Q from I to 16 is given in Table
3.1 and graphically presented in Figure 3.2 by the AC-curve. Note
that AC-curve is U-shaped.
From equation (12a), we may easily obtain the critical value of Q in
respect of AC. Here, the critical valuepf Q in respect of AC is one at
which AC is minimum. This can be obtained by differentiating
equation (l2a) and setting it equal to zero. This, critical vallie of Q in
respect of AC is given by
aAC
=
10- 0.9 + 0.1Q = 0
(12b)aQ Q2
This equation takes the form of a quadratic equation as
-10 – 0.9Q2 + 0.1Q3 = 0
or, Q3 – 9Q2 = 100 = 0
By solving equation (12b), we get
Q = 10
Thus, the critical value of output in respect of AC is 10. That is,
AC reaches its minimum at Q = 10. This can be verified from Table.
3.1 shows short-run cost curves.
Marginal Cost (MC)
The concept of marginal cost (MC) is particularly useful in economic
analysis. MC is technically the first derivative of TC function. That is,
MC =aTC
aQ
Given the TC function as in equation (6), the MC function can be obtained as
aTC
= 6-1.8Q+0.15Q2 (13)aQ
Equation (13) represents the behaviour of MC. The behaviour of
MC for Q from 1 to 16 computed as MC = TCn - TCn- i is given in
Table 3.1 (col. 8) and graphically presented by MC-curve in Figure
3'.2. The critical 'value of Q in respect of MC is 6 or 7. It can be
seen from Table 3.1.
One method of solving quadratic equation is to factorise it and
find the solution.
Thus, Q3 – 9Q2 – 100 = 0
(Q – 10) (Q2 + Q + 10) = 0
For this to hold, one of the terms must be equal to zero,
Suppose (Q2 + Q + 10) = 0
Then, Q – 10 = 0 and Q = 10.
COST CURVES AND THE LAWS OF DIMINISHING RETURNS
We now return to the laws of variable proportions and explain it
through the .cost curves. Figures 3.1 and 3.2 clearly bring out the
short-term laws of production, i.e., the laws of diminishing returns.
Let us recall the law: it states that when more and more units of a
variable input are applied to those inputs which are held constant,
the returns from the marginal units of the variable input may
initially increase but will eventually decrease. The same law can also
be interpreted in term's of decreasing and increasing costs. The law
can then be stated as, if more and more units of a variable inputs
are applied to the given amount of a fixed input, the' marginal cost
initially decreases, but eventually increases. Both interpretations of
the law yield the same information: one in terms of marginal
productivity of the variable input, and the other, in terms of the
marginal cost. The former is expressed through production function
and the latter through a cost function.
Figure 3.2 represents the short-run laws of returns in terms of
cost of production. As the figure shows, in the initial stage of
production, both AFC and AVC are declining because of internal
economies. Since AC = AFC + AVC, AC is also declining, this shows
the operation of the law of increasing returns. But beyond a certain
level of output (i.e., 9 units in out example), while AFC continues to
fall, AVC starts increasing because of a faster increase in the TVC.
Consequently, the rate of fall in AC decreases. The AC reaches its
minimum when output increases to 10 units. Beyond this level of
output, AC starts increasing which shows that the law of diminishing
returns comes in operation. The MC, curve represents the pattern of
change in both the TVC and TC curves due to change in output. A
downward trend in the MC shows increasing marginal productivity of
the variable input mainly due to internal economy resulting from
increase in production. Similarly, an upward trend in the MC shows
increase in TVC, on the one hand, and decreasing marginal
productivity of the variable input, on the other.
SOME IMPORTANT COST RELATIONSHIPS
Some important relationships between costs used in analysing the
short-run cost behaviour may now be summed up as follows:
As long as AFC and AVC fall, AC also falls because AC = AFC
+AVC.
When AFC falls but A VC increases, change in AC depends on
the rate of change in AFC and AVC then any of the following
happens:
ifthereisdecrease in AFC and increase in A VC, AC falls,
if the decrease on AFC is equal to increase in Ave, AC
remains constant, and
if the d~crease in AFC is less than increase in A VC, AC
increases.
The relationship between AC and MC is of varied nature. It may
be described as follows:
When MC falls, AC follows, over a certain range of initial
output. When MCis failing, the rate of fall in MC is greater
than that of AC This is because in case of MC the decreasing
marginal cost is attributed, : to a single marginal unit while;
in case of AC, the decreasing marginal cost is distributed
overall the entire output. Therefore, AC decreases at a lower
rate than MC.
Similarly, when MC increase, AC also increases but at a
lower rate fbr the reason given in'the above point. There is
however a range of output over which this relationship does
not exist. For example, compare the behaviour of MC and
AC over the range of output frbm 6 units to 10 units (see
Figure 3.2). Over this range of ~utput, MC begins to
increase while AC continues to decrease. The reason for this
can be seen in Table. 3.1. When MC starts increasing, it
increases at a relatively lower rate, which is sufficient only
to reduce the rate of decrease in AC, i.e., not sufficient to
push the AC up. That is why AC continues to fall over some
range of output even, if MC falls.
MC iJ1tetsects AC at its minimum point. This is simply a
mathematical relationship between MC and AC curves when
both of them are obtained from the same TC function. In
simple words, when AC is at its minimum, then it is neither
increasing nor decreasing it is constant. When AC is
constant, AC = MC.
Optimum Output in Short-run
An optimum level of output is the one, which can be produced at a
minimum or least average cost, given the required technology is
available. Here, the least'tcost' combination of inputs can be
understood with the help of isoquants and isocosts. The least-cost
combination of inputs also indicates the optimum level of output at
given investment and factor prices. The AC and MC cost Curves can
also be used to find the optimum level of output, given the size of
the plant in the short-run. The point of intersection between AC and
MC curves deterinines the minimum level of AC. At this level of
output AC = MC. Production beloW or beyond thislevelwill be in
optimal. If production is less than 10 units (Figure 3.2) it will leave
some scope for reducing AC by producing more, because MC < AC.
Similarly, if production is greater than 10 units, reducing output can
reduce AC. Thus, the cost curves can be useful in finding the
optimum level of output. It may be noted here that optimum level of
output is not necessarily the maximum profit output. Profits cannot
be known unless the revenue curves of firms are known.
Long-run Cost-output Relations
By definition, in the long-run, all the inputs become variable. The
variability of inputs is based on the assumption that, in the long run,
supply of all the inputs, including those held constant in the short-
run, becomes elastic. The firms are, therefore, in a position to
expand the scale of their production by hiring a larger quantity of all
the inputs. The long-run cost-output relations, therefore, imply the
relationship between the changing scale of the firm and the total
output; conversely in the short-run this relationship is essentially
one between the total output and, the variable cost (labour). To
understand the long-run costoutput relations (lnd to derive long-run
cost curves it will be helpful to imagine that a long run is composed
of a series of short-run production decisions. As a' corollary of this,
long-run cost curves are composed of a series of short-run cost
curves. We may now derive the long-run cost curves and study
their' relationship with output.
Long-run Total Cost Curve (LTC)
In order to draw the long-run total cost curve, let us begin with a
short-run situation. Suppose that a firm having only one-plant has
its short-mn total cost curve as given-by STCl in panel (a) of Figure
3.3. In this example if the firm decides to add two more plants to its
size over time, one after the other then in accordance two more
short-run total cost curves are added to STCl in the manner shown
by STC2 and STC3 in Figure 3.3 (a):. The LTC can now be drawn
through the minimum points of STCl, STC2 and STC3 as shown by the
LTC curve
corresponding to each STC.
Long-run Average Cost Curve (LAC)
Combining the short-run average cost curves (SACs) derives the
long-run average cost curve (LAC). Note that there is one SAC
associated with each STC. Given the STC1 STC2, and STC3 curves in
panel (a) of Figure 3.3, there are three corresponding SAC curves as
given by SAC1 SAC2 arid SAC3 curves in panel (b) of Figure 3.3. Thus,
the firm has a series of SAC curves, each having a bottom point
showing the minimum SAC. For instance, C1Q1 is the minimum AC
when the firm has only one plant. The AC decreases to C2Q2 when
the second plant is added and then rises to C3Q3after the inclusion
of the third plant. The LAC carl be drawn through the bottom of
SAC1 SAC2 and SAC3 as shown in Figure·3.3 (b) The LAC curve is also
known as ‘Envelope Curve' or 'Planning Curve' as it serves as a
guide to the entrepreneur in his planning to expand production.
The SAC curves can be derived from the data given in the STC
schedule, from STC function or straightaway from the LTC-curve.
Similarly, LAC can be derived from LTC-schedule, LTC function or
from LTC-curve. The relationship between LTC and output, and
between LAC and output can now be easily derived. It is obvious.
from the LTC that the long-run cost-output relationship is similar to
the short-run cost-output relationship. With the subsequent
increase in the output, LTC first increases at a decreasing rate, and
then at an increasing rate. As a result, LAC initially decreases until
the optimum utilisation of the second plant and then it begins to
increase. From these relations are drawn the 'laws of returns to
scale'. When the scale of the firm expands, unit cost of production
initially decreases, but it ultimately increases as shown in Figure
3.3 (b).
Long-run Marginal Cost Curve
The long-run marginal, cost curve (LMC) is derived from the short-
run marginal cost curves (SMCs). The derivation of LMC is illustrated
in Figure 3.4 in which SAC3'and LAC arethe same as'in Figure 3.3(b).
To derive the LMC3, consider the points of tangency between SAC3
and the LAC, i.e., points A, Band C. In the long-run production
planning, these points determine the output levels at the different
levels of production. For example, if we draw perpendiculars from
points A, Band C to the X-axis, the corresponding output levels will
be OQ1 OQ2 and OQ3 The perpendicular AQ1 intersects the SMC1 at
point M. It means that at output BQ2, LMC, is MQ1. If output
increases to OQ2, LMC rises to BQ2. Similarly, CQ3 measures the LMC
at output OQ3. A curve drawn through points M3B and N, as shown
by the LMC, represents the behaviour of the marginal cost in the
long run. This curve is known as the long-run marginal cost curve,
LMC. It shows the trends in the marginal cost in response to the
change in the scale of production.
Some important inferences may be drawn from Figure 3.4. The
LMC must be equal to SMC for the output at which the
corresponding SAC is tangent to the LAC. At the point of tangency,
LAC = SAC. For all other levels of output (considering each SAC
separately), SAC > LAC. Similarly, for all levels of outout
corresponding to LAC = SAC, the LMC = SMC. For all other levels
output, i:he LMC is either greater or less than the SMC. Another
important point to notice is that the LMC intersects LAC when the
latter is at its minimum, i.e., point B. There, is one and only one
short-run plant size whose minimum SAC coincides with the
minimum LAC. This point is B where, SAC2 = SMC2 = LAC = LMC.
Optimum Plant Size and Long-run Cost Curves
The short-run cost curves are helpful in showing how a firm can
decide on the optimum utilisation of the plant-which is the fixed
factor; or how it can determine the least-cost output level. Long-run
cost curves, on the other hand, can be used to show how the
management can decide on the optimum size of the firm. An
Optimum size of a firm is the one, which ensures the most efficient
utilisation of resources. Given the state: of technology overtime,
there is technically a unique size of the firm and lever of output
associated with the least cost Concept. This uriique size of the firm
can be obtained with the help of LAC and LMCIn Figur 3.4 the
optimum size consists of two plants, which produce OQ2 units of a
produd, at minimum long-run average cost (LAC) of BQ2.
The downtrend in the LAC ihdicates that until output reaches
the level of OQ2, the firm is of non-optimal size. Similarly, expansion
of the firm beyond production capacity OQ2 causes a rise in SMC as
well as LAC. It follows that given the technology, a firm trying to
mini mise its average cost over time must choose a plant which
gives minimum LAC where SAC = SMC = LAC = LMC. This size of
plant assures most efficient utilisation of the resource. Any change
in output level, i.e., increase or decrease, will make the firm enter
the area of in optimality.
ECONOMIES AND DISECONOMIES OF SCALE
Scale of enterprise or size of plant means the amount of investment
in relatively fixed factors of production (plant and fixed equipment).
Costs of production are generally lower in larger plants than in the
smaller ones. This is so because there are a number of economies
of large-scale production.
Economies of Scale
Marshall classified the economies of large-scale production into two
types:
1. ExternalEconomies
2. Internal Economies
External Economies are those, which are available to all the
firms in an industry, for example, the construction of a railway line
in a certain region, which would reduce transport cost for all the
firms, the discovery of a new machine, which can be purchased by
all the firms, the emergence of repair industries, rise of industries
utilising by-products, and the establishment of special technical
schools for training skilled labour and research institutes, etc. These
economies arise from the expansion in the size of an industry
involving an increase in the number and size of the firms engaged in
it.
Internal Ecnomies are the economies, which are available to
a particular firm and give it an advantage over other firms engaged
in the industry. Internal economies arise from the expansion of the
size of a particular firm. From the managerial point of view, internal
economies are more important as they can be affected by
managerial decisions of an individual firm to change its size or
scale.
Types of Internal Economies
There are various types of internal economies such as labour,
technical, managerial, marketing and so on. We will discuss the
types of internal economies in detail in the following section:
Labour Economies: If an firm decides to expand its scale of
output, it will be possible for it to reduce the labour costs per
unit by practising division of labour. Economies of division of
labour arise due to increase in the skill of workers, and the
saving of time involved in changing from one operation to the
other. Again, in many cases, a large firm may find it
economical to have a number of operations performed
mechanically rather than manuaily. These economies will be
of great use in firms where the product is complex and the
manufacturing processes can be sub-divided.
Technical Economies: These are economies derived from
the use of subsize machines and such scientific processes like
those which can be carried out in large production units. A
small establishment cannot afford to use such machines and
processes, because their use would bring a saving only when
they are used intensively. On the other hand, their use will be
quite uneconomical if they were to lie idle over a considerable
part of the time. For example, a large electroplating plant
costs a great deal to keep it in operation. Therefore, the cost
per unit will be low only if the output is large. Similarly, a
machine that facilitates the pressing out a side of a motorcar
will take a week or more to be put ready for operation to
produce a particular design. The greater the output of cars of
this particular designs the lower the cost per unit of getting
the machine ready for operation. Similarly, if a dye is made to
produce a particular model of cars, the cost of dye per unit of
cars will depend upon the output of the cars. Very often large
firms may find it economical to produce or manufacture parts
and components for their products rather than buy them from
outside sources. For example, Hind Cycles, unlike small
mariufacturers, produced parts and components themselves.
Moreover, large firms may find it profitable to utilise their by-
products and waste products. For example, Tata use the
smoke from their furnaces to manufacture coal tar,
naphthalene, etc. A small firm's output of smoke would not be
large enough to justifY setting up the .equipment necessary to
do so.
Managerial Economies: When the size of the fern increases,
the efficiency of the management usually increases because
there can be greater specialisationin managerial staff. In a
large firm, experts can be appointed to look after the various
sections or divisions of the business, such as purchasing,
sales, production, financing, personnel, etc. But a small firm
cannot provide full-time employm·entto these experts
naturally, the various aspects of the business have to be
looked after by few people only who may not necessarily be
experts. Moreover, a large firm can afford to set up data
processing and mechanised accounting, etc., whereas small
firms cannot afford to do so.
Marketing Economies: A large firm can secure economies in
its purchasing and sales. It can purchase its requirements in
bulk and thereby get better terms. It usually receives prompt
deliveries, careful attention and special facilities from its
suppliers. This is sometimes due to the fact that a large buyer
can exert more pressure·, at times compulsive in nature, for
specially favoured treatment. It can also get concessions from
transport agencies. Moreover, it can appoint expert buyers and
expert salesmen. Finally, a large firm can spread its advertising
cost over bigger output because advertising costs do not rise in
proportion to a rise in sales.
Economies of Vertical integration: A large firm may decide
to have vertical integration by combining a number of stages of
production. Thisintegration has the advantage that the flow of
goods through various stages in production processes is more
readily controlled. Steady supplies of raw materials, on the one
hand, and steady outlets for these raw materials, on the other,
make production planning more certain and less subject to
erratic and unpredictable changes. Vertical integration may also
facilitate cost control, as most of the costs become controllable
costs for the enterprise. Transport' costs may also be reduced
by planning transportation in such a way that cross hauling is
reduced to the minimum.
Financial Economies: A large firm can offer better security and
is, therefore, in a position to secure better and easier credit
facilities both from its suppliers and its bankers. Due to a better
image, it enjoys easier access to the capital market.
Economies of Risk-spreading: The larger the size of the
business, the greater is the scope for spreading of risks through
diversification. Diversification is possible.on two lines as follows:
o Diversification of Output: If there are many products,
the loss in the sale of one product may be covered by
the profits from others. By diversification, the firm
avoids what may be called putting all eggs in the same
basket. For example, Vickers Ltd., make aircrafts, ships,
armaments, food-processing plant, rubber, plastics,
paints, instruments arid a wide range of other products.
Many of the larger firms have taken to diversification.
ITC diversified to include marine products and hotel
business in its operations.
o Diversification of Markets: The larger producer is
glenerally in a position to sell his goods in many
different and even far-off places. By depending upon
one market, he runs the risk of heavy loss if sales in
that market decline for one reason or the other.
Sargant Floren'ce and Economies of Scale
Sargant Florence has attributed the economies of scale the three
principles, which are in operation in a large-sized business, namely,
the principle of bulk transactions, the principle of massed reserves,
and the principle of multiples.
Principle of Bulk Transactions: This principle implies that
the cost of dealing with a large batch is often no greater than
the cost of dealing with a small batch, for example,' the cost of
placing an order, large or small; availability of discounts on
bulk orders, or annual purchase contracts; economies in the
use or'large containers such as tanks or trucks of special
design, for a container holding, say, twice as much as the other
one, does not cost double the amount.
• Principle of Massed Reserves: A large firm has a number of
departments or sections and its overall demand for services,
say, transport services, is likely to be fairly large. But it is
unlikely that all departments will make heavy demands of the
particular service at the saine time. Thus the firm can afford to
have its own transport fleet and fully utilise it and thereby
ultimately reduce its costs. The larger the firm, the greater are
the advantages.
Principle of Multiples: This principle was first raised by
Babbage in 1832 and has also been referred to as 'Balancing of
Processes'. The principle can be better explained through an
example. Suppose a manufacturing, operation involves three
processes, first in which a machine (:an make 30 units a week;
second in which an automatic machine can make 1,000 units
per week; and a third in which a semi-automatic machine can
make 400 units per week. Unles~ the output of the plant is
some common multiple of 30,1,000 anti 400, one or more of the
processes will have unutilised capacity. Their LCM is 6,000 and,
therefore, to best utilise all the machines the plant size must be
of at least 6,000 units or any of its multiples.
Economies of Scale and Empirical Evidence
According to the surveys conducted by the Pre-investment Survey
Group (FAG) and later on by the NCAER, it has been pf()Ved that in
paper industry, profitability decreases with lower scaly of operations
and bigger plants beneht from economies of scale. The report of the
Pre-investment Survey Group (FAG) reveals that the manufacturing
cost of writing and printing paper would fall from Rs. 1,489 in a 100-
tonne per day plant to Rs. 1,238 in a 200-tonne per day plant and
further to Rs. 1,104 in a 300-tonne per day plant. The following
Table 3.2 further shows the capital cost of raw materials and
operating cost per tonne of paper according to the size of the unit,
as estimated by the NCAER.

Another study of cement industry by the Economic and
Scientific Research undation-shows that the per unit of capacity
capital investment of a 3,000 tonne per' day (TPD) capacity cement
plant islower than the plants of 50 TPD size. Thus a single cement
plant producing 3,200 TPD requires 46 per cent less capital
investment than 8 plants of 400 TPD productions would. As regards
cost of production, a 800 TPD plant has a 15 per cent cost
advantage over a 400 TPD plant. The difference between the cost of
production of a tonne of cement by a 3,000 TPD plant and of a50
TPD plant is as high as Rs. 100 per tonne. In fact, there has been a
perceptible increase in the size of cement plants in India. For
example, the 600 tonnes per day capacity cement plants during the
early 1960s gave way with their size going up to 1,200 tonnes per
day. The latest preference is for 3,200 tonnes per day capacity
plants. A significant policy implication of economics of scale is that
in order to earn a reasonable return and at the same time ensure a
fair deal to the consumers, the industry should go in for larger
plants and expand the existing plants to .the optimum level.
The 6/10 Rule
A useful rule that seeks to measure economies of scale is the 6/1 0
rule. According to this rule, if we want to double the volume of a
container, the material needed to make it will have to be increased
by 6/10, i.e., 60 per cent. A proofofthe'6/l0 rule is easy and can be
given here with its advantage. Let us begin with the volume of a
container and the material required to make it. Suppose the
container is of the shape of a Gube with its side. The volume of the
container then is:
Vo = ao x ao x ao = ao3
Now, to find out the area of material needed, we know that the
container will have six equal square faces, each of area an 2 so, the
area of total material needed IS:
Mo = 6 x ao2 = 6ao2
Suppose now, that the container's dimension increases from an
to all the volume of the container will then increase to al3 and the
area of t~e material needed will increase to 6a12.
Thus, for two containers of dimensions an and al the ratio of the
areas of material needed will be:
M1
=
6a1/2
=
a1/2
M0 6a0/2 a0
The corresponding ratio of the volumes will be:
V1
=
a1/3
=
a1/3
V0 a0/3 a0
From the above, it follows that:
M1
=
a1/2
=
a1/3.2/3=
V 1 2/3
M0 a0/2 a0 V0
Now, if we double the volume, i.e., if
V1 = 2V0 orV1
=2V0
Then,
M1=
V1 2/3= (20) 2/3 = 1.59
M0 V0
M1 = 1.59 M0
In other words, doubling the volume requires 59 per cent
increase in material. This is rouJded off as 60 per cent, which is the
same as 6/1O. It may be added that, if in place of a cubical container, we had
taken the example of a spherical or a rectangular or a cylindricai or for that matter a
conical container, we would have aijived at the same relationship, viz.,
M1
=V12/3
M0 V0
The 6/10 rule is of great practical significance. Its significance
can well be realised if we visualise, for example, blast furnaces as
boxes containing the ingredients needed to produce iron, or tankers
as large boxes containing oil.
Minimum Economic Capacity (MEC) Scheme
Small size firms do not enjoy economies of scale. As such, in
pursuance of government's policy to encourage minimum efficient
capacity in industrial und~i1akings, the Government of India has
introduced' MEC Scheme to petrochemical industries, for example,
Naphtha / Gas Cracker (3 to 4 lakhs tonnes), Bopp Film (56,000
tonnes), Polyster Film (5,000 tonnes), Polyster Filament Yam
(25,000 tonnes), Acrylic Fibre (20,000 tonnes), MEG (One lakh
tonnes), PTA (2lakh tonnes), etc.
World Sdale
With re·cent trends towards globalisation of industries in India, the
concept of "World Scale" has emerged. The term 'World Scale' refers
to that scale or size of the enterprise, which is large enough to
enable the firm to reap various large-scale economies so as to
compete successfully on the world basis with global rivals. Thus
Reliance Industries Limited has recently announced to build a world
scale polyester facility at Hnzira and a cracker project with capacity
expanding from earlier 40,000 tonnes·to the world scale of 7,50,000
tonnes per annum.
Diseconomies of Scale
Economies of increasing size do not continue indefinitely. After a
certain point, any further expansion of the size leads to
diseconomies of scale. For example, after the division of labour has
reached its most efficient point, further increase in the number of
workers will lead to a duplication of workers. There will be too many
workers per machine for really efficient production. Moreover, the
problem of co-ordination of different processes may become
difficult. There may be divergence of views concerning policy
problems among specialists in management
and reconciliation may be difficult to arrive. Decision-making
process becomes slow resulting in missed opportunities. There may
be too much of formality, too many individuals between the
managers and workers, and supervision may' become difficult. The
management problems thus get out of hand with consequent
adverse effects on managerial efficiency.
The limit of scale economics is also often explained in terms of
the possible loss of control and consequent inefficiency. With the
growth in the size of the firm, the control by those at the top
becomes weaker. Adding one more hierarchical level removes the
superior further away from the subordinates. Again, as the firm
expands, the incidence of wrong judgements increases and errors
in judgement become costly.
Last be not the least, is the limitation where the larger the
plant, the larger is the attendant risks of loss from technological
changes as technologies are changing fast in modern times.
Diseconomies of Scale and Empirical Evidence
Large petro-chemical plants achieve economies in both full usage
and in utilisation of a wider range ofby-products, which would
otherwise, be wasted. But above 5,00,000 tonnes, diseconomies of
scale sets in because of the following occurrences:
The plant becomes so large that on-site fabrication of some
parts is required which is much more expensive;
Starting up costs are much higher, more capital is tied up and
delays in commissioning can be extremely expensive; and
The technical limit to compressor size has been reached.
There is, however, no substantial evidence of diseconomies of
large-scale production. In the final analysis, however, a significant
test of efficiency is survival. If small firms tend to disappear and
large ones survive, as in the automobile industry, we must
conclude that small firms are relatively inefficient. If small firms
survive and large ones tend to disappear as in the textile industry,
then large firms are relatively inefficient. In reality, we find that in
most industries, firms of very different sizes tend to survive.
Hence, it can be concluded that usually there is no significant
advantage or disadvantage to size over a very wide range of
outputs. It may mean, of course, that the businessman in his
planning decisions determines that beyond a certain size, plants do
have higher costs and, therefore, does not build them.
Somewhat surprisingly, some Indian entrepreneurs have been
perceptive enough to attempt to derive the advantages of both
large and small-scale enterprises. In the late sixties, the Jay
Engineering Co. Ltd. evolved a strategy of blending large units with
small enterprises to obtain the best of both worlds. It manufactures
its Usha fans in three different plants (Calcutta, Hyderabad and
Agra), with each plant' manu facturing the same or a similar range
of products. Each unit is autonomous and is free to take operational
decisions except in highly strategic areas. Within each unit, the
work-force is kept small to carry out vital operations such as
forgoing, blanking, notching and final assembly. The rest of the
work is sub-contracted to neighbouring small-scale units, which
over a period or time have become almost integral parts of each
plant. Loans for the purchase of machinery are also advanced and
technical know-how and sometimes-eve training is provided to
these ancillary units.
Payments are made promptly. The whole system operates like
families within a larger family. Managers in the US, who are always
quick in innovating, have also begun adopting this blended system
during the past few years. General Motors encourages the creation
ofa cluster of independent enterprises in an area, with adequate
autonomy granted to the company's area chief to encourage their
growth and developm.ent. Consequently, though a giant in the
automobile industry, General Motors enjoys a large number of the
privileges that acerue to small units and also reaps the special
benefits accruing to large business firms.
Economies of Scope
This concept is of recent development and is different from the
concept of economies of scale. Here, the cost efficiency in
production process is brought out by variety rather than volume,
that is, the cost advantages follow from variety of output, for
example, product diversification within the given scale of plant as
against increase in volume of production or scale 6f output. A firm
can add new and newer products if the size of plant and type of
technology make it possible. Here, the firm will enjoy scope-
economies instead of scale economies.
COST CONTROL AND COST REDUCTION
Cost Control
The long-run prosperity of a firm depends upon its ability to eam
sustaid profits. Profit depends upon the difference between the
selling price and the cost of production. Very often, the selling price
is not within the control of a firm but many costs are under its
control. The firm should therefore aim at doing whatever is done at
the minimum cost. In fact, cost control is ail essential element for
the successful operation of a business, Cost control by management
means a search for better and more economical ways of completing
each operation. In effect, cost control would mean a reduction in the
percentage of costs and, in turn, an increase in the percentage of
profits. Naturally, cost control is and will continue to be of perpetual
concern to the industry.
Cost control has two aspects' such as a reduction in specific
expenses and a more efficient use of every rupee spent. For
example, if sales can be increased with the same amount of
expenditure, say, on advertising and saTesmen, the cost as a
percentage of sales is cut down. In practice, cost control will
ultimately be achieved by looking into both these aspects and it is
impossible to assess the contribution, which each has made to the
overall savings. Potential savings in individual businesses will,
however, vary between wide extremes depending upon the levels of
efficiency already achieved before cost controls are introduced.
It is useful to bear in mind the following rules covering cost
control activities:
It is easier to keep costs down than it is to bring costs down.
The amount of effort put into cost control tends to increase
when business is bad and decrease when business is good.
There is more profit in cost control when business is. good than
when I business is bad. Therefore, one should not be slack
when conditions are good.
Cost control helps a firm to improve its profitability and
competitiveness. Profits may be drastically reduced despite a large
and increasing sales volume in the absence of cost control. A big
sales volume does not necessarily mean a big profit. On the other
hand, it may create a false sense of prosperity while in reality;
increasing costs are eating up profits. Profit is in danger-when good
merchantdising and cost control do not go hand in hand. Cost
control may also help a firm in reducing its costs and thus reduce its
prices. A reduction in prices of a firm would lead to an increase in its
competitiveness. The aspect is of particular relevance to Indian
conditions because of high costs, India is being priced out of the
world markets.
Tools of Cost Control
Following ar.e the tools that are used for the cost control:
Standard Costs and Budgets: The technique of standard,
costing has been developed to establish standards of performance
for producing gvuus and services. These standards serve "as a goal
for the attainment and as basis of comparison with actual costs in
checking performance. The analysis of variance between actual and
standard costs will: (i) help fix the responsibility for non-standard
performance and (ii) focus attention on areas in which cost
improvement should be sought by pinpointing the source of loss and
inefficiency. The principle here is that or controlling by exception.
Instead of attempting to follow a mass of cost data, the attention of
those responsible for cost control is concentrated on significant
variances from the standard. If effective action is to be taken, the
cause and responsibility of a variance, as well as its amount, must
be established.
The prime objective of standard costs is to generate greater
cost consciousness and help in cost control by directing attention
to specific areas where action is needed. To those who are
immediately concerned, variances wou1d indicate whether any
action is required on their part. It must be noted that
Costs are controlled at the points where they are incurred and
at the time of occurrence of events, and
At the same time they may be uncontrolled at some points.
It is, therefore, necessary to understand the difference
between controllable and uncontrollable costs. The variances may
also be controllable and uncontrollable. For example, if the material
cost variance is due to rise in prices, it is not within the control of
the production manager. But if the variance is due to greater usage,
control action is certainly possible on his part. The higher
management can also deCide whether or not they should intervene
in the matter. Sometimes, variances may be so significant that a
complete reapRraisal of the standard costs themselves may be
needed.
For example, if the variances are always favourable, it may
point to the fact that the standards have not been properly fixed.
Standard costing can also provide the means for actual and
standard cost comparison by type of expense, by departments or
cost centres. Yields and spoilage can be compared with the
standard allowance for loss. Labour operations and overheads also
can be checked for efficiency. Flexible budgets constitute yet
another effective technique of cost control, especially control of
factory overheads. Flexible budgets, also known as variable
budgets; provide a basis for determining costs that are anticipated
at various levels of activity. It provides a flexible standard for
comparing the costs of an actual volume of activity with the cost
that should be or should have been. The variances can then be
analysed and necessary action can be taken in the matter. Table
3.3 gives a specimen flexible budget.
Table 3.3: Finishing Department, Modern Manufacturing Co.
Standard hours of direct labour35,000 40,000 45,000
Labour cost hour at Rs. 3 per Rs. 1,05,000 Rs. 1,20,000 Rs. 1,35,000 Other variable costs 17500 20.000 22,500 Semi-variable costs 9,250 10,000 10,250 Fixed costs 50,000 50,000 50,000 Total Rs.l,81,75Q Rs. 2,00,000 Rs.2,17,750
The scientific establishment of standards of performance
through standard costs and budgets has not only provided better
cost control but has led to cost reduction in a number of
companies. This has been the case especiilIIy in companies where
standards were tied to wage-incentive plans and improyement in
control is part of a general programme of better management. The
above table shows three budgets, one each for 35,000, 40,000 and
'45,000 standard hours of work. In practice, one may come across
50 or more cost items in the budget and not just four as shown in
the table.
Ratio Analysis
RatIo is a statistical yardstick that provides a measure of the
relationship betweeri two figures. This relationship may be
expressed as a rate (costs per rupee of sales), as a per cent (cost of
sales as a percentage of sales), or as a quotient (sales as a certain
number of time the inventory). Ratios are commonly used in the
analysis of operations because the use of absolute figures might be
misleading. Ratios provide standards of comparison for appraising
the performance of a business firm. They can be used for cost
control purposes in two ways:
A businessman may compare his firm's ratios for the period
under scrutiny with similar ratios of the previous periods. Such
a comparison would help him identify areas that need his
attention.
• The businessman can compare his ratios with the standard
ratios in his jndustry. Standard ratios are averages of the
results achieved by thousands, of firms in the same line of
business.
If these comparisons reveal any significant differences,
thtYmanagement call analyse the reasons for these differences and
can take appropriate action to remove' the causeS responsible for
increase in costs. Some of the most commonly used ratios for cost
corrtparisons are given below:
• Not profits/sales.
Gross profits/sales.
Net profits/total assets.
Sales/totaLassets.
• Production costs/costs of sales.
Selling Costs/costs of sales.
Admiriistration costs/costs of sales.
Sahes/iriventory or inventory turnover.
Material costs/prod1, Jction costs.
Labour costs/production
costs.
Overhead/prqduction costs.
Value Analysis: Value analysis is an approach to cost saving
that deals with product design. Here, before making or buying any
equipment or materials, a study is made of the purpose to which
these things serve. Would other lower-cost designs work as well?
Could another less costly item fill the need? Will less expensive
material, do the job? Can scrap be reduced by changing the design
or the type of raw materiaJ? Are the seller's costs as low as they
ought to be? Suppliers of alternative materIals can provide the
ample data to make the appropriate choice. Of course, absorbing
and reviewing the data will need some time. Thus the objective of
value analysis is the identification of such costs in a product that do
not in any manner contribute to its specifications or functional
value. Hence, value analysis is the process of reducing the cost of
the prescribed function without sacrificing the required standard of
performance. The emphasis is, first, on identificatiqn of the required
function and, secondly, on determination of the best way to perform
it at a lower cost. This novel method of cost reduction is not yet
seriously exploited, in our country. Value analysis is a
supplementary device in addition to the con~entional cost reduction
methods.
Value analysis is closely related to value engineering, though
they are not identical. Value analysis refers to the work that
purchasing department does in-this direction whereas value
engineering usually refers to what engineers are doing in this area.
The purchasing department raises questions and consults the
engineering department and even the vendor company's
department. Value analysis thus requires wholehearted co-operation
of not only the firm's expertise in design, purchase, production and
costing but also that of the vendor and other company expertise, if
necessary. Some examples of savings through value analysis are
given below:
Discarding tailored products where standard components can
do.
Dispensing with facilities not specified or not required by the
customer, for example, doing away with headphone in a radio
set.
Use ofnewly-deyeloped, better and cheaper materials in place
of traditional materials.
Taking the specific case of TV industry, there are various
components of cost, which can be questioned. The various items are
as under:
Whether to have vertical holding chassis or the chassis should
be tied down horizontally. In case, chassis is held vertically,
additional expenditure in terms of holding clamps is required.
Whether to have plastic cabinet or wooden cabinet.
Whether to have two speakers or one speaker.
Whether to have sliding switches or stationary switches.
Whether to have PVC back cover or wooden back cover.
Whether to have costly knobs or cheaper knobs.
Whether to have moulded mask or extruded plask.
Whether to have Electronic Tuner or Turret Tuner.
Whether to have digital operating unit or noble operating unit.
Cost control is applicable only to such costs, which can be
altered by the management on their own initiative. It may be noted
in this context that, by and large, non-controllable costs exceed far
more than controllable ones thereby restricting the scope of profit
impfoyement through cost, control. Of course, attempts may be
made to convert an uncontrollable cost into a controllable one.
Vertical combinations to secure control over sources of supply
provide an example. So also instead of buying a component, a firm
may decide to make the conversion possible.
AREAS OF COST CONTROL
Folloviing are the areas where the cost can be controlled:
1. Materials
There area number of ways that help in reducing the cost
ofmatenals. Ifbuying is done properly, a firm avails itself of quantity
discounts. While buying from a particular source, in addition to the
cost of materials, consideration should be given to freight charges.
In some cases, lower prices of materials may be offset by higher
freiight to the firm's godown. Whiie buying, one may attempt to buy
from the cheapbt source by inviting bids. At times, it may be
possible to have more economical substitutes for raw materials that
the firm is using. Many a times, improvell1ent in product design
may lead to reduction in material usage. It is desirable to
concentrate attention on the areas where saving potential is the
highest.
Another area, which needs examination in this respect, is
whether to make or buy components from outside source. Very
often firm may find it advantageous to manufacture certain parts
and components in one's own factory rather than buying them. Yet
in many cases there are specific advantages in purchasing spares
and components from outside because suppliers may deliver goods
at low cost with high quality. For example, Ford and Chrysler of the
US Auto Industry purchase their components from outside source.
But General Motors could not do so because the firm has its own
departments for handling the process of production. This type of
firm is referred as vertically integrated firm where it owns the
various aspects of making seIling and delivering a product Hind
Cycles, which has now been taken over by the Government,
manufactures all its components. But manufacturers of Hero and
Avon Cycles purchased most of their components from outside
source and successfully competed with Hind Cycles.
Continuous Research and Development (R & D) may also lead
to a reduction in raw material costs. For example, Asian Paints
made high savings in costs of raw materials by its phenomenal
success on Research and Development front, by manufacturing
synthetic resins for captive consumption. Total materials consumed
as a ratio of value of production fell from 67.66 per cent in 1973 to
60-67 per cent in 1977. General Motors have reduced the weight of
their cars to make them more fuel-efficient. Better utilisation of
materials' may also save the cost of materials by avoiding wastes in
storing, handling and processing. Some of the factors, responsible
for excessive wastage of materials are: lack of laid down
requirements for raw materials, bad process planning, rejects due to
faulty materials or poor workmanship, lack of proper tools, jigs and
fixtures, poor quality of materials, loose packing, careless and
negligent handling and careless storage.
Exploration of the possibilities of the use of standardised parts
and components and the utilisation of waste and by-products, may
also lead to a significant reduction in the cost of materials.
Inventory control is yet another area for reducing materials
cost. Thro inventory control, it is possible to maintain the
investment in inventories at lowest amount consistent with the
production and the sales requirements of firm. The cost of
carrying inventories ranges from 15 to 20 per cent per annum
account of interest on capital, insurance, storage and handling
charges, spilla breakage, physical deterioration, pilferage and
obsolescence. Again 50 per cent the gross working capital may be
locked up in inventories.
Some important ways of reducing inventories are:
Improved production planning.
Having dependable sources of supplies, which can ensure
prompt deliver of materials at short notice.
Elimination of slow-moving stocks and dropping of obsolete
items.
Improved flow of part and materials leading to increased
machine
utilisation and shorter manufacturing cycles.
Packaging constitutes a significant proportion of raw
materials (9 to 24 per cent) and of the total manufacturing
expenses (7 to 22 per cent). Firm should mal attempts to reduce
the packaging costs to the minimum. For example, instead
discarding containers that the materials come in it may be used for
shipping tl goods and thus, the packaging cost can be saved. The
manufacturing firms such; cars and motor bikes may request its
customers to return the containers in whic are goods were sent so
that they could be used in future. This is because packin of such
goods as well as the materials used for packing is very expensive.
2. Labour
Reduction in wages for reducing labour costs is out of question. On
the other hand, wages might have to be increased to provide
incentives to workers. Yet there is good scope for reduction in the
wage cost per unit. A reduction in labour costs is possible by proper
selection and training, improvement in productivity and by
automation, where possible. A study by cn (Confederation of Indian
Industry) showed that Hero Cycles improved their productivity per
employee by 6.4 per cent. 'Purolators' were able to increase their
productivity by 100 per cent. Work· study might result in a lot of
savings by reducing overtime and idle time and providing better
workloads. Labour productivity might increase if frequent change of
tools is avoided. Improvement in working conditions may reduce
absenteeism and thus reduce costs per unit. Scrutiny of overtime
may reveal substantial scope for savings.
All efforts must be made to redllce wastage of human effort.
Wastage of human effort may be due to lack of co-ordination among
various departments by having more workers than necessary,
·under-utilisation of existing manpower, shortage of materials,
improper scheduling, absenteeism, poor methods and poor morale.
For example, Metal Box adopted a Voluntary Severance Scheme in
197576 to reduce their work force by 950 workers after they faced a
huge operating loss ofRs. 2.4 crores. General Motors eliminated
14,000 white-collar jobs through attrition to reduce cost. Japan's big
5 steel producers announced substantial retrenchment programmes
and workers co-operated with the management. Attempts must be
made to secure co-operation of employees in cost reduction by
inviting suggestions from them. These suggestions should be
carefully examined and implemented if found satisfactory.
Hindustan Lever has a suggestion box scheme and employees who
come out with good suggestions receive awards. These suggestions
may either lead to savings or improve safety and work convenJence.
The basic idea is to motivate workers and make them perceive
working in the firm as a participative endeavour.
3. Overheads
Factory overheads may be reduced by proper selection of
equipment, effective utilisation of space and .equipment, proper
maintenance of equipment and reduction in power cost, lighting
cost, etc. For example, fluorescent lighting can reduce lighting cost.
Faulty designs may lead to excessive use of materials or multiplicity
of components, waste of steam, electricity, gas, lubricants, etc. A
British team invited by the Government of India to report on
standards of fuel efficiency in Indian industry found that fuel
wastages might be as high as an average of 25 per cent. Keeping
them in check even in the face of increasing sales may reduce
overhead costs per unit. For example, Metal Box maintained their
fixed costs in 1976-77 even when there was an increase in sales of
over 18 per cent.
Taking advantage of truck or wagonloads may reduce
transportation cost. Careful planning of movements may also save
transportation cost. Another point to be examined is whether it
would be economical to use one's own transport or hire a transport.
For reasons of economy, many transport companies hire trucks
rather than owning them. This is because purchase and
maintemince of trucks can be more expensive. By chartering
vehicles the problems of maintenance is left to the owner who in
turn Cuts cost for the firm. Thus by keeping a smaller work force on
rolls and by introducing a contract rate linked to a safe delivery
schedule it is possible to ensure speedy point-to-point delivery of
goods. Many firms now prefer to use private taxis rather than have
their own staff cars.
Reduction of wastes in general can also reduce manufacturing
costs considerably. Of course, a certain amount of waste and
spoilage is unavoidable because employees do make mistakes,
machines do get out of order and sometimes raw materials are
faulty. However, attempts can be made to reduce these mistakes
and faulty handling to the minimum. The normal figure for the waste
and spoilage depends upon the complexity of the product, the age
of the manufacturing plant, and the skill and experience of the
workers. Once normal wastage is found out, production reports must
be watched carefully to find out whether the wastages are
excessive. Wastes can be reduced considerably by educating
operators in the causes and cures of the wastes. Bad debt losses
can be reduced considerably by selecting customers carefully, and
keeping an eye on the receivables. Concentrating on areas and
media can reduce advertising costs, which give the best results.
Selling costs can be controlled by improving the supervision and
training of salesmen, rearrangement of sales territories, replanting
salesmen's routes and calls and redirecting of the sales efforts, to
achieve a more economic product mix. It may be possible to save
selling costs by the use of warehouses, making bulk shipments to
the warehouses and giving faster deliveries to the customers.
Centralisation, reduction, clerical and accounting work may also lead
to cost savings. A look at the telephone bills and the communication
cost in general may also reveal areas for substantial savings. For
example a telegram may be sent in place of a trunk call.
(a) Cost Reduction
The Institute of Cost and Works Accounts of London has defined cost
reduction as "the achievement of real and permanent reductions in
the unit costs of goods manufactured or services rendered without
impairing their suitability for the use intended". Thus, cost reduction
is confined to savings in the cost of manufacture, administration,
distribution and selling by eliminating wasteful and unnecessary
elements from the product design and from the techniques and
practices carried out in coilOection with cost reduction?
(b) Cost Contro/and Cost Reduction
According to the Institute of Cost and Works Accounts, London,
"cost control, as generally practised, lacks the dynamic approach to
many factors affecting costs, which determine the need of cost
reduction." For example, under cost control, the tendency is to
accept standards once they are fixed and leave them unchallenged
over a period. In cost reduction, on the other hand, standards must
be constantly challenged for improvement. And there is no phase of
business, which is exempted from the cost reduction. Products,
processes, procedures and personnel are subjected to continuous
scrutiny to see where and how they can be reduced in cost.
To achieve success in cost reduction, the management must
be convinced of the need for cost reduction. The formulation of a
detailed and co-ordinated plan of cost reduction demands a
systematic approach to the problem. The first step would be the
institution of a Cost Reduction Committee consisting of all the
departmental heads to locate the areas of potential savings and to
determine the priorities. The Committee should review progress and
assign responsibilities to appropriate personnel. Every business
operation should be approached in the belief that it is a potential
source of economy and may benefit from a completely new
appraisal. Often, it may be possible to dispense entirely with
routines, which, by tradition, have come to be regarded as a
permanent feature of concern. Cost reduction is just as much
concerned with the stoppage of unnecessary activity as with the
curtailing of expenditure. It is imperative that the cost of
administering any scheme of cost reduction must be kept within
reasonable limits. What is reasonable must be determined in all
cases from the relationship between the expenditure and the
savings, which result from it.
Essentials for the Success of a Cost Reduction Programme
Following are the some of the points that firms should take care in
order to achieve success in the cost reduction programme:
Every individual within the firm should recognise· his
responsibility. The co-operation of every individual requires a careful
dissemination of the objectives and interest of the employees in the
achievement of the firm's goals.
Employee resistance to change should be minimised by
disseminating complete information about the proposed
changes and convincing the emplcyees that the changes are
concerned with the problems faced by the firm and that they
would ultimately benefit.
Efforts should be concentrated in the areas where the savings
are likely to be the maximum.
Cost reduction efforts should be continuously maintained.
There should be periodic meetings with the employees to
review the progress made towards cost reduction.
(c) Factors Hampering Cost Control in India
The cost of raw material and other intermediate products is
generally high. In many cases: the cost of raw materials is
substantially higher than their international prices, which makes it
difficult for the Indian firms to compete in foreign markets. The
sharp rise in oil prices in recent years also gave a severe push to the
cost of raw materials with petrochemical base. Shortages of raw
materials are a usual phenomenon. With a view to insuring against
these shortages, manufacturers keep larger inventories, which
result in increase in their costs. This occurs especially in case of
imported raw materials. Wages are always being linked to cost of
living. There are wage boards for almost every industry and
management has little control on wage rates.
Overheads are also higher in India due to the following reasons:
The size of the plant is very often uneconomic due to the
Government's desire to prevent concentration of economic
power. However, there is now a marked change in the policy.
In 1986, the Government announced that 65 industries would
be started with minimum economic capacity so as to 'make
India's products competitive. This process got a boost after the
new Industrial Policy was announced in July 1991.
There is under-utilisation of capacities due to lack of raw
materials and power shortage. However a manufacturer can
exceed his capacity by improving the techniques of production
process. Even after making improvements, a manufacturer
lacks the way to completely minimise the possibilities of
increase in the overheads.
Machinery and equipment obtained under tied credits usually
cost 30 to 40 per cent more than what it wouid cost if
purchased in the open market.
There are delays in the issue of licences and by the time
licences are issued, cost of equipment goes up. The number of
industries subject to licensing has now been drastically
reduced.
Increase in administered prices for many items crucial to the
industrial production by the Government from time to time
also pushes up costs.
Finally, there is what lis called by businessmen as 'unseen
overheads' in the nature of demands for illegitl gratification by
various Government officials at different administrative levels.
There are indirect taxes, which also tend to raise the overall
costs of production in India. Excise duties and saies taxes also
heighten the impact of indirect taxes on the cost of production.
India is perhaps the only country where basic raw materials carry
heavy excise duties. According to an estimate by Mr. S. Moolgaokar,
Chairman, TELCO, as much as Rs. 25 crores of working capital is
locked up in inventories and work-in-progress with TELCO and its
suppliers solely due to the present tax structure.
Until recent times the Indian industrialists operated in a
sheltered domestic market. They were protected against foreign
competition by import controls and against domestic competition
due to industrial licensing. So long as this sellers' market prevailed
competition among sellers was absent and there was no compelling
reason for the industrialists to pay any attention to cost reduction.
Cost consciousness was thus by and large absent in India. The price
fixation for products under price control ensured that the rise in
costs was fully reflected in the prices. This made it possible for the
industrialists to pass on any increase in costs to the consumers.
However, now with the advent of recession tendencies, and
liberalisation in licensing policies, the Indian industrialist is
compelled to pay greater attention to cost reduction and cost
control.
APPENDIX - I
Calculation of Variances
The difference between the standard cost and the comparable
actual, cost for the same element and for the same period is known
as cost variance. The total of the variances consequently represents
the difference between the actual profits and the standard profits,
i.e., the profits that ought to have been made. The variances are
said to be favourable or credit Variances when the actual
performance exceeds the standard performance or the actual costs
are lower than the standard costs. On the other hand, the variances
are unfavourableor debit variances when the actual, performance
falls short of the standard performance or the actual costs exceed
the standard costs. All variances must state the direction of the
variance as well as the amoUnt. Calculation of cost variances is an
important feature of standard costing. The formulae for calculating
the various variances are given below:
Material Cost Variance
(Actual Quantity x Actual Price) - (Standard Quanity x Standard
Price)
or, (AQ x AP) - (SQ x SP)
Material Price Variance
(Actual Price - Standard Price) x Actual Quantity
or, (AP - SP) x AQ
Material Usage or Quantity Variance
(Actual Quantity - Standard Quantity) x Standard Price
or, (AQ - SQ) x SP
Material usage variance can be further sub-divided into (i) Mix
variance and (ii) Yield variance. When the process uses several
different materials that are supposed to be combined in a standard
proportion, mix variance shows the effeclofvariations from the
standard proportion. The formula for calculating the mix variance is:
(Actual Quantity - Standard Proportion) x Standard Price
Yield variance shows the loss due to the actual loss being more
or less than the standard loss. The formula for calculating the yield
variance is:
(Actual Loss - Standard Loss) x Average Standard Input Price
Labour CostVariance
(Actual Hours x Actual Rate)-(Standard Hours x Standard Rate)
or, (AH x AR) - (SH x SR)
Labour Rate (Price) Variance
(Actual Rate - Standard Rate) x Actual Number of Hours
or, (AR- SR) x AH
Overhead Efficiency Variance
The object is to test the efficiency achieved from the actual
production. The variance is thus, analogous in nature to the labour
efficiency variance. The formula for calculation of the variance is:
(Actual Hours - Standard Hours for Actual Production)
x Standard Overhead Rate
or, (AH - SH) x SOlt
Cost control ultimately depends on action, which is based on
variances. However, these actions can be taken only by people who
have the appropriate authority. It is, therefore, futile to present
variances to a person if those variances are related to matters,
which fall outside his guthority. Such variances are called
uncontrollable whereas those relating to matters within his
authority ilre termed as controllable variance.
APPENDIX II
Cost Control Drive in Coal India Limited (Cll)
CIL closed in 1984-85 with a provisionally estimated profit of Rs. 20
pro res after fully discharging its depreciation and loan repayment
obligations. The company had to initiate a series of stringent
measures to achieve the profit figure, the thrust being on controlling
costs. Four specific areas chosen include: salary and wages,
administration expenditure, stores and realisation of dues. In 1983-
84, the incidence of salary and wages being what it was, the cost of
manpower, per tonne of coal worked out to Rs. 97.04. In 1984-85,
the rise was contained at 88 paisa and the cost of manpower per
tonne came to Rs. 97.92.This was despite the fact that there was a
rise of 51 points in the consumer price index. And then factors
would have justifledan increase of Rs. 6.44 in the cost of manpower
per tonne of coal but it was contained at 88 paisa.
The CIL Chairman pointed out that a major effort was made to
ensure gainful redeployment of manpower through persuasion and
motivation and at times even by force:' Empowered teams of senior
executives were sent to interview people and persuade them to
accept jobs that would suit them. Local redeployment was insisted
upon although in some places non-availability of residential
accommodation caused a problem. Secondly, increase of manpower
was controlled very strictly. Instructions were issued to subsidiary
companies that no new appointment was to be made without
Director of Finance and the Chairman approving it. Thirdly, a drastic
reduction was made in overtime allowance and for achieving this
objective even threat of sacking had to be administered.
In the sphere of administration expenditure, the thrust was on
cutting down the expenses on account of travelling allowance.
However, cost control measures were most effective in the sphere
of stores management. The system of 'fortress checks', introduced
in 1984-85 resulted in straight saving of Rs. 30 crores. CIL's profit in
1984-85 would have been about Rs. 80 crores, ,if only there was an
appropriate system of pricing.
PRICE DISCOUNTS AND DIFFERENTIALS
Distributors' Discounts
Distributors' discounts are the price reductions that systematically
make the net price vary according to buyers' position in the chain of
distribution. They are called so because these discounts are given to
various distributors in the trade channel, for example, wholesale
factors, dealers and retailers. For the same reason, they are also
called as trade channel discounts. As these discoUnts create
differential prices for different customers on the basis of marketing
functions performed by them for example, whether they are
wholesalers or retailers, they are also called as functional discounts.
However, it must be pointed out that the special discounts may also
be given to persons other than distributors and not, associated with
distribution function. For example, special discounts may be given
to manufacturers who incorporate the product in their own product.
Tyres and tubes sold; to cycle manufactUrers for use in their
bicycles, is a typical example. Special prices may be charged to
members of the same industry; for example, one company may
exchange petroleum with another company at a special price.
Again, special prices may be quoted to Central and State
Governments and to the Universities; for example, Remington
typewriters, Godrej safes, etc., are sold at low prices to these
places.
Forms of Distributors Discounts
Distributors' discounts take different forms determined mainly by
the consent of all the business firms in an industry. Nevertheless, at
times firms may have to decide about the form in which discount is
to be offered. There are mainly three forms:
Different net prices for different distributor levels. Net prices
are rarely used for quoting differential prices to distributors.
Manufacturers give them to certaii1iliithorised dealers. The
simplicity of this method enables some savings in invoicing
and accounting.
A uniform list price modified by a structure of discounts, each
rate applicable to a different level of distributor, List prices
with discounts are more common. This method makes it easy
to deal with diverse trade channels. It also facilitates cyclical
'and seasonal adjustments in prices by merely varying the
discounts. This may also help in keeping actual prices a
secret, not only among distributors but also from competitors·
and customers secret, not only among distributors but also
from competitors and customers.
A single discount combined with different supplementary
discounts to different levels of distributors. For example, 5
per cent to regional distributors.
Thus, the chief advantage of the prices with discounts is
greater flexibility. Further, this method helps the manufacturers to
exercise greater control over the realised' margin of different
categories of distributors. But real control is achieved only when
such discounts are coupled with resale price maintenance. A
supplementary discount gives the manufacturers, a picture of the
entire trade channel structure. These discounts may be intended to
reflect distributors cost at' different stages and competition
between different kinds of distributors. The supplementary
discounts are very descriptive in nature while their accounting is
expensive. Distributors' discounts differ widely in industries. They
also differ among the various business firms within industry.
How to Determine Distributors' Discounts
The economic function of distributors' discounts is to induce
different categories of distributors to perform their respective
marketing functions. As such, to build up a discount structure on
sound economic lines, it is essential to know the services to be
performed by the distributors, distributors' operating costs, discount
structure of competitors, effects of discounts on distributor
population, cost of selling to different channels and opportunities
for market segmentation.
Services to be performed by the distributors at different
levels: The main objective of the manufacturer is to get the
distributor function performed most econoiIlically and
effectively. For this purpose, he may decide upon the various
types of services to be performed by the various types of
distributors. The larger is the number of services' to be
performed by the distributor concerned, the larger is the
discount allowed to him, and. vice versa. For example, a sewing
machine manufacturer might de£idethat the dealer will only
display the various models of the machine manufactured by the
firm and settle the terms of sale. The delivery and servicing of
the machines may be given to one distributor in the city.
Naturally, in such a cast the discount given to the dealer will be
lower than in the case where he has to stock the commodity
and provide after-sales services as well.
Distributors’ operating costs: Trade discounts should
naturally cover the operllting costs and the normal profits of the
distributors. In case of high margins, distributers would be
induced to make extra selling efforts. If margins do not cover
costs, the distributors concerned would not be interested in
pushing up the sale of the product. Sometimes distributors
belonging to the same category by name may be performing
widely diflcl'ing functions, Their operating cost is, therefore,
determined by the funel ions they perform, For example, if a
distributor is required to warehouse and ship the goods as and
when required by the actual users, he would require greater
discounts than a distributor who receives the consignments in
truckloads and merely reships them to the different actual
users without having to warehouse' them. Even when
distributors are pcrforming identical services, operating
costs'may differ among individual distrihutors depending upon
variations in their operating efficiency. In such cases, the
manufacturer has to determine as to whose costs will he try to
cover through trade discounts. There are two possible
alternatives: (I) the costs or the most efficient two-thirds of the
dealers plus normal profits, or (2) an estimate of his own cost of
performing the distribution function. This is very oncn used
when the manufacturer is already engaged in some sort or
distribution runction.
Competitor’s discount structure: The discounts granted by
competitors arc usel'lII guides in framing the structure of
discounts. Their relevance becomes still greater when it is
realised that distributors' discounts are given in order to scek
the dealers' sales assist~nce in a, competitive market. In quite
a good number of trades, discount rates are fixed by custom
and manufacturers have no option but to fall in line. In many
industries, the actual discounts' granted by rival sellers vary. In
such a case, the manufacturer has to decide whether he should
be guided by the higher or the lower discounts. In case the
product of the manufacturer is' at some disadvantage in
consumer acceptance, he may decide to allow 'larger margins
than those of his competitors. The success of the policy,
however, would depend upon the following conditions: (a)
whether this high margin of discount merely, compensates for
the low turnover and whether the distributor gets any real
economic in~entive? (b) Whether the discount margin will be
adequate to induce the distributor to push the product? (c) How
much influence does the distributor have in pushing a particular
brand over that of the competitor? (d) Whether the dealer has
scope for profitable market segmentation and personal price
discrimination? And (e) Whether competitor are likely to meet
the wider discount margi varying their own? Thus, in general,
the success of a particular dis scheme requires that the
consumers are considerably indifferent to bl have great
confidence in the distributor and the manufacturers' IT share is
so small that large competitors will not feel compelled to cI
their own wider margins. A related question is: should a lower
p~i, offered to dealers who handle a certain brand exclusively?
Naturall exclusive dealer in general will get a higher discount in
addition to price advantage arising from quantity discounts.
Effect of discounts on distributors' population: Very
often, I discounts may be allowed to encourage the entry of
new distribute push up the sales of a new product line.
Similarly, smaller discounts In allowed when the number of
distributors has to be restricted.
Costs of selling to different channels: There is asaving in
overheat selling to retailers as compared to consumers and· to
wholesalel compared to retailers and the regular system of
discounts has somethil do with this saving in overheads.
Opportunities for market segmentation: Trade channel
discounts C2 used to achieve profitable market segmentation.
In some industries market is divided into several fairly distinct
sub-markets, each havin own peculiar competitive and
demand characteristics. For example, il tyre market, the
following sub-markets may be distinguished:
o Original equipment market characterised by skill and
bargai strength ofthe buyers and by big cyclicaJ
fluctuations in demand.
o Individual consumer replacement. Market characterise by
unskilled buying, brand preferences, and cyclical stability.
o Commercial operators' replacement market characterised
by I buyers who are price-wise and quality-wise, for
example, munic transport undertakings.
o Government sale in market characterised by large orders,
foil bids and publication of successful bidders' price.
o Export market characterised by international competition.
Each one of these sub-markets .has different elasticity of,
demand. There! The need to charge different prices in each market
segment arises from difference in the elasticities of demand in
these submarkets. The disc (structure can be so devised as to
produce the relevant differential prices suitable for each market
segment. For example, in the case of original equipment market,
price has little influence on the total number of tyres purchased
because the price of the tyrespaid by automobile manufacturers
would form very small percentage of the wholesale price of the car,
say, less than 5 per cent. As such, no feasible reduction in tyre
prices would affect cat prices enough to increase perceptibly the
demand for cars and hence of tyres. Very often, while pricing a
product which is to be used as a component of the finished product
of another manufacturer, e.g., pricing of spark plugs or tyres, their
manufacturers may be influenced by such considerations as earning
prestige through associating the component with the finished
product, getting replacement business if the product is used as a
component with some well-known product, etc. Hence, while selling
the component product to the manufacturer of finished product;
lower prices and for that purpose higher discounts may be allowed.
In case of individual consumer replacement market, i.e., where
buyers are consumers demanding the product for replacement. The
level of price affects the timing of the demand within fairly regroups
limits set by the age of the product, say tyre. Here because of brand
preferences, buyers' responsiveness to price differences is lower
than in other markets where buyers' knowledge is greater.
Another pricing problem relating to individual consumer
replacement market arises because the manufacturer has to decide
whether to allow high discounts as to permit dealers to make-
individual concessions to customers. Here, a dealer can charge full
price from some customers who are averse to shopping and
bargaining but quite substantially lower prices to more careful and·
bargaining type of customers. Thus, allowing high discounts to
dealers provides them sufficient leeway to charge higher or lower
prices from their own customers according to their demand
elasticity. It is normally appropriate to allow the dealer large
discounts and thereby considerable latitude where the unit cost of
the article is high, where service concessions and trade-ins are
provided to the customers by way of veiled price concessions and
where the customer is not tied strictly to the dealer by continuity of
service or by customer relations.
A related pricing problem of the manufacturer is to decide
whether different distributor margins should be fixed for high-
quality high-price commodities, on the one hand, and low-quality
low-price products, on the other. The manufacturer has to consider
whether he' is to concentrate more on high quality or on low quality
products in view of their respective profitability. Market
segmentation achieved through differential distributors' discounts
enables building big plants' to reap economies of size.
Manufacturers have sometimes built bigger plants and to work them
to full capacity, they have taken up private label business
(manufacturing _ goods to order with private and exclusive brarids),
allowing greater discounts till their own brand becomes sufficiently
popular and its demand increases sufficiently to work the big plant
fully. If so, they can discontinue the private label business.
Distributors' demand elasticity higher than that of
consumers:
Distributors' demand for the competing brand of different
manufacturers is more elastic than the corresponding demand of
final consumers. The distributor is generally more capable of
judging price and quality than ultimate consumers who have
insufficient knowledge of the competing brands, and apprehend
that a low price may be synonymous with inferior quality. The
consumer finds it difficult to choose between different competing
brands, and he often allows himself to be guided by the retailers. It
may be safely asserted that even the smallest difference in price
may cause a dealer to switch over from one brand to another
whereas an even greater price change might not cause any
reaction on the ultimate consumers. It is, therefore, of decisive
importance to the manufacturers that they secure the goodwill of
the distributors. In. fact, the distributors' potential selling power is
great and the manufacturers should try to gain their promotional
support.
However, in the case of a few highly advertised branded
products, which occupy a firm's position in the minds of the
consumers, distributors have to be content with very small margins.
For example, the retailer's margin in a 5-kilo Dalda tin comes to 1.5
per cent only. It would be better for a manufacturer to adopt a
standard discount policy. With latitude in discount policy, there is
much danger of confusion, inequity, loss of goodwill and loss of
sales. It may also be noted that distributor discounts do not matter
much in industrial goods.
Quantity Discounts
Quantity discounts are price reductions related to the quantities
purchased. Quantity discounts may take several forms and may be
related to the size of the order being measured in terms of physical
units of a particular commodity. This is practicable where the
commodities are homogeneous or identical in nature, or where they
may be measured in terms of truckloads. However, this method is
not possible in case of heterogeneous commodities, which are hard
to add in terms of physical units, or truckloads. Drug industry and
textile industry offers examples of this type. Here, quantity
discounts are based upon the rupee value of the quantity ordered.
Rupee becomes a common denominator of value.
Quantity discounts based on physical units become important
where the cost of packing is a significant factor and orders of less
than standard quantities, say, less than a case of 6 pressure
cookers, may involve higher packing charges per cooker. Since the
space remains unutilised, the quantity discounts may be employed
to induce full-case purchasing. In some cases, sellers may clearly
mention that packing charges will be the same whether you
purchase a full case or less than a full case. Here also, the buyer
may like to go for a full case and in essence avail himself of the
quantity discounts. Discounts based on physical units are less likely
to be distorted by changes in prices.
In some cases, to prompt large orders, it may he specified
that orders up to a certain size will not be entitled to any discount.
But beyond this size, the customer would be entitled to a discount
for his extra purchases over and above the minimum size. The
discount rates may vary with successive slabs of quantities ordered.
Alternatively, discount may be allowed on the entire purchases
provided they exceed a certain minimum. In some cases, quantity
discounts mflY be based on the cumulative purchases made during
the particular period, usually at year or a. season, e.g., Diwali
discounts may be given on the basis of cumulative purchases made
during the Diwali season spread over September to Novembe'r. This
is different from quantity discounts based upon individual lots
ordered at a time. These discountS ensure customer loyalty and
discourage purchasing from several competitors simultaneously, but
the limitation of cumulative discounts is that, they do not tackle the
problem of high cost of servicing small orders, because, buyers get
no incentive to order for bigger lots and to avoid hand-to-mouth
purchasing. Buyers may be inclined to place larger orders towards
the end of the discount period to qualify for higher discounts. This
may disrupt the production schedule of the manufacture .
The following genital conclusions can be reached:
• Individual order size is a' better basis than cumulative
purchases made during a particular period.
Discounts based on the quantity of individual commodities
ordered have advantages over those based on the total size
of mixed commodities ordered.
Physical units are preferable to rupee value as a measure of
order size on which to base quantity discounts.
Objectives of Quantity Discounts
One important objective of quuntity discountS' is to reduce the
number of small orders and thereby avoid the high cost of servicing
them. Quantity discounts can facilitate economic size orders in
three ways:
A given set of customers is encouraged tbbuy the same
quantity batiste bigger lots.
The customers may be 'induced to give the seller a larger: ihare
of their total requirements by giving preference over,
competitors.
Small size purchasers may be discouraged and bigger size
customers may' be attracted.
Quantity discount system enables the dealer to reap
economies of buying in lager lots. These economies may enable
the dealer to charge lowler prices from the customers thereby
benefiting the customers. Finally, lower prices to customers may
increase the demand for the commodities, which in turn may
enable the dealer to purchase larger quantities, reaping still
greater discounts, and the manufacturer to reap economies of
large-scale production, The advantages to the manufacturer, dealer
and customer are as such circular. In fact, in many cases discounts
become a matter of trade custom.
A noted disadvantage of quantity discounts is that dealers may
often find it cheaper to purchase from wholesalers availing
themselves of these quantity , discounts than from the
manufacturer directly. This is because the wholesalers may pass on
some of their discounts to the dealers. This may ultimately affect
the image of the manufacturer in the minds of the dealers. Again, if
the seller becomes dependent upon a few buyers, they may be
able to dictate, his policies ap.d practices. But if his product is
sufficiently differentiated or his service' is unique, he may find it
possible and worthwhile to pursue an independent discount policy.
Quantity discounts are most useful in the marketing of materials
and Applies but are rarely used for marketing equipment and
components.
Quantity discounts have attracted the attention of the
Monopolies and Restrictive Trade Practices Commission. The
Commission conceded the claim of Reckitt and Coleman of India
Ltd., that it was entitled to gateway under Section, 38(1) (h) of tlie
Act in respect of discounts given on larger orders. It was held that
the Company’s price structure did not directly or indirectly restricts
competition to any material degree. However, some time later, the
Commission extnicted an assutance from the five manufacturers of
grinding wheels that they would give up the practice of discounts
based on the quantity. Their practice of pricing on ‘slab’ Basis' was
alleged to give advantage to buyers of larger quantities compared
to Players of smaller quantities.
Cash Discounts
Cash discounts are price reductions based on promptness of
payment. An example of discount can be "2 per yent off if paid in
ten days, full invoice price in 30 days." In practice, the size of cash
discount may vary widely. Cash discount is a convenient device to
identify and overcome bad credit risks. In certain trades where
credit risk is high, cash discount would be high. If a buyer decides
to purchase goods on credit, this reflects his weak bargaining
position, and he has to pay a higher price by forgoing the cash
discount. There is another way to look at cash dis.counts. Though
cash discounts encourage prompt payment, yet allowing of cash
discount also involves certain costs.
These costs have to be compared with the cost of carrying the
account, viz., locking up of working capital, expense of operating a
credit and collection department- and risk of bad debts and
alternative ways of attaining prompt settlements. By prompt
collections, manufacturers reduce their working capital
requirements and thus save their interest costs. However, allowing
discounts may involve paying 36.5 per cent in order to save 15 per
cent. Thus it is the reduction in collection expenses and in risks
rather than savings on interest, which should be the guiding
consideration for cash· discounts. The main point of distinction
between cash discounts and quantity discounts is that the former
are price reductions based on promptness ·of payment whereas the
latter are price reductions depending on the quantities purchased
(physical units or rupee value of the quantity purchased). As such,
cash discounts induce prompt payments or collections whereas
quantity discounts induce buying in large quantities.
Time Differentials
Charging different prices on the basis of time is another kind of
price
discrimination. Here the objective of the seller is to take advantage
of
the fact that buyer' demand elasticity varies over time. Two broad
types of time differentials may be distinguished:
Clock-time differentials,
Calendar-time differentials.
Clock-time Differentials: When different prices are charged
for the sMne service or commodity at different times within a 24
hours period, the price differentials are known as clock-time
differentials. The common examples of these are the differences
between the day and night rates on trunk calls, differences between
morning and regular shows in cinema houses, and different tates
charged' for electricity sold to industrial users during peak load
hours (day time) and offpeak load hours. In the case of telephone
services, day timing is the period of more inelastic demand and the
night time is the more elastic demand period. Two conditions, which
make the clock-time differentials profitable are as follows:
Buyers must have a definite and strong preference for
purchasing at certain timings over others giving rise to
significant differences in demand elasticity.
The product or service must be non-storable either wholly or in
parts, i.e., the buyer must consume the entire product at one
time when and for which he pays. In case the product is
storable, it will be purchased at lower rates to be used later
when needed making price differential a losing proposition.
Calendar-time Differentials: Here price differences are
based on a period longer than 24 hours; for example, seasonal price
variations in the case of winter clothing's, or betel accommodation
at hill and tourist stations. Here, the objective is also to exploit the
time preferences of the buyers.
Geographical Price Differentials
Geographical price differentials refer to price differentials based on
buyers location. The objective here again is to minimise the
differences in transport costs due to the varying distances between
the locations of the plants and the customers. There are various
types of geographical price differential, which are explained below:
FOB factory pricing: It implies that the buyer pays all the
freight and is responsible for the risks occurring during transport
except those that are assumed by the carrier. The advantages of
FOB factory pricing are as follows:
It assures u uniform net price on nIl shipments regardless of
where they go.
No risk is assumed by the seller.
The seller is not responsible for delay in carriage.
Postage stamp pricing: Postage stamp pric1rg means
charging the same delivered price for all destinations irrespective of
buyers' location. The quoted price naturally includes the estimated
average transportation costs. In effect, these prices become
discriminatory, that the short distance buyers have to pay more for
transportation than the actual costs involved while long distance
buyers have to pay less than the actual costs of transporting goods.
Postage stamp pricing is most Hnmonly employed for goods of
popular brands and having nation wide distribution. The basic idea
is to maintain a uniform retail price at all places. This common retail
price can also be advertised throughout the country. Bata footwears
provide the best example of postage stamp pricing other examples
are Usha sewing machines and fans, radios, pressure cookers,
typewriters, drugs and medicines, newspapers and magazines, etc.,
Postage stamp pricing is most suitable in case of products
where transportation costs are significant. It can also be used with
advantage by manufacturers to avoid the disadvantage of location
being far away from the main customers who if charged on the basis
of actual costs might have to pay much more and hence refrain
from purchasing. This advantage is particularly striking in the case
of products involving high transportation costs. This pricing gives a
manufacturer access to all markets regardless of his location.
Market access is particularly important when products of the rivals
are substantially the same.
Zone pricing: Under zone pricing, the seller divides the
country into zones and regions and charges the same delivered
price within each zone, but different prices between different zones.
For example, Parle Company has divided the country into 9 zones,
the intra-regional price differentials ranging between 5 and 15 per
cent approximately. Generally speaking, zone pricing is preferred
where the transportation cost on goods is too high to permit their
sale throughout the country at uniform price. The more significant
the transportation costs, the greater the number of zones and
smaller their size. Conversely, for product involving lower
transportation costs, zones are generally few but big in size. In
India, zone pricing has been widely used invanaspati and sugar
industries.
Basing point pricing a basing point price consists of a factory price
plus transportation charges calculated with reference to a particular
basing point. Under this system, the delivered price may be
computed by using either single basing point or multiple basing
points. In the single basing point system, all sellers (irrespective of
the locations) quote delivered prices, which arc the sum of the
basing point price and cost of transport from the basing point to the
particular point of delivery. Thus, the delivered prices quoted by all
sellers for a given point of delivey are uniform regardless of the
point from which delivery is made. In the multiple point pricing
system, two or more producing centres are selected as basing
points, and the seller then quotes a delivered price equal to the
factory price plus transportation costs from the basing point nearest
to the buyer. Rasing-point pricing has been widely used in the USA,
especially in the steel industry where at first the single basing-point
system known as Pitts burgh plus was employed. It was followed by
mulliple basing point pricing when Pittsburgh plus was declared
illegal.
Consumer Category Price Differentials
Price discrimination is frequently practised according to consumer
categories in the case of public utilities, for examples, electricity,
transportation, etc. Electricity firms quote different rates for
residential consumers and industrial consumers. The rates may also
differ for domestic power, light and fan. Railways also charge
differently from children to adults. They also charge differently -on
different classes of goods and different classes of passengers.
Personal Price Discrimination
Price concessions are commonly made to individuals at times for
personal considerations. For instance, special prices may be given
to companies own employees, shareholders or personal
acquaintances. These special prices may take several forms such as
additional services free of cost, leniency in fixation of prices for
used goods in exchange of new ones and extending credit, interest-
free credit.

LESSON – 4
PRODUCTION FUNCTION
The term "production function" refers to the relationship between
inputs used and outputs produced by a firm. The terms "factors of
production" and "resources" are used interchangeably with the term
"inputs". The relationship is purely physical or technological in
character and therefore it ignores the prices of inputs and outputs.
The study of the production function is aimed at achieving the
maximum output. This can be done with a given set of resources or
inputs, and with a given state of technology. The production
function can be expressed in the form of a schedule. Table 4.1
shows two inputs viz; labour [X], i.e., number of workers, and capital
[Y], i;e., size of machine in terms of horsepower, and one output (Q),
i.e., the number of tonnes of iron produced with the various
combinations of inputs.
Table 4.1: Production Function
Capital (Y) - Size of machines (in horse power)250 1,000 1,500 2,000
Labour (X) 1 2 20 32 26(Number of 2 4 48 58 88workers) 3 8 88 110 100
4 12 110 120 1105 32 120 124 1206 58 124 126 1247 88 126 128 1288 100 126 130 1309 110 126 130 13210 104 124 130 134
The production function can also be stated in a form of an
eqation:
Q = f (X1, X2, etc.),
Where Q = A function ofthedesired output as a result of utili
sing the quantity of two or more inputs
Xl = units of labour,
X2 = units of machinery.
Some factors of production are assumed to be fixed (i.e., not
varying with changes in output); and hence are not included in the
equation. The production function is estimated by the method of
least squares.
In economic theory, we are concerned with three types of
production functions, viz.,
Production function with one variable input.
Production function with two variable inputs.
Production function with all variable inputs.
PROPUCTION FUNCTION WITH ONE VARIABLE INPUT
In economics, the production function with one variable input is
explained with the help of'Law of Variable Proportions', which is as
follows:
Law of Variable Proportions
The law of variable proportion is one of the fundamental laws of
economics. It is also known as the 'Law of Diminishing Marginal
Returns' or the 'Law of Diminishing Marginal Productivity.' This Law
of variable proportion shows the input-outPut relationship or
production function with one variable factor, i.e., a factor, which can
be changed, while other factors of production are kept constant.
This is explained with the help of the following example:
Suppose a farmer has 20 acres of land to cultivate. The land
has some fixed investment, Le., capital in the form of a tube well,
farmhouse and farm maehinery. The amount of land and capital is
supposed to be fixed factors of production. However, the farmer can
vary the number of workers employed on its land. Labour is thus the
variable factor of production. The change in the number of workers
will change the output.
The point worth noting here is that the law does not state that
each and every increase in the amount of the variable factor that is
employed in the production process will yield diminishing marginal
returns. It is, however, possible that preliminary increases in the
amount of a variable factor may yield increasing marginal returns.
While increasing the amount of the variable factor, a point will " be
reached though, where the; marginal increases in total output or
the marginal retums will begin declining.
Assumptions for Law of Variable Proportions
The law of variable proportions functions is based on following
assumptions:
Constant technology: The technology is assumed to be
constant because technological changes will result into rise of
marginal and average product.
Snort-run: The law operates in the short-run because it is
here that some factors are fixed and others are variable. In
the long-run, all factors are variable.
Homogeneous input: The variable input employed is
homogeneous or identical in amount and quality.
Use of varying amount of variable factor: It is possible to
use various amounts of a variable factor on the fixed factors
of production.
Three Stages of Production
A graphic description of the production function is shown in
following figure 4.1. The total, marginal and average product curves
in Figure 4.1, demonstrates the law of variable proportions. The
figure also shows three stages of production associated with law of
variable proportions. The total product curve is divided info three
segments popularly known as three stages of production, which are
as follows:
Stage I
The figure 4.1 shows stage 1 as the segment from the origin to
pointX2. Here, total product (TP) rises at an increasing rate. At this
point, the marginal product (MP) of X equals its average product
(AP). X2 is, also the point at which the average product is
maximised. In this stage, the production function is characterised
first by increasing marginal returns from the origin to point X1and
then by diminishing marginal returns, from X1to X2. It should not be
assumed that in stage 1, only increasing marginal returns take
place. Because increasing returns may occur until a certain point,
and thereafter diminishing returns may take place. Stage I should
not therefore be identified with increasing marginal returns only.
Here, both AP and MP increase. In this stage, a firm can move
towards optimum combination of factors of production and
increasing returns, by adding more and more variable units to fixed
factors.
Stage II
The stage II is depicted by the figure in the range from X2 to X3. In
othcr words, stage II begins where the average product of the
variable factor is maximised. It continues till the point at which total
product is maximised and marginal product is zero. Here, TP rises at
diminishing rate. This stage is thus, called the stage of diminishing
returns, where a firm decides its level of production.
Stage III
Finally, we have stage III, which is depicted by the area beyond X3
where the total product curve starts decreasing. Here, too much
variable input is being used as related to the available fixed inputs
and thus variable inputs' are overutilized. The efficiency of both
variable inputs and fixed inputs decline through out this stage. In
this range, the marginal product of the variable factor is negative. It
starts from the point where MP is nil and TP is maximum and covers
the whole range of negative marginal productivity. The following
Table 4.2 shows the various stages.
Table 4.2: Stages of Production
Total Physical
Product
Marginal Physical Average PhysicalProduct Product
Stage IIncreasing at an Increases, reaches Increases and reachesincreasing rate maxiIhum and then its maximum
declines till MR = APStage IIIncreases at diminishing Is diminishing and Starts diminishingrate till it reaches becomes equal to maximumStage IIIStarts declining Becomes negative Continues to decline
From this stage-wise description of the production function we
can reach two conclusions, which are as follows:
Stage II is Rational
Only stage II is rational and denotes the relevant range-within which
a rationai firm should operate. In Stage I, it is profitable for the fiim
to keep on increasing the use of labour and in Stage, III, MP is
negative and hence it is inadvisable to use additional labour. The
firm, therefore, has a strong incentive to expand through Stage I
into Stage II.
Stages I and /II are Irrational
Stages I and III are described as irrational stages. They are called so
because management, if it is to maxi mise profits will never
intentionally apply the variable to the fixed factors in any
combination, which will yield a total product falling in either of these
two stages.
PRODUCTION FUNCTION WITH TWO VARIABLE INPUTS
To understand a production function with two variable inputs, it is
necessary to explain what is an ' Isoquant'.
Isoquants
An isoquant is also known as an 'iso-product curve', 'equal product
curve' or a 'production indifferent curve'. These curves show the
various combinations of two variable inputs resulting in the same
level of output. Table 4.3 shows how different pairs of labour and
capital result in the same output.
Table 4.3: Different Pairs of Labour and Capital
Labour Capital Output(Units) (Units) (Units)
I 5 10
2 3 10
3 2 10
4 1 10
5 0 10
It is evident that output is the same either when 4 units of
labour with 1 unit of capital or 5 units of labour with 0 units of
capital are employed. This relationship, when shown graphically
results in an isoquant. Thus, by graphing a production function with
two variable inputs, one can derive the isoquant that helps in
tracing all the combinations of the two factors of production that
yield the same output. Thus, an isoquant can be defined as "the
curve passing through the plotted points representing all the
combinations of the two factors of production, which will produce
the given output." Figure 4.2 depicts a typical isoquant digram in
which by an upward movement to the right, one can obtain higher
levels of outputs, using larger quantities of output. For each level of
output, there will be different isoquant. When the whole array of
isoquants is represented on a graph, it is called 'isoquant map'.
Substitutability of Inputs
An important assumption regarding the isoquant diagram is that
the inputs can be substituted for each other. For example a
particular combination of X and Y results in output quantity of 600
units. By moving along the isoquant 600, one finds other
quantities of the inputs resulting in the same output. Let us
suppose that X represents labour and Y represents machinery. If
the quantity of the labour (X) is reduced, the quantity of
machinery (Y) must be increased in order to produce the same
output. The following Figure 4.2 shows a typical isoquant.
Marginal Rate of Technical Substitution (MRTS)
The slope of the isoquant has a technical name; Marginal Rate of
Technical Substitution (MRTS) or sometimes, the marginal rate of
substitution in prodtltioti.) Thus, in terms of inputs of capital
services K and Labour L.
MRTS = aK/dL
MRTS is similar to MRS, I.e., Marginal Rate of Substitution,
(which is slope, of an indifference curve).
Types of Isoquants
Isoquants assume different shapes depending upon the degree of
substitutability of inputs under consideration. Based on this the
types of isoquants can be enlisted as follows:
Linear Isoquants: In the case of linearisoquants, there is
perfect substitutability of inputs. For example, a given output
say 100 units can be produced by using only capital or only
labour or by a number of combinations of labour and capital,
say 1 unit of labour and 5 units of capital, or 2 units of labour
and 3 units of capital, and so on. Likewise, a giyen power
plant that is equipped to burn either oil or gas, for producing
various amounts of electric power can do so by burning either
gas or oil, or varying amounts of each. Gas and oil are perfect
substitutes here. Hence, the isoquants are straight lines. The
following Figure 4.3 shows the isoquant for oil and gas.
Right Angle Isoquant: When there is complete non-
substitutability between the inputs (or strict complimentarily)
then the isoquant curves take the form of right angle
isoquants. For example, exactly two wheels and one frame
are required to produce a bicycle and in no way can wheels be
substituted for frames or vice-versa. Likewise, two wheels and
one chassis (The rectangular, steel frame, supported on
springs and attached to the axles, that holds thepody and
motor of an automotive vehicle) are required for acooter. This
is also known as 'Leontief Isoquant' or Input-output isoquant.
The following Figure 4.4 shows the isoquant for chasis and
wheels.
Convex Isoquant: This form of isoquants assumes
substitutability of inputs but the substitutability is not perfect.
For example, in Figure. 4.5 a shirt can be made with relatively
small amount of labour (L1) and a large amount of cloth (C1).
The same shirt can be as well made with less cloth (C2), if
more, labour (L2) is used because the tailor will have to cut
the cloth more carefully and reduce wastage. Finally, the shirt
can be made with still less cloth (C3) but the tailor must take
extreme pains" so that JabourinpiJt requirement increases to
C3. So, while a relatively small addition of labour from L1 to L2
allows the input of cloth to be reduced from C1 to C2, a very
large increase in labour from L2 to L3 is needed to obtain a
small reduction in cloth from C2 to C3. Thus the substitutability
of labour for cloth diminishes from L1 to L2 to L3. The following
Figure 4.5 shows isoquant for cloth and labour.
Main Properties of Isoquants
All the above-mentioned isoquants are featured with some
common properties, which are as follows:
An isoquant is downward sloping to the right, i.e., negatively
inclined. This implies that for the same level of output, the
quantity of one variable will have to be reduced in order to
increase the quantity of other variable.
A higher isoquant represents larger output. Jhat is, with the
same quantity, of one input and larger quantity of the other
input, larger output will be produced.
No two isoquants intersect or touch each other. If two
isoqua~tsinter.seCt or touch each other, this would mean
that there will be a common point the Two curves; and this
would imply that the 'same amount of two inputs could
produce two different levels of output (i.e., 400 and 500
units), which is absurd.
Isoquant is convex to the origin. This means that its slope
declines from left to right along the curve. In other words,
when we go on increasing the quantity of one input say
labour by reducing that quantity of other input say capital,
we see that less units of capital are sacrificed for the
additional units of labour.
PRODUCTION FUNCTIONS WITH ALL VARIABLE INPUTS
A closely related question in production .economics is how a
proportionate increase in all the input factors will affect total
production. This is the question of returns to scale, which brings to
mind three possible situations:
If the proportional increase in all inputs is equal to the
proportional increase in output, returns to scale are constant.
For instance, if a simultaneous doubling of all inputs results in
a doubling of production then returns to scale are constant.
The following figure 4.6 shows a constant rate to scale.
If the proportional increase in output is larger than that of the
inputs, then we have increasing returns to scale. The following
Figure 4.7 shows increasing returns to scale.
If output increases less than proprotionally with input
increase, we have decreasing returns to scale. The following
Figure 4.8 shows decreasing returns to scale.
The most typical situation is for a productin function to have
first increasing then decreasing returns to scale is shown in Figure
4.9.
The increasing returns to scale attribute to specialisation. As
output increases, specialised labour can be used and efficient, large-
scale machinery can be employed in the production process.
However beyond some scale of operations further gains from
specialisation are limited, and co-ordination problems may begin to
increase costs substantially. When co-ordination price is more than
offset additional benefits of specialisation, decreasing returns to
scale begin.
Returns to Scale and Returns to an Input
Two important features of production functions are returns to scale
and returns to input, which are explained as follows:
Returns to scale: These describe the impact on the output
when the same proportion increases each input rate. If output
increases by a larger percentage than the increase in each input
then there are increasing returns to scale. Conversely, if output
increases by a smaller percentage, there are diminishing returns to
scale and if it increases by the same proportions there are constant
returns to scale.
Returns to input: These describe the impact on the output
when only one input is varied, holding all others constant. These
returns may be increasing,' diminishing, or constant.
Optimal Input Combinations
From the overall discussion so far itisobvious that production
function, has a pure 'physical or technological' character. However,
it does not tell which input combinations are optimal. For that
purpose, one has to take into account the input prices. The following
Figure 4.10 shows the iscost curves.
Isocost Curves
In this connection, one has to consider yet another but important
diagram consisting of isocost curves. Here also, the axes represent
quantities of the inputs X and Y. Suppose that the prices of the
inputs are given, and there are no quantity discounts for the firm to
get larger quantities at lower prices. The next step will be to plot the
various quantities of X and Y which may be obtained from the given
monetary outlays. Figure 4.10 shows the resulting isocost curyes,
which are straight lines under the assumption made here. One
isocost showing the quantities of X and Y that can be purchased for
Rs. 1,000 and another isocost curve showing the quantities of X and
Y which can be purchased for an expenditure of Rs. 2,000 and so on.
Now we can easily superimpose the isocost diagram on the
isoquant diagram (as the axes in both the cases represent the same
variables). With the help of Figure 4.11, it can be ascertained that
the maximum output for a given outlay, is say Rs. 2,000. The
isoquant tangent represents this maximum output, which is possible
with this outlay, to the isocost curve. The optimum combination of
inputs is represented by point E, the point of tangency. At this point,
the marginal rate6f substitution (MRS, sometimes known as the rate
of technical substitution), between the inputs is equal to the ratio
between the prices of the inputs.
Likewise, in order to mini mise the cost for a given output, one
may again refer to the isoquant and isocost curves in Figure 4.11. In
this case one moves along the isoquant representing the desired
output. It should be clear that the minimum cost for this input is
represented by isocost line tangent to the isoquant.
Firm's Expansion Path
A firm's expansion path is defined by the cost-minimising
combination of several inputs for each output level. Thus the line
representing least cost combination for different levels of output is
called firm's expansion path or the scale line shown by line ABC in
Figure 4.12.
MEASUREMENT OF PRODUCTION FUNCTION
Several types of mathematical functions are commonly used for
measuring production function but in applied research, four types
are used extensively. These are linear functions, power functions,
quadratic functions and cubic functions.
(1) Linear Function
A linear production function is expressed as follows:
Total product: Y = a + bX, where Y = output and X = input. From
this function, equation for average product will be
Y/X=a/X+b
The equation for the marginal product will
be Y/X = b
(2) Power Function
A power function expresses output, Y, as a function of input X in the
form:
Y = aXb
Some important distinctive properties of such power functions
are:
The exponents are the elasticities of production. Thus, in the
above function, the exponent 'b' represents the elasticity of
production.
The equation is linear in the logarithms, that is, it can be
written as: log Y = log a + b log X
When the power function is expressed in logarithmic form as
above, the coefficient represents the elasticity of production.
If one input is increased while all others are held constant,
marginal product will decline.
(3) Quadratic ProductionFunction
The production function may be quadratic and is expressed as
follows:
Y = a + bX = cX2
Where the dependent variable, Y, represents total output and the
independent variable, X, denotes input. The small letters are
parameters and their probable values are determined by a
statistical analysis ofthe data.
The distinctive properties of the quadratic production function
are
as follows:
The minus sign in the last term denotes diminishing marginal
returns.
The equation allows for decreasing marginal product but not
for both inerellsing and decreasing marginal products.
The elasticity of production is not constant at all points along
the curve as in a power function, but declineswiih input
magnitude.
The equaItion never allows fotan increasing marginal product
When X = 0, Y = a, this means that there is some output even
when no variable input is applied.
The quadratic equation has only one bend as compared with a
linear equation, which has no bends.
(4) Cubic Production Function
The cubic production [unction is expressed as follows:
Y = a -I- bX -I- cX2 – dX3
Some important distinctivc properties of a cubic production
function arc as follows:
It allows for both increasing and decreasing marginal
productivity.
The elasticity of production varies at each point along the
curve.
Marginal productivity decreases at an increasing rate in the
later stages.
PRODUCTION FUNCTION AND EMPIRICAL STUDIES
The measurement of production function dates back to a century
when certain r pioneer studies were made in the field of agriculture.
And though economic concepts and statistical techniques have now
advanced a lot, its major work is still in agriculture.
Cobb-Douglas Function
A very popular production function, which deserves special mention,
is the CobbI Douglas function. It relates output in American
manufacturing industries from 1899 to 1922 to labour and capital
inputs, taking the form.
P = bLaC1 - a
Where,
P = Total output
L=Index of employment of labour in manufacturing
C = Index of fixed capital in manufacturing.
The exponents ‘a’ and ‘1 – a’ are the elasticity of production
that is, ‘a’ and ‘1- a’ measure the percentage rexsponse of output
to percentage changes in labour and capital respectively. The
function estimated for the USA by Cobb and Douglas is:
P = 1.01L.75C25
R2 = .94.09
This production function shows that a 1 per cent change in
labour input, with the capital remaining constant, is associated with
a 0.75 per cent change in output. Similarly, a 1 per cent change in
capital, with the labour remaining constant, is associated with a
0.25 per cent change in output. The coefficient of determination (R2)
means that 94 per cent of the variations on the dependent variable
(P) were accounted for, by the variations in the independent
variables (L and C).
An inportant point to note is that the Cobb-Douglas function
indicates constant returns to scale. That is, if factors of production
are each increased by 1 per cent, the output will increase by 1 per
cent. In other words, one can assume constant avberage and
marginal production costs for the US industries during the period.
The following Figure 4.13 shows the graph of Cobb-Douglas
production.
Criticism
The production function ordianrily discussed in economics is a
rigorously developed micro-economic concept. However,
Douglas and his colleagues, estimated production function for
nation’s economies for manufacturing sectors and even for
industries. Thus they “transferred” strictly micro- economic
concept to a macro-econornic setting, without sufficiently
justifying their act on logical economic grounds. Therefore,
the result of their studies, in the form of equations which they
derived, may be incorrect, and hence the interpretations
based on their equations are uncertain.
The production function of economic theory assumes that the
quantities of inputs used are those that are actually used in
production. Therefore no variable input is ever redundant. In
the Douglas studies however, only labour was measured by
the quantity actually used in production, while capital was
measured by the capital investment, i.e., the quantity
available for production. Therefore, with the possible'
exception of the years in which full employment and
prosperity prevailed and industry made reasonably fuil use of
the available inputs, the measure of capital employed was not
theoretically correct one. If annual capital input always
remained as a constant proportion of total capital investment,
then only the elasticity would be the same. In spite of this
criticism, the Cobb-Douglas type of production function has
been found useful for interpreting economic results, since the
elasticity of production; is given directly by the exponents
when the data are in original form, or by the regression
coefficients when the data are in logarithmic form.
MANAGERIAL USE OF PRODUCTION FUNCTIONS
Though production functions may seem to be highly abstract and
unrealistic, in fact, they are both logical and useful. If the price of a
factor of production declines whereas that of another goes up, the
former is likely to substitute the latter. The usefulness of the
production function can be explained with the help of an example,
dairy economists are interested in minimising the cost of feeding
cows in milk production. Taking a cow as a single firm, and grain
and roughage as inputs, the question arises: What proportion of
grain and roughage would be economical in feeding the cow? In the
past, there has been some tendency to prescribe a fixed ratio, but
economic analysis suggests that the optimal ratio depends on the
inptlt prices. For instance, if we draw isoquantsrelating various
quantities of grain and roughage, to various levels of milk output
and then superimpose isocost curves on the isoquant diagram, the
optimum point of largest output for a given outlay or of minimum
outlay for a given output-would depend on the prices of the factors
of production, and it would change as these prices change. The
dairy farmer can use such analysis for increasing the return from his
expenditure on feeds.
Certain economists have focused especially on the application
of their findings. For instance, Earl Heady and his associates have
developed a mechaniclIl device known as Pork Postulator, which
facilitates the farmer to determine the most profitable ration for
feeding pigs under different price conditions.
Production functions thus are not just theoretical and futile
devices. They can also be used as aids in decision-making because
they can give guidance in two directions regarding:
Obtainfng the maximum output from a given set of inputs
Obtaining a given output from the minimum aggregation of
inputs
Of course, in more complex problems, with larger numbers of
inputs and outputs, the mathematics of optimisation becomes
complicated. But recently, the development of linear programming
has made it possible to handle these complex problems. The use of
complex production functions in managerial decisiull making is
going to be further facilitated with the development of electrollic
computers.
DERIVING INPUT COMBINATIONS FROM
PRODUCTION FUNCTION Given a production function for a certain output, one can derive all
the combinations of the factors of production that will yield the
same output. This can be illustrated as follows:
IIIustration
Suppose the production function is:
0= 0.196 H 0.880 N 1.815
Where,
0= output oftransformers in terms of kilovolt-ampere (kVA)
produced
H = average hours worked per day
N = number of men.
Now, to derive the input combinations for an output level of
1,200 kVA, we will have to set the above equation equal to 1,200:
1,200 = 0.196 H 0.880 N 1.815
Then, substituting any value of H (or N) in the equation, we can
obtain the associated value of N (or H). We compute below the
number of hours required (H) for an output of 1,200 kVA, if 38 men
are employed.
1,200 = 0.196 H 0.880 N 1.815
log 1,200 = log 0.196 + 0.880 log H + 1.815 log N
= log 1,200 = log 0.196+ 0.880 log H + 1.815 log 38
In the same way, we can derive the value of H, if N is 40, 42,
44 and so on, if the desired output level is 1,200 KVA. We can also
derive various combinations ofH and N for other levels, say, 1,300
KVA or 1,400 KVA.
PRICE AND OUTPUT DECISION UNDER
VARIOUS MARKET SITUATIONS To understand the concept of market and its various conditions, it is
necessary to study the thcory orthe firm. This is discussed as
follows:
The Theory of the Firm
The basic, assumptions of the theory of the linn are as follows:
The objective of a firm is to maximise net revenue in the face
of given prices and technologically determined production
function.
A price incrcase far a product raises its supply, whereas prices
increase for a factor reduccs its demand.
The theory or lhe firm deals with the role of business firms in
the resource allocation process. It uses aggregation as a tactic
and attempts to specify total market supply and demand
curves.
The firm operates with perfect knowledge of all relevant
variable involved in making a decision and it acts rationally
while doing so.
Originally the theory assumed that the firm is operating within
a perfectly competitive market. But it has now been extended
to cover other market situutions.
The theory has been criticised in the context that profit
maximisation is not the only objective of a firm. It has been
suggested that long-run survival is the primary motive of an
entrepreneur. Though the importance of profit has not been denied,
many economists have argued that profit maximisation should be
replaced with a gonl of makll1g satisfactory profits. However, there
is a general agreement that the theory or the firm explains at a
general level, the way in which resources are alloclIted by the price
system, when profit is the main criterion used by the firms.
From the viewpoint of price analysis, it is very important for
business management to gain a proper understanding of the nature
and process of competition in the modem industrial society. The
management should undcrstllnd the rationale of the free enterprise
system within which its own business decisions have to be made
and the purpose and limitations of that system. Next it musl hnve
full knowledge of the markets and market situations in which its own
business operates. It should be aware of the policies appropriate to
those market situations. The management should also have an
understanding of the competitive process and the way variables
involved in the process such as price; product innovnt ion and
promotional activity may be manipulated in enlarging the firm's
market share. The firms having monopoly power should be familiar
with the nature and llie purpose of the law relating to monopoly and
restrictive practices. The management must also be alert and
should be able to recognise when market conditions change.
Experienced executiv.es cannot gain the intimate knowledge of the
ways or llicir competitors. Consequently it is necessary to obtain, an
understanding of the nature of competition, which can provide an
insight into the probable behaviour pnlll'llls of the competitors. To
study how prices are determined the types of market situations
need to be studied are as follows:
Perfect competition.
Imperfect competition
o Monopoly and monopsony
o Monopolistic competition
o Oligopoly and oligopsony.
PURE AND PERFECT COMPETITION
Perfect competition is a market situation where large number of
buyers and scllns operate freely and commodity sells at a uniform
price. In such a situation no seller or buyer has any influence on the
market price. In this market, a firm is the price taker and industry is
the price maker.
Main Features
The main features of perfect competition are as follows:
There are a large number of buyers and sellers. Each seller
must be small and the quantity supplied by any ne seller
must be so insignificant that no increase or decrease in his
output can appreciably affect the total supply and the
market price. So also, each buyer must be small and the
quantity bought by any of the buyers should be so
insignificant that no increase or decrease in his purchases
can· appreciably affect the total demand and the price. As a
result, each seller will accept the market price as it is. So
also each buyer will regard the price as determined by forces
beyond his control.
Each competitor offers a homogenous product, i.e. the
products are similar to ach other in terms of quality, size,
design and colour. Thus one product could be substituted for
the other if the price is lower. Again, the commodity dealt in
must be supplied in quantity.
There is no obstacle with regard to entry or exit of the firms.
When these aforesaid three conditions arc fulfilled there is a
market condition that can be defined as a pure competitive
market.
The market iil which the commodity is bought and sold is
well organised and trading is continuous. Therefore, buyers
and sellers are well informed about the price of the
commodities.
There are many competitors (whether buyers or sellers),
each acting independently. There must be no restraint upon
the independence of any seller or buyer, either by custom,
contract, collusion, and fear of reprisals by the competitors,
or by the imposition of government control.
The market price is flexible over a period of time. In other
words, it rises or falls constantly in response to the changing
conditions of supply and demand.
All the firms have equal access to production technologies
and techniques.
There are no patents, proprietary designs or special skills
that allow an individual firm to do the job better than its
competitors.
Firms also have equal access to all their inputs, which are
available on similar terms.
Thus, perfect competition in an extreme case and is rarely to
be found. Actual competition always departs from the ideal of
perfection Perfect competition is a mere concept, a standard by
which to measure the varying degrees of imperfect competition.
Sometimes, a distinction is made between perfect competition
and pure I competition. But the line of distinction drawn between
the two is very fine. That is why many economists have preferred to
use the two terms synonymously. Hence, from managerial
viewpoint, there does not seem to be any difference between the
two. The underlying presumption in a free competition (close to
perfect cmpetition) is that it social interest interest unless the
contrary can be proved. Competition safeguards the consumer
against exploitation by providing the buyer with alternatives, and
makes it unnecessary for the state to intervene by regulating
process and production in order to protect him.
Determination of Price
The forces of demand and supply determine prices under perfect
competition. The equilibrium price is obtained at the intersection of
demand and supply curves as shown in following Figure 4.14. The
equilibrium price will change only with changes in forces of
demand and supply.
Price and Quantity Variability
Responses to a cnange in demand or to a change in supply may be
primarily in price or quantity. If the demand is highly elastic,
consumers will respond readily to price changes by dropping out of
the market when prices are lowered'a little. As a result, most of the
adjustments to changes in supply (an increase leading to a
reduction in price and a decrease leading to an increase.in price)
would be those in quantity purchased, if the demand is highly
elastic. If the demand is inelastic, the adjustments will take place
primarily in price. Similarly, if sellers respond readily by greatly
increasing their offerings on slight increases in price or by heavy
withdrawals in slight price drops, the adjustments to changes in
demand willbe largely in quantity exchanged. If sellers are quite
responsive to, price in their offerihgs (if supply is very inelastic), the
adjustments to changes in demand, will take place largely through
shifts in price. In view of the above explanation, 'we may state
thefollowing rules:
If demand rises then price goes up and vice versa. For
example, in Figure. 4.15, the demand curve shifts. upwards, to
the right from DD to D’D’ whereas the supply curve remains
the same. As a result, the price goes up from OP to OP1. Thus,
the sales increase from OQ to OQ1. If supply rises then the
price decreases and vice versa. For example, in Figure. 4.16,
the supply curve shifts downward to the right from SS to S’S’
while the demand curve remains unchanged. The result is that
price falls from OP to OP1. Dul the sales increase from OQ to
OQ1. The following Figures 4.15 and 4.16 shows shift in
demand curve and shift in supply curve due to increase in
price, respectively.
Given a shin in the demand curve the following can occur:
Price will rise less or falllcss if the supply curve is elastic
(flat)
Price will rise more or fall more if the supply curve is
inelastic (steep)
If the rise in price is more than the rise in sales will be less
If the rise in price is less than the rise in sales will be more
For example, in Figure 4.17, the demand eurve shifts from DD to
D’D’.
The supply curve S"S" is steep. Another supply curve S'S' is
rather flat. Both the supply curves cut the original demand curve at
point E giving the equilibrium prices as OP. The flat supply curve S'S'
cuts the new demand curve D'D' at E2 giving the equilibrium price as
OP2, which is less than OP1 and more than OP.
In the same way the following will occur when there is a shift
in the supply curve
o The price will rise less or fall less if demand curve is
elastic
o The price will rise more or fall more if demand curve is
inelastic.
For example, in Figure 4.18, SS is the original supply curve,
S'S' is the new supply curve, D'D' is the steep demand curve
(indicating relatively inelastic demand) and D”D” is the flat curve
intersecting the supply curve at point E. After the shift in the supply
curve, however, the S'S' cuts the D'D' curve at point E' giving OP' as
the equilibrium price. But the SS curve cuts the D"D" curve at point
E giving the equilibrium price as OP which is higher than OP'.
If both demand and supply increase, sales are bound to
increase but the price mayor may not increase. In this case
there case can be two possibilities
o Price will rise if the amount, which will be
demandedattheold price exceeds the supply, which will
be made at that old price as shown in Figure 4.19.
o But the price will fall if the amount, which will be
supplied at the old price, is more than the amount
demanded currently at that price as shown in Figure
4.20. In other words, if at the old price, new demand
exceeds the new supply, the price will rise but if the new
demand is less than the new supply, the price will fall.
An increase in demand with a simultaneous decrease in
supply will raise price and increase sales if the new demand price
for the old equilibrium amount is higher than its new supply price.
Similarly, the price will rise and sales will dimfnish if the new supply
price for the old amount is higher than itsnew demand
GOVERNMENT INTERVENTION IN PRICE FIXING
Quite often the government interferes with the normal process of
price determination by fixing prices either above the equilibrium
level or below it. In order to make these attempts by the
government about artificial price fixation successful, government
intervention is required with the forces of supply or demand or both,
through elaborate administrative regulations.
Difficulties in Price Fixing
The government has to face several difficulties while fixing prices
due to certain reasons. There can be elaborated as follows:
Attempts to fix prices above an equilibrium level are
illustrated by minimum wage legislation and price support
policies. When the Government undertakes the activity of
fixing a minimum price say, Rs. 375 per quintal for wheat
much above the equilibrium price say, Rs. 300 per quintal,
consumers restrict their consumption of 'wheat' (postpone
their purchases at all levels). Conversely, farmers are
encouraged to increase their production under the incentive
of higher' prices. This results in disequilibrium between the
demand and supply. As such, there are only two ways to
maintain prices at a high level:
o The government can buy large quantities to absorb the
difference between the quantity supplied and quantity
demanded.
o The government can ask the farmers to limit their
output.
The government also tries to set maximum prices below the
equilibrium level. This is illustrated by the price control on
sugar, on steel and a number of othcr commodities. Let us
assume that the equilibrium price of sugar is Rs. 10.00 per
kilo but price has been controlled at Rs. 7.00. The suppliers
would hold back their supplies and this would leave a large
body of unsatisficd consumers. The problem would arise as to
who should get a sharclof the limited supply of sugar. There
would be long queues for the available supply. In short, lots of
difficulties would arise. The government would have t.o adopt
both-or either of the following measures:
o Introduction of rationing
o Payment of subsidey to sugar producers to neutralise
the
effects of low prices and to encourage them to produce
more.
In this way, the Government would substitute ration cards for
the rationing mechanism of a free-market system and it would
substitute subsidies for the price incentive of a free market the
following Figure 4.21 and 4.22 shows the demand for wheat and
sugar, respectively.
Effect of Time Upon Supply
Economists find it important to discuss the way in which supply
changes in the course of time. The reason why such a study is
necessary lies in the technical conditions of production, i.e., it
always takes time to make those adjustmcl'lts ill the size and
organisation of a factory, which are necessary for greater
production. For the purpose of analysis in this connection, it is usual
to follow the method of analysis used by Marshall. Marshall
suggested three periods of time namely market period, short period
and long period. Marshall considered the market period as being
only a single day or few days. The fundamental feature of the
market period is that it is supposed to be so short that supplies of
the commodity in question will be limited to the existing stocks or at
the most to the supplies in sight. Graphically, the supply curve will
be vertical, i.e., the supply remains fixed irrespective of the price.
The 'market period' supply curve is not applicable in all cases. lt
is particularly important in the case of perishable goods, which are
difficult or impossible to store, and in case of demand, which is
subject to short-run fluctuations.
Marshall defined short period as "a period long enough for the
supplies of a commodity to be altered by increase or decrease in
current output but not long enough for the fixed equipment to be
changed to produce a larger or a smaller output." In other words;
the short-run cost curve remains the same. Here, the supply curve
would be a slopmg lme, moving upward Irom left to right thereby
indicating that as price goes up, supply increases.
In the long period, as defined by Marshall, there is time to build
additional plants or clear more land for crops; or alternatively, old
machines and factories can be closed down. A firm producing at
overtime rates or by using standby equipment will usually plan to
increase output by buying new plants and machinery. It will do so
when provided that it thinks the increased demand will be
maintained. The long-period supply curve will, therefore, tend to
have a flatter slope than the shortrun supply curve indicating
thereby that given a price increase, the supply tends lo be larger
than in the short-run period.
EQUILIBRIUM AND TIME
The following discussion now concentrates on how price would be
determined in different time periods, given a change in demand.
In the market period, an upward shift in the demand curve
would result in an immediate rise in price, as there will be no
increase in supply.
This will be followed by greater production during the short
period and a fall in the price as firms increase their output.
Later, as more capital equipment is installed the output would
increase still further and prices would again drop. Conversely,
a downward shift in the demand curve would not immediately
affect the quantity supplies but the price would drop sharply,
followed by some recovery as the firms reduce output in the
short period.
In the long period, firms would see more profitable uses for
their plants and would decide not to replace capital output as
it wears out. This would reduce equipment still further and
permit some recovery in price.
Illustration
To take an example, in Figure 4.23 DD shows the demand for fish
whereas SS, S'S', and S"S" represent the market-period, short-
period and long-period supply curves respectively. Suppose the
demand for fish in the market shifts to D'D'.
Now, supply of fish cannot be increased immediately and hence
market or momentary equilibrium is established at price OP”.
In the short run, however, fish supply can be increased by a
more intensive use of the existing equipment, viz., boats and nets
and by working for longer hours. As a result, the price drops to OP".
In the long run, supply can be fully adjusted to meet the demand
conditions. New fishermen would be attracted (entry of new firms),
new boats; nets and other equipment would be produced and
employed in service. As a result, supply would increase further and
the long-run equilibrium would take place at a still lower price OP".
The Firm in Pure Competition
In pure competition, the firm has to accept the given market
price. At this given price, it can sell all the products, which it desires
but at any higherprice, it cannot sell anything. If the market price is
below its cost, it has to either take the loss or withdraw from the
market. As a result, any single firm in a purely competitive situation
has to adjust its production and sales policies to the given market
price. However, the market prices arc determined through the
mutual consent of all the individual competitive buyers and sellers
together. But any individual firm has no control over the price. Since
a purely competitive seller has no control over the price at which he
sells, his average marginal revenue schedule is infinitely elastic. In
perfect competition, marginal revenue is equal to the average
re.xenue, because every unit is sold at the same market price,
irrespective of the' quantity sold. Graphically, a horizontal line at the
market price represents it. As expansion of sales does not require
any reduction in the price at all; the greater the quantity sold, the
larger is the revenue. Under ordinary circumstances, the owner· of a
linn will not question whether to produce or not to produce. Rather
he will have to decide whether it will be bettcr to producc, say,
10,000 units or 11,000 units. In order to answer this question, hc will
compare thc incremental cost and tIll' incremental revenue resulting
(i'om thc altcrnative courses of action. To express in technical
terms, the maximum profit (or the minimum loss) position can be
attained by in.creasing output so long as the marginal revenue
continues to exceed the marginal cost. When marginal cost is above
the marginal revenue, an increase in output would reduce profits
and it would be better to decrease the output. If the amount of
marginal rcvenuc is greater than the marginal cost, it would be
beneficial to increase the output. Thus, profit is maximised, or the
loss is minimised, by increasing the output just up to the point a.t
which marginal cost equals marginal revenue.
Output Decisions and Consumer Interests
An entrepreneur will expand his output so long as the addition to his
cost is less than the worth of the incrcase in output price to the
consumers. In this respect, the entreprencur acts consistently with
the interests of the consumers though his purpose is merely to
maximise his own profits.
This rcquires continuing the hiring of additional workers and
buying additional raw materials so long as the wage paid for the
labour and the price paid for the matcrials is less than the amount
that every unit of output will add to his revenues. In this rcspect, the
entrepreneur acts in harmony with the interests of the sellers of
labour and raw materials though his purpose is to maximise his own
profits. A consistcney with the consumer preferences is also
maintained in bidding for the additional units of input for his firm.
Without being in the least a philanthropist, the purely competitive
entrepreneur seeking to maximise profits provides a very cffective
service in helping the allocation of resources in consistence with
consumer preferences and with the interests"of resource owners.
The Firm and Shutdown Point
The amount that a particular firm offers for scale in the short-run at
different prices for its product depends upon the cost conditions of
the firm. In case there is any price that is lower than the lowest
variable cost per unit, the firm will have to be shut down. It would
not be useful to operate even in the short run at a price lower than
this, sincc variablc costs are not covered. It is not held, however,
that in the short run, the average total costs play no role in the
output decisions of the prbfit-.seeking entrepreneur. This is because
the fixed costs, which are a component of the average total costs,
would remain unaffected by the decision to shut down.
The Decision to Operate at Loss or Shut down
The above discussion shows that in the short run any firm may
decide to operate at a loss but try to minimise it. However, the
question may well arise: Why should a firm operate at all when it is
suffering losses, and why should it not.shut down? The explanation
to the above question lies in the fixed costs, which a firm has to
incur any way. In the short-run, certain costs, for example, rent,
interest, etc., are fixed. They continue to exist whether the firm
operates or not. Even if the firm shuts down, it cannot avoid these
costs in the short-run. If, for example, these fixed costs are Rs.
1,000 per month, the firm will lose this amount every· month even if
it decides to cease operations.
Under these circumstances, it will be clearly beneficial to the firm
to continue operating if it can cover its variable costs and still have
something left to contribute towards its irreducible Rs. 1,000 every
month. Thus, supposing till' price is Rs. 40, output is 70 units and
the average variable cost is Rs. 35, the firm's receipts would be Rs.
800. Total variable cost will be Rs. 2,450 and the finll would be left
with Rs. 350 to meet part of its fixed costs. The net .loss to be
suffered would be RS.650 only. If the firm were to close down, its
loss would have been Rs. 1,000; hence it would decide to operate
even at a loss because by so doing, its losses would be less than
they would have been in the case of firm's shutdown.
If, however, the price comes down to Rs. 35 only and the
average variabe cost is Rs. 35, the sales receipts would just cover
total variable cost, leaving nothing towards covering the finn's fixed
costs. Hence, the firm would be indifferent and perhaps decide to
shut down. If price is below the average variable cost (Rs. 35), the
firm would fail to recover even its variable costs and would certainly
shut down. To conclude, therefore, the shutdown point is whcre
AVC=AR.
Consequences of Pure Competition
The consequences of pure competition can be enlisted as follows:
If the market price is below the cost of production of a
particular produccr, he can do nothing but to take a loss (in
the short run). If tbe price remains below his cost of
production for a sufficiently long period, he has no alternative
but to go out of business.
A firm can increase its profits by selling more units.
Products subject to a competitive market situation, face a
greater degree of price instability than is the case with
differentiated products.
No useful purpose is served by advertising. When products
sold by individual sellers are identical, advertising by anyone
seller would have a negligible effect on the demand for his
product.
Equilibrium of Industry
The short-term and long-term adjustment processes can be clearly
identified by understanding the concept of equilibrium of an
industry. These are explained as follow.
Meaning of Industry
The term industries are sometimes used in a broad sense so as to
include all the producers of a similar type of commodity such as
vanaspati industry or cigarette industry. It is sometimes used in a
narrow sense to include only the producers of commodities, which
are identical from the point of view of purchasers such as wheat or
more precisely still a particular grade of wheat. In a purely
competitive industry, however, the commodity is uniform and there
is no product differentiation, even in the slightest way. As such,
under perfect competition, an industry may be said to consist of all
firms producing a uniform commodity. It may be further added that
a firm, which produces more than one product, may be said to
participate in more than one industry. Strictly speaking, different
brands of cigarettes may be regarded as different commodities
because there are set consumer preferences for one brand over
another. Yet, these consumer preferences are so slight that for
many purposes all the standard brands may be regarded as one
commodity and the industry as a whole, for example, the cigarette
industry. Of course, the industry is said to be characterised by
product differentiation as different brands have different
characteristics to attract consumers.
Adjustment Process Towards Long-run Equilibrium in
Industry
An industry is said to be in equilibrium when there is no tendency on
the part of the firms within the industry to leave it or on the part of
the firms outside; to enter the industry. Long-run adjustments in an
industry take place through the entry or withdrawal of firms. These
are adjustments that take place over a time period I.ong enough to
permit such a shifting of firms and of relatively fixed productive
agents used by the firms. An industry is said to be in equilibrium
when there is no advantage to any productive agent in moving into
or out of the industry, or when there is no incentive for
entrepreneurs to inaugurate or withdraw firrtls from the industry.
Firms will move into or drop out of the .inqustry until
expectations of profits and losses have been roughly eliminated or
until it is no longer possible for anyone to better his position by
moving into or out of the industry in question. Under pure
competition, this equilibrium will be reached when price is almost
equal to the lowest cost on the typical firm's total unit cost curve.
Under competition, the price cannot stay higher for long; and
withdrawal of firms will keep it from staying lower for a long period.
Survival of the Fittest
At any given time, there may be firms of varying sizes and
efficiency in an industry, possibly some making profits and others
incurring losses. Ellt so long as industry is open for anyone to enter
freely, an excess of price over the attainable average total costs will
encourage the entry of new firms. As such new firms move in, they
compete with existing firms and the most inefficient firms are
eliminated. In the long-run, therefore, only those firms will remain in
the industry, which have the lowest average total costs, as low as
those, which would be incurred by new enterprises in optimal scale
adjustments. If a long-run equilibrium position is linally attained,
there might still be many differences between firms but the lowest
average total costs of all firms would be the same. For instance,
some entrcpr.eneurs may be more efficient than others, some firms
may be located near markets and may be paying higher rents
whereas others are more distant and may be paying lower rents.
Again, some firms may be small with close personal supervision and
hence with greater efficiency whereas others may be large and with
mass production methods, In view of these differences, the firms
may not be having identical or similar cost curves. Still, each firm
must produce at an average cost as low as that of its competitors.
In other words, though there may be differences between firms,
these may be balanced by balancing advantages and disadvantages
giving rise to uniformity of minimum average total costs.
To illustrate, two manufacturers of cotton textiles may be
differently located; one may qave the advantage of nearness to
buyers but the disadvantage of higher rent. The other may be
located away from the buyers and as such may have the advantage
of lower rent but the disadvantage of higher transport costs. Here
the advantages and disadvantages may balance so that the two
firms have the same lowest average costs. Another example is that
of one firm having a more efficient manager than the other. Here
the efficient firm may have the advantage of higher productivity but
disadvantage of higher salary payments as' compared to the less
efficient firm. On balance, the two firms may have the same lowest
average costs.
In an industry adjustments towards long-run equilibrium do
not necessarily I take place smoothly. In fact, too many firms may
enter· a profitable industry. Thus, by the time they are turning out
finished products, market price may drop below costs. As a result,
firms may start withdrawing from the industry so much so that too
many firms withdraw with opposite effects. This is most likely to
occur where initial investments are relatively small or where given
fixed equipment can be' utilised in other industries. This is because
these conditions facilitate quick entry as well as withdrawal.
Agriculture provides an example of this type where the same fixed
assets can be utilised alternatively as, for example, either for
producing wheat or cotton, jute or rice.
Restrictions on Firm's Entry and Withdrawal
Free entry'of new firms is usually restricted through
Financial or technical barriers to entry into costly
and complex technological processes;
Government intervention and legal restrictions; and
Collusion among producers on prices, market shares,
tendering, etc.
Until 1991, the Indian economy was regulated by numerous
Government decisions on wages, price, size and scope of
production, industrial relations, foreign exchange, etc. Due to these
Government regulations, hardly any industry was free to decide on
its scale and methods of production, wage policies retrenchment,
equipment etc. Again, the Indian industrialist operated in a
completely sheltered market. He was protected against external
(foreign) competition by import and exchange controls. The
requirement of a licence before starting a large-scale unit further
protected him from internal (Indian) competition. Thus, entry and
withdrawal of firms was highly restricted in Indian conditions.
However, now the entrepreneurs are free to decide about the
industry they want to establish and its size except in a limited
number of industries, which are still subject to Government
regulation.
VARIANTS OF PERFECT COMPETITION
1. Effective or Workable Competition
Competition among the sellers, even though it may not be perfect,
can be regarded as effective if it offers real alternatives to
consumers that are sufficient to compel sellers to vary quality,
service and price substantially with a view to attract buyers.
The prerequisites of effective competition are as follows:
Ready substitution of one product for another.
General availability of essential information about a1ternati (its
significance lies in that buyers cannot influence the behaviour
of the sellers unless alternatives are known)
Presence of several sellers, each of them possessing the
capacity to survive and grow
Preservation of conditions which keep alive the basis or
potential competition from others
Substantial independence of action that is each selIn must be
able and willing constantly to reconsider his policy and to
modify it in the light or changing conditions of demand and
supply.
Effective competition cannot be expected in fields where sellers
are so few ill number, capital requirements so large, and the
pressure of fixed charges so strong that price warfare, or its threat
of will lead almost inevitably to collusive (deceitful) understanding
among the members of the trade of. the industry concerned. In
brief, competition is said to be effective whenever it operates over
time to provide alternatives to buyers and to afford them
substantial protection against exploitation. The concept of effective
competition, though less definite, is more realistic and relevant
than that of perfect competition.
2. Potential Competition
Potential competition may restrain producers from overcharging
those to whom they sell or from underpaying those from whom they
buy. The essential precondition for potential competition is the
preservation of freedom to enter or to leave the market. The
exclusive ownership of scarce resource, the heavy investment
required for entry into many fields, the fixed character of much of
the existing equipment, high costs of transportation, restrictive
tariffs, exclusive franchises, and patent rights constantly operate to
destroy the hasis of potential' competition. Science, invention and
the development of technology constantly operate to keep this
potentiality alive. Potential competition, insofar as its basis
continues, may compensate in part for the shortcomings of the, lack
of perfect competition.
Key Lessons of Perfect Competition of Managers
The key lessons of perfect competition or competitiveness for
managers in highly competitive market environment are as under:
It is important to enter a growing market as far ahead of the
competitors as possiblc. Smart managers should take
advantage well before the competitors enter the market when
supply is low and price is high. This requires entrepreneurial
skill to take a risk.
A firm, which is earning an economic profit (distinguished from
norm.al profit), cannot afford to be complacent or unprepared
for increasing cOlllpditioll hccausc cconomic profit will
eventually attract new entrants encouraging mare production
and enhancing supply, drive prices down down and reduce
economic profits. Here, it is impossible for a firm in a pcrkclly
compclitive market to compete based on product
differentiation. Therefore, the only way that it can earn or
maintain profit in the face of added supply and lower prices is
to keep its costs as low as possible. The lesson that one can
learn from understanding the perfectly competitive model is
that a firm is to be amongst the lowest cost producer to ensure
its survival.
PRICE AND OUTPUT DECISIONS UNDER MONOPOLY
Monopolistic market situation allows an individual seller or groups of
sellers, which arc acting as a unit, to exercise direct control over
price. Similarly, any such control on the part of buyers is called a
monopsonistic market situation. The monopo.listic and
monopsonistic market situations may be distinguished according to
the nature and extent of the deviation from the perfect competition.
A useful classification Can be: (i) monopoly and monopsony; (ii)
monopolistic competition; and (iii) oligopoly and oligopsony.
However, in this chapter, the discussion is confineclto monopoly
only.
Main Features of Monopoly
The essential features of monopoly are as follows:
Single seller: There is only one producer or firm of a
commodity in the market. This is because there remains no
distinction between an industry and a firm in a monopolistic
market. Here, the firm itself becomes the industry and thus
has full control over supply of the commodity. The monopolist
may be an individual, a firm or a group of firms or even
Government itself. There are many buyers of the commodities
produced by a monopolist, against a single seller.
No close substitutes of the commodity: The commodity
sold by the monopolist has no close substitutes. This implies
that the cross-elasticity of demand between the monopofist'"s
product or commodity is very low. Though substitutes of
products are· available but they are not close substitutes.
Difficult entry of a new firm: The monopolist controls the
market situation in such a way that it every new firm finds it
to be very difficult to enter the monopoly market and also to
compete with the monopolistic firm to produce either the
homogeneous or identical product. This makes the
monopolist, the price maker himself.
Negatively sloped demand curve: The demand curve of a
monopolist firm is negatively sloped, which means that a
monopolist can sell more products only at a lower price and
not at a higher price.
Keeping in mind the features of a monopoly, it can be said
that the monopolist is in a position to set the price himself and also
enjoys the market power.
The strength of a monopolist lies in his power to raise his
prices without the fear to loose his customers. However, the extent
to which he can raise depends on the elasticity of demand for his
particular product. This, in turn, depends on the extent to which
substitutes for his products are available. In most cases, there is an
endless series of closely competing substitutes. Therefore, exclusive
monopolies like railways or telephones also consider the possible
competition by alternative services. In this case, any increase in the
rates by railways, may lead to their substitution by motor transport
and of telephone calls by telegrams. In fact, it is very difficult to
draw a line between what is and what is not a monopoly. The truth
is that there is a continuous shift between competition and
monopoly, just as there is between light and darkness, or between
health and sickness.
Even in those industries, which appear to be monopolised at
any time, monopoly has a constant tendency to break down. First,
there have been shifts in consumer demand. Secondly, inventions
may develop numerous substitutes for the monopolist's product.
Thirdly, the monopolist may suffer from lack of stimulus to
efficiency provided by competition. He may not devote attention to
the improvement of his product. In addition, new competitors may
arise to fill the gap. Finally, the Government may intervene.
Causes of Monopoly
The government may grant a licence to any particular person
or persons for operating public utilities such as gas company,
an electricity undertaking, etc. In public utility services,
economies of scale are so prominent that it seems almost
unbelievable to have several firms performing the same
service again. In such a case, the Government may reserve the
right of foreign trade related to any commodity for itself or may
give the right to any other person. In all these cases, the
statutory grant of special privileges by the State creates the
condition of monopoly.
The use of certain scarce raw materials, patent rights, special
methods of production or specialised skill, might also give a
producer monopoly power. For example, Hoechst, held a
monopoly for some time in oral medicines for diabetes because
they were the first to find out the methods of reducing blood
sugar by an oral dose.
Monopoly also arises where the minimum efficient scale of
operations is very large. For example, it is so for making some
chemicals In fact, monopoly tends to arise in industries
characterised by decreasing long-run costs.
Ignorance, laziness and injustice on the part of the buyers may
create monopoly in favour of a particular producer.
Revenue and Cost of Monopolists
The revenue and costs of monopolistic firm can be understood with
the following explanations:
Average Revenue: By raising the prices slightly, a monopolist
can sell less, but there will be some buyers of his product. He
can increase his sales only by reducing his price. In this
situation, his average revenue (demand curve) will slope
downwards to the right. Such a change in AR curve shows that
larger quantities can be sold at lower prices whereas smaller
quantities can be sold at higher prices.
Marginal Revenue and the Sale Value of the Incremental
Output: In the market situation of pure competition, both
marginal revenue and the sale value of the incremental output
are identical. But this is not in the case of monopolly. A
monopolist needs to reduce his prices, to sell additional units
of his commodities. This reduction in price will apply both to
old as well as· new customers. Lei us assume that a shirt
manufacturer retails his shirts at Rs. 40 per unit. Total sales are
1,000 shirts. To sell 1,100 shirts, he reduces his price to Rs. 38.
The sale value of the additional output will be Rs. 3,800 where
as the marginal revenue will be Rs. 1,800 only. Thus, under
monopoly conditions marginal revenue will always be less than
the sale value of the additional output. However, after a stage,
the marginal revenue may even become negative.
Adjustments under Monopoly
A firm under this market situation can choose to sell many units at a
lower price or fewer units at a higher price. For maximisation of
profit or minirnisation of loss, a monopolistic firm would minimise or
reduce the use of inputs and outputs to the level at which the
marginal revenue equals the marginal cost. However, there is a
significant difference between a purely competitive firm and a
monopoly. The difference lies in the fact that for a purely
competitive firm, marginal revenue equals the average revenue
while in a monopolistic firm, marginal revenue is less than the
average revenue. Therefore, a monopolist in purely competitive firm
can only produce up to the point where average revenue equals the
marginal cost. This can be understood with the help of the Figures
4.24 and 4.25 are givefl below:
With reference to these figures, under perfect competition,
output would be OQP (Figure 4.24) as MR curve or the horizontal AR
curve, interesects the MC curve at point Ep. Butunder monopoly,
MR = MC at a point Em corresponding to output OQm (Figure 4.24),
which is less than OQP. Under monopoly, the MR curve is not equal
to AR curve, but lies below it. Thus, the monopolist's output will be
lower, and the use of productive services is also less than it that in
the case of pure comprtition, where adjustments are made to suit
consumers' preferences. In other words, in ll1uximising the profits,
the monopolist does not take into consideration the interests of the
consumers and the resource owners. It is the total profit that guides
the monopolist in his price and output policy. The total profit is
calculated by multiplying the profit per unit by the number of units
sold. By using the process of trial uilci error with di fferent levels of
price and output, a monopolist fixes a price-output combination
that yields him the highest total profit.
Disadvantages of Monopoly
Under monopolistic condition, a monopolist exercises the
market power by restricting supplies. By doing so, he is
likely to become richer than he' would have been if he had
no market power. He also docs this even at the expense of
those who consume his products.
In a monopolistic situation, a consumer choice is restricted.
A consumer depends on the monopolist’s decisions on the
mutters related to price, and the amount the direction of
research and development in the industry, the services
offered, etc.
Under monopoly, there is a complete absence of
competition, which means that there will be no prcssure on
the monopolist firm to be economical and to keep its costs
down. By keeping its prices higher, a monopolist tends to
wastc its cost or production. This is a biggest drawback of a
monopolistic tinn.
By exercising the monopolistic power, a monopolist is likely
to misalloeate the resources from society's point of view. As
the monopolist restricts output, his output becomes too
small. He employs too little of society's resources. As
aresult, of this, too much of these resources are used into
the production of the goods with low consumer preferences.
Thus, resources are mislilioclited or wasted.
A firm enjoying monopoly position in a strategic sector is a
big a risk for an economy. For example, any failure related
to the power engineering facilities of a firm, is a hindrance
for an economy, In one BHEL, a firm is full of'risk, as any
natural or man made causes, which may lead to slowdown
or stoppage of production is a severe setback to the
economy.
Long-run Considerations and Price Policies of a Monopolist
In deciding the current price policy, monopolists commonly take into
account' some long-run considerations, which may lead to a more
moderate price policy than would be followed by a firm taking into
account short-term factors only:
Price elasticity of demand: The ability to increase profits
by restricting supplies is the criterion of monopoly or market
power. In this respect, the more elastic the demalld for the
products, the weaker is the position or Ihc monopolist. But
there will always be a price, above which the demand is so
elastic that it will not cost anything to the monopolist to incur
the loss related to less sales by raising the prices higher. In
the long-run, consumer receptiveness to price may be much
greater than in the short run. Thererore, an intelligent
monopolist must consider this factor before exercising
monopolistic power. If a monopolist's prices are held at high
lewis, consumers may stop utilising that commodity. This will
result in decreased consumption. On the other hand, if the
prices remain lower over extended periods, the consumers
will get used to that product, more people will be interested in
it and those already consuming it may increase their
consumption as well.
Potential competition from new tirms: If a firm is very well
established, exercise strong and exclusive control over
essential raw materials, possess indispensable patents, and
licensing regulations, it may pursue extremely high price
policies without great concern for the competition that these
prices may attract. If, on the other hand, its controls over firms
are not so strong, it depends primarily on unfair competition
and uncclillin manipulation, then the fear of potential
competition may become an important factor to modify the
monopolist's policies.
State of public opinion: Public hostility to unfair practices
and exploitHI ion may appear in many forms like consumer
boycotts, both formal and informal, and legal restrictions and
controls. Hostile public opinion is wry important to be ignored
irrespective of the form in which it is. Many times it may
temper the behaviour of the monopolist seeking to maximise
his profits.
If a monopolist is cautious, he needs not to work against public
interest. This is because the monopolists, being big concerns can
enjoy the economies of largescale production. They are in a better
position to maintain regular and satisfactory supplies. They can also
avail the benefits of large-scale buying ar1d selling. In fact they can
operate a better level of efficiency. If they restrain themselves and
do not exploit the consumers, they may not only build up a good
image in the market. By doing this, they are also likely to avoid
potential competition and Government interference.
Differenco between Monopoly and Pure Competition
The salient points of difference between monopoly and perfect
competition are as follows:
Under perfect competition, there are a large number of
sellers
or firms whercns in monopoly, there is a single seller or firm.
Under perfect competition, the individual seller has no control
over the market pries whereas under monopoly, the seller is
in a position to nlllnipulnte the output in order to control the
prices.
Under perfect competition, the commodity produced by the
firms is homogeneous in nature whereas there is no close
substitute of the commodities produced by monopoly.
Under perfect competition, a firm is a price taker and not a
price maker whereas in monopoly a firm is a price maker.
Under perfect competition, there is free entry and exit of the
firms in the market whereas monopoly this is not so.
Under perfect competition, firms get only normal profits in
the
long period whercas in monopoly, there is the possibility of
super-normal profits to take place.
Under perfect competition, there is no possibility of price
discrimination whereas in monopoly, price discrimination is
possible.
MONOPSONY
It is a market situation in which there is single buyer to buy the
commodities but there may be many sellers to sell the identical or
homogeneous commodity.
Features of Monopsony
The essential features of monopsony are as follows:
There is only onc buyer or the goods or services.
Rivalry from buyers, who offer the close substitutes of the
product, is so remote to make it insignificant.
As a result, the buyer is in a position to determine the price,
which he pays for the goods or commodities.
Actual causes closely approximating monopsony are rare.
An, example, approximating monopsony is that of Indian Railways
in relation to the wagon industry. Monopsony may also arise
where resources are immobile. If for reason, workers are unable
to move to other localities or other firms within same area, their
existing employer has, in effect, a inonopsony position over them.
Costs of Monopsonists
The monopsonist must choose between paying higher wages that
will enable him to employ more workers or limiting his working force
to the analler number workers, who can be employed at lower
wages. This means that when additional worker is added to the
labour force, an employer has to bear both, I wage of the new
worker and also the total increase in the wages to be paid to t old
employees at the new rate. Thus, in monopsonistic market situation,
margir expenditure of each input level exceeds average expenditure
(Table I aild Figu 4.26). Suppose a tailor employs six workers at Rs.
500 per month. To have I additional worker, he must pay Rs. 550
per month to each worker. If he employs the seventh worker, his
total costs, thus, will increase by Rs. 850. To represent the position
graphically, two curves are needed, one to show the average
expenditur and the other to show the marginal expenditure. The
marginal expenditure (ME) is consistently higher than the average
expenditure (AE) and the slope of thl marginal expenditure cutve is
steeper than that of the average expenditure curve.
The following Table 4.4 shows the cost of a monopsonistic firm
hiring workers.

Price Discrimination
Price discrimination, may be defined as the practice by a seller of
charging different prices to thL: samc buyer or to different buyers
for the same commodity or service without corresponding difference
in the cost. It is also known as differential pricing. Differences in
rates are somewhat related to the in costs. For example, it may cost
less to serve one class of customers than another to sell in large
quantities than in smaller lots. !frates or prices are proportional to
cost, some buyers will pay more and others less, but this will not
take place in price discrimination. In such a situation, charging
uniform price will amount to discriminat ion. There arc three classes
of price discrimination, which are as follows:
First-degree discrimination: The seller charges, the same
buyer a different price, for euch unit bought. For exumple,
prices that are determined by bargaining with individual
customers or prices, which are quoted for tenders floated by
government authorities.
Second degree discrimination: The seller charges different
prices for blocks of units, instead of, for individual units. For
example, different rates charged by an ekctrieity undertaking
for light and fan, for domestic power and for industrial use.
Third degree discrimination: The seller segregates buyers
according to income, geographic location, individual tastes,
kinds of uses for the product, etc. and charges different prices
to each group or market despite of charging equivalent costs
from them. If the demand elasticities among different buyers
are unequal, it will be profitable for the seller to put the buyer
into separate classes according to elasticity and thereby, to
charge each class a different price. It is also referred as
market segmentation and involves dividing the total market
into homogeneous sub-groups according to some economic
criterion, usually the demand elasticity.
Conditions for Price Discrimination
The conditions for price discrimination arc as follows:
Multiple demand elasticities: There must be difference in
demand elasticities among buyers due to differences in
income, location, available alternatives, tastes, etc.
Market segmentation: The seller must be able to divide the
total market by separating the buyers into groups or sub-
markets according to elasticity.
Market sealing: The seller must be able to prevent any
significant resale of goods from the lower to the higher price
sub-market. Any resale by buyers among the sub-markets will,
beyond minimum critical levels, neutralisc the effect of
different prices.
Market Segmentation
Haynes, Mote and Paul have identified certain criteria according to
which market segmentation is practised. These criteria are given
below:
Segmentation by income and wealth: This can be
understood by considering an example, in which the doctors
separate patients with high incomes from patients with low
incomes. The fact that doctor's treatment is a direct personal
service prevents its resale.
Segmentation by quantity of purchase: Traders often
distinguish between large and small purchasers, offering
quantity discounts to large purchasers. The big buyers because
of their bargaining power are able to extract special quantity
discounts. However, if the quantity discounts are in proportion
to the marginal costs of selling to big and small buyers, they
will not be counted in price discrimination.
Segmentation by social or professional status of the
customer: Special prices may be quoted to Central and State
Governments or to Universities. Students are given
concessions in cinema tickets, railway fare and bus travel.
Profes'sional journals usually carry lower student subscription
rates. Faculty members or teachers are also sometimes offered
books at special discounts.
Segmentation by geography: This can be understood by
considering an example. For example, business houses, which
are sold abroad at prices, lower than the domestic price.
Segmentation by time of purchase: Reduced rates are
often quoted during festival seasons such as dussehra, diwali,
etc. off-season discounts are also popuinr in case of fans,
refrigerators, etc.
Segmentation by preferences for brand names and
other sales promotion devices: Some firms sell the same
type of product under different branp names at, different
prices. In this case, ignorance on the part of consumer
regarding similarity in the quality of products prevents a large-
scale of customcrs to shift from one brand to another. Market
segmentation also ensures, the manufactures, a certain degree
of flexibility in pricing. Apart from this is also to be ensured
that it should remain present in every segment of market. For
example, Hindustan Lever supplies liril to satisfy the top-end of
Ihe market, lifebuoy to the lowest end and lux to the middle-
end.
Objectives
The objectives of pricc discrimination are as follows:
To adjust the consumer's surplus in such a way that it accrues
to the producer and not to the consumer.
To dispose of occasional or irregula surpluses.
To develop a new market.
To make the maximum and proper use of the unutilised
capacity.
To earn monopoly profits.
To enter into or retain report markets.
To destroy or to forestall competition or to make the
competition amenable to Ihc wishes of the seller adopting
price discrimination. It may be called predatory or
discriminatory competition. The test of perdition of intent.
To raise the future sales. Quoting lower rates in the present
develop in future a taste for the similar commodities
producecl by the same manufacturer. For example, Reader's
Digest sells children's edition at lower rates. This develops the
taste of children towards the magazine and they are expected
to continue purchasing it even when they become adults.
Single Monopoly Price Vs. Price Discrimination
To examine the policy of price discrimination, is more useful rather
than to charge a single monopoly price. This can be done in
following ways:
First of all, a discriminating monopolist can increase his profits
by charging different prices to different buyers or groups of
buyers rather than to charge a single price to all the buyers.
Secondly, the policy of price discrimination is in the interests
of the consumers as well. Bigger' output is made available to
a large number of customers. This is of special significance in
the case of public utility services. The larger the consumption
of these services, the greater is the economic welfare.
Moreover, the consumers may be charged according to their
ability to pay, which is quite fair and reasonable.
Finally, the policy of price discrimination enables better
utilisation of capacity, preventing waste of social resources.
This can be understood with the help of following Table 4.5.
Table 4.5: Costs, Prices and Sales of a Monopolist
Price Sales Total Cost(Rs.) (Rs.) (Rs.)
9.00 100 1,4008.00 200 1,7507.00 300 2,0506.00 400 - 2,3005.00 500 2,5004.00 700 3,0003.00 1,000 3,4002.50 1,400 4,1002.00 2,000 5,0001.50 2,800 6,4001.00 3,600 8,000
The above Table gives the number of units, a monopolist can sell
at various prices and the total cost involved in producing them.
Answer the following questions related to the table.
How much should the monopolist prodllce find what price
should be charge, if' he sells his entire output at a single
price? How much profit will he earn?
How much should be produced if the monopolist fixes II
discriminatory price, dividing his customers into separate
groups according to their ability to pay and charging
maximum prices from each group? How much will be the
profit, which the monopolist will earn?
Will the monopolist be better off if he charges a single price or
discriminating prices and by how much?
Will it be in the interest of the consumers if the monopolist
charges discriminating prices? Explain.
Will the policy of price discrimination enable better utilisation of
capacity' as compared to a single price?
How much maximum profit would the monopolist earn if he is
allowed price discrimination but cannot charge more than
RS.2? Would it make any difference to capacity utilisation and
availability of supply the consumers?
Solution
If the monopolist sells the output at a single price, he will choose
that price, which will yield the largest profit, He will, therefore,
produce 400 units and charge Rs. 6. The maximum profit he will
earn is Rs. 100. This will be clear from the following Table 4.6:
Table 4.6: Monopolist Selling at a Single Price
If the monopolist discriminates, dividing his customers into
groups according to their ability to pay and charging different
prices from each group, the results would be as given in the
following Table 4.7:

were in Table 4.5. But the monopolist divides his customers into
separate groups and charges different prices from each group. The
basis of dividing the customers is as follows:
When price is Rs. 9 per unit, 100 units are sold, when the price is
Rs. 8 per unit, 200 units are sold. This means that 100 units can be
sold for Rs. 9 per unit and another 100 for Rs. 9 per unit. Similarly,
by charging Rs. 7 per unit, the monopolist can sell another 100
units. In this way, other categories have also been formed as shown
in column 3. Column 4 gives revenue from each category, which is
calculated by multiplying the figures of column 3 with the
corresponding figures of column 1. Column 5 gives tot21 revenue
obtained by selling goods to various categories of the customers.
Column 6 gives total cost and column 7 gives profit or loss.
In this situation, a. discriminating monopolist will also seek the
maximum profit, which cen be obtained by creating a category of
customers and charging Rs. 9 from those on the top class and Rs. 2
from those in the bottom of the category. With such a differential
price structure, the monopolist will sell 2,000 units and earn a
maximum profit of Rs. 2,400.
The monopolist will be better off by Rs. 2,300 by charging the
discriminating prices he will earn as much as Rs. 2,400 as
against a maximum of Rs. 100 by charging the single price of
Rs. 6.
The policy of discriminating prices is in the interest of the
customers as well. Larger output of 2,000 units, is beneficial
to a larger number of customers. Moreover, each customer is
charged according to his ability to pay. Therefore, the policy is
fair as well as reasonable.
The policy of price discrimination will enable better utilisation of
capacity. Assuming the monopolist has a capacity to produce
3,600 units, he would operate at a level of 2,000 units which
is much' closer to full capacity as against the level of 400
units, where the monopolist will operate if he chmges the
single price of Rs. 6.
If the maximum price that can be charged is Rs. 2, the
monopolist will earn a maximum profit of Rs. 200 by
practising price discrimination as shown in the following Table
4.8.

But capacity utilisation and availability of supplies will remain
unaltered.
APPENDIX 1
Price Discrimination - Diagrammatic Exposition
A diagrammatic exposition of the theory of price discrimination is
shown below. Figure 4.27 presents the diagram of price
discriminate adopted in traditional economic theory.
Let us suppose that the market for a product consists of two
segments, one with a more elastic demand curve than the other D1
shows the demand in the more elastic segment and D2 shows the
demand in the less elastic segment. MR. and MR2 represent the
corresponding marginal revenue curves. The total marginal,
revenue cllrve MRT adds together the quantities in both market
segments at each marginal revenue. Thus MRT = MR1+ MR2. On the
cost side, the diagram shows a marginal cost curve MC, which alone
is relevant. It may be noted that only one I marginal cost curw
exists because it makes no difference from the cost point of view
whethcr the products sell in market segment 1 or market segment
2, since the product is the same.
As usual, profit will be maximised where marginal revenue is
cquallo marginal cost. Such equality exists at point E in the diagram
where 'the total margimil revel1lie curve (MRT) intersects the
ll1argin::d cost curve (MC). A horizontal line drawn from this point of
intersection E, back to the Y-axis cuts the two marginal revenue
curves MR, and MR2 at points F and G respectively. These roints
determine the quantities to be sold in each market segment and the
prices which shall prevail in each market segment. For this purpose
one should first draw a perpendicular line frolll point F on X-axis,
showing OX, as the quantity in market segment 1. Agai by
extending this perpendicular line upward to meet the demand curve
0" one gets p. as the price for this market segment. Similarly, frol1l
point drawing the perpendicular to X-axis and thereafter extending
it to the demand c.urve D2, we get OX2 as·the quantity to be sold
and P2 as the price to be charged in market segment 2. The
quantity sold in market segment 1 (OXI) plus the quantity sold in
market segment 2 (OX2) exhausts the total quantity OQ (i.e., OX1 +
OX2 = OQ). Further, the price PI is lower than the price P2 thus
indicating that the price in the more elastic market segment (DI)
shall be less than the price in the less elastic market segment (D2).
The two prices PI and P2 provide different margins of contribution to
profit. It should also be noted that (he solution equates the marginal
revenue in each segment (i.e., X2G = X.F) besides equating the
total marginal revenue to marginal cost at point F. If MR. was
greater than MR2, the firm could increase profits by transferring
units of product from market segment 2 to-market segments I. This
is an illustration of the equi-marginal principle. If either MR1 or MR2
were greater than me, an expansion of output would be profitable.
Optimisation thus requires that MR1 = MR2 = Me.
APPENDIX 2
Measures of Monopoly Power
Several economistS have given different measures of monopoly
power. These are discussed below:
Lerner's measure: According to Lerner, the difference between
price dnd marginal cost, measures the gegree of monopoly power.
In other words, a seller's monopoly power depends upon his ability
to sell the commodity at a price above its marginal cost. A perfectly
competitive seller enjoys no monopoly power and in his case:
Price = Marginal cost (or P - MC = 0).
But as monopoly po~er emerges, P - MC becomes greater than zero and as the
power increases, the gap between price and MC increases. Thus, the degree or index
of monopoly power can be measured as being equal to:
P =MC
P
For instance, if price is Rs. 20 and marginal cost is Rs.12, the
degree of monopoly power is
20-12= 0.4
20
Lerner also relates the monopoly power to price-elasticity of
demand. Accordingly, higher the price-elasticity of demand, smaller
is the degree of monopoly power. Also, the degree of monopoly
power is the reciprocal of the price-elasticity of demand. That is, if
elasticity is 2, the degree of monopoly is V*.
Bain's measure: Bain measures degree of monopoly power in
terms of supernormal profits. The supernormal profits are
equal to (P - AC) Q, where P = Price, AC = average cost, and Q
is output.
Rotbscbilds' measure: Rothschilos defines degree of monopoly
power, in terms of the proportion of the slopes of the firms
and industry demand curves, i.e.,
degree of monopoly power
=
Slope of the firm’s demand curve
Slope of the industry’s demand
curve
Triffin's measure: Trimn measures degree of monopoly
power in terms of price cross-elasticity of demand. Price cross-
elasticity of demand means the extent of substitution
between the products of two firms when one of them changes
the price of its product. If cross-elasticity of demand is zero,
this implies that the firm has an absolute monopoly power.

LESSON - 5
PROFIT
MEANNING
Profit means different things to different people. The word ‘profit’
has different meanings to business, accountants, tax collectors
workers and economists. In a general sense, profit is regarded as
income of the equity shareholders. Similarly wages getting
accumulated of a labor, rent accruing to the owners of any land or
building and interest getting due to the investors of capital of a
business, are a kind of profit for labours, land owners and investors.
To an account, profit means the excess of revenue over all paid out
costs including both manufacturing and overhead expenses. It is
much similar to net profit. In accountancy, profit or business income
means profit of a business including its non allowance expenses. In
economic, Profit is called pure profit, which may be defined as a
residual left after all contractual costs have been met, including the
transfer costs of management insurable risks, depreciation and
payment to shareholders, sufficient to maintain investment at its
current level. Therefore pure profit can be calculated with the help
of following formula.
Pure Profit = Total Revenue - (explicit costs + implicit costs).
Economic or pure profit also makes provision for insurable risks,
depreciation and necessary minimum payments to shareholders to
prevent them from withdrawing their capital. Pure profit is
considered to be a short – term phenomenon. It does not exist in the
long run, especially under perfectly conditions. Because of this, they
may either be positive or negative for a single firm in a single year.
The concept of economic profit differs from that of accounting
profit Economic profit takes into account also the implicit or imputed
costs. The implicit cost is also called opportunity cost. If an
entrepreneur uses his labor in his own business, he foregoes his
income or salary, which he might have earned by working as a
manager in another firm. Similarly, by using assets like and building
and his own business, he foregoes the market rent, which might
have earned otherwise. All these foregone incomes such as interest,
salary and rent, are called opportunity costs or transfer costs.
Accounting profit does not consider the opportunity cost.
THEORIES OF PROFIT AND SOURCES OF PROFIT
There are various theories of profit, given by several economists,
which are as follows:
Walker’s Theory of: Profit as Rent of Ability
This theory is pounded by F.A. Walker. According to F.A. Walker,
“Profit is the rent of exceptional abilities that an entrepreneur may
possess over others. Rent is the difference between the yields of the
least and the most efficient entrepreneurs. In formulating this
theory, Walker assumed a state of perfect completion in which all
firms are presumed to possess equal managerial ability each firm
receives only the wages which in Walker view forms no part of pure
profit. Hen considered wages of management as ordinary wages
thus, under perfectly competitive conditions, there would be no pure
profit and all firms would earn only wages, which is known as
normal profit.
Clark’s Dynamic Theory
This theory is propounded by J.B. Clark According to him, “profits
arise in a dynamic economy and not in static economy.”
A static economy and the firms under it, has the following features:
Absolute freedom of completion
Population and capital are stationary
Production process remains unchanged over time.
Homogeneous goods
Factors of production enjoy freedom of mobility but do not
move because their marginal product in very industry is the
same.
There is no uncertainly and risk. If there is any risk, It is
insurable
All firms make only normal profit
A dynamic economy is characterized by the following features:
Increase in population
Increase In capital
Improvement in production techniques.
Changes in the forms of business organization
The major function of entrepreneurs or managers in a
dynamic economic is to take the advantage of all of the above
features and promote their business by expanding their sales and
reducing their costs of production.
According to J.B. Clark, “Profit is an elusive sum, which
entrepreneurs grasp but cannot hold. It slips through their fingers
and bestows itself on all members of the society”. This result in rise
in demand for factors pf production and therefore rises in factor
prices and subsequent rise in the cost of production. On the other
hand, because of rise in cost of production and the subsequent fall
in selling price of the commodities, the profit disappears.
Disappearing of profit does not mean that profit arise in dynamic
economy once only, but it means that the managers take the
advantage of the changes taking place in the economy and thereby
making profits.
Howley’s Risk Theory of Profit
The risk theory pf profit is propounded by F.B. Hawley’s in 1893.
Risk in business may arise due to obsolescence of a product, sudden
fall in prices, non-availability of certain materials, introduction of a
better substitute by a competitor and risks due to fire, war, etc.
Hawley’s considered risk taking as an inevitable element of
production and those who take risk are more likely to earn larger
profits. According to Hawley, Profit is simply the price paid by
society assuming business risks. In his opinion in excess of
predetermined risk. They also look for a return in excess of the wags
for bearing risk is that the assumption of risk is irrelevant and gives
to trouble and anxiety. According to Hawley, Profit consists of two
part, which are as follows:-
One Part represents compensation for actual or average loss
supplementing the various classes of risk.
The other part represents a penalty to suffer the
consequences of being exposed to risk in the entrepreneurial
activities.
Hawley believed that profits arise from factor ownership as
long as ownership involves risk. According to Hawle’y an
entrepreneur has to assume risk to earn more and more profit. In
case of absence of risks, an entrepreneur would cease to be an
entrepreneur and would not receive any profit. In this theory, profits
arise out of uninsured risks. The amount of reward cannot be
determined, until the uncertainly ends with the sale of entrepreneur
products profit in his opinion is a residue and therefore. Hawley
theory is also called a residential theory of Profit.
Knight’s Theory of Profit
This theory of profit is propounded by frank H. Knight who treated
profit as a residual return because of uncertainly, and not because
of risk bearing. Knight made a distinction between risk and
uncertainly by dividing risk into two categories, calculable and non-
calculable risks. They are explained as below:-
Calculable risks are those, the prodigality of occurrence of
which van be calculated on the basis of available data. For
example risk, due to fire theft accidents etc. are calculable
and such risks are insurable.
Incalculable risks are those the probability of occurrence of
which cannot be calculated. For Instance there may be a
certain elements of cost, which may not be accurately
calculable and the strategies of the competitors may not be
precisely assessable. These risk are called includable risks.
The risk element of such incalculable costs is also insurable.
It is in the area of uncertainly which makes decision-making a
crucial function for an entrepreneur. If his decisions prove to be
right, the entrepreneur makes profit, Thus according to knight profit
arises from the decisions taken and implemented under the
conditions of uncertainly. The profits may arises as a result of
decision related to the state of market such as decision, which
increase the degree of monopoly, decisions regarding holding of
stocks that give rise to windfall gains and the decisions taken to
introduce new techniques or innovations.
Schumpeter’s Innovation Theory of Profit
Joseph A. Schumpeter developed the innovation theory of Profit.
According to Joseph A. Schumpeter, factors like emergence of
Interest and profits, recurrence of trade cycles only supplement the
distinct process of economic development to explain the
phenomenon of economic development and profit, Schumpeter
starts from the state of a stationary equilibrium, which is
characterized by the equilibrium in all the spheres. Under these
conditions stationary equilibrium, the total receipts from the
business are exactly equal to the cost. This means that there will be
no profit. The profit can be earned only by introducing innovations in
manufacturing technique and the methods of supplying the goods
innovations may include the following activities.
Introduction of a new commodity or a new quality of goods.
Introduction of a new method of production.
Introduction of a new market.
Finding the new sources of raw material
Organizing the industry in an innovative manner with the new
techniques.
The factor prices tend to increase while the supply of factors
remains the same. As a result, cost of production increase. On the
other hand with other firms adopting innovations, supply of goods
and services increases resulting in a fall in their prices. Thus, on one
hand, cost per unit of output goes up and on the other revenue per
unit decrease. Finally, a stage comes when there is no difference
between costs and receipts. As a result there are no profits at all.
Here, economy has reached a state of equilibrium, but there is the
possibility of existence of profits. Such profits are in the nature of
Quasi-rent arising due to some special characteristics of productive
services. Furthermore, where profits arise due to factors such as
patents, trusts, etc. they will be in the nature of monopoly revenue
rather than entrepreneurial profits.
MONOPLOY PROFIT
Monopoly is a market situation in which there is a single seller of a
commodity without a close substitute. Monopoly may arise due to
economies of scale, sole ownership of raw materials, legal sanction,
protection, mergers and take–overs. A monopolist may earn pure
profit, which is also called monopoly profit in the case of a
monopoly, and maintain it in the long run by using its monopoly
powers. Monopoly powers are as follows:-
Powers to control supply and price.
Powers to prevent the entry of competitors by reducing the
prices.
The Monopoly powers help a monopoly firm to make pure
profit or monopoly profit. In such cases, monopoly is the source of
pure profit.
PROBLEMS IN PROFIT MEASURMENT
Accounting profit is the difference between all explicit costs and
economic profit or subtracting the difference of explicit and implicit
costs from revenue. Once profit is defined, it is easier for a firm to
measure the profit for a given period. The problems regarding the
measurement of profits are as follows:
The choice between the two concepts of profits, to be given
preference while using.
The determination of the various costs to be included in the
implicit and explicit costs.
The solutions to these problems are as follows:-
The use of a profit concept depends on the purpose of
measuring profit.
According concept of profit is used when the purpose is to
produce a profit figure for any of the following.
o The shareholders, to inform them of progress of the firm
o Financiers and creditors, who would be interested in the
firm’s progress
o The Managers to assess their own performance
o For computation of tax-liability.
To measure accounting profit for these purposes, necessary
revenue and cost data are, in general, obtained from the firm books
of account. It must, however, be noted that accounting profit may
present an overstatement or understand of actual profit, if it is
based on illogical allocation of revnues and costs to a given
accounting period.
On the other hand, if the objective is to measure true profit,
the concept of economic profit should be used. However true
profitability of any investment or business has been completely
done. But then the life of a business firm is unending therefore , true
profit can be measured only in terms of maximum amount that can
be distributed as dividends without harming the earning power of
the firm. This concept of business income is however, unattainable
and therefore, is of little practical use. It helps in income
measurement even from businessman point of view. From the
above discussion, it is clear that, for all practical purpose, profits
have to be measured on the basis of accounting concept. But
measuring even the accounting profit is not an easy task. The main
problem is to decide as to what should be and what should not be
included in the cost one might feel that profit and loss accounts and
balance sheet of the firms provide all the necessary data to
measure accounting profit there are, however three specific items of
cost and revenue which cause problems, such as depreciation,
capital gains and losses and current vs. historical costs. These
problems are related to measurement and may arise because of the
differences between economists and accountants view on these
items. The concept of current costs can be used understood from
the following description.
CURRENT vs. HISTORICAL COSTS
Meaning of Historical Costs
The income statements are prepared in terms of Historical costs and
not in terms of current price. Historical costs is the purchase price of
any asset ands includes the following.
Money spent in the acquisition of the asset including
transportation costs as well as the insurance cost.
Costs of installation such as wages paid for erection of
machinery and the amount spent on repairs at the time of
installation.
The reasons for using historical costs for calculating
depreciation rather than current costs are as follows:-
Historical costs produce more accurate measurement of
Income.
Historical costs are easily determined and more objective than
the values based on the use of current value on asset.
Accountants also record historical costs and consider them to
be more relevant, The accountants approach ignores certain
important changes in earnings and looses of the firms, which
may be any of the following:
o The value of asset pretended in the books of accounts is
understand at the time of inflation and overstated at the
time of deflation.
o Depreciation is understated during deflation. The
historical cost recorded in the books of account does not
reflect these changes in values of assets and profits.
This problem becomes more critical in case of
inventories and stock. The problem is how to evaluate
the value of inventory and the stocks.
Methods of Inventory Valuation
There are three popular methods of Inventory valuation, first in first
out (FIFO), last in fist out (LIFO) and weighted average cost (WAC)
Under FIFO method, material is taken out of stock for further
processing in the order in which they are acquired. The stocks,
therefore, appear in firms balance sheet at their actual cost price.
This method overstates profits at the time of rising prices.
Under LIFO method, the stock purchased most recently
become the costs of the raw material in the current production
under WAC method, the weighted average of the costs of materials
purchased at different prices and different point of time is calculated
to evaluate the inventory.
All these methods have their own disadvantages and do not
reflect the true profit of the business. So the problem of evaluating
inventories to yield a true profit remains unsolved.
Problems is Measuring Depreciation
Economists consider depreciation as capital consumption. For them,
there are two distinct ways of charging depreciation either by
assuming the value of depreciation of equipment to its opportunity
cost or to its replacement cost that will produce comparable
earning.
Opportunity cost of equipment is the most profitable alternate
use of that is foregone by putting it to its present use. The problem
is to measure the opportunity cost. One method of measuring the
opportunity cost. One method of measuring the opportunity cost, as
suggested by Joel Dean, is to measure the fall in value during a
year. By using this method cannot be applied when capital
equipment has no alternative use, like a hydropower project In such
cases, replacement cost is an appropriate measure of depreciation.
Under this method, the cost of the new asset and the residual value
of the old asset are taken as the depreciation of the asset. But
depreciation is recorded only at the time of replacement of an asset.
This method is used in public utility concerns like railway, electricity
companies. To accountants, depreciation is an allocation of under
expenditure over time. Such allocation or charging depreciation is
made under unrealistic assumptions such as stable prices and a
given rate of obsolescence. There are different methods of charging
depreciation, which are of utmost importance. The use of different
levels of profit reported by the accountants. It will be clearer after
considering the following example: Suppose a firm purchases a
machine for Rs. 10,000/- with an estimated life of 10 yrs. The firm
can apply any of the following four methods of charging
depreciation and the amount of depreciation for the given example
by using the different methods is as follows:
Straight Balance Method
Annuity Method
Sum-of the years digit approaches
Under the straight – line method, the amount of depreciation
remains the same throughout the life of the asset. Depreciation is
calculated according to a fixed percentage on the original cost. The
amount and rate of depreciation is calculated as under:
Amount of depreciation =Historical cost-residual value
Economic life of the asset
Rate of depreciation = Amount of depreciation x
100/Historical cost
Residual value is the realizable value of an asset at the end of
its economic life. Keeping in view the above example, the amount of
depreciation will be 10,000/10 = Rs. 1,000. It will be same for each
year. The rate of depreciation will be
1000 x 100/10,000 = 10
Under the reducing balance method, depreciation is charged
at a constant rate or percent of annually written down values of the
machine or any equipment. Assuming a depreciation rate of 20 per
cent, the amount of depreciation for different years will be
calculated as under :
Amount of Depreciation = Historical value x rate of depreciation
/100
But the amount of depreciation for the first year will be
deducted from the successive years. Therefore Rs. 2000 in the first
year, Rs. 1600 in the second year, Rs. 1280 in the third year, and so
on.
Under annuity method, rate of depreciation is fixed and is calculated
as under:-
d = (C + Cr )/n, where n is the total number of years of capital, C is
the total capital and r is the interest rate. The amount of
depreciation in this method is calculated with the help of annuity
table.
Finally under sum-or-the year’s digits approach, the total
years of equipment life are aggregated. Depreciation is then
charged at the rate of the ratio of the last years digits to the total of
the years. With respect to the given example, the aggregated years
of the equipment’s life’s will be 1+ 2 + 3 +... +10 = 55.
Depreciation in the 1st year will be 10,000 x 10/55 = Rs. 1818.18, in
the 2nd year it will be 1,000 x 9/55 = Rs. 1636.36 and in 3rd year it
will be 10,000 x 8/55 = Rs. 1454.54, and so on. These four methods
of depreciation results in different methods of depreciation and
subsequently different levels of profit.
TREATMENT OF CAPITAL GAINS AND LOSSES
Capital gains and losses arc regardea as windfalls. Fluctuation in the
stock market prices is one of the most common sources of wind
Ellis. According to Dean, capital losses are, greater than capital
gains in a progressive society. Many of the capital losses arc of
insurable nature and the excess becomes the capital gain.
Profit is also affeckd by the way capital gains and losses are
treated in accounting. According to Dean, "a sound accounting
policy to follow concerning windfalls is never to record them until
they are turned into cash by a purchase or sale of assets, since it is
never clear until then exactly how large they are". But, in practice,
some firms do not record capital gains until it is realised in money
terms, but they do write off capital losses from the current profit.
The use of different policies result in different profits. But an
economist is not concerned with the accounting practice or
principle, which is followed in recording the past events. An
economist is concerned mainly with what happens in future.
According to an economist, the management should be aware of the
approximate magnitude of such windfalls before they are accepted
by the accountants. This would be helpful in taking the right
decision with respect of those assets, which are affected by the use
of policies given by the economists.
PROFIT MAXIMISATION AS BUSINESS OBJECTIVE
Profit maximisation is the most important assumption, which helps
the economists to introduce the price and production theories. The
traditional economic theory assumes that the profit maximisation is
the only objective of business firms. According to this theory, profits
must be earned by business to provide for its own survival,
coverage of risks, growth and expansion. It is a necessary
motivating force and it is in terms of profits that the efficiency of a
business is measured. It forms the basis of conventional price
theory. Profit maximisation is regarded as the most reasonable and
analytically the most productive business objective.
The profit maximisation assumption in this theory helps in
predicting the behaviour of business firms and also the behaviour of
price and out pet under different market conditions. No alternative
hypothesis or assumption explains and predicts the behaviour of
firms better than the profit maximisation assumption. According to
this theory, total profit is the difference between total revenue and
total cost and is calculated as below:
TP = -TR – TC (1)
where,
TR = total revenue
TC = total cost
The total cost includes fixed cost and variable cost. The cost,
which remains same at different levels or output, is called fixed
cost. The sum of all t~ose costs, which vary directly with the level of
output, is called variable cost. In context with the profit
maximisation objective, the total profit or the difference between
total· cost and total profit is to be maximised. There are two
conditions that must be fulfilled for TR- TC to be maximum. These
conditions are divided into two categories, which are necessary or
first order condition and secondary or supplementary condition.
These conditions are explained as below:
The necessary or the first order condition states that marginal
revenue (MR) must be equal to marginal cost (MC). Marginal
revenue is the revenue obtained from the production and sale
of one additional unit of output. Marginal cost is the cost
arising due to the production of one additional unit of output.
The secondary or the second order condition states that the
first order condition must show the decreasing MR and rising
MC. The secondary condition is fulfilled only when both the MC
is rising as well as the MR is decreasing. This condition is
illustrated by point P2 in Figure 5.1.
Let us suppose that the total revenue and total cost functions
are, respectively given as below:
TR = TC = f (Q)
where, Q = quantity produced and sold.
Substituting total revenue and total cost functions In
Equation (I), profit function can be written as below:
TP = f(Q)TR - f(Q)TC (2)
With the help of equation (2), The first order condition and the
secondary. Condition can be understood easily.
First-order Condition
The first-order condition of maximising a function is that the first
derivative of the profit function must be equal to zero. By
differentiating the total profit function and equating it to zero, the
following equation is obtained:
aTP=
aTR-
aTC=0
(3)aQ aQ aQ
This condition holds only when
aTR=
aTC
aQ aQ
In Equation (3), the term aTR/aQ is the slope of the total
revenue curve, which is equal to the marginal revenue (MR).
Similarly, the term aTC/aQ is the slope of the total cost curve,
which is equal to the marginal cost (MC). Thus, the first-order
condition for profit maximisation can be stated as:
MR=MC
The first-order condition is also called necessary condition, as
it is so important that its non-fulfilment results in non-occurrence
of the secondary condition and thereby the profit maximisation
objective is not attained.
Second-order Condition
The second-order condition of profit maxirnisation requires that the
first order condition is satisfied under rising MC and decreasing MR.
This condition is illustrated in Fig. I. The MC and MR curves are the
usual marginal cost and marginal revenue curves, respectively. MC
and MR curves intersect at two points, PI and P2. Thus, the first order
condition is satisfied at both the points but mathematically, the
second order condition requires that its second derivative of the
profit function is negative. When second derivative of profit function
is negative, it shows that the total profit curve has bent downward
after reaching the highest point on the profit scale. The second
derivative of the total profit function is given as:
a2TR
=
a2TP
=
a2TR-
a2TC<0 aQ2 aQ2 aQ2 aQ2
(4)
But it requires:
a2TR-
a2TC< 0aQ2 aQ2
a2TR<
a2TC
< 0aQ2 aQ2
Since & TR/aQ2 is the slope of MR and & a2 TC/aQ2 is the slope
of MC, the second-order condition can also be written as:
Slope of MR < Slope of MC. It implies that MC curve must
intersect the MR curve. To conclude, profit is maximised where both
the first and second order conditions are satisfied.
Example
It is known that:
TR = P.Q
where,
(5)
P = Price of a single quantity and
Q = Total quantity.
Suppose price (P) function is given as
P = 100 – 2Q
(6)
Then TR = (100 – 2Q) Q
Or, TR = 100Q – 2Q2
(7)
And also suppose that the total cost function as given as
TC = 10 + 0.5Q2
(8)
Applying the first order condition of profit maximisation and
finding the profit maximising output. It is known that profit is
maximum where:
MR – MC
or,
aTR
=
aTC
aQ aQ
(9)
Putting the values of Equation (7) and (8) in (9)
MR =aTR
<aTC
= 100 – 4QaQ aQ
and
MC =aTC
=QaQ
Thus, profit is maximum where
MR = MC
100 – 4Q = Q
5Q = 100
Q = 20
The output 20 satisfies the second order condition also. The
second order condition requires that:
a2TR<
a2TC<0
aQ2 aQ2
In order words, the second-order condition requires that
aMR-
aMC<0
Q Q
Or
a(100 – 40)
-
a(Q)
<0aQ aQ
- 4 – 1 <0
Thus, the second-order condition is also satisfied at output 20.
CONTROVERSY OVER PROFIT MAXIMISATION OBJECTIVE:
THEORY vs. PRACTICE
According to the traditional theory, profit maximisation is the sole
objective of a business firm. In practice, however, firms have been
found to be pursuing objectivies other than profit maximisation. For
the large business firms, pursuing goals other thon profit
maximisation is the distinction between the ownership and
management. The separntion of manllgement from the ownership
gives managers an opportunity to set goals for the firms other than
protit maximisation. Large firms pursue goals such as sales
maximisalioll, mllximisulioll of lilllllagcrial utility function,
maximisation of firm's growth rate, making a target profit, retaining
market share, building up the net worth of the firm, etc. Secondly,
traditionnl theory assumes perfect knowledge about current murket
conditions and the future developments in the business
environment of the firm. Thus a business firm is fully aware of its
demand and cost functions in both short and long runs. The market
conditions (Ire assumed to be certain. On the contrary, it is also
recognised that the firms do not possess the perfect knowledge of
their costs, revenue, and their environment. They operate in the
world of uncertainty. Most of the price and output decisions are
based on probabilities.
Finally, the marginality principle in which MC and MR are same
has been found to be absent in the decision-making process of the
business firms. Hall and Hitch have found, in their study of pricing
practices in UK, that the firms do not pursue the objective of profit
maximisation and that they do not use the marginal principle of
equalising MR and MC in their price and output decisions. Most firms
aim at long-run profit maximisation. In the short-run, they set the
price of their product on the basis of average cost principle to cover
average cost and its components, average variable cost and
average fixed cost.
It also takes into account normal profit usually 10 per cent.
Gordon, a famous economist, has concluded that the real business
world is much more complex than the one which is based on
hypothesis and assumptions. The extreme complexity of the real
business world and ever-changing conditions makes it difficult for a
business firm to use its past experience in order to forecast
demand, price and costs. The average-cost principle of Rricing is
widely used by the firms and the marginal costs and marginal
revenu~ are ignored. On the basis of many such studies, it can be
said that the pricing practices are related to pricing theories.
THE FAVOUR OF PROFIT MAXIMISATION
The arguments against the profit-maximisation assumption,
however, should not mean that pricing theory is not related to the
actual pricing policy of the business firms. Many economists has
strongly supported the profit maximisation objective and the
marginal principle of pricing and output decisions. The empirical
and theoretical policies support the marginal rule of pricing in the
following way:
In two empirical studies of 110 business firms, J.S.Earley has
concluded that the firms do apply the marginal rules in their pricing
and output decisions. Fritz Maclup has argued that empirical studies
by Hall and Hitch, and Lester do not provide conclusive evidence
against the marginal rule and these studies have their own
weaknesses. He further argued that there has been a
misundestanding regarding the purpose of traditional theory. The
traditional theory explains market mechanism, resource allocation
through price mechanism and has a predictive valu. The
significance of marginal rules in actual pricing system of firms could
not be considcred becausc of lack of communication between the
busincssmcn and the researchers as they use different terminology
like MR, Me and clasticitics. Also, Maclup is of the opinion that the
practices of setting price equal to the average variable cost plus a
profit margin, is not inequitable with the marginal rule of pricing.
ARGUMENTS IN FAVOUR OF PROFIT MAXIMISATION
HYPOTHESIS
The traditional theory supports the profit maximisation hypothesis
also on the following grounds:
Profit is essential for survival of a business: The
survival of all the profitoriented firms in the long run depends
on their ability to make a reasonable profit depending on the
business conditions and the level of competitior. Profit is the
biggest incentive for work. It is the driving force behind the
business enterprise. It encourages a man to work to do the
best of his ability and capacity. Making a profit is a necessary
condition for the survival of the firm. Once the firms are able
to make profit, they try to maximise it.
Achieving other objectives depends on the ability of a
business to make profit: Many other objectives of
business are maximisation of managerial utility function,
maximisation of long-run growth, maximisation of sales
revenue. The achievement of such alternative objectives
depends wholly or partly on the primary objective of making
profit.
Profit maximisation objective has a greater predicting
power: As comparcd to other business objectives, profit
maximistion assumption has been found 10 be good in
predicting ccrtain aspects relatcd to a business. Friedman
supports this by saying that the profit maxilllisation is
considered to be good only if it predicts the business
behaviour and the business trends correctly.
Profit is a more reliable measure of efficiency of a
business: Thought not perfect, profit is the most efficient
and reliable measure of the efficiency of a firm. It is also the
source of internal finance. The recent trend shows a growing
dependence on the internal finance in the indlstrially
advanced countries. In fact, in developed countries, internal
sources of finance contribute more than three-fourths or lotal
linance. Keeping this in mind, it can be said that profit
maximisation is a more valid business objective.
Alternative objectives of Business Firms
The traditional theory does not distinguish between owners and
managers' interests. The recent theories of firm, which arc also
called managerial and behavioural theories of firm, assume owners
and managers to be separate entities in large corporations with
different goals and motivation. Berle and Means were the two
economists, who pointed out the distinction between the ownership
and the management, which is also known as Berle-Means-Galbraith
(BMG) hypothesis. The B-M-G hypothesis states the following:
The owners controlled business firms have higher profit rates
than manager controlled business firms, and
The managers have no in::entive for profit maximisation. The
managers of large corporations, instead of maximising profits,
set goals for themselves that helps in controlling the owners
also. In this section, some important alternative objectives of
business firms, especially of large business corporations are
also discussed.
Baumol's Hypothesis of Sales Revenue Maximisation
According to Baumol, "maximisation of sales revenue is an
alternative to profitmaximisation objective". The reason behind this
objective is to clearly distinct ownership and management in large
business firms. This distinction helps the managers to set their goals
other than profit maximisation goal. Under this situation, managers
maxi mise their own utility function. According to Baumol, the most
reasonable factor in managers' utility functions is maximisation of
the sales revenue.
The factors, which help in explaining these goals by the
managers, are following:
Salary and other earnings of managers are more closely
related
to seals revenue than to profits.
Banks and financial corporations look at sales revenue while
financing the corporation.
Trend in sale revenue is a good indicator of the performance
of
the business firm. It also helps in handling the personnel
problems.
Increasing sales revenue helps in enhancing the prestige of
managers while profits go to the owners.
Managers find profit maximisation a difficult objective to fulfil
consistently over tillle and at the same level. Profits may
fluctuate with changing conditions.
Growing sales strengthen competitive spirit of the business
firm in the nlilrkd and vice versa.
So far as cmpirical validity of sales revenue maximisation
objective is concerned, realistic evidences are unsatisfying. Most
empirical studies are, in fact, based on inadequate data because the
necessary data is mostly not available. If total cost lilllction
intersects the total revenue function (TR) function before it reaches
its highest point, Baumol's theory fails. It is also argued that, in the
long run, sales maximisation and profit maximisation objective can
be merged into one. In the long rnll, sales maximisation lends to
yield only normal levels of profit, which turns out to be the
maximum under competitive conditions. Thus, profit maximisation is
not inequitab!c with sales maximisation objective.
MARRIS's HYPOTHESIS OF MAXIMISATION OF FIRM'S
GHOWTH RATE
According to Robin Marris, managers maximise firm's growth rate
subject to managerial and financial constraints. Marris defines firms'
balanced growth rate (G) as follows:
G = Gd = Gc
where,
Jd = growth rate of dcmand for firms product.
Gc = growth rate of capital supply to the firm.
In simple words, a firm's growth rate is considered to be
balanced when demand for its product and supply of capital to the
firm increase at the same rate. The two growth rates according to
Marris, are translated into two utility functions such as:
Manager’s ut i I ity function
Owner’s utility function
The manager’s utility function (Um) and owner's utility function
(Uo) may be specified as follows:
Um = f (salary, powcr, job security, prestige, status) and
Un = f (output, capital, market-share, profit, public esteem).
Owner's utility function (Vo) implies growth of demand for
firms' products and supply of capital. Therefore, maximisation of Uo
mcans maximisation of demand for a firm's products or growth of
supply of capital.
According to Marris, by maximising these variables, managers
maximise both their utility function and that of the owner's. The,
managers can do so because most of the variables such as salarics,
status, job security, power, etc., appearing in their own utility
function and those appearing in the utility function of the owners
such as profit, capital market, share, etc. are positively and strongly
correlated with the size of the firm. These variables depend on the
maximisation of the growth rate of the firms. The managers,
therefore, seek to maximise a steady growth rate. Marris's theory,
though more accurate and sophisticated than Baumol's sales
revenue maximisation, has its own weaknesses. It fails to deal
satisfactorily with the market condition of oligopolistic
interdependence. Another serious shortcoming is that it ignores
price determination, which is the main concern of profit
maximisatioll hypothesis. In tbe opinion of many economists,
Marris's model too, does not seriously challenge the profit
maximisation hypothesis.
Williamson's Hypothesis of Maximisation of Managerial
Utility Function
Like Baulmol and Marris, Willamson argues that managers are very
careful in pursuing the objectives other than profit maximisation.
The managers seek to maxi mise their own utility function subject
to a minimum level of profit. Managers' utility function (U) is
expressed below: V = f(S, M, ID)
where,
S = additional expenditure on staff
M = Managerial emoluments
ID = Discretionary investments
According to Williamson's hypothesis, managers maximise
their utility function subject to a satisfactory profit. A minimum
profit is necessary to satisfy the shareholders and also to secure the
job of managers. The utility fU'1ctions which managers seek to
maximise, include both quantifiable variables like salary and slack
earnings anti non-quantitative variable such as prestige power,
status, job security, professional excellence, etc. The non-
quantifiable variables are expressed in order to make them work
effectively in terms of ex; ense preference defined as satisfaction
derived out of certain types of expenditures. Like other alternative
hypotheses, Williamson's theory too suffers from certain
weaknesses. His model fails to deal with the problem of oligopolistic
interdependcncc, Willinmsoli's theory is said to hold only where
rivalry between firms is not strong. In case there is slrong rivalry,
profit maximisation is claimed to be a more appropriate hypothesis.
Thus, Williamson’s managerial utility function too does not offer a
more satisfactory hypothesis than profit maximisation.
Cyert-March Hypothesis of Satisfying Behaviour
Cyert-March hypothesis is an extension of Simon's hypothesis of
firms' satisfying behaviour. Simon had argued that the real business
world is full of uncertainly liS accurate and adequate data are not
readily available, If data are available, managers have little time
and ability to process them, Managers alsc work under a number of
constraints. Under such conditions it is not possible for the firms to
act in terms of consistency assumed under profit maximisation
hypothesis. Nor do the firms seek to maximise sales and growth.
Instead they seek to achieve a satisfactory profit or a satisfactory
growth and so on. This behaviour of business firms is termed as
satisfaction behaviour.
Cyert and March added that, apart from dealing with uncertainty,
managers need to satisfy a variety of groups of people such as
managerial staff, labour, shareholders, customers, financiers, input
suppliers, accountants, lawyers, etc. All these groups have
confiicting interests in the business firms. The manager's
responsibility is to satisfy all of them. According to the Cyert-March,
"firm's behaviour is satisfying behaviour, which implies satisfying
various interest groups by sacrificing firm's interest or objectives."
The basic assumption of satisfying behaviour is that a firm is an
association of different groups related to various activities of the
firms such as shareholders, managers, workers, input supplier,
customers, bankers, tax authorities, and so on. All these groups
have some expectations from the firm, which are needed to be
satisfied by the business firms. In order to clear up the conflicting
interests and goals, managers fonn an objective level of the firm by
taking into consideration goals such as production, sales and
market, inventory and profit.
These goals and objective level are set on the basis of the
managers past experience and their assessment of the future
market conditions. The objective level is also modified and revised
on the basis of achievements and changing business environment.
But the behaviouraI theory has been criticised on the following
grounds:
Though the behavioural theory deals with the activities of the
business firms, it does not explain the firm's behaviour under
dynamic conditions in the long run.
It cannot be used to predict the firm's activities in the future.
This theory does not deal with the equilibrium of the business
industry.
This theory fails to deal with interdependecne or the linns and
its impact on linn's behaviour.
ROTHSCHILD's HYPOTHESIS OF LONG-RUN SURVIVAL AND
MARKET SHARE GOALS
Rothschild suggested another alternative objective and alternative
to profit maximisation to a business firm. Accordingto Rothschild,
the primary goal of the firm is long-run survival. Some other
economists have suggested that attainment and 'retention of a
market share constantly, is an additional objective of the business
firms. The managers, therefore, seek to secure their market share
and long-run survival. The firms may seek to maxi mise their profit
in the long run though it is not certain.
Entry-prevention and Risk-avoidancel
Another alternative objective of firms as suggested by some
economists is to prevent the entry of new business firms into the
industry. The motive behind entry prevention may be any of the
following:
Profit maximisation in the long run.
Securing a constant market share.
Avoidance of risk caused by the unpredictable behaviour of
new firms.
The evidence related to the firms to maximise their profits in the
long run, is not certain. Some economists argue that if management
is kept separate from the ownership, the possibility of profit
maximisation is reduced. This means that only those firms with the
objective of profit maximisation can survive in the long run. A
business firm can achieve all other subsidiary goals easily by
maximising its profits. The motive of business firms behind entry-
prevention is also to secure a constant share in the market.
Securing constant market share also favours the main objective of
business firms of profit maximisation.
A Reasonable Profit Target
A business firm has variolls objectives to achieve. The survival of a
firmdepends on the profit it can make. So, whatever the goal of the
firm may be, it has to be a profitable firm. The other goals of a
business firm can be sales revenue maximisation, maximisation of
firm's growth, maximisation of managers’ utility function, long-run
survival, market share or entry-prevention. In technical sensc,
maximisation of profit, as a business objective, may not sound
practical , but profit has to be there in the objective function of the
firms for its survival. The firms may differ on the level of profit and
the extent to which it is to be achieved by various firms. Some firms
set standard profit as their objective, while some of them may set
target profit and some reasonable profit as their objective to be
achieved. A reasonable profit, as a business objective, is the most
common objective. The policy question related to setting standard
or criteria for reasonable profits are as follows:
Why do modem corporations aim at a reasonable profit rather
than attempting to maximise profit?
What are the criteria for a reasonable profit?
How should reasonable profits be determined?
Following are the suggestions as given by various economists
to answer the above policy questions:
1. Preventing entry of competitors: Under imperfect
market conditions, profit maximisation generally leads
to a high pure profit, which attracts competitors,
especially ill case of a weak monopoly. Therefore, the
firms adopt a pricing and a profit policy that assures
them a reasonable profit. At the same time, it also
keeps the potential competitors away.
2. Maintaining a good public image: It is often
necessary for large corporations to project and maintain
a good public image. This is because if public opinion
turns against it and government officials 'start
questioning the profit figures, firms may find it difficult
to work smoothly. So most firms set their prices lower
than that to earn the maximum profit but higher enough
to ensure a reasonable profit.
3. Restraining trade union demands: High profits
make trade unions feel that they have a share in the
high profit and therefore they demand for wage-hike.
Wage-hike may interrupt the firm’s objective of
maximising profit. Any delay in profit is sometimes used
as a weapon against trade union activities.
4. Maintaining customer goodwill: Customer's goodwill
plays a significant role in maintaining and promoting
demand for the product of a firm. Customer's goodwill
depends on Jhe quality of the product and its fair price
to a large extent. Firms aiming at bcllcr profit prospects
in the long run, give up their short-run profit
maximisation objective in favour of a reasonable profit.
5. Other factors: The other factors that interrupts the
profit maximisation objective include the following:
A. Managerial utility function, which is preferable for,
profits maximisation to firms.
B. Friendly relations between executive levels within
the firm.
C. Maintaining internal control over management by
restricting firm's size and profit.
Standards of Reasonable Profits
Standards of reasonable profits are determined when a firm
chooses to make only reasonable profits rather than to maximise its
profit. The questions that arise in this regard are as follows:
What form of profit standards should be used?
How should reasonable profits be determined?
These questions can be understood after going through the
following explanatory points.
FORMS OF PROFIT STANDARDS
Profit standards is determined in terms of the following:
Aggregate money terms
Percentage of sales, and
Percentage return on investment.
All these standards are determined for each product separately.
Among all the fonns of profit standards, the total net profit of the
firm is more common than other standards. But when the purpose is
to discourage the competitors, then the target rate of return on
investment is the appropriate profit standard, provided the cost
curves of competitors' are similar. The profit standard in terms of
ratio to sales is not an appropriate standard because this ratio
varies widely from linn to firm, evens irthey nil hove the snme
return on capital invested. These differences are following:
Vertieal integration of production process
Intensity of mechanisation
Capital structure
Turnover
SETTING THE PROFIT STANDARD
The following arc the important criteria that are considered while
selling the standards for a reasonable profit.
Capital-attracting standard: An important criterion of profit
standard is that it must be high enough to attract external
capital such as debt and equity. For example, if the firm's
stocks are sold in the market at 5 times their current earnings,
it is necessary for a firm to earn a profit of 20 per cent of the
total investment But there are certain problems associated
with this criterion, which are as follows:
Capital structure of the firms such as the proportions of
bonds, equity and preference shares, which affects the
cost of capital and thereby the rate of profit.
If the profit standard is based on current or long run
average cost of capital or not. The problem in this case
arises as it may also vary widely from company to
company.
Plough-back' standard: This standard is appropriate in case
company depends on its own sources for financing its growth.
This standard involves the aggregate profit that provides for an
adequate plough-back for financing a desired growth of the
company without resorting to the capital market. This standard
of profit is used when liquidity is to be maintained by a firm
and a debt is to be avoided as per the profit policy of the firm.
This standard is socially less acceptable than capital attracting
standard. From society's point of view, it is more desirable that
all carnings are distributed to stockholders and they should
decide the further investment pattern. This is based on a belicf
that an individual is the best judge of his resource use and the
market forces allocate funds more efficiently, On the other
hand, retained eamings, which are under the control or the
managemcnt are likely to be wasted on low-earning projects
within a business firm. But to choose the most suitable policy
among marketing and management the abilities of the
management and outside investors are to be considered. This
helps in estimating the earnings prospects of a firm.
Normal earnings standard: Another important criterion for
setting standard of reasonable profit is the normal earnings of
firms of an industry over a period. This serves as a valid
criterion of reasonable profit, provided it should take into
consider the following points:
o Attracting external capital
o Discouraging growth of competition
o Keeping stockholders satisfied.
When average of normal earnings of a group of firms is used,
then only comparable firms are chosen. However, none of these
standards of profits is perfect. A standard should, therefore be
chosen after giving due consideration to the existing marke
conditions and public attitudes. Different standards arc used for
different purposes because no single criterion satisfies all conditions
of the customers.
PROFIT AS CONTROL MEASURE
An important aspect of profit is its use in measuring and controlling
perfonnances of the individuals of the large business firms.
Researches have concluded that the business individuab of middle
and high ranks often deviate from profit objective and try 10
maximise their own utility functions. They give importance to job
security, personal ambitions for promotion, larger perks, etc. But
this often conflicts with firms' profit-making objective. The reasons
for conflicts as given by Keith Powlson are as follows:
More energy is spent in expanding sales volume and product
lines than in raising profitability.
Subordinates spend too much time and money doing jobs
perfectly regardless of its cost and usefulness.
Individuals depend more to the needs of job security in the
absence of any reward.
In order to control the conllicts and directing the individuals
towards the profit objective, the top management uses
decentralisation and control-by-profit techniques. Decentralisation
is achieved by changing over from functional division of business
activities such as production branch, sales division, purchase
department, etc. to a system of commodity wise division. By doing
so, managerial responsibilities are fixed in terms of profit. Under the
general policy framework, managers enjoy self-sufficiency in their
operations. They are allotted a certain amount to spend and a profit
target to be achieved by the particular division. Profit is then-the
measure of performance of each individual, not of the sales or
quality. This kind of reorganisation of management helps in
assessing profit-performance of every individual. The two important
problems that arise in the determination of profits are as follows:
Either the profit goals are set in terms of total net profit for
the divisions or they should be restricted to their share in the
total net profit.
Determination of divisional profits when there is a vertical
integration. The most appropriate profit standard of divisional
performance is calculated by deducting current expenses
from revenue of the firm.
Profit is essential for survival of a business. In the absence of
profits, the organisations will use up their own capital and close
down. It also helps in replacing obsolete machinery and equipment
and thus ensures the continuity of a business.
Conclusion
Profit maximisation is the most popular hypothesis in economic
analysis, but there are many other important objectives, which are
not to be avoided by any firm. Modem business firms pursue
multiple objectives. The economists consider a number of
alternative objectives of business firms. The main factor behind the
multiplicity of the objectives, especially in case of large business
firms, is the separation of management from the- ownership.
Moreover, profit maximisatjon hypothesis is based on time. The
empirical evidence against this hypothesis is not conclU3ive and
unambiguous. The alternative hypotheses are also not so strong to
repiace the profit maximisation hypothesis. In addition to it, profit
maximisation hypothesis has a greater explanatory and predictive
power than any of the alternative hypotheses. Therefore, profil
maximisation hypothesis still fornls the basis of firms' behaviour.
PROFIT PLANNING AND FORECASTING
A business is considered to be sound if it includes consistency in
earning profit while considering the various risks as well. A firm is
faced with a number of untertainties. 1bese uncertainties are in -
terms of nature of consumer needs, the diverse nature of
competition, the uncontrollable nature of most elements of cost and
the continuous technological developments. The uncertainty about
the pattern and extent of consumer demand for a particular product
increases the degree of risk faced by the firm. The nature of
competition is related to either product, price or to both
simultaneously. Prodoct competition is more important till 'the
product reaches the stage of maturity. Price competition begins a
fier the product is established and reaches the maurity stage.
During the growth stage, the risk of obsolescence of a product and
shortening of the product life cycle is more. The degree of risk
involved in product competition is greater than in price competition.
When the prices rise continuously, no firm can be certain of its
internal cost structure. This is because it does not have any control
over the prices of raw materials or the wages to be paid to the
individuals. In course of time, continuous technological
improvements may make production completely obsolete. If an
improved process is available, a firm can restrict its risk by
neglecting its fixed investment. If it does not have an access to the
improved processes, it may have to go out of business. Unless a
firm is prepared to face the uncertainties, as a result of risk
element, its profits will be changed. To plan for profits, a thorough
understanding of the relationship of cost, price and volume is
ext~emely helpful to business individuals. The most important
method of determining the cost-volumeprofit relationship is break-
even analysis, also known as cost-volume-profit (C-V-P) analysis.
Break-even analysis involves the study of revenues and costs of a
firm in relation to its volume of sales. It also includes the
determination of that volume at which the firm's costs and
revenues will be equal. The break-even point (BEP) may be defined
as that level of sales at which total revenue is equal to the total
costs and the net income is zero. This is known as no-profit no-loss
point. The main objective of the break-even analysis is not simply to
find out the BEP, but to develop an understanding between the
relationships of cost, price and volume.
DETERMINATION OF THE BREAK-EVEN POINT
It may be determined either in terms of physical units or in money terms. This
method is convenient for a firm producing single prdducts only. The break-even
volume is the number of units of the product, which must be sold to earn revenue.
This revenue should be enough to cover all expenses, both fixed and variable. The
selling price of all units covers not only its variable cost but also leaves a margin
called contribution )l1argin to contribute towards the fixed costs. The break-even
point is reached when sufficient number of units has been sold so that the total
contribution margin of the units sold is equal to the fixed costs. The formula for
calculating the break-even point is:
Fixed costs
BEP = contribution margin per unit
Where the contribution margin is: selling price Variable costs per
unit.
Example 1: Suppose the fixed costs of a Factory are Rs. 10,000 per yenr, the variable
costs are Rs. 2.00 per unit and the selling price is Rs. 4.00 per unit. The break~even
point would be:
BEP =Rs. 10,000
= 5,000 units(4-2)
In other words, the company would not make any loss or profit
at a sales volume of 5,000 units as shown below:
Sales RS.20,000 Cost of goods sold: Variable cost @ Rs.2.00
Rs 10,000
Fixed costs Rs. 10,000 Rs.20,OOO Net Profit Nil
Solution. Multi-product firms are not in a position to measure
the break-even point in terms of any common unit of product. It is
convenient for them to determine their break-even point in terms of
total rupee sales. The break-even point is the point where the
contribution margin is equal to the fixed costs. The contribution
margin is expressed as a ratio to sales. For example, if the sales is
Rs. 200 and the variable costs of these sales is Rs. 140, the
contribution margin, ratio is (200 - 140)/200 or 0.3.
The formula for calculating the break-even point is:
BEP =Fixed costs
contribution margin ratio
Example 2:
Sales Rs. 10,000 Variable costs Rs. 6,000Fixed costs RS. 3,000
With the help of given information, calculate net profit.
Solution. The contribution margin ratio is (10,000-6,000)/10,000 =
0.4
BEP =Fixed costs
contribution margin ratio
3,000= Rs. 7 500
0.4
Sales value Rs.7,500 Less: Variable costs Rs.4,500 (0.6 x 7,500) Fixed costs Rs.3,000 Net profit Nil
Example 3: Sales were Rs. 15,000 producing a profit of Rs. 400
in a week. In the next week, sales amount to Rs. 19,000 producing a
profit of Rs. 1,200. Find out the BEP.
Solution.
Increase in sales 19,000 - 15,000 = Rs. 4,000
Increase in profit 1,200 - 400 = Rs. 800
Increase in variable costs 4,000 - 800 = Rs. 3,200
Over sales of Rs. 4,000, variable costs are Rs. 3,200.
Hence VC per rupee of sale is 3,200 + 4,000 = 0.80.
Fixed costs will be as under:
Variable cost 15,000 x 0.80 12,000Profit 400VC + Profit 12,400
Sales value 15,000Fixed cost 2,600
=
S – V=
15,000 – 12,000
=
3,000= 0.2S 15,000 15,000
=2,600
= Rs. 13,0000.2
Break-even Point as a Percentage of Full Capacity
Full capacity can be defined as the maximum possible volume
attainable with the firm's existing fixed equipment, operating
policies and practices. Break-even point is usually expressed as a
percentage of full capacity. Considering the example I, the full
capacity of the firm is 10,000 units; the break-even point at 5,000
units can be expressed as 50 per cent of full capacity.
Multi-product Manufacturer and Break-even Analysis
Most manufacturers produce more than one type of product. The
determination of BEP in such cases is a little complicated and is
illustrated below:
Example 4: A manufacturer makes and sells tables, lamps and
chairs. The cost accounting department and the sales department
have supplied the following data:
~Selling Price
VC
Per unit
% of rupee
Sales volume
Product
Rs. Rs.
Tables 40 30 20
Lamps 50 40 30
Chairs 70 50 50
Capacity of the firm is Rs. 1,50,000 of total sales value.
Annual fixed cost - Rs. 20,000
Calculate (1) BEP and (2) Profit if firm works at 50 per cent of
capacity.
Now, BEP =
FC
Contribution margin ratio
Solution. The contribution towards fixed cost in each case
is: .Table Rs. 10
Lamps Rs. 10
Chairs Rs. 20
Now, these contributions are to be converted into percentages
of selling prices, the formula to be applied is:
Contribution percentage =Selling price - VC
x 100Selling price
Thus, the contribution percentage for individual items is:
40 - 30 1
Table ---x 100 = - xl 00 = 25 per cent
40 4
50 - 40 1
---x 100 = - xl 00 = 20 per cent
50 5
70 - 50 2
---x 100 = -x 100 = 28.57 per cent
70 7
Now, we multiply the contribution percentage of each of the
products by the percentage of sales volume for that particular
product and add the figures obtained. This gives the total
contribution per rupee of sales volume for tables, lamps and
chairs. This is done as follows:
Contribution % of Sales
Tables 25.00 % X 20 % = 5.00 %
Lamps 20.00 % X 30 % = 6.00 %
Chairs 28.57 % X 50%= 14.28%·
25.28 % say 25 %
--
This 25 per cent is the total contribution per rupee of overall
sales given the present product sales mix. The calculations
required in the question are as follows:
1. BEP: The BEP orthe firm is calculated as under:
BEP =Fixed costs
=20,000
Rs. 80,000Contribution marginper unit 25%
2. Profit: Calculation of profit or loss at various volumes can
also be made easily. If the firm produces at 80 per cent of
capacity, the profit will be calculated as under:
Profit = Total revenue - Total costs
= 80% of (1,50,000) - Fixed costs - Variable costs
= 1,20,000 - 20,000 - 75% of (1,20,000)
= 1,20,000 - 20,000 - 90,000
= Rs. 10,000
Break-even Charts
Break-even analysis is very commonly presented by means of
break even charts. Break-even charts are also known as profit-
graphs. A break-even chart prepared on the basis of example 1
above is given in Figure 5.2. In this figure, units of product are
shown on the horizontal axis OX while revenues and costs are
shown on the vertical axis OY. The fixed costs of Rs. 10,000 are
shown by a straight line parallel to the horizontal axis. Variable
costs are then plotted over and above the fixed costs. The resultant
line is the total cost line, combining both variable and fixed costs.
There is no variable cost line in the graph. The vertical distance
between the fixed cost and th~ total cost lines represents variable
costs. The total cost at any point is the SU!TI of Rs. 10,000 plus Rs.
2.00 per unit of variable cost multiplied by the number of units sold
at that point. Total revenue at any point is the unit price of Rs. 4.00
multiplied by the number of units sold. The break-even point
corresponds to the point of intersection of the total revenue and the
total cost lines. A perpendicular from the BEP to the horizontal axis
shows the break-even point in units of the product. Dropping a
perpendicular from BEP to the vertical axis shows the break-even
sales value in rupees. The firm would suffer a loss at any point
below the BEP. Total costs are more than total revenue. Above the
BEP, total revenue exceeds total costs and the firm makes profits.
Since profit or loss occurs between costs and revenue lines, the
space between them is known as the profit zone, which is to the
right of the BEP, and the loss zone, which is to the len of the BEP.
The following Figure 5.2 shows Break-even Chart.
The break-even chart remains where the BEP is measured in
terms of sales value rather than in physical units. The only
difference is that the volume on the X-axis is measured in terms of
sales value. In that case, a perpendicular frqm the point BEP to
either axis would show the break-even rupee sales value. The same
type of chart could be used to depict the BEP in relation to full
capacity. In this case the horizontal axis would represent the
percentage of full capacity, instead of physical units or the sale
value.
Break-even Chart-A Variation
The break-even chart is a variation of the traditional break-even
graph. This graph is prepared with the variable cost line instead of
fixed cost line, starting at the zero axis. On it is superimposed the
total cost, the line which includes the fixed cost and is, therefore,
parallel to the variable cost line. This graph is as much useful as the
contribution to fixed cost and profit. It is more deafly shown below in
the Figure 5.3.
Profit-Volume Analysis
It is very similar to the break-even analysis and is based on the
relationship of profits to sales volume. The profit-volume graph
shows the relationship ofa firm's profit to its volume. Total profit or
loss is measured on the vertical axis above the X-axis and the loss
below it. The volume is measured on the X-axis, which is drawn at
the point of 'Zero-Profit'. Volume is usually expressed in tenns of
percentage of full capacity. The maximum loss, which occurs at zero
sales volume, is equal to the fixed cost and is shown on the vertical
axis below the X-axis. The maximum profit is earned when the firm
works at full capacity. The point of maximum profit is shown on the
vertical axis above the X-axis. The two points of maximum loss and
the maximum profit are joined by a line, which is known as the profit
line, also called PN line. The profit line can also be established by
detennining the profit at any two points within the given range of
volume and drawing a straight line through these points. The point,
at which the profit line intersects the X-axis, is the break-even point.
The space between the X-axis and the profit line shows the profit
zone, which is to the right of BEP, and the loss zone, which is to the
left of BEP. The usefulness of the graph lise in the fact that it shows
the profit or loss earned by the firm by working at different levels of
its full capacity. The following Figure 5.4 shows the profit volume
analysis.
Assumptions
1. All costs are either variable or fixed over the entire range of
the volume of production. But in practice, this assumption may
not hold well over the entire range of production.
2. All revenue is variable in nature. This assumption may Lot be
valid in all cases such as the case where lower prices are
charged to large customers.
3. The volume of sales and the volume of production are equal.
The total products, produced by the firm, are sold and here is
no change in the closing inventory. In practice, sales and
production volumes may differ significantly. However, these
assumptions are not so unrealistic so as to weaken the validity
of the break-even analysis.
4. In the case of multi-product firms, the product-mix shoulu be
stable. Fora multi-product firm, the BEP is determined by
dividing total fixed costs by an average ratio of variable profit,
also called contribution to'sales. If each product has the same
contribution ratio, the BEP is not affected by changes in the
product-mix.
However, if different products have different contribution
ratios, shift in the product-mix may cause a shift in the break-even
point. In real life, the assumption of stable product-mix is somewhat
unrealistic.
Managerial Uses of Break-even Analysis
To the management, the utility of break-even analysis lies in the
fact that it presents a picture of the profit struture of a business
firm. Break-even analysis not only highlights the areas of economic
strength and weaknesses in the firm but also sharpens the focus on
certaIn leverages which cun be opernted upon to enhance its
profitability. Through brenk-even analysis, it is possible for the
management to examine the profit structure of a business firm to
the possible changes in business conditions. For example, sales
prospects, changes in Cust structure, etc. Through break-even
analysis, it is possible to use managerial actions to maintain and
enhance profitability of the firm. The break-even analysis can be
used for the following purposes:
Safety margin
Volume needed to attaintarget profit
Change in price Change in price
Expansion of capacity
Effect of alternative prices
Drop or add decision
Make or buy decision
Choosing promotion-mix
Equipment selection
Improving profit performance
Production planning
Safety Margin
The break-even chart helps the management to know the profits
generated at the various levels of sales. But while deciding the
volume at which the firm would operate, apart from the demand,
the management should consider the safety margin associated with
the proposed volume. The safety margin refers to the extent to
which the firm can afford a decline in sales before it starts occurring
losses. The formula to determine the safety margin is:
Safety Margin
=
(Sales – BEP) x 100
Sales
Example 5: Assume that our sales in Example 1 are 8,000 units.
Safety Margin
=
(8,000-5,000) x 100= 37.5%8,000
Before incurring a loss, a business firm can afford to loose
sales up to 37.5 per cent of the present level. A decreasing safety
margin indicates that the firm's resistance capacity to avoid losses
has become poorer. A margin of safety can also be negative. A
negative safety margin is the percentage increase in sales
necessary to reach the BEP in order to avoid losses. Thus, it reveals
the minimum extent of effort in terms of sales expected by the
management. Suppose in the same example sales are us low as
4,000 units. The safety margin would be:
Safety Margin (4,000-5,000) x 100
4,000
=
= 25%
In other words, the management must strive to increase sales at
least by 25 per cent to avoid losses.
Volume Needed to Attain Target Profit
Break-even analysis is also utilised for determining the volume of
sales, necessary to achieve a target profit. The formula for target
sales volume is:
Target Sales Volume =Fixed costs + Target profit
Contribution margin per unit
.
Example 6: Continuing with the same example, if the desired
profit is Rs. 6,000, the target sales volume would be calculated as follows:
10,000 + 6,000= 8000 units2
Change in Price
The management is also faced with a problem whether to reduce
the prices or not. The management will have to consider a number
of points before taking a decision related to the change in the
prices. A reduction in price results in a reduction in the contribution
margin as well. This means that the volume of sales will have to be
increased to maintain the previous level of profit. The higher the
reduction in the contribution margin, the higher will be the increase
in sales needed to maintain the previous level of profit. However,
reduction in prices may not always lead to an equal increase in the
sales volume, which is affected by the elasticity of demand. But the
information about elasticity of demand may not be easily available.
Breakeven analysis helps the management to know the required
sales volume to maintain the previous level of profit. On the basis of
this knowledge and experience, it becomes much easier for -the
management to judge whether the required increase it sales will be
feasible or not. The formula to determine the new sales volume to maintain the same
level of profit, given a reduction in price, would be as under:
Qn =FC + P
SPn - VC
where Qn = New volume of sales
FC = Fixed cost
P = Profit
SPn = New selling price
VC = Variable cost per unit (n denotes new)
Example 6(a): Continuing with the same example 6, if we propose a
reduction of 10 per cent in price from Rs. 4.00 to Rs. 3.60, the new sales volume
needed to maintain the previous profit ofRs. 6,000 will be:
10, 000 +
6,000=
16, 000= 10,000 units
3.60 – 2.00 1.60
This shows that there is an increase of 2,000 units or 25 per cent
in sales. The management can also easily decide whether this
increase in sales volume is profitable for t~e business firm or not.
If a firm proposes the price increase, the question to be
considered is by how much the sales volume should decline before
profitable effect of the price increase gets eliminated.
Example 6(b): If the firm in example 6 considers an increase in
price by 12Y2per cent to Rs. 4.50, the new volume to maintain the
old profit would be:
Q 2 =10, 000 +
6,000=
16, 000= 6,400 units
4.50 – 2.00 2.50
In other words, if the fall in sales, due to an increase in price,
were less than 1,600 units or 20 per cent, it would be profitable for
the firm to increase the price. But if the decline were more than
1,600 units, the proposed price increase would reduce the profit.
Change in Costs
Break-even analysis' helps to analyse the changes in variable
cost and fixed cost, which are explained as follows.
Change in variable cost: An increase in variable costs leads
to a reduction in the contribution margin. In such a situation, a firm
determines the total sales volume needed to maintain the prescnt
profits withcut any increase in price. A firm also determines the
price lhut should be set to maintain the present level of profit
without any change in sales volume. The formulae to determine the
new quantity or the new selling price, given a change in variable
costs, are:
1. The new quantity will be:
Qn =FC +P
SP - VC n
2. The new selling price will be:
SPn = SP + (VCn- VC)
Example 6(c): Continuing with the example 6, if variable cost
increases from Rs. 2 to Rs. 2.50 per unit.
Q 2 =10, 000 +
6,000=
15, 000= 10,667 units
4 – 2.50 1.50
SPn = 4 + (2.50 - 2) = Rs. 4.50
Change in fixed cost: An increase in fixed costs of a firm is
caused either by external circumstances such as an increase in
property taxes or by a managerial decision such as an increase in
executive salaries. In both the cases, the affect is to raise the break-
even point of the firm, while keeping the prices unchanged. The
same determination is undertaken by the firm regarding the sales
volume while keeping the profit level same as before. The formulae
to determine the new quantity or the new price, given a change in
fixed costs, would be:
1.
Qn= Q +FCn – FC
SP - VC
2.
SPn = SP +FCn – FC
Q
Example 6 (d): Continuing with the same example 6, if fixed
cost increases from Rs. 10,000 to Rs. 15,000.
Expansion of Capacity
The management may also be interested in knowing whether to
expand production capacity or not, through the installation
equipment. Though even analysis, it wuuld be possible to examine
the various applkutions of this proposal or installation of the
additional equipment. The following example illustrates the points
involved.
Example 7: A textile mill is considering a proposal to increase
its investment in fixed assets. If it decides to do so, fixed expenses
will go up by Rs. 5,00,000 per year without affecting the percentage
of variable expenses. With the present plant, the maximum
production is estimated at an amount, which would enable the
company to make annual sales of Rs. 60,00,000. The increased
production with the additional plant would permit the company to
make annual sales of Rs. 80,00,000. The relevant cost, sales and
profit data for 1997 are:
Sales Rs. 50,00,000
Costs and expenses: Fixed Rs. 15,00,000 Variable Rs. 32,00,000 Rs. 47,00,000 Net profit Rs. 3,00,000
There are a number of points involved in the decision on
expansion of capacity. The information regarding the expansion of
capacity is as follows:
Existing Plant Expanded Plant Capacity 0% 100 % 0% 100 %
Rs. (in Lakhs) Rs. (in Lakhs)Sales - 60 - 80Fixed costs 15 15 20 20Variable costs - 38.4 - 51.2Profit (Loss) (15) 6.6 (20) 8.8
The expansion of capacity, to enable the firm so as to expand
its sales potential from Rs. 60,00,000 to Rs. 80,00,000, will
increase the maximum profit potential of the firm from Rs.
6,60,000 to Rs. 8,80,000. But there are certain risks involved.
Answer the following on the basis of above information:
1. How will the expansion of the firm's capacity will affect
the
break-even point?
2. What would be the sales volume required to maintain the
present profit with the increased fixed costs?
Solution. It is evident that the break-even point of the firm
would be pushed up from Rs. 41, 66,667 to Rs. 55, 55,556. This
means that if the sales remain at the present level, the firm would
operate at a loss.
The minimum sales volume needed to maintain the present
profit would be Rs. 63,88,889, i.e., an increase of about 28 per cent
there is another aspect. To earn the maximum profit possible at the
present sales capacity, i.e., Rs. 6,60,000 with the increase in fixed
costs, the minimum sales volume needed would be Rs. 73,88,889,
i.e., an increase of 48 per cent. So the decision on the question of
expanding capacity hinges on the possibilities of expanding sales by
the various percentages indicated above. The fact that the present
sales volume is 20 per cent less than the maximum possible sales
volume of the existing plant may be an indication that if may be
difficult to expand sales. Another way of presenting the same
infonnation is the profit-volume chart. On the assumption that
production efficiency and prices will remain unchanged, the profit-
volume chart can help in presenting the following:
The break-even points before and after expansion, and
At what capacity utilisation, the profit will be the same as at
100 percent capacity utilisation before expansion. The following
Figure 5.5. shows the profit volume chart.
In order to arrive at the data to plot on the figure, the sales,
cost and profit at either 100 per cent or nil capacity for both existing
and expanded plants should be calculated:
As can be seen from Figure 5.4, the break-even point for both
the plants lies above 70 per cent capacity utilisation. The capacity
utilisation of the expanded plant, which gives the same profit as
100 per cent capacity utilisation of the existing plant, can be easily
found. At 92 per cent of capacity utilisation, the expanded plant will
give a profit of Rs. 6,60,000.
Effect of Alternative Prices
The break-even chart can be modified to show the profit position at
difTerent price levels under assumed conditions of demand and
costs. Figure 5.5 shows the pr,ofit position at alternative prices for
the firm in example 1. As can be seen from the figure, the break-
even point becomes lower as the price increases. But it is not
necessary that the profit potential at higher prices may actually be
achieved by the firm. A price of Rs. 4 per unit with a demand at
7,000 units will give a higher profit than a price of Rs. 5 with a
demand at 4,000 units. It is not desirable for a firm to take every
price into consideration. The analyst, while choosing a trial price,
relies largely upon their experience and judgement. Customary
price is one such price. The following Figure 5.6 shows the effect of
BEP in alternative prices.
Drop or Add Decision
An economist takes the decisions regarding the following:
Addition of a new product keeping in consideration, its
cslimated revenue and cost.
Deletion of a product from the product-line keeping in
consideration, its consequent effects on revenue and cost.
Break-even analysis is also useful in taking decisions related to
product planning. It can be understood with the help of following
example:
Example 8: The following are the present cost and output data of a
manufacturer:
Product PrLe Variable costs % of(Rs.) Per unit sales
(Rs.)Book-cases 60 40 30Tables 100 60 20Beds 200 120 50
Total fixed costs per year: Rs.
75,000 Sales last year: Rs. 2,50,000.
The manufacturer is considering whether to drop the line of
taoles and replace it with cabinets. If this drop-and-add decision is
taken, the cost and output data would be as follows:
Product Price Variable costs % of sales(Rs.) Per unit
(Rs.)Book-cases 60 40 50
Tables 160 60 10Beds 200 120 40
Total fixed cost per year: Rs.
75,000 Sales this year: Rs.
2,60,000.
On the basis of ubove informntion delermine if the change worth
undertaking by the business firm?
Solution. On the basis of the information given in the question,
the profit on the present product line is computed as follows:
Rs. 60 - 40x 30% = 0.10
60
Rs. 100 - 60x 20% = 0.08
100
Rs. 200 - 120x 50% = 0.20/0.38
200
Thus, the contribution ratio is 0.38, by adding 0.10, 0.08 and
0.20.
Total contribution = Rs. 2,50,000 x 0.38 = Rs. 95,000.
Profit = Rs. 95,000 - Rs. 75,000 = Rs. 20,000.
Profit on the proposed product line would be as under:
Rs. 60 - 40x 50% = 0.17
60
Rs. 160 - 60x 10% = 0.06
160
Rs. 200 - 120x 40% = 0.16
200
Thus, the contribution ratio is 0.39.
Total contribution = Rs. 2,60,000 x 0.39 = Rs. 1,01,400.
Profit = Rs. 1, 01,400 - 75,000 - Rs. 26,400.
Hence the proposed change is worth undertaking.
Make or Buy Decision
Many business firms may opt to produce certain components or
ingredients, which are part of there finished products, or purchasing
them from outside suppliers. For instance, an automobile
manufacturer can make spark plugs or buy them. Breakeven
analysis can enable the manufacturer to decide whether to make or
buy. With the help of following example, this can be easily
understood:
Example 9: A manufacturer of sc.ooters buys certain
components at Rs. 8 each. In case he makes it himself, his fixed and
variable costs would be Rs. 10,000 and Rs. 3 per component
respectively. Should the manufacturer make or buy the component?
If the manufacturer needs more than 2,000 components per
year, to make or produce the components is more profitable than to
buy. There are some special considerations, which helps in choosing
the best option, are as follows:
Solution. This can be detennined after calculating break-even
point of the manufacturer's firm, The break-even point is as follows:
BEP =Fixed costs
Purchse price – Variable Cost
=10,000
8 - 3
=10,000
= 2,0005
Quality: By manufacturing a certain part of the product
itself, the firm is able to exercise control over quality. This
may also lead to reduction in assembly costs and increase in
consumer goodwill. This helps in enhancing the future sales.
The outside suppliers may also possess a highly specialised
knowledge, which may outshine the know-how of the firm. In
this situation a firm, a firm may feel that it cannot match with
the quality assured by outsiders. Here, a firm is advisable to
buy the high quality products from other firms so as to avoid
the loss due to poor quality. This could also result in fewer
sales.
Assurance of supply: By producing a product itself, a firm
may secure the advantage of co-ordinating the flow of parts
more effectively. Sometimes, the suppliers are unable to meet
the demand or make deliveries within the required time
period. So, this is also an advantage for the firm to produce
high quality products and to give its best for the betterment of
society.
Defence against monopoly: A firm can also manufacture
parts to protect itself against a monopoly in supply. If a firm
produces some of it products itself, the other firms are less
likely to overcharge or dictate thelT: in any respect. So
producing a part of the product is also beneficial for a firm.
Choosing Promotion-mix
Sellers often use several methods of sales promotion, such as
personal selling, advertising, etc. But the proportion of all these
methods in the promotion mix varies from seller to seller. A retail
shop may have to consider whether or not to employ a certain
number, say, five additional salesmen. Similarly, a manufacturer
may have to decide if he should spend an additional sum of Rs.
20,000 on advertising his product or not. Break-even analysis
enables him to take appropriate decisions by showing how the
additional fixed costs influence the break-even points. This can be
explained with the help of the following illustration:
Example 10: A manufacturer sells his product at Rs. 5 each.
Variable costs are Rs. 2 per unit and the fixed costs amount to Rs.
60,000. Find the following:
1. The break-even point.
2. The profit if the firm sells 30,000 units.
3. The BEP if the firm spends Rs. 3,000 on advertising.
4. The sale of manufacturer to make a profit of Rs. 30,000 after
spending Rs. 3,000 for advertisement.
Solution: Tle calculations are as follows:
BEP =FC
SP - VC
=60,000
= 20,000 units5 - 2
Profit = Total revenue - Fixed cost - Variable cost
= (5 x 30,000) - 60,000 - (2 x 30,000)
= 1,50,000 - 60,000 - 60,000
= Rs.30,000
If the firm spends Rs. 3,000 on advertising, fixed costs would rIse by Rs.
3,000, i.e., Rs. 63,000. Hence, BEP would be:
BEP =FC

Equipment Selection
Break-even analysis can also be used to compare different ways
o(doing jobs. For instance, use of simple machines, is usually best
for small quantities. But when bigger quantities are to be produced,
faster but usually costlier machines are to be employed.
Sometimes, a choice is to be made in between three or more
methods, depending upon the most economical one. The following
example explains how to determine these ranges.
Example 11: A manufacturer has to choose from amongst three
machines for his factory. The conditions, which he wants to be
fulfilled regarding the three machines, are as follows:
1. An automatic machine which will add Rs. 20,000 a year to his
fixed costs but the variable costs per unit will be only 40 p.
2. A semi-automatic machine which will add Rs. 8,000 a year to
his fixed costs but variable cost$ per unit will be Rs. 2 and
3. A hand-operated machine which will add only Rs. 2,000 a year
to his fixed costs but will cause variable costs per unit of Rs. 4.
Calculate the range of output over which automatic, semi-
automatic and hand-operated machines would be most economical.
How would you choose between hand-operated and automatic
machines, supposing the semi automatic machine does not exist?
Solution. The cost formulae for the three machines would be,
Machine Cost formula Automatic Rs. 20,000 + 0.40 S Semi-automatic Rs. 8,000 + 2.00 S Hand-operated Rs. 2,000 + 4.00 S
Now setting pairs of equations to each other, and solving
them to final the Value of S:
1. Automatic vs. Semi- Nutomatie
Rs. 20,000 + 0. 40S = Rs. 8,000 + 2S
or, 1.60S = 12,000
or, S =12000
= 7,500 units 1.60
2. Semi-automatic vs. Hand-operated:
Rs. 8,000 + 2.00S = Rs. 2,000 + 4S
or, 2S = 6,000
or, 8 = 3,000 units
Thus, up to 3,000 units, hand-operated machine is to be used.
The semiautomatic machine is to be used over the range of 3,000 -
7,500 units.
Beyond 7,500 units, automatic machine should be used. If,
however, the choice is to be made between hand-operated and
automatic machines, the former; is to be used up to 5,000 units
and, thereafter, the latter would be more economical. This is
calculated as under:
2,000 + 48 = Rs. 20,000 + 0.40
or, 3.60S = 18,000
or, 8 = 5,000 units.
IMPROVING PROFIT PERFORMANCE
There are four specific ways in which profit performance of a
business can be improved, which are as follows:
Increasing the volume of sales: Considering the example
I, the present volume of sales is 8,000 units and the
maximum production capacity 10,000 units. If the sales are
increased to the maximum production capacity, there will be
an increase in variable expenses only. The profit will increase
from, Rs.6,000 to Rs. 10,000. It will be seen that though the
increase in sales volume has been only to the extent of 25
per cent, profit has increased by 67 per cent.
Increasing the seIling price: An increase in the price
increases the contribution margin and reduces the break-
even point. Continuing with Example I, if the selling price is
increased by 10 per cent, the profit will increase from Rs.
6,000 to Rs. 9,200 showing an increase of more than 50 per
cent.
Reducing the variable expenses per unit: If the variable
expenses are reduced by 10 per cent to Rs. 1.80, the profit
will increase from Rs. 6,000 to Rs. 7,600 at the present
volume of sales. This increase is more than 25 per cent,
which is more than the percentage reduction in variable
expenses. In cost-volume-profit relationship, the higher
proportionate increase in profit than the change in selling
price or the volume of sales or the variable expenses is called
the leverage effect. At times, it is not possible to increase the
prices, but to increase the volume of sales and to reduce the
variable expenses is possible.
Reducing the fixed cost: A reduction in fixed costs, without
a change in variable expenses and the selling price, would
lead to an equal change in the profits. For example, if the
fixed expenses are reduced from Rs. 10,000 to Rs. 9,000 in
the above illustration, profit will increase from Rs. 6,000 to
Rs. 7,000. As a change in the fixed costs does not change the
contribution margin per unit, there is no leverage effect.
Production planning
Break-even analysis can also help in production is planning so as to
give maximum contribution towards profit and fixed costs. This will
be clearly understood from-the following illustration:
Example 12: The management of Swadeshi Cotton Mills,
Kanpur, is interested in finding out the quantities of cloth X and Y
for production in a week in order to maximiese profits. The total
hours required to produce 100 metres of each cloth are 20 and 25
respectively. The total hours available per week are 9,600. The
maximum possible sales of cloth X and Y for one week as estimated
are: X = 30,000 metres, Y for 40,000 metres.
The following table shows, the variable costs and selling price per metre:
- Particulars Pcr mctrc
Cloth X Cloth YVariable cost Rs.2.00 RS.3.00
Selling price RS.2.60 RS.3.80
The total expenses for one week are estimatcd at Rs. 21,400.
Find out the production plan, which the, company should follow.
How much profit shall be earned by following this production plan?
Solution. The contributions of Cloth X and Yare Re. 0.60 and Re.
0.80 per metre respectively, which are calculated by subtracting
variable cost of each from selling price. Hence, priority should be
gi~en to the production of cloth Y as it contributes more towards
meeting the fixed cost. The maximum of cloth Y that can be sold is
40,000 metres, which would require 10,000 hours. However, the
total hours available are 9,600. Hence, the maximum of cloth Y that
can be produced is 38,400 metres (9,600 x 4). The production plan
to be followed is given below:
_._-- Cloth X Nil
Cloth Y 38,400 metres
This plan shall provide profits as shown below:
Total Revenue = Rs. 38,400 x 3.80 = Rs. 1,45,920
Total cost:
Variable cost = Rs. 38,400 x 3 = Rs. 1,15,200
Fixed cost 21,400 1,36,600
Net porfit Rs. 9,320
Policy Guidelines Originating from Break-even Analysis
There are certain useful conclusions in terms of policy guidelines,
which may be drawn from break-even analysis as a result of the
effect of changing conditions on a firm's operations, policies and
actions. A high BEP indicates the weakness regarding the profit
position of the firm. To reduce the BEI therefore, the selling price
should be increased, variable and fixed costs should be reduced. If
the variable costs per unit asre large (Business 8 in Example 13), an
increase in selling price or a reduction in variable costs would be
morc eLective. Whether it is more desirable to raise prices or
practicable to cut down variable costs, depends upon competitive
market conditions, the elasticity of demand for firm's product and
the efficiency of its operations. When the cOi.lribution margin rer
unit is comparatively large (Business A in Example 13), the firm is
advised to lower the BEP by reducing the level of fixed costs.
The higher the contribution margin, the higher is the survival of
business or vice-versa. Business A with a higher contribution
margin can survive even if the prices drop to 50 paise per unit.
Business B with a lower contribution margin will have to close down
its operations if prices drop to 50 paise. In a period of boom, whcn
both the prices as well as sales rise, a firm with a higher percentage
of fixed costs to sales earns higher profits as compared to a
business with a higher percentage of variable expenses to sales. On
the other hand, in a period of depression, when both the prices as
well as sales decrease, the business with a higher percentage of
fixed costs to sales suffers greater losses than the business with a
higher percentage of variable expenses.
Example 13: The following example of two businesses, A and B,
illustrates some of the points contained in the text above.
Business A Business BSelling price per unit Re. 1.00 Re.I.OO
Variable cost per unit Re.0.20 Re.0.60
Fixed costs per year RS.5,000 Rs.2,500
With the help of above infonnation, find which of the businesses
among A and B is profitable for the business firm to suspend
operations? Give explanations to support your answer.
Solution. The break-even point of both the businesses is
6,250 units or Rs. 6,250. If the sales are 10 pefcent above the BEP,
business A gains Rs. 500 while business B gains only Rs. 250. If the
sales are below the BEP, say 5,000 units, business A loses Rs. 1,000
and business B loses only.
Rs. 500. If the market collapses and the prices also go down
to 50 paise per unit and sales drop to, say, 3,000, business A
suffers a loss of Rs. 4, 100 while business B suffers a loss of only
Rs. 2.500 (the amount of fixed expenses only ns it would find it
unprofitable to continue operntions). But one signifiennt point is
that whilc business A can continue to operate and contribute 30
paise per unit, sold towards fixed expenses. Business B will find it
profitable to suspend operations.
Limitation of Break-even Analysis
There arc some important limitations of break-even analysis,
which arc to be kept in mind while using break-even analysis.
These limitations are as follows:
When break-even analysis is based on accounting data, it
may suffer from various limitations of such data, such as
negligence towards imputed costs, arbitrary depreciation
estimates and inappropriate allocation of overhead costs.
Break-even analysis, therefore, can be sound and useful
only if the firm in question maintains a good accounting
system and uses proper managerial accounting techniques
and procedures. The figures must also be adequate and
sound. If break-even analysis is based on past data, the
same should be adjusted for changes in wages and price of
raw materials.
Break-even analysis is static in character. It is based on the
assumption of given relationship between costs and
revenues. On the one hand and input, on the other. Costs
and revenues may change over time making the projection,
based on past data wrong. Therefore, break-even analysis is
more useful only in situations relatively stable while it does
not work effectively in volatile, erratic and widely changing
ones.
Costs in a particular period may not be caused entirely by
the output in that period. For example, maintenance
expenses may be the result of past output or a preparation
for future output. It may therefore, be difficult to relate them
to a particular period.
Selling costs are especially difficult to handle in break-even
analysis. This is because changes in selling costs are a
cause and not a result of changes in output and sales.
A straight-line total revenue curve prcsumcs that any quantity
should be sold at onc price only. This implies a horizonwl
demand curve and is true only under conditions of perfect
competition. The situation of perfect ~ competition is rare in
real world, which restricts the application of many total
revenue curves.
A basic assumption in break-even analysis is that the cost-
revenue-volume relationship is linear. This is realistic only
over narrow ranges of output. For example, this type of
analysis is worthwhile in deciding if the selling price should be
50 or 60 paise, volume should be attempted at 80 per cent of
capacity rather than 85 per cent, advertising expenditure
should total Rs. 1,00,000 or Rs. 1,15,000 or the product
should be put in a package costing 70 paise rather than 90
paise.
Break-even analysis is not an effective tool for long-range use
and its use should be restricted to the short run only. The
break-even analysis should better be limited to the budget
period of the firm, which is usually the· calendar year.
The area included in the break-even analysis should be limited
if too many products, departments and plants are taken
together and graphed on a single break-even chart: it will be
difficult for the fim1 to distinguish between the good and bad
performances of the business firm.
Break-even analysis assumes that profits arc a function of
output ignoring the fact that they arc also caused by other
factors such as technological change, improved management,
changes in the scale of the fixed factors of production and so
on.
To conclude, it can be said that break-even analysis is a
device, simple, easy to understand and inexpensive and is there
fore, useful to management. Its usefulness varies from a firm to
another firm and also among industries. Industries suffering from
frequent and unpredictable changes in input prices, rapid
technological changes and constant shifts in product mix will not
benefit much from break-even analysis. Finally, break-even analysis
should be viewed as a guide to decision-making and not as a
substitute for judgement, logical thinking.
PROFIT FORECASTING
Profit planning cannot be done without proper profit forecasting.
Profit forecasting means projection of future earnings after
considering all the factors affecting the siz.e of business profits,
such as firm's pricing policies, costing policies, depreciation policy,
and so on. A thorough study including a proper estimation of both
economic as well as non-economic variables may be necessary for a
firm to project its sales volume, costs and subsequently the profits
in future.
According to joel Dean, a famous cconomist, there are three
approaches to profit forecasting, which are as follows:
Spot Projection: Spot projection includes projecting the
profit and loss statement of a business firm for a specified
future period. Projecting of profit land loss statement means
forecasting each important element separately. Forecasts are
made about sales volume, prices and costs of producing the
expected sales. The prediction of profits of a firm is subject to
wide margins of error, from forecasting revenues to the inter-
relation of the various components of the income statement.
Brcak-even analysis: It helps in identifying functional
relations of both revenues and costs to output rate, kecping in
consideration the way in which output is related to the prolits.
It also helps in doing so by relating profits fo output directly
by th.e usual data used in break-even analysis.
Environmcntal analysis: It helps in relating the company's
profits to key variabk, in the economic environment such as
the general business activity and the general price level.
These variables are not considered by a business firm.
All those factors that control profits move in regular and
related patterns such as the rate of output, prices, wages, material
costs and efficiency, which are all inter-related by their connections
with the national markets and also by their interactions in business
activity. Theories of business cycles are based on the hypothesis,
which is shown by the national values of production, employment,
wages and prices during any fluctuation in business activities. There
is no clear pattern in detailed analysis. These patterns helps in
increasing the possibility that the profits of a business firm, can be
forecast directly by finding a relation to key variables. The need is
to find a direct functional relation between profits of a business firm
and activities at national level that shows statistical signi ticance.
In practice, these three approaches need not be mutually
exclusive. Theses approaches can also be used jointly for maximum
information. In projecting the profit and lo.ss statement, the
functional relations can be used, arising out of the ratio of cost to
output and to its other determinants. In the same way, by
measuring the impact of outside economic forces upon the firms'
profit helps in facilitating good spot guesses. It can also enhance
the accuracy of break-even analysis.

LESSON NO-6
NATIONAL INCOME
National income is the final outcome of total economic activities of a
nation. Economic activities generate two kinds of flow in a modern
economy namely, product-flow and money-flow. Product-flow refers
to flow of goods and services from producers to final consumers.
Money flow refers to flow of money in exchange of goods and
services. In this exchange of goods and services, money income is
generated in the form of wages, rent, interest and profits, which is
known as factor earning. Based on these two kinds of flows, national
income is defined in terms of:
Product flow
Money flow
DEFINITION OF NATIONAL INCOME
National Income in Terms of Product Flow
National income is the sum of money value of goods and services
generated from total economic activities of a nation. Economic
activities result into production of goods and services and make net
addition to the national stock of capital. These together constitute
the national income of closed economy'. Closed economy refers to
an economy, which has no economic transactions with the rest of
the world. I lowcvcr, in an opcn ecollomy, natiollul incomc ulso
includes the net results of its transactions with the rest of the world,
i.e., exports less imports.
Economic activities should be distinguished from the non-
economic activities from national income point of view. Broadly
speaking, economic activities include all human activities, which
create goods and services that can be valued at market price.
Economic activities include production by farmers (whether for
household consumption or for market), production by firms in
industrial sector, production of goods and scrvices by thc
govcfl1ment cntcrpriscs, and services produced by business
intermediaries (wholesaler and retailcr), banks and other financial
organisations, universities, colleges and hospitals. On the other
hand, noneconomic activities arc those activities, which produce
goods and serviccs that do 110t have economic value. The non-
economic activities include spiritual, psychological, social and
political services, hobbies, service to selr serviccs of housewives
services of members of family to other mcmbers and cxchangc of
mutual services between neighbours.
National Income in Terms of Money Flow
While economic activities generate flow of goods and services, on
the other hand, they also generate money-flow in the form of
f~lctor payments such as, wages, interest, rent, prolits and earnings
of self-employed. Thus, national insome can also be obtained by
adding the factor earnings after adjusting the sum for indirect
taxes, and subsidies. The national income thus obtained is known as
national income at factor cost.
The concept of national income is linked to the society as a
whole. However, it differs fundamentally from the concept of private
income. Conceptually, national income refers to the money value of
the final goods and services resulting from all economic activities of
a country. However, this is 110t true for the private income in
addition, there are certain receipts of money or of goods and
services that are not ordinarily included in private incomes but are
included in the national incomes and vice versa. National income
includes items such as employer's contribution to the social security
and welfare funds for the benefit of employees, profits of public
enterprises and servIces of owner occupied houses. However, it
excludes the interest on war-loans, social security benefits and
pensions. Instead, these items are included in the private incomes.
The national income is therefore, not merely an aggregation of the
private incomes. However, an estimate of national income can be
obtain by summing up the private incomes after making necessary
adjustment for the items excluded from the national income.
MEASURES OF NATIONAL INCOME
The various measures of national income are as follows:
Gross National Product (GNP)
There are several measures of national income used in the analysis
of national income. GNP is the most important and widely used
measure of national income. GNP is defined as the value of final
goods and services produced during a specific period, usually one
ycar, plus the diflcrence between foreign receipts and" pnyment.
The GNP so defined is identical to the concept of 'Gross National
Income (GNl)', Thus, GNP = GNI. The difference between the two is
that while GNP is estimated on the basis of product-flows, the GNI is
estimated on the basis of money flows.
Net National Product (NNP)
Net National Product (NNP) is the total market value of all final
goods and services produced by citizens of an economy during a
given period of time minus depreciation, i.e., Gross Nationnl
Product less depreciation.
NNP = GNP - Depreciation
Depreciation is that part of total productive assets, which is
used to replace the capital worn out in the process of creating GNP.
In other words, while producing goods and services including
capital goods, a part of total stock of capital is used up. This part of
capital that is used up is termed as depreciation. An estimated
value of depreciation is deducted from the GNP to arrive at NNP.
The NNP, as defined above, gives the measure of net output
available for consumptionhy the society (including consumers,
producers and the government), NNP is the real measure of the
national income. In other words, NNP is same as the national
income at factor cost. It should be noted that NNP is measured at
market prices including direct taxes. However, indirect taxes are
not included in the actual cost of production. Therefore, to obtain
real national income, indirect taxes are deducted from the NNP.
Thus,
National income = NNP - Indirect taxes
National income: Some accounting relationships
Relations at market price GNP = GNI
o Gross Domestic Product (GDP) = GNP less net income
from abroad
o NNP = GNP less depreciation
o NDP (Net Domestic Product) == NNP less net income
from abroad
Relations at factor cost
o GNP at factor cost = GNP at market price less net
indirect taxes.
o NNP at factor cost = NNP at market price less net
indirect taxes
o NDP at factor cost = NNP at market price less net
income from ahroad
o NOP at factor cost = NDP at market price less net
indirect taxes
o NOP at factor cost = GOP at market price less
depreciation
Methods of Measuring National Income
For mcasuring the national income, the national economy is viewed
as follows:
The national economy is considered as an aggregate of
producing units combining different sectors such as
agriculture, mining, manufacturing and trade and commerce.
The whole national economy is viewed as a combination of
individuals and household owning different kinds of factors of
production, which they use themselves or sell-their factor
services to make their livelihood.
National economy is also viewed as a collection of consuming,
saving and investing units (individuals, households and
government).
The above notions of a national economy helps to measure
national Income by following three different methods:
Net output method
Factor-income method
Expenditure method
These methods are followed in measuring national income in
a ‘closed economy',
Net Output Method
This is also called as net product method or value-added method.
This method is used when whole national economy is considered as
an aggregate of producing units. In its standard form, this method
consists of three stages:
1. Measurement of gross value of domestic output in
the
various branches of production: For measuring the
gross value of domestic product, output is classified
under various categories on the basis of the nature of
activities from which they originate. The output
classification varics from country to country dey'ending
on (i) the nature of domestic activities, (ii) their
significance in aggregate economic activities and (iii)
availability ofrecjuisite data. For example, in USA, about
seventy-one divisions and sub-divisions are used to
classify the national output, in Canada and Netherlands,
classification ranges from a dozen to a score and in
Russia, only half-a-dozen divisions are used. According
to the CSO publication, If fleen sub-categories are
currently used in India. After the output is classified
under the various categories the value of gross output is
is computed in two alternative ways by:
A. Multiplying the output of each earegory of acctor
by their respective market price and adding them
together.
B. Collecting data regarding the gross sales and
changes in inventories from the account of the
manufacturing firms to compute the value of
GDP. If there arc gaps in data then some
estimates are made to fill the gaps.
2. Estimation of cost of materials and services
used
arid depreciation of physical assets: The next step
in estimating the net national income is to estimate (he
cost of production including depreciation. Estimating
cost of production is, however, a relatively more
complicated and difficult task because of non-
availability of adequate and requisite data. Much morc
difficult task is to estimate depreciation since it
involves both conceptual and statistical problems. For
this reason, many countries adopt faclorincome
method for estimating their national income. However,
countries adopting net-product method find some
means to calculate the deductible cost. The costs are
estimated either in absolute terms (where input data
are adequately available) or as an overall ratio of input
to the total output. The general practice in estimatmg
depreciation is to follow the usual business practice of
depreciation accounting. Traditionally, depreciation is
calculated at some percentage of capital, permissible
under the tax-laws. In some estimates of national
income, the estimators have deviated from the
traditional practice and have instead estimated
depreciation as some ratio of the currenL output of
final goods. FoI1owing a suitable method, deductible
costs including depreciation are estimated for each
sector. The cost estimates are then deducted from the
sectoral gross output to ohtain the net sectoral
products. The net sectoral products are then added
together. The total thus obtained is taken to be· the
measure of net nationa I products or national income
by product method.
3. Deduction of these costs and depreciation from gross value to
obtain the net value of domestic product: Net value of domestic
product is often called the value added or income product.
Income product is equal to the sum of wages, salaries,
supplementary labour incomes, interest, profits, and net rent paid
or accrued.
Factor-Income Method
This method is also known as income method and factor-share
method. factorincome method is used when national economy is
considerl:d as a combination of factor-owners and users. Under this
method, the national income is calculated by adding up all the
inconlcs accruing to the basic factors of production used in
producing the national product. Factors of production are c1assi ficd
as land, labour, capital and organisation. Accordingly,
National income = Rent + Wages + Interest + Profits
However, it is conceptually very difficult in a modern economy to
make a distinction between earnings from land and capital and
between the (;arnings from ordinary labour and organisational
efforts including entrepreneurship. Therefore, for estimating
national income factors of production arc broadly grouped as labour
lInd capital. Accordingly, national income is supposed to originate
from two primary factors, viz., labour and capital. However, in some
activities, labour and capital are jointly supplied and it is difficult to
separate labour and capital from the total earnings of the supplier.
Such incomes are termed as mixed incomes. Thus, the total factor-
incomes are grouped under three categories:
Labour incomes
Capital income
Mixed incomes.
Labour Income: Labour incomes included in the national income
have five components:
Wages and salaries paid to the residents of the country
including bonus, commission and social security payments.
Supplementary labour incomes including employer's
contribution to social security and employee's welfare funds
and direct pension payments to retired employees.
Supplementary labour incomes in kind such as free health,
education, food, clothing and accommodation.
Compensations in kind in the form of domestic sr-rvants and
other free ofcost services provided to the employees arc
included in labour income.
Bonuses, pensions, service grants are not included in labour
income as they are regarded as 'transfer payments'. Certain
other categories of income such as incomes from incidental
jobs, gratuities and tips are ignored because of non-availability
of data.
Capital Incomes: According to Studenski, capital incomes include
following Incomes:
Dividends excluding inter-corporate dividends
Undistributed profits of corporation before-tax
Interests on bonds, mortgages and savings deposits
(excluding
interests on bonds and on consumer credit)
Interest. earned by insurance companies and credited to the
insurance policy reserves
Net interest paid by commercial banks
Net rents from land and buildings including imputed net rents
on owneroccupied dwellings
Royalties
Profits of government enterprises.
The data for the first two incomes is obtained from the firms'
accounts submitted for taxation purposes. There exist difference in
definition of profit for national accounting purposes and taxation
purposes. Therefore, it is necessary to make some adjm.ments in
the income-tax data for obtaining these incomes. The income-tax
data adjustments generally pertain to (i) Excessive allowance of
depreciation made by tax authorities, (ii) Elimination of capital
gains and losses since these do not reflect the changes in current
income, and (iii) Elimination of under 0,' overvaluation of
ir:ventories on book-value,
Mixed Income: Mixed incomes include income from (a) fanning
(b) sole proprietorship (not included ,Ilnder profit or capital income)
(c) other professions such as legal and l.ledical practices,
consultancy services, trading and transporting. Mixed income also
includes incomes of those who earn their living through various
sources such as wages, rent on own property and interest on own
capital.
All the three kinds of incomes, viz., labour incomes, capital
incomes and Inixed incomes added together give the measure of
national income by factorincome method.
Expendit4re Method
The expenditure method, is also known as final product method.
This method is used when national economy is viewed as a
collection of spending units. It measures national income at the final
expenditure stages. In other words, this method measures final
expenditure on 'GDP at market prices' at the stage of disposal of
GDP during an accounting year. In estimating the total national
expenditure, any of the following two methods are followed:
First method: Undcr this mcthod all the 111011';y cxpcnditurc
III IIlllrkc( prkc arc computed and added up to arrive at total
national expenditure. The items of expenditure which are
taken into account under the first method are (a) private
consumption expenditure, (b) direct tax payments, (c)
payment? to the non-pro;it-making institutions and charitable
organisations like schools, hospitals and orphanage, and (d)
private savings.
Second Method: Under this method the value of all the
products finally disposed of are computed and added up to
arrive at the total national expenditure. Under the second
method, the following items are considered

Treatment of Net Income from Abroad
Net Factor Income From Abroad (NFIA); We have so far
discussed the methods of measuring national income of a
'closed economy'. However, most modem economics are 'open
economy'. These open economics exchange goods and
services with rest of the world. In this exchange of goods and
services, som\: nations make net income through foreign trade
through exports while some lose their income to the foreign
nations through imports. These incomes are called as Net
Factor Income from Abroa:d (NFIA). The net earnings or losses
in foreign trade affect the national income. Therefore, in
measuring national income the net results of external
transactions are adjusted to the total national income arrived
through any of the three methods. The total income from
abroad is added and net losses to the foreigners are deducted
from the total national income. All the exports of merchandise
and of services such as, shipping, insurance, banking, tourism
and gifts are added to the national income. On the contrary, all
the imports of the corresponding items are deducted from the
value of national output to arrive at the approximate measure
of national income.

Choice of Methods
As discussed above, there are standard methods of measuring the
national incOJ11I.: such as net output method, factor-income
method and expenditure method. 1\11 the I three methods would
give the same measure of national income, provided rcquisitc data
for each method arc adequately available. Therefore, any of the
three methods can be adopted to measure the national income.
However, not all the methods arc suitable for all economies and
purposes. Hence, the problem of choice of method anses.
The two main considerations on the basis of which a particular
method is chosen are:
The purpose of national income
analysis
Availability of necessary data.
If objective is to analyse the net output, then the net output
method would be more suitable. In case, objective is to analyse the
factor-income distribution then, suitable method would be income
method. If objective at hand is to find out the expenditure pattern
of the national income then the expenditure method is more
suitable. However, availability of adequate and appropriate data is
relatively more important considerations in"selecting a method of
estimating national income.
However, the most common method is the net output method
because of the following reasons:
It requires classification of economic activities and output,
which is much easier to classifY than the income or
expenditure.
The most common practice is to collect and organise the
national illcom!.; data by the division of economic activities.
Therefore, easy availability of data on economic activities is
the main reason for the popularity of the .output method.
However, it should he borne in mind that no single method can
give an accurate measure of national income. This is because no
country's statistical system provides the total data requirements
for a particular method.
The usual practice is therefore, to combine two or more methods
to measure the national income. The combination of methods again
depends on the nature of required data and the sectoral breakdown
of the available data.
Measurement of National Income in India
In India, a systematic measurement of national income was first
attempted in 1949. Earlier, some individuals and institutions made
many attempts. Dadabh'\i Narojoji made the earliest estimate of
India's national income in 1876 for the year 1867-68. Since then,
mostly the economists and the government authurities made many
attempts to estimate India's national income.
These estimates differ in coverage, concepts and methodology
and they are not comparable. Besides, earlier estimates were made
mostly for one year, only some estimates covered a period of 3-4
years. It was therefore, not possible to construct a consistent series
of national income and assess the pcrforniance of the economy over
a period of time. It was only in 1949 that National Income
Committee (NIC) was appointed with PC. Mahalanobis, as its
Chairman and D.R. Gadgil and V.K.R.V. Rao as its members. The NIC
not only highlighted the limitations of the statistical system that
existed at that time but also suggested ways and means to improve
data collectiol1' systems. On the recommendation of the
Committee, the Directorate of National Sample Survey was set up to
collect additional data required for estimating national income.
Besides, the NIC estimated country's national income for the period
from 1948-49 to 1950-52. In its estimates, NIC also provided the
methodology for estimating national income, which was followed
until 1967.
After the NIC, the task of estimating national income was taken
over by the Central Statistical Organisation (CSO). Until 1967, the
CSO followed the methodology laid down by the NIC. Thereafter, the
CSO adopted a relatively improved methodology and procedure,
which had become possible due to increased availability of data.
The improvements pertain mainly to the industrial classification of
the activities. The CSO publishes its estimates in its publication
Estimates of National Income.
Methodology
Currently, output and income methods are used by the CSO to
estimate national income of our country. The output method is used
for agriculture and manufacturing sectors, i.e., the commodity
producing sectors. Income method is used for the service sec(ors
including trade, commerce, transport and governmeni' services. In
its conventional series of national income statistics from 1950-51 to
1966-67, the fSO had categorised the income in 13 sectors.
However, in the revised series, it had adopted the following 15
break-ups of the national economy for estimating the national
income.
(i) Agriculture (ii) Forestry and logging (iii) rishing. (iv) Mining
and quarrying (v) Large-scale manufacturing (vi) Small-scale
manufacturing (vii) Construction (viii) Electricity, gas and water
supply (ix) Transport and communication (x) Real estate and
dwellings (xi) Public Administration and Defence (xii) Other services
and (xiii) External transactions. The national income is estimated at
both constant ar.d current prices.
Growth and Composition of India's NaConallncome
The following Tables present the growth and change in composition
of India's national income, both at factor cost and current prices.
Table. 6.1 presents the decennial trends in national income
aggregates like GDP, GNP, NDP, NNP, Netfactor income from
abroad, capital consumption and indirect tax and subsidies. Table
6.2 presents the change in the composition of national income
classified under five broad categories. Table 6.3 presents the
decennial annual average growth rate of GNP and GDP at constant
prices. It can be seen from Table 6.2 that the composition of India's
national income has changed considerably over the past four
decades. The share of ~griculture has declined from 55.8% in GDP
in 195051 to 31.3% in 1994-95 and that of industrial sector
increased from 15.26 to 27.5 % during th; same period.

Inflation and Deflation
The term 'inflation' is used in many senses and it is difficult to give
a generally accepted, precise and scientific definition of the term.
Popularly, inflation refers 1O a rise in price level. Kemmerer states,
"Inflation is too much money and deposit currency that is too much
currency in relation to the physical volume of business being
done." This is what Coulburn also means when he defines inflation
as, "Too much money chasing too few goods". According to T.E.
Gregory, inflation is "abnormal increase in the quantity of money".
The implication in these definitions is that prices rise due to an
increase in the volume of money as compared to the supply of
goods. This is the quantity approach to the rise in the price level.
However, it should be noted that prices may rise due to other
factors also such as rise in wages and profits. Besides, there can be
an inflationary pressure on prices without actually rising of the
prices.
Keynesian Definition
Kl:YlH:S rdales inl1ation to a price level that comes into existence
after the stage of full employment. While, the quantity approach
emphasises the volume of money to be responsible for rise in the
price level. Keynes distinguishes between two types of rise in
prices (a) rise in prices accompanied by increase in production (h)
rise in prices not accompanied by incrl:ase in production. If an
economy is working at a low level, with a large number of
unemployed men and unutilised resources then expansion of
money or some other. factors leading to an increase in demand will
result not only in a rise in the price level but also rise in the volume
of goods and services in an economy. This will continue until all
unemployed men tind employment arid capital and other resources
are more fully utilised, i.e., the stage of full employment. Beyond
this stage, however, any increase in the volume of money or rise in
demand will lead to a rise in prices but lIO corresponding rise in
production or employment.
Keynes states that the initial rise in prices up to the stage of full
employment is a good thing far the country 'since there is an
increase in. output and employment. Reflation or partial inflation is
used to designate such a rise in the price level. The rise in prices
aller the stage of full employment is bad far the country since
there is no corresponding increase in production or employment.
Inflation is used to express such a rise in the price level. Therefore,
inllation refers
to a rise in the price level after full employment has been attained.
(
According to Keynes, "inflation" can be applied to an
underdeveloped country like India where unemployment of men
and resources exist side by side with inflationary rise in prices. This
is due to the existence of bottlenecks, such as limited amount of
capital, machinery, transport facilities and absence of technical
know-how. As a result of these bottlenecks and shortages, a rise in
the price level may not lead to increase output beyond a certain
stage, even though the country may not have reached the stage of
full employment. We can distinguish between three kinds of
inflation on the basis of their causes, viz., demand-pull, cost-push
and sectoral inflation.
Demand-pull Inflation
The most common cal;lse for inflation is the pressure of ever-rising
demand on a stagnant or less rapidly increasing supply of goods
and services. The expansion in aggregate demand may be due to
rapidly increasing private investment or expanding government
expenditure for war or economic development. At a time whe.n
demand is expanding and exerting pressure on prices'cattempts
are made to expand production. However, this may not be possible
either due to nonavailability o(uqemployed resources or shortages
of transport, power, capital and equipment. Expansion in aggregate
demand, after the level of full employment, results into rf~e in the
price level. In a developing economy I ike India, resources are used
for growth, for creating fixed assets and production of consumer
goods. Necessarily, large expenditure will create. large money
income and large demand but without a corresponding increase in
supply of real output.
We should emphasise here the role played by deficit financing
and increase in money supply on the level of prices in a developing
COU1Hry. Ollen. the government of a developing country resorts to
deficit spending Lo finance economic development i.e., borrowing
from the central bunk und cOllllllercial banks, which, in turn, leads
to increase in money supply in the country. This exerts a strong
pressure on the level of prices. An increase in" foreign demand for
the exports of a country may also raise the price level in a country.
Expansion in foreign demand aM consequent expansion in exports
will raise income of the people. This will push up demand for goods
and services within a country. In case the additional money income
is used to buy imports or is hoarded then it will not have inflationary
effect in the country. Thus, inflationary pressure is built by
increasing aggregate demand in excess of the available resources.
The increase in aggregate demand can be due to increase in
government expenditure or increase in private investment and
private consumption or release of pent up demand of consumers
immediately after a war or increase in exports and so on. Deficit
financing and increase in money supply further aggregate the
situation by boosting demand still further. In all these cases,
inflation is the result of demand-pull factors. It must be emphasised
here that demand-pull inflation cannot be sustained unless there is
increase in money supply.
Cost-push Inflation
In certain circumstances, prices are pushed up by wage increases,
forced upon the economy by labour leaders under the threat of
strike. Costs can also be raised by manufacturers through a system
of fixing a higher margin of profit. The common man generally
blames profiteers, speculators, hoards and others for pushing up the
costs and prices. Again, the government is responsible for raising
the costs by imposing new taxes and continuously raising the tax
rates of existing commodity. Therefore, rising rates of commodity
taxes, in a sellers market, will enable the producers to raise the
prices by the full amount of taxes. Under conditions of rising prices,
business and industrial units find it easy to pass on the burden of
higher wages to the consumers by raising the prices. 1 II us, rise in
wages; profit margin and taxation are responsible for cost-push
inflation.
In periods when wages, prices and aggregate demand are all
rising and creating an inflationary situation, it is d-ifficult to find out
active and passive factor. In many cases, it is neither demand-pull
inflation nor cOSt-push inflation, but it is a combination of both.
However, it is possible and often useful to separate the dominant
factors. If aggregate de~and is responsible for the inflationary
situation, it may persist so long as excess demand persists and in
the extreme case, it may develop into hyperint1alion cwn thoug.h

Ill,'lli",h, aimcd at controlling aggregate dCllland then we have
demand-pull inllation. Un thc other hand, if wages and prices
continue to rise even whcn demand ceases to grow, we have cost-
push int1ation.
Sectoral Demand Shift Theory of Inflation
Under dcmand-pull inflation, we have shown how expansion in
aggregatc demand without a proportionate increase in the supply of
goods and services leads to an inflationary situation. However, it is
not necessary to have a general increase in demand to bring about
inflationary pressure. Sometimes, the increase in demand may be
confined to some sector of the economy and this increase in
demand and the consequent rise in the price in a particular sector
may spread to other sectors Suppose the demand for agricultural
goods rises because of inadequate supplies of' these goods. There
would be a consequent rise in the price' of agricultural goods. Thus,
the rise in prices spreads to all other sectors in the economy,
through rise in the prices of raw materials and wages. The rise in
prices in the agricultural sector may push up prices in the industrial
sector. Therefore, the inflationary rise in the price level is due to
sectoral shifts in demand.
The "sectoral demand" emphasises the fact that prices are
highly flexible upwards but relatively rigid downwards, for example,
there may be rise in prices in the agricultural sector where there is
scarcity whereas price stability in the industrial sector where there ..
is an excess supply. However, in course of time, prices all over the
economy will assume an upward trend. The "sectoral demand" is
also useful to explain the simultaneous existence of inflation and
recession, i.e., inflation in some sectors and recession in certain
other sectors. Industries coming under inflationary pressure will
experience persistent rise in price but industries suffering from
recession may not experience a fall in the price level. Modern
economists have coined the word "Stagflation" to refer to this
situation in which stagnation in some sectors of the economy is
present while other sectors are subject to a highly inflationary
situation.
Other Classifications of Inflation
Open Inflation: Inflation is said to be open when prices rise
without any interruption. It may ultimately end into hyper-
inflation.
Suppressed inflation: Suppressed inflation refers to a situation
in which price level is not allowed to rise with the use of price
controls and rationing, even though conditions exist for rise in
the price levcl. The price level may rise when the control
measures are lifted.
Suppressed inflation results in (a) postponement of present
demand to a future date (b) diversion of demand from one kind
of goods to another, i.e., from those goods which are subject to
price control. and rationing to those whose prices are
uncontrolled and non-rationed. Suppressed inflation has many
dangers. First, it creates administrative problems of controls
and rationing. Secondly, it leads to corruption of the price
control administration and risc of hlack IIlarkcls. Thirdly. it
CHllses 1I1leCOIIOlllic diversion of productive resources from
essential goods industries whose prices are· tixed or
controllable to those . industries whose products are less
essential but prices are uncontrollable.
Creeping, Running and Galloping Inflation: In the initial stage of
rise in the price level, prices may be rising slowly and this is
referred as creeping inflation. In course of time, the rise in the
price level becomes more marked and alarming. This is
referred as running inflation. Ho.vcver, when the rise in the
price level is staggering and extremely rapid, it is often
referred to as galloping inflation or hyper-inflation, which a
country should avoid at all costs.
Consequences of Inflation on Production and Employment
Inflation affects both production and distribution of income in a
country. Inflationary rise in prices may not affect adversely the
production of national income. When all aV2.ilabk men and
materials are employed then the stock of real wealth in the form of
land and building is not diminished and the total real income or
output available for distribution between the different sections of
people remains the same. However, in course of time when inflation
has gone beyond a certain limit, it may lead to reduction in
production and increase in unemployment due to the following
reasons:
Firms may find it profitable to hoard rather than produce
and sell
Agriculturists may refuse to sell their surplus stocks in the
hope of
getting higher prices
Production may be interrupted by bitter labour strikes.
Therefore, beyond a certain stage, surplus stocks accumulate,
profits decline and invcstmcnt. prodllClillll and incomc rail and
lIncmpl()ymcnll\l·i~l's.
On Distribution of Income
It is true that in times of general rise in the price level, if all groups
of prices, such as agricultural prices, industrial prices, prices of
minerals, wages, rent and profit rise in the same direction and by
the same extent, there will be no net effect on any section of people
in the community. For example, if the prices of goods and services,
which a worker quys rises by 50 per cent and if the wage of the
worker also rises by 50 per cent then there is no change in the real
income of the worker, i:e., his standard of living will remain
constant. However, in practice, all prices do not move in same
direction and- by saine percentage. Hence, some classes of reople
in the community are affected more favourably than others. This is
explained as follows:
Producing Classes: All producers, traders and specu!.ators
gain during
inflation because of the emergence of windfall profits. The
prices of
goods rise at a far greater rate than costs of production
whereas wages,
interest rates and insurance premium are all mere or less fixed.
Besides, the producers keep such assets, as commodities, real
estate, etc., whose prices rise much more than the general
level of prices. Thus, the producing and trading classes gain
enormously during an inflationary period. However, farmers
may gain only if their output is maintained or increased.
Fixed Income Groups: Inflation is very severe on those who arc
living on past savings, fixed rents, pensions and other fixed
income groups called as the middle classes. Those persons who
are working in government and private concerns find their
money incomes more or less fixed while the prices of the goods
and services, which they buy are rising very rapidly. Those with
absolui~ly fixed incomes derived from interest and rent-known
as the renter class, realise that their money income is
absolutely worthless and their past savings have insignificant
value in front of high prices. In fact, the worst sufferers in
inflation are the middle classes who are considered as the
backbone of any stable society.
Working Classe~: During inflation, the working classes also
suffer, firstly because wages do not rise as much as the prices
of those commodities and services, which the workers buy.
Secondly, there is also time lag between rise in th~.price level
and wages. However, these days, many groups of workers are
organised in trade unions and their wages rise simultaneously
with rise, in the cost of living. Therefore, it can be presumed
that organised workers may not suffer· much during inflation.
However, there are many grOlIl)S of workers who arc not
organised for example, the agricultural labourers, who find no
way of pushing up their wages in the face of rising prices and
cost of living.
Inflation, lilus, brings shi fts in the distribution of incomc hctwccn
di !Tcrellt sections of people. The producing classes such as
agriculturists, manufacturers and traders gain at the expense of
salaried and working classes. The rich become richer and the poor
becomes poorer. Thus, there is a transfer of income from poor to
rich classes. Inflation, therefore, is unjust. Besides, those who are
hard hit by inflation are the young, old, widows and-small savers,
i.e., all those who are unable to protect themselves. But the most
unfortunate thing is that monetary arid fiscal authorities which are
entrusted with the task of maintaining price stability are often
responsible for creating inhltionary conditions, for example, a
country at war resorts to printing of currency notes as one of the
methods of financing war. Similarly, the government of a developing
economy may resort to deficit financing as . one of the methods of
financing development projects; In these cases, inflationary finance,
like taxation, brings in additional revenue to the public authorities.
However, taxation cannot destroy an economy except in rare cases
by eliminating whole groups of people. Inflation, on the other hand,
can destroy fixed income group, pauperise the middle classes and
destroy the very foundations of an economy. No wonder inflation
has been termed as "a species of taxation, cruellest of all" and
"open robbery". Inflation, particularly the hyperinflation of the
German type, will therefore endanger the very fow(jations of the
existing social and economic system. It will create a sense of
frustration distrust, injustice and discontent and may force people
to revolt against the government. It is, therefore, "economically
unsound, politically dangerous and morally indefensible". Therefore,
it should be avoided and even if it occurs it should be controlled.
Control of Inflation
Inflation should be controlled in the beginning stage, otherwise it
wiil take the shape of hyper-inflation which will completely run the
country. The different methods used to control inflation are known
as anti-inflationary measures. These measures attempt mainly at
reducing aggregate demand for goods and services on the basic
assumption that inflationary rise in prices is due to an excess of
demand over a given supply of goods and services. Anti-inflationary
measures are of four types:
Monetary policy
Fiscal policy
Price controlnnd mtioning
Other methods
Monetary Policy
It is the policy of the central bank of the country, which is the
supreme monetary and banking authority in a country. The
central bank may use such methods as the bank rate, open
market operations, the reserve ratio and selective controls in
order to control the credit creation operation of commercial banks
and thus restrict the amounts of bank deposits in the country.
'this is known as tight money policy. .\ Monetary policy to control
inflation is based on the assumption that a rise in prices is due to
a larger demand for goods and services, which is the direct result
of expansion of bank credit. To the extent this is true, the central
bank's policy wi}1 be successful.
Fiscal Policy
It is the policy of a government with regard to taxation,
expenditure and public borrowing. It has a very important
influence on business and economic activity. Taxes determine the
size or the volume of disposable income in the hands of the
public. The proper tax policy to control inflation will avoid tax
cuts, introduce new taxes and raise the rates of existing taxes.
The purpose being to reduce the volume of purchasing power in
the hands of the public and thus reduces their demand. A
precisely similar effect will be achieved if voluntary or compulsory
savings are increased. Savings will reduce current demand for
goods and thus reduce the inflationary rise in prices.
As an anti-inflationary measure, government expenditure
should be reduced. This .indicates that demand for goods and
services will be further reduced. This policy of increasing public
revenue through taxation and decreasing public expenditure is
known as surplus budgeting. However, there is one important
difficulty is this policy. It may be easy to increase revenue in times
of inflation when people have more money ineome !:Jut difficult to
reduce public expenditure. During war as well as during a period
of development expenditure it is absolutely impossible to reduce
the planned expenditure. If the government has already taken up
a scheme or a group of schemes, it is ruinous to give them up in
the middle.; Therefore, public expenditure cannot be used as an
anti-inflationary measure. Lastly, public debt, i.e., the debt of the
government may be managed in such a way that the supply of
money in the country may be controlled. The government should
avoid paying back any of its previous loans during inflation so as
to prevent an increase in the circulation of moneY: Moreover, ifthe
government manages to get a surplus budget it should be used to
cancel public debt held by the central bank. The result will be anti-
inflationary since money taken from the public and commercial
banks is being cancelled out and is removed from circulation. But
the problem is how to get abudgct surplus, \vhich is extremely
difficult, if not impossible.
Price Control and Rationing
This is the most important and effective method available during
war particularly oecause both monetary and fiscal policies are more
or less useless during this period. Price control implies the
establishment to legal upper limits beyond which prices of particular
goods should not risco The purpose of rationing, on the other hand,
is to distribute the goods in short supply in an equitable manner
among all people, irrespective of their wealth and social status.
Price control and rationing g.enerally go together. The chief
objection behind use of this method to fight inflation is that they
restrict the freedom of the consumers and thus limit their welfare.
Besides, its success depends on administrative efficiency, which in
many underdeveloped countries is very low.
Other Methods
Another important anti-inflationary device is to increase the
supply of goods through either increased production or
imports. Production may be increased by shifting factors of
production from the production of less inflation sensitive
goods, which are in comparative abundance to the
production -of those goods which are in short supply and
which are inflation-sensitive~ Moreover, shortage of goods
internally may be relieved through imports of inflation
sensitive goods, either on credit or in exchange for export of
luxury goods and other non-essentials.
A word may be added about the measures to control cost-
push inflation. It is suggested that wages, salaries and profit
margins should be controlled and fixed through a system of
income freeze. Business units may particularly welcome
wage freeze. However, wage freeze is not so easy or just,
unless trade unions agree to the proposal and there is also
freezing of prices. At the same time, the Government should
not raise the rates of commodity taxes. Thus, it is difficult to
control c'ost push inflation through controlling wages and
other incomes. The best method is to bring a rapid increase
in production, which will automatically check prices and
wages also.
Inflation in an: Underdeveloped Economy
Basically, inflation is supposed to occur after reaching the stage of
full employment, for till that stage is reached an increase in
effective demand and price level will,be fr)lowed by an increase in
output, income and employment. It is after the stage of fuli
employment when all men are employed that a rise in the price
level will not be accompanied by an increase in production and
employment. Theoret.ically, therefore, it is not possible to imagine
an inflationary situation existing side by side with full employment.
It is in this context that the question of inflation in an under
developed country like India, which has both widespread
unemployment and underemployment is raised.
Bottleneck Inflation
It is interesting to observe that Keynes himself visualised the
possibility of an inflationary situation even before full employ·.lent
was reached. Such: a situation can arise even in advanced
countries, if there are difficulties in perfect G\lasticity of supply of
goods and services. It is possible that full employment is not
reached but even then, there is no scope for increased production.
The factors responsible for imperfect ela<;ticity of supply are law of
diminishing returns, absence of homogeneous factors and
unemployed resources, which cannot be used to increase
production. All these factors are lumped together and are known as
bottlenecks. As monetary demand increases with the increase in
money supply, supply of goods does not increase in proportion, due
to imperfect elasticity. The difficulties or handicaps, which prevent
supply from increasing in the face of rising demand, are known as
bottlenecks. The result is that the cost of production is pushed up
and price level is raised. Apart from these, other bottlenecks are as
follows:
Market imperfections' in underdeveloped countries, such as
imperfect knowledge on the part of producers and consumers,
mobility of factors, divisibility of factors and lack of
specialisation. All these are responsible f9r inefficient use of
resources. There is, thus, imperfect elasticity of supply in an
underdevelopeJ country.
Underdeveloped countries face shortage of technical labour,
capital, equipment and transport and power facilities.
Therefore, these countries are unable to grow
becauserofthese.bottlenecks.
Unemployment and underemployment are extensively present
in an underdeveloped country. The existence of unemployment
in the advanced country helps increase' output, whenever
there is increased demand. However, this is not so in a country
like India with a large magnitude of disguised unemployment
and open unemployment. According to or.V.K.R.V. Rao,
disguised unemployment is not so resrollsive to an increase in
effective demand.
Underdeveloped countries generally have II high mnrginul
propensity to consume. or.Rao believes that this factor
prevents an increase in the supply of goods and services. For
instance, in the field of agriculture, increased production may
be _ consumed at home ~nd, therefor;-:, less may be
forthcoming to the market.
A special feature of underdeveloped countries is that a large
volume of primary production is exported. Therefore, the
supply available for home consumption is reduced. The
problem of inflationary rise in prices i~ worsened whenever the
income earned from exports is spent on domestiC goods and
not on imports.
Since World War II, many of the underdeveloped countries have
started resorting to extensive borrowing from the banks and
deficit fi.nrmcing with the idea of speed ing up economic
develop!nent. For one thing, much of this expenditure is on
social and ccor:omic overheads, such as education, transport
and powcr and on capital goods industries such as
development of iron and steel industry. This implies that there
is an increase in the production of consumption goods.
Therefore, the volume of purchasing power with the general'
public is increased, resulting in increased demand for
consumption goods.
All these factors explain the existence of inflationary pressure in
all underdeveloped country, even though the stage of full
employment has not been' reached. The existence of bottlenecks
such as· shortage of technical know-how and scarcity of capital
equipment has worsened the various problems related to
underdeveloped countries. It is, therefore, correct to use th~
concept of inflation even in underdeveloped countries, provided we
remember the existence of special bottlenecks.
Deflation
I I' prices an; abnormally high, it is indeed desirable to have a fall in
prices. Such a fall in the price level is good for the community, as it
will not lead to a fall in the level of production or employment. The
process designed to reverse the inllationary trend in prices, without
creating unemployment, is generally known as disinflation. But if
prices fall from the level of full employment, then income and
employment will be adversely affected and this situation is termed
as deflation. The foll0wing Figure 6.1. shows if the price level
continues to rise even after the stage of full employment has been
reached, it is cnlled intlntiol\. Decline in prkt' level as a result of
anti-inl1ationary measures is known as disinflation. If prices litll

supply. uel1l1tion implies dcticiency of dcmand to lift what is
supplied. While inflation means rise in money incomes, deflation
stands for fall in money incomes.
Effects of Deflation
The following are the adverse effects of deflation:
On production: Deflation has an adverse effect on the level of
production, business activity and employment. During
deflation, prices fall due contracting demand for goods and
services. Fall in price results in losses' and sometimes forcing
many firms to go into liquidation. In the face of declining
demand for goods, firms arc forced to close down either
completely or leave part of their plants idle. Thus, production
of income is curtailed and unemployment is increased. 111is
is a serious defect of deflation, as compared to inflation in
which normally there may not be an adverse effect on
production and employment.
On distribution: Deflation adversely affects distribution of
income too. In the first place, producers, merchants and
speculators lose badly during this period because price~ of
their goods fall at a far greater rate than their costs, most of
which tend to be fixed or sticky. Besides, most of these people
are debtors who use borrowed funds in their businesses. They
have to repay their debts in money, which has now more value
because of deflation. For some debtors, who do not have
adequate means to repay their loans had to go into liquidation.
Deflation implies fall in price level or rise in the value of
money: All those who have fixed incomes will be far better off
because their money income is fixed. In other words, the fixed
income groups will enjoy a rise in their real income. Therefore,
it is assumed that salaried persons and wage C<llners wi II
bcnefit by denatioll. Ilowcvcr, this is not completely true since
there is increasing unemployment. Therefore, only those who
are successful in keeping their jobs will be able to gain from
the rise in the value of money. As a matter of fact, during
deflation, there is great suffering and mystery all round and
millions of families are literally thrown onto the streets to make
their living through begging. The only group of people who
may really gain is that small minority, known as the renter
class who get their income by way of fixed interest and rents.
Methods of Control
Anti-deflation measures are the opposite of those, which are used to
combat inflation. Monetary policy aimed at controlling deflation
consists of using the discount rate, open-market operations and
other weapons of control available to the central bank of a country
to raise volume of credit of commercial banks. This policy is known
as cheap money policy. This is based on an idea that with the
increase in the volume of credit, there will be an increase in
investment, production and employment. However, monetary policy
is basically weak, for it assumes that the volume of credit can be
expanded by the central bank. This may not be so, because even
when commercial banks are prepared to lend more to businesses to
enable them to expand their investment, the latter may not be
willing to do so for fear of possible failure of their investments.
Fiscal policy to fight deflation is known as deficit financing, i.e.,
expenditure in excess of tax revenues. On one hand government
attempts to reduce the level of taxation to provide large amount of
purchasing power with the public. While, on the 'other hand, the
government increases its expenditure on public work programmes
such as irrigation, construction of roads and railways. By this
programme government will (:I) provide employment for those who
may be thrown out of employment in the private sector, (b) add tei
national wealth, and (c) counteract the deficiency of private demand
for goods and services. The budget deficit can be financed through
borrowing from the public of their idle cash balances or banks. The
basic idea of fiscal policy is to expand demand for goods or to
counteract the decline in private demand. Therefore, fiscal policy is
the most important policy for economic stabilisation.
Other measures to control deflation include price support
programmes, i.e., to prevent prices from falling beyond certain
levels and lowering wage and other costs to bring adjustment
between price and cost of production. Price support programme has
been extensively used in the USA in recent years but it is very
difficult to carry it through. The government will have to fix the
prices below which the commodities will not be sold and undertake
to buy the surplus stocks" It is difficult for the government to secure
the necessary funds for such transactions as well as to devise ways
and means to dispose of the surplus stocks in other countries.
Therefore, the best solution for deflation is to have a ready
programme of public works to be implemented as and when
unemployment makes its appearance.
Compariso!between Inflation and Deflation
Inflation is rise in prices unaccompanied by increase in employment,
while deflation is fall in prices accompanied by increasing
unemployment. Inflation distorts the distribution of income between
different groups of people in' the country in such an unjust manner
that the rich gain at the expense of the poor. Deflation, on the other
hand, reduces national income through contraction of production
and increas~ in unemployment.
Inflation is unjust and demoralising. Deflation, on the other hand,
inflicts on the people the harsh punishment of general
unemployment. There exist factories and mills on one hand and
workers ready to \';ork on the other hand, however, the whole team
remaining idle, on the other. Inflation at least implies that all factors
are employed in some way or the other. There is one more reason
why deflation is worse than inflation. Inflation can be controlled
except occasionally it gets out of control. However, deflation, if once
started, injects so much pessimism into businessmen and bankers
that it is highly difficult to control. However, there is nothing to
choose between the two and the proper objective should be to aim
at economic stabilisation at the level of full employment.
Inflationary and Deflationary Gaps
Keynes developed the concept of inflationary gap'. InfliJtionary gap
refers to, "excess of anticipated expenditures over the availahle
output al base pril'.c.~." Inflationary gap occurs when there is an
excess of demand over available supplies. Let us take a simple and
hypothetical example to illustrate the eme~gence of inflationary
gap.
During 'a period of war, the volume of money expenditure in a
country increases, because or" the government's expenditure on
the armed forces and armaments. Increased government
expenditure resulting in increased income with the community will
lead to increased consumption expenditure and investment. The
disposable income of the community, which constitutes aggregate
demand for goods and services, is as follows:
(Rs. Crores)
1. National income received during a given year:
20,000
2. Taxes paid to the government: 5,000
3. Gross disposable income (I -2): 15,000
4. Saving by the community at 10% oft',e income: 1,500
5. Net disposable income with the community:
13,500
The net disposable income with the people represents aggregate
demand for goods and services ofa community. As against the
aggregate demand, the aggregate supply comes from gross
national product. However, not all output is available for the
community. The government diverts some resources such as food
grains, cloth, for war purposes, then the total output available for
civilian consumption is less than the gross national pro,duct (GNP).
For instance,
(Rs. CIJres)
1. National product (real income): 20,000
2. Appropriated for war purposes: 8,000
3. Available for civilian consumption: 12,000
Now the net disposable income, which the community will like to
spend is Rs. 13,500 crores but the available output for civilian
consumption is only Rs. 12,000 crores. There is excess of demand
o'Ver available supply ~') tne extent of Rs. 1,500 crores, which is
referred to as the inflationary gap. The basic fact is that so long as
the amount of disposable income with the people and the volume of
goods and services available for them are the same, there will be
price stability; but whcn thL~ forillcr is Illore' thnllthe lillieI', nn

Though Keynes assoeialed un inflationary gap with war, we
cun I\lso spcak of inflationary gap during periods of economic
development Since 1951, India has undertaken economic
development, financed partly through created money. As a
result, there has been enormous increase in money expenditure
and money income but without a corresponding increase in the
volume of consumptioll goods (part of the increase in production
has been in capital goods). Besides, there is a ~' time interval or
gap between investment and output of goods and services.
Naturally, there is excess demand resulting in inflationary
pressure on the general price level. Inflationary gap can be
illustrated by using the Keynesian concepts of aggregate
demand and aggregate supply, The following Figure 6.2 shows
the' inflationary gap.
In Figure 6.2, the horizontal axis represents volunie of income
and the vertical axis represents volume of total expenditure (C +
I + G). The 450 vertical axis represents equilibrium line of Y = E
and line C + I + G represents the total expenditure. At point E,
the economy is in equilibrium because at E the supply of goods
and services or real income (OY) is equal to the demand for them
at EY. Therefore, OY is' regarded as equilibrium income as well as
full employment income at current prices.
Suppose, the Government increases its expenditure either for war
or development purposes, by an amount equal to EA. Then the new
aggregate demand is shifted upwards and beco~es C' +' l' + G'. C'
of- l' -\- G' is parallel to C + r + G line by the amount MEA. The real
output (or income)remains constant at OY but the mOlletary
demand for this output is not EY but Y A, there is, thus. an excess of
demand and equal. to.EA. EA, therefore, represents inflationary
gap, which is responsible for pushing up the price level.
Wiping out Inflationary Gap
The inflationary gap can be wiped out in various ways. Essentially, it
starts with additional expenditure by the government, which in turn
calls for additional expenditure by the community. Through
economy in government expenditure, the excess of aggregate
demand can be reduced. However, this is not always possible in
practice, as government expenditure cannot be cut down during
wartime or period of economic devdopment. To remove this
inflationary gap. various mtlhods can be adopted, such as:
There cun be a rise ill voluntary saving by the community.
The government may use the tax system to mop up the surplus
purchasing power with people; this will reduce C + I by the
same amount as the increase in government expenditure.
The output of goods and services may be increased so as to
absorb the excess demand. In Figure 6.2, such an increase in
real income should be YY1• But, as mentioned already, there is
no scope for such an increase in real income, as the economy
is already at full employment level.
Deflationary Gap
Deflationary gap is the opposite of inflationary gap. If the volume
of goods and services is larger than the aggregate demand for
them, a deflationary gap will arise. Deflationary gap arises when the
C + I of- G line is pushed down to C' + I' + G'. The decline in
demand may be because of reduction in government expenditure or
decline in private investment or fall in private consumption demand.
This is shown in Figure 6.3. OY, = Volume of real income available
for the community
As regards wiping out the deflationary gap, the government
should increase its expenditures or help to raise the expenditure of
the general public. The government can raise its own expenditure
by investing in public works and financing them by borrowing from
banks. The expenditure of the community C + I can be raised by
reducing laxes and other incentives. If the C' + j' + G' is raised to
the original level then the deflationary gap will disappear.
Stagflation
Inflationary gap occurs when aggregate demands exceeds the
available supply and deflationary gap occurs when aggregate
demand is less than the available supply. These are two opposite
situations. However, we may show how deflationary forces follow
inflation, which has not been controlled. For instance, when inflation
goes unchecked for sometimes and priCes reach very high levels,
aggregate demand contracts and slumps follows. Consumption
demand (C) declines because of high price levels. The middle and
lower income groups have to curtail th<f" consumption of many of
the goods. Increase in private investment (I) does not take place
because investors are afraid of future and there is decline in
consumer demand at the height of inflation. In fact, the decline in
consumer demand and private investment will reinforce each other
and create a deflationary situation. Further, un excessive rise in the
price 'level will affect exports adversely and thus create a slu1np in
the export industries as well. It is, thus, possible to visualise a
situation in which inflationary and deflationary pressures are
present simultaneously. The existence of an economic recession at
the height of inflation has been called as stagflation (stagnation +
inflation).
Trade Cycles '
Wesley C. Mitchell, a noted American authority 011 business cycles,
wrote: "Business cycles are a species of fluctuations in the economic
activities of organised communities." The adjective ,'business'
restricts the concept to fluctuations in the activities, which are
systematically conducted on commercial basis. The noun 'cycles'
bars out fluctuations, which do not recur with a measure of
regularity. Mitchell has, thus, described all the important features of
a business cycle admirably. According to him, features of trade
cycle are:
It occurs only in organised communities, which are
money economies.
Refers to fluctuations or changes in business
conditions.
Implies regular and periodical changes in business and
economic activities.
According to Keynes, "A trade cycle is composed of periods of
good trade characterised by rising prices and low unemployment
percentage, alternating with periods of bad trade characterised by
falling prices and high unemployment percentage. "
Characteristics of Trade Cycles
From the above definition, it should ,be clear that trade cy~les is
rhythmic fluctuations of the economy, that is, periods of prosperity
followed by periods of depression. However, the waves of prosperity
and depression need not always be of the same length and
amplitude. Further, trade cycles varied tremendously in magnitude.
Whde some have smaller cyclical fluctuations in economic activity,
others have great intensity of fluctuations. Expansion in some
cycles reaches the full employment level and stays there. However,
in some cycles, the peak is reached even before full employment.
Sometimes, the cyclical fluctuations may be prolonged for one
reason or the other.
The American Economic Association emphasised the following
important characteristics of trade cycle:

The total output and employment Jluctuate by a larger
percentage in durable and capital goods industries than in
non-durable and consumption goods industries.
Large changes in total output, employment and the price
level are normally accompanied by large changes in
currency, credit and velocity of circulation of Illoney.
Prices of manufactures are comparatively rigid while prices of
agricultural goods are normally flexible.
Profits fluctuate by a much larger percentage than other types
of income.
Industries are so inter-connected that fluctuations in one will
be passed on to others also, Thus, cyclical fluctuations affect
all industries.
Cyclical fluctuations tend to be international, in the sense
that prosperity and depression spread from one country to
another through foreign trade,
Phases of a Trade Cycle
Every trade cycle is characterised by two main phases namely, the
upward phase and the downward phase of'the trade cycle. These
two phases further have four or five different sub-phases, such as
depression, recovery, full employment, boom and recession. In
monetary terminology, the same phases . correspond to
depression, deflation, full employment, disinflation and deflation.
The following Figure 6.4 shows· the different stages· of a trade
cycle. FE represents the full employment line-it may be taken as the
dividing line. Above this line, there is business prosperity and boom
and below this line, there is business depression. As a trade eycle is
a continuous phenomenon, it is essential to break it som~where. It
is customary to start at the lowest point of the upward " phase,
namely, the depression.
Depression: During depression, the level of economic activity is
extremely low. The price level is low, profit margins do not exist,
firms incur losses and unemployment is high. Interests, wages
and profits are all low. While all sections in the economy suffer,
some suffer more than others do. For instance, the producers of
agricultural goods suffer badly because the prices of agricultural
goods fall the most during depression. This is due to inability of
the farmers to adjust their output according to the market
demilnd, which is low. The worst hits are the working classes that
suffer heavily because of unemployment. The depression is thus,
a period of great suffering, low income and unemployment.
The phase of recovery: Depression gives place to recovery. There
is revival of business and economic activity. There is greater
demand for goods and services and consequently there is greater
production. Prices, wages, interests and profits all start rising.
Employment increases and so docs the national income. There is
increase in investment, bank loans and advances, velocity of
circulation of money due to more brisk tnide. Through multiplier
and acceleration effects, the economy is proceeding upward
steadily and rapidly. The process of revival and recovery becomes
cumulative. Increased receipts result in increased expenditure
causing further incrcasc in n:ceipts. which in turn, rcsult in further
increased expendllure and so on. The wave of recovery on'ce
initi"ted soon begins to feed upon itself.
The phase of full employment: The cumulative process of
recovery continues until the economy reaches full employment.
Full employment implies that all the available men arc employed.
The economy has reached the optimum level of economic
activity. During this phase, there is an allround economic stability
referring to stability of output, wages, prices and income. Wages,
interests and profits are high, output is highest with the given
technology and employment is maximum. There may be small
percentage of unemployment, but it is not of an involuntary type
but of voluntary and frictional type. The period of full employment
has become the usual goal of most national economic policies.
The phase of boom or inflation: The phase of recovery frequently
ends not in a stable state of full employment o~ prosperity but
further leads to a boom or inflation. Beyond the stage of full
employment, the rise in investment results in increas~d pressure
for the available men and materials and rise in wages and prices.
During this period, there is hectic activity going on everywhere in
the economy such as new buildings come up, new factories are
commissioned and many new trades are started. In a matter of
weeks or months, full employment paves the way for overiiJlI
employment, i.e., a peculiar situation in which there are more
jobs than the available workers. Money wage rise, profits increase
and interest rates go up. The demand for bank credit increases
and there is all round optimism. At the same time, bottlen~.cks
begin to appear in the economy. Factors of production,
particularly' raw materials and labour becon~e scarce,
commanding higher prices and wages and thereby distort the
cost calculations of the entrepreneurs. They now realise that they
have overstepped the mark and become overcautious. Their over-
optimism paves way for their pessimism. Generally, the failure
·01' a firm or bank bursts boom and lead to recession.
Recession: The entrepreneurs realise their mistakes and find that
many of tht: ventures started in the rosy anticipation of the boom
are not profitable. The over oplimism of the boom gives way to
pessimism characterised by feelings of hesitation, doubt and fear.
Fresh enterprises are postponed for some remote future date and
those in hand are abandoned. Credit is suddenly curtailed sharply
as the banks are afraid of failure. Business l:xrnnsion stars.
order~; :1re cancelled and workers are laid off. Liquidity
preference suddenly rises and people pref~r to hoard rather thail
invest Building activity slows down and unemployment appears in
construction· industries. Unemployment spreads to other sectors
also because the multiplier effect begins to work in the downward
direction. Uncmployment leads to fall in income, expenditure,
prices, profits and industrial and trade activities. Panic prevai l~"
in the stock market and the prices of shares fall rapidly., Once
business and economic activity start declining, it becomes almost
difficult to stop this decline and finally ,ends in a hopeless
depression.
We have described the various phases of a trade cycle, but we
should note, that all these phases rarely display smoothness and
regularity. The movement at times may be irregular in such a
manner that one phase may not easily follow the other. Nor is the
length of each phase by any means always defined. Thus it is quite
likely that a state of fairly stable business depression may lead to
recovery or it may decline to further recession, as was tlie case
with England in 1929. Similarly, a recovery may turn into a
recession without allo''/ing for either full employment or even
boom, as witnessed in the United States in J 937. Sometimes, the
depression may be unstable and recover very rapid. So, alsc at
times prosperity phase may be fairly stable as was the case during
the period between 1924 and 1929.
Some of the important features of various phases 'of a trade
cycle should be 0 emphasised here. They are important when we
have to evaluate the worth of different trade cycle theories.
The process of revival is generally very gradual but once it
picks up,
it becomes rapid.
The boom period of the trade' cycle is marked by high level of
business activity.
The crash of the boom is always sudden and sharp.
The downward trend of the trade cycle is rather very' rapid.
The depression period is prolonged and is painful because of
widespread unemployment.
Trade Cycle Theories
The complex phenomenon of a trade cycle has received the
gr,eatest attention from economist and there arc number of
theories Oil trade cyclc. The following theories on trade cycle are
as follows:
Monctary llnd Non-monctary Thcorics: Trade cycle theories
can he classified into monetary lInd nOIHllOnctnry theories. The
forll\el' llll\phasbl's monetary factors as thc main cause for, while
the Ialler elllphnsis 1l1l!1IlIllm'lllr)' Ihe!ll),:-I, :-Illl'lI ll:ll'lilllillll'
l'lllltllllll'IIS. psyl'll\\hlgy \II' hIlSIIll'~~llh'll and innovations as, thc
main cause for the recurrence or econOllllC fluctuations.
Climatic Theory: The climatic theory is one of the oldest
theories of
tradc cycle. The climatic theory, also known as the sunspot
theory because the spots that appear, on the face of the sun
largely influence climatic conditions. A bad climate causes the
failure of harvests, which in turn lead:i to depression in
business conditions because of a fall in the incomc of" farmers
and consequent fall in their demand for the products of
industries, A good climate, on the contrary, has quite the
opposite effect on trade and industry. The variations of
climate are said to be so regular that periods of good harvest
are followed by periods of bad Ones and consequently booms
and slumps follow each other just as the days and nights, This
theory has been discarded in modern times. While it is difficult
to deny the fact that the prospects of agriculture affect the
pwspects of industries, it is not easy to correlate such a
complex phenomenon of trade cycle exclusively with the
climatic conditions. If the theory has to be correct, then it
should accept th"t trade cycles are less important in non-
agricultural areas and when a nation becomes more
completely industrialised, trade cycles would disappear or at
least diminish in importance. This, however, is not the case; in
fact, it is advanced countries, which seem to suffer most from
the trade cycles.
Psychological Theory: Pigou attempted to explain the trade
cycle with reference to the feeling of optimism and pessimism
among businessmen and bankers. Businessmen have their
moods. Sometimes they feel depressed and at· other times,
they are jubilant and optimistic. Despair, hopelessness as well
as optimism are catching in nature. When 0ne businessman is
pessimistic, he passes it on to the others, similarly,. optimism
spreads 'from OIlC to another. Thus. lIccording 10 the
psychological thcory. industrial l1uctuations are thc outCOIllC
of" the waves or oplilllisl)/ among businessmen. Optimism
results in prosperity and - pessimism in recession and
depression. There is an element of truth in the psychological
theory in the sense that psychological waves of optimism and
pessimism do play an imp()rtant role ill trade cycles. But
busincss con !1dcncc or abSCIll"C of it is often the result
rather than the cause-ofbusiness conditions. Further, the
theory does /lot explain satisfactorily how depression starts or
a recovery begins.
Over-Investment Theory of Von Hayek and Others: Prof.Von
Hayek in his books "Monetary Theory and the Trade Cycle"
and "Prices and Production", has developed theory of business
cycles in terms of monetary over-investment and consequent
over-production. According to him. there is a "natural" or
equilibrium rate of interest at which the demand for loanable
funds is equal to the supply of funds through voluntary saving.
At the same time, there is also market rate of interest based
on demand for and supply of loanable funds in the market.
According to Hayek's thesis as long as the market rate of
interest is same as the natural rate of interest. there will hc
stahility ill husillcss cOlldiliolls alld allY dispilrity bctwcen the
two will lead to busincss Iluctuations. For instance, a fall in the
market rate of interest below the natural rate wililcad to more
investment and, therclore, an upward swing in business
activity. On the other hand, a rise in the market rate of
interest over the natural rate of interest will lead to a fall in
investment and, therefore, a downward swing in business
activity.
Now, the market rate of interest may fall below the natural rate
of interest because money supply increase in excess of demand for
the same. The banks lending to entrepreneurs; through whom it
eventually reaches the consumers bring about this increase in
supply of money. The increased money supply is made available to
the entrepreneurs by lowering the market rate of interest. There is a
spurt of investment activity. More capital intensive methods of
production are adopted. The demand for capital goods naturally
increases and accordingly their prices go up. As a direct
consequence of this rise in the prices of capital goods there is a
diversion of resources from the production of consumption goods to
the production of capital goods resulting in the reduction of the
supply of consumer goods. But this situation cannot continue for
long, for increase in the production of capital goods and higher
prices for them will result in larger income for the factor owners
who, in turn, can normally be expected to increase their
consumption of goods. The demand for consumption goods will also
rise and their prices too will go up. There will now be a competition
between capital goods industries and consumption goods industries
for scarce resources. Naturally, the prices ofJactor series will go up,
raising the cost of production of capital goods industries. The profit
margins of capital goods industries will, therefore, become
unattractivc. At the same time the banking system decides to
reduce the rate of credit expansion by mising the market rate of
interest above the equilibrium rate, causing illvt'~;tment to (all
abruptly. Thus, on the one hand, investment is unattractive because
of lower yield, and on the other, investment is made more
expensive because of higher rate of interest. The business
expansion and boom brought about by IbW market rate of interest
and heavy investment activity crashes when the banking system
puts a stop to additiorlal lending to firms by raising the rate of
interest. Investment and production will decline and depression will
rise.
Hayek(basic thesis can now be summarised as follows.
Alternating stages of prosperity and depression are due to
lengthening and shortening processes of production brought about
by a change in the money supply, which causes a change in the
market rate of interest away from the natural rate of interest. The
lengthening of the process of production is brought about by
increase in moncy supply, which causes the market rate of interest
to fall below the natural rate of interest. Shortening of the process
of production is brought about by a Lleel ine in the supply of bank
money, which raises the market rate of interest above the natural
rate of interest. Therefore, the failure of the banking system to keep
the supply of money constant is responsible for business cycles.
Therefore, to control cyclical fluctuations, Hayek's solution is simple,
i.e., to keep constant supply of bank money, making allowance for
such increases or decreases in the velocity of circulation of money.
Weaknesses of Hayek's Approach
According to Von Hayek, a low rate of interest and large bank
lending to entrepreneurs result into expansion of investment and
production whereas a high rate of interest puts a stop to this
expansion and brings about a depression. Hayek's theory is,
therefore, referred to as monetary over-investment theory of
business cycles. The basic weakness of Hayek's approach is its
emphasis on the rate of interest and complete neglect of real
factors such as technological changes and innovations inC'Juencing
the volume of investment. Further, according to Hayek, the sole
cause for change in the volume of investment is the change in the
market rate of interest relative to the equilibrium rate of interest. A
lower market rate of interest in relation to equilibrium rate of
interest induces entrepreneurs to adopt more :capital-
intensivep;1ethods of production, i.e., to change the capital-output
ratio. Hayek~;however, does not mention how investment is related
to consumer demand. Further more, the importance given to the
rate of interest by Hayek as the cause of change in the volume of
investment is also questioned. Keynes has shown that the rate of
interest is not an important factor for determining the' volume of
investment.
Finally, critics do not accept Hayek's rcmedy. to the problem of
business cyclcs. Hayck suggests that the volume of money supply
should be kept neutral, so that business fluctuations may be
controlled. I r moncy supply is nol nClllml, investment will be either
encouraged (expansion of money) or cliscouraged (contraction of
money supply) and as a result there will be business fluctuations.
This is based on the old quantity theory of money, which does not
command general accepta'1ce .. Moreover, a change in the volume
of investment is not responsible for busines's fluctuations whereas
investment financed by involuntary savings or expansion of bank
credit is to be blamed for fluctuation.
Non-monetary Over-investment Theory
Some economists like Arthur Spiethofr and D.H. Robertson have
also subscribed to the over-investment theory but in a modified
form. Their approach is based on the assumption that Say's law of
markets, which oenies the possibility of overproduction, is valid in a
barter economy but not valid to a money economy in which
transactions are not direct but indirect through money.
Spiethoff believes that over-investment is a basic cause of
business slump but this is not due to low rate of interest or to
expansion of money supply, as Von Hayek has asserted. According
to Spiethoff, over-investment and over-production in one sector may
be passed on to others. For instance, during a business depression
there is excess capacity of durable capital goods. There will be no
investment in these or other related industries. When business
recovery starts, capital goods industries start expanding, and with
that other industries that serve capital goods industries also
expand. For example, expansion of iron and steel industry will lead
to expansion of coal, mining, manganese and transportation. When
these industries expand, income will increase and consequently
demand for consumption goqds will also increase. The upswing
continues till the investment in all industries has reached the
optimum point and in certain lines of production, there is even over-
investment. This leads to the crash of boom conditions.
D.H. Robertson believes that over-investment in some industries
is the result of indivisibilities and this imbalance is worsened by the
banking system, which brings in more money. In his opinion, the
course of economic progress is not generally smooth and as a
malleI' of (act, some degree of fluctuations may be necessary. The
real problem, however, is that the desirable fluctuations may create
excessive responses creating unstable conditions in the economy.
Robertson believes that part of this excessive response is due to
existence of indivisibility in certain investments. He cites the
example of a railway company that faced the problem of congestion
on a single tmck, wanted to go 1'01' a double track. I'll,' introduction
of,i second track would create excess capacity but the additlull:l1

Sl'l'(lIHI ll'lll.'k. II\\'l'Slllll'l\IS h"il\~ lumpy in many hcavy capital-
intensive industries result in exceSs capacity. Besides such
investmcnts arc time-consuming because they have long gcst<ltiull
periods, i.e., time gap between the decision to undertake the project
and the time project is commissioned. Two problems are created as
a result of such investment. Firstly, undertaking heavy investment
in excessive of current demand would lead to blockage of capital
and undertaking smaller investment that would be insufficient to
meet the current demand. Secondly, in a competitive system, many
entrepreneurs may go in for investments with long gestation
periods' that rt:sult into over-investment, over-production and glut
of goods in the market.
While over-investment and over-production ale results of
indivisibilities. they are encouraged by monetary factors. For
instance, the banking system may plJCC additional volume of
money at the disposal of entrepreneurs and thus increase the
already existing state of imbalance. Increase in money supply will
cause prices to rise, thereby misleading their appraisal of
prospective profits. This price rise encourages entrepreneurs to
further over-investment. Thus, D.H. Robertson successfully
combines real and monetary factors to explain business cycks.
Overinvestment theory has definite merit in the sense that the
business boom is identified by too much investment in general or
particular industries. TIllS IS largely true. However, the real
weakness of the theory is its failure to exp~ain revival from a
business depr~ssion.
Over-Saving or Under-Consumption Theory
This is one of the earliest theories of trade cycle and has been
stated in different forms at different times. Such "Yell-known names
as Malthus, Marx and Hobson are associated with this theory.
According to this theory, in free capitalist society rich people have
large incomes but they are unable to spend all their incomes and
hence they save automatically. These savings are usually invested
in industry and hence they increase the volume of goods produced.
At the same time, the majority of people in the country have low
incomes and consequently have low propensity to consume. Thus,
consumption is not increasing correspondingly to production. As a
result, the market is flooded with goods and will be followed
bY,depression unless prices fall to a very low level in order to allow
the goods to be carried oll the market. The fundamental idea of the
under-consumption theory is based upon the conflict, which arises
from the double effect, that saving has on consumption and
production. It is the decrease in the demand lor and the increase in
t.he supply of consumer goods as a res 'jlt of saving which seems to
create under-consumption and over-production.
Like all other theories of trade cycles, this theory too is not free
from defects. It does not explain complete trade cycle. It is pointed
out that the theory concentrates too much on over-saving and its
related evils and too little on the others. It considers savings
automatically linding their way into investments while in reality this
is not so. The availability of savings does not guide entrepreneurs in
t!lt.:ir investment policies. Thus, a mere increase in savings is
insufficient to explain occurrence of a boom.
Hawtroy's Monetary Theory
Hawtrey regards trade cycle as a purely monetary phenomenon.
According to him, non-monetary factors like wars, earthquakes,
strikes and crop failures may cause partial and temporary
depression in particular sectors of an economy. However, these
non-monetary factors cannot cause full and permanent depression
involving general unemployment of the factors of production in a
trade cycle. On the other hand, changes in the flow of money are
the exclusive and sufficient cause of changes in trade cycle. In
Hawtrey's opinion, the basic cause of trade cycle is the expansion
and contraction of money in a country. According to Hawtrey,
changes in the volume of money are brought about by changes in
the rate of interest. For instance, if banks reduce their rate of
interest, producers and traders will be induced to borrow more from
banks so as to expand their business. Borrowing from banks will
lead to more bank money and rise in the price level and business
activity. On the other hand, if banks raise their rate of interest,
producers and traders will reduce their borrowing from banks. This
will reduce the price level and business activity. Thus, in Hawtrey's
analysis, changes in interest rates lead to changes in borrowing
from banks and, therefore, changes in the supply of money.
Changes in the supply of money lead to changes in 'Jusiness
activity.
Trade Cycle in Just Inflation and Deflation
f-Iawtrey argues that the trade cycle is nothing but small-scale
replica of an outright money inflation and deflation. The upward
phase of a trade cycle, such as revival, prosperity and boom is
brought about by an expansion of money and bank credit and also
by increase in circulation of money supply. On the other hand, the
downward swing of money supply is nothing but a monetary
denatibn.
Expansion of bank loans is made possibk by fall in rute of
interest, which induces the merchants to' increase their stocks since
banks grants loan more liberally. Therefore, merchants begin to
place more orders and increase production by employing more
resources. There is greater demand for factors of production all
round and consequently higher income and employment leading to
further increased demand of goods. In course of time, a cumulative
upward trend is set in motion. As the volume of business expands
and factors of production arc rendered fully employed, prices rise
further and further induce upward business expansion. resulting in
inflationary conditions or boom conditions. However, the boom
crashes when the ba'lking authorities suspend their policy of credit
expansion.
Why the Boom Crashes Suddenly?
The banks suspend credit and call on the borrowers to return the
loans, ci'ther because banks have reached the maximum point
beyond which they cannot givc any more loans or they are afraid
that the phase of business expansion has reached a saturation point
and hence a downward trend may set in the immediate future. Now
the sudden suspension of credit facilities by the banks comes as a
shock to entrepreneurs and merchants. Until now entrepreneurs and
merchants were enjoying liberal policy of the banks and now,
contrary to their expectations, they receive sudden notices of
immediate call-back of loans to dispose of their stocks at any price
in order to repay bank loans. This general desire of businessmen to
dispose of their stocks will definitely depress the market and bring
down the prices. With every fall in prices, the desire to dispose of
the stocks as quickly as possible wi!! lead to confusion and collapse
of the market. Marginal and average fimls may even go into liq-
uidation, thus worsening the position still further and making the
banks extremely nervous. Banks will proceed to further contraction
and like the period of expansion, it will become cumulative.
Producers curtail output and consumers' income and outlays
decrease and contraction spirals in a downward direction, until it
touches the lowest level possible.
How the revival takes place?
When the economy is working at the level of depression, the rate of
interest is low and the bank,....: have large cash reserves. On one
hand, low interest rates make it profitable to 'borrow and invest. On
the other hand, large cash reserves induce banks to lend. This starts
the phase of revival, which because of its cumulative character,
leads to prosperity and boom conditions. This, according to Hawtrey,
the inherently unstable nature of the modem monetary and credit
system is the mother or economic fluctuations. This monetary
explanation of the trade cycle has received powerful support from
Milton Freidman, who says, "In every deep depression, monetary
factors playa criticai role~" According to Freidman, there is a direct
relation between the volume of money supply and the level or
business activity in a country. If the money supply increases at a
rate faster than the economy's real output of goods and services,
prices will decline and the economy is bound to contract. Thus,
there is direct relation between the level of income and economic
activity, on the one side and the volume of money supply on the
other. If the 'economy has to be stable, monetary expansi9n and
contraction has to be avoided.
Weaknesses of the Monetary Expansion
The weakness of monetary expansion is as follows:
Finance is the soul of commerce and trade in modern times
and the banking system plays quite an important part in
financing trade activities. However, it is correct to say that
banks cause business crises.
Hawtrey's theory would have been all right in those days
when the gold standard was universal and when the volume of
money supply was fixed to gold reserves. Currency and credit
could expand only when gold reserves increases. These days,
gold standard does not exist clnd, therefore, Hawtrey's theory
is really weak.
Borrowing and investment will not depend upon the rate of
interest, as Hawtrey believes. A high rate of interest will not
deter people· from borrowing for investment, and a low rate of
interest will always induce people to borrow and invest.
Expansion and contraction of money alone cannot explain
prosperity and depression.
According to Hawtrey, expansion and boon'! are the result of
expansion of bank credit, but it is pointed out that the mere
expansion of bank credit by itself cannot initiate a boom.
Further, according to Hawtrey, a depression is marked by
contraction of bank loans and advances but actually, the
contraction of bank credit is the ·result of depression. .
Lowering of interest rate and willingness of banks to - give
loans and advances cannot be a -sufficient reason to stimulate
the economy to revive. Businessmen will not borrow and invest
unless they are convinced that the economy will definitcly
I"cvivc 1I11d il will he prnntllbk to bOl'rnw Hnt! invest.
In recenl years, lhe technique \It' tinlllll:ing has been changing
illlLl practically all finns, both big and small, havc becn
resorting to the policy or ploughing back of profits. The
conclusion, which follows, is that the banking system can
accentuate a boom or a depression but it cannot originate one.
In other words, expansion and contraction of bank credit can
be a supplementary cause but not the main cause of trade
cycles.
Keynes' Theory of Trade Cycles
Keynes never worked out a pure theory of trade cycles, though he
made significant contributions to the trade cycle theory. Keynes
states, "The trade cycle can be described and ana lysed in terms of
the fluctuations of the marginal efficiency of capital relatively to the
rate of interest." According to Keynes, the level of income and
employment in a capitalist economy depends upon effective
demand, comprising of total consumption and investment
expenditure. Changes in total expenditure will imply changes in
effective demand and will lead to changes fn income and
employment in the country. Therefore, in the Keynesian system
fluctuations in total expt(nditure are responsible for fluctuations in
business activity. Now, according to Keynes, consumption
expenditure is relatively stable, and consequently it is the
fluctuations in the volume of investment that are responsible for
changes in the level of employment, income and output.
Investment depends up0l) two factors: (a) marginal efficiency of
capital, and (b) the rate of interest. Investment is carried on up to
the point where the marginal efficiency of capital (the profitability of
capital) is equal to the rate of interest (i.e., the cost of borrowing
capital). Keynes argues that the rate of interest will depend upon
the liquidity preference of the people in the country and the
quantity of money available. In the short period, the rate of interest
will be stable and hence it is not responsible for causing cyclical
fluctuations in trade cycles. According to Keynes the fluctuations in
the marginal efficiency of capital are the fundamental cause of
fluctuation in trade cycles.
The following Figure 6.5 shows how trade cycle depends upon the
marginal efficiency of capital, which according to Keynes, is the
villain of the piece. The substance of Keynes' theory is that an initial
investment outlay will generate multiplc amount of income and
employment under the int1uence of the multiplier and acceleration
effects. On the other hand, 'co;ntraction of investment will similarly
lead to multiple contractions of incom~and employment. But
whether a fresh investment will be Lindertaken will depend upon the
marginal efficiency of capital. We can explain these pOint$ a little
more elaborately.
How Recovery Starts?
Let us start at the bottom of a depression. At this point, the
marginal efficiency of capital will be high due to exhaustion of
accumulated stocks and necessity to replace capital goods. At the
same time, the rate of interest may be low because of large cash
balances with commercial banks or due to fall in the public liquidity
preference. As a result, the entrepreneurs may borrow fu~ds from
banks and make fresh investments. Under the impact of the
multiplier an<i acceleration effects, the process of increased
investment and employment gets an upward trend. There is heavy
economic activity everywhere in the primary, secondary and
tertiary sectors of the economic system. This sudden shoot in
investment activity gives rise to boom and as long as it lasts, the
economic situution appears very easy and bright.
How the Boom Crashes?
The boom conditions thcmselves contain the very seeds;of their
own destruction. Very soon goods are accumulated beyond the
expectations of entrepreneurs and competition among them to
dispose their accumulated stocks bring crash in prices. While the
prices of finished goods are declining, their costs of production
continuously rise because factors of production are bceoming
scarce and hence are commanding hi,!~her prices. The· marginal
efficiency of capital is sandwiched between rising costs of
production-on the one side and falling prices of finished goods :In
the other. The marginal efficiency of capital, therefore, collapses
and brings about a crash in the investment market.
Ineffectiveness of the Rate of Interest
Keynes believes that the rate of interest could have prevented the
collapse of the marginal efficiency of the capital and revives the
confidence among the entrepreneurs, by exerting its pressure to
reduce cost. Uut then, the rate of interest is very high, like all
other prices and wages. The rate of interest goes up due to a rise
in the liquidity preference of the people. The marginal efficiency of
capital falls below the current rate of interest and thus, the decline
of investment is aggravated. Keynes believes that at this stage a
reduction in the rate of interest is neither easy nor adequate to
restore confidence and revive investment. In Keynes' theory of
trade cycles, the margina~ efficiency of capital has great
significance than the rate of interest. In fact, it disturbs the
equilibrium of the economy and thereby causes fluctuations in the
economy. The other factor that occupies an equally important
place in Keynes theory is the "investment multiplier". However, for
the active operation of investment multiplier, the cycle needs to be
milder in magnitude than what it actually is.
Weaknesses of the Keynesian Analysis
Keynes' theory of the trade cycle has been regarded as quite
convincing since it explains cbm:ctly the cumulative processes,
both in the upswing as well as in the downswing. Besides, Keynes'
advocacy of fiscal policy to bring about business stability has been
widely used. However, critics have found some weaknesses in the
Keynesian analysis. First, according to Keynes, marginal efficiency
of capital is the most important factor that guides the investment
decisions of the entreprencurs. However, this important factor
depends on entrepreneurs' anticipation of future prospects that
further depend upon the psychology of investors. If'. such a .case,
Keynes' theory of trade cycles approaches close to Pigou's
psychological theory. Secondly, in Keynes' theory, the rate of
interest plays a minor role. Keynes expresses the opinion that
sizeable fall in the rate of interest can do something to. revive the
confidence among the entrepreneurs by exerting pressure on the
cost of production. However, Keynes himself has pointed out that
this has been sufficiently proved to be correct that the rate of
interest does not have any influence on investment. Thirdly, his
theory does not throw light on the periodicity aspect of the trade
cycle.
Finally, some critics like Hazlitt have pointed out that Keynes'
concept of the rate of interest does not tally with actual market
conditions. For instance, according to Keynes, in a period of
recession and depre~sion, the rate of ir:'erest ought to be high
because of strong liquidity preference but precisely during this
period, the rate of interest is low. Likewise during boom conditions,
the rate of interest ought to be lower because of the weak liquidity
preference among the people instead it is high.
Hicks' Theory of Trade Cycles
In his book "A Contribution to the Theory of the Trade Cycle," Hicks
has developed a theory mainly by combining the principles of the
'multipiier and acceleration, which he has borrowed from Keynes
and has combined the concepts of autonomous and induced
investment, a distinction originally made by Roy Harrod. The
multiplier is related to the autonomous investment of the
Government. The acceleration principle is based on induced
investment.
The above Figure 6.6 shows the influence of the two types of
investment on the level of income and cyclical fluctuations. The
horizontal axis represents the number of years and the vertical axis
represents the level of economic activity. Line AA' represents the
progress of autonomous investment over thc years and it slants
upward at a uniform rate to indicate that autonomous investment
grows over time at a constant rate. Line EE' represents the income
(or output) corresponding to the aUlononious investment line AA·.
EE' IS at a higher level than AI\" because it rerresents the eomhined
innllellce of mllitiplk'r flnd flccelerrllioll effects n.~ n result
or ,lulollOlllllUS illvestl:lellt (AA '), III fact, the distallce bC1WL'Cil A/\'
lIlld EE' will depend upon the combined inlluence of the multiplier
and acceleration effects. Finally, line FF' represents the level of full
employment.
The Process of Cyclical Fluctuation
Suppose the economy is at point P in the Figure 6,6 and at
this .point, a certain invention is introduced. As a result, there is
burst of autonomous investment, which may be short-lived. But the
induced investment will push output and employment upward along
the path marked PP1, away from the EE' line. Th,e upward trend
touches full employment ceiling at PI and cannot ~ise further. At
the most, the expansion can "creep along" the' ceiling but only for a
limited time. When the path has encountered the edling, it must
bounce off from it and begin to move in a downward direction.
According to Hicks, this downward swing is predictable. The
initial burst of autonomous investment is short-lived and after a
stagc, it will fall to the usual level. But the induced investment,
which was the result of the initial autonomous investment and the
initial increase in output, would continue and push ahead on path
PP1• But the induced investment is not sufficient to support a
growth of output along the path FF' but it is sufficient to support an
output which expands along the equilibrium path EE', Output,
therefore, will bounce back from FF' towards EE'.
The downward swing is gradual along the path P2RRI and rapid
along P2RR2. At first, the downward swing may appear. to be
gradual but, in practice, it will be rapid. The reason is that once
the decline in output is initiated, it gathers momentum and tends
to proceed at a fast rdte. Hicks give a monetary explanation to this
phenomenon. As the downward movement starts, it becomes
increasingly di fficult to sell goods and consequently the burden of
fixed cost becomcs oppressive. Therefore, firm after firm becomes
bankrupt and liquidity preference records a sudden and abrupt
rise and reacts most adversely on credit situation. At [he same
time the stringent conditions in the credit market, forces business
activity to fall to the lowest ebb and thereby aggravate the
situation. Thus, Hicks' theory of trade cycles makes use of
multiplier and acceleration principles, which are combined, to the
fluctuations of autonomous and induced investment. It is induced
investment, which is finally rcsponsibleJor the upward push and
downward swing of output and income of prices and employment.
Schumpeter's Innovations Theory
Joseph Schumpeter has propounded a trade cycle theory in terms
of innovations. An innovation can be regarding new product or new
method of production, such as new machinery, new method of
organisation of factors of production, opening of a new market for
the product and development of new source of raw materials. In
other words, an innovation is anything that is introduced by a firm
or an industry to change the supply or demand conditions. An
innovation may be sufficient to cause changes in expectations of
entrepreneurs and their economic and business calculations.
These changes may cause the cost of production to change rapidly
and continuously and may shift the demand curve continuously in
such a manner that the final stage . becomes indeterminate. Any
innovation, thus, causes disequilibrium in the economic system,
making it necessary for the economic system to readjust itself at
some new equilibrium position. Thus, Schumpeter explains the un-
rhythmic movements of an economy by reference to innovations.
The Effect of Innovations
Suppose we start with an economy, which is functioning at full
employment level. Suppose an innovation in the form of a new
product has been introduced. The new industry will need to have
new plant and equipment. Since the economy is already working at
full employment level, the new plant and equipment required by
the new industry can be acquired only by withdrawing labour and
other resources from old industries. As a result of higher cost of
factor of production, the old industries will experience both an
increase in their cost of production as well as j~crease in their
output. The promoters of the new product will have to attract all f(!
ctors of production by offering higher rewarqs and the necessary
finance may ,:i: 'me out of additional bank loans. Since the factors
of production, both in the new ;tl'd the old industries, are getting
higher money remuneration therefore, they will ',~( 'nand more
goods and services and consequently will push up prices, Thus,'ill
'<'::IS<:U ucmanu [or anu the simultaneous decreased supply of
the old goods will ~ It:"h upward the prices of these goods.
However, it is not necessary that the in 'case in the demand alld
costs of all industries should nec~ssarily be equal. The i l_:
industries, whose demand for products rises more rapidly than
production ~ lHS, will reap abnormal profits and consequently will
expand, To the extent the l (1',1 involved in such expansion is
financed by hank credit therefore. the i d1:qi"":1r\' I'I'I":'nll'l' "11
I'rk"'l <111.1 ,'\1';1.'1 i .. : Illt\gllilkd.
The Process of Rising Prices
When the new product introduced in the mark~, becomes
commercially successful and brings in profit for promoters, the rival
competing firms quickly introduce similar products and imitations.
The production of many competing varieties of products sets in
motion expansion in many related industries. Therefore, resulting
into a period of cumulative prosperity.
The Process of Falling Prices
The deflationary effect follows when the novelty of the innovation is
lost with the production of so many competing varieties or brands of
the S3me product. Abnormal profits are competed away. Some of
the firms may even incur losses and close down their businesses,
thus layoff labour and other agents of production. Therrfore, the
demand for goods is reduced. A similar deflationary effect is
experienced whcn the innovating firms return their bank loans out
of their profits and thus reduce the volume of money supply in the
economy. The "vicious circle of deflation" is generated in this
manner.
Criticism
First, Schumpeter's theory is based upon two assumptions
regarding full employments of rf'sources in the economic system
and financing of innovation by means of bank loans. If an economy
is working below full employment, the introduction of an innovation
need not cause diversion of factors of production from older
industries and thus cause prices of goods to go up or their supply to
iecline. Again, innovation is generally financed by the promoter
themselves and hence, resort to bank .finance does not arise at all.
Secondly, innovation.s may be regarded as one cause for business
fluctuations but not the only cause, as there are many other causes
also. As Hayek correctly points out, innovations alone cannot
explain the phenomenon of trade cycles without a substantive
monetary explanation. We have described man;' theories of
business cycles and there are many morc. Therefore, none of the
theories provides a complete explanation of the causes of trade
cycles. The reason for this is that the trade cycle is not the result of
anyone single factor but is due to multiplicity of factors, of which
sometimes one and sometimes another becomes dominant.
Control of Trade Cycles
Thc trade cycle, which implies fluctuations in business activity, is
not beneficial to allY seetioll of a community. The period of
expansion is accompanied by large profits to producers and
speculators but it brings loss to lixcd income groups. The period of
depression is one of acute unemployment, poverty, suffering and
misery to the poor and of distress to the busin(;ss dass(;s as
a .result of exlensive hlltlk lIlId firms failures. Thus all sections of
people in a country, especially the working classes, are interested in
preventing and avoid ing busihess cycles .. On/ of the 1110st
important objectives of economic policy is the elimination of cyclical
fluctuations and attainment of stability at the level of full
employment. This has been, in fact, the main objective of both
monetary and fiscal policies. We have already explained the use of
monetary policy and fiscal policy as wel'l as direct control, to check
inflations and deflations.
There is no full proof method for solving the problem of trade
cycles.
Karl Marx considered trade cycles as inevitable in a capitalist
system and the only rational method to solve the problem was to
throw it overboard and introduce a socialist economy. Like every
business firm prepares its annual balance sheet of transactions with
a view to know its assets and liabilities, every nation carrying out
economic transactions with foreign countries prepares its Balance of
Payment (BOP) Accounts periodically with a view to know stock of
its assets and liabilities and its receipts from and payments to the
rest of the world.
THE BALANCE OF PAYMENT
Definition
The balance of paYlllent is defined as a systematic record of all
economic transactions between the residents of a country and
reside~ts of foreign countries during a certain period of time.
Although the above definition of balance of payments is quite
revealing certain terms used in the definition may require some
clarification. The term's systematic record does not refer to any
particular system. However, the system generally adopted is double
entry book-keeping system. Economic transactions include all such
transactions that involve the transfer of title or ownership. While
some transactions involve physical transfer of goods, services,
assets and money along with the transfer of tille while other
transactions do not involve transfer of title. For example, suppose
that a subsidiary company of a foreign undertaking is operating in
India and 'making profit. This company may pay all its profits as

Purpose
The balance of payment serves a very useful purpose as it yields
necessary information for the future policy formulation in regard to
domestic monetary and fiscal pulicies and foreign trade policy.
Following are the important uses of balance of payments:
It provides useful data for the economic analysis of country's
weakness and strength as a partner in the international trade.
By comparing the statements contained in the balance of
payments for several successive years, one can find out
whether international economic position of the country is
improving or deteriorating. In case it is deteriorating,
necessary corrective measures can be taken.
It reveals the changes in the composition and magnitude of
foreign trade. The changes that curb ~conomic well-being of
a country are taken care by the government.
It also pwvides indications of future repercussions based on
countries past trade performances. I f balance of payments
shows continuous and large deficits over time then it
indicates growing international indebtedness, which
ultimately leads to financial bankruptcy. Similarly. a
continuous large-scalc surplus in the balance of payments,
particularly wht:n its magnitude goes beyond the absorption
capacity of the country indicates impending dangers of
inflation.
Detailed balance of payments accounts also reveal weak and
strong points in the country's foreign trade rdationsund
thereby invite gove.-I1ll1cnt attention to the need for
corrective measures against the weak spots.
Balance of Payments Accounts
The economic transactions between a country and the rest oCthe
world may be grouped under two broad categories:
1. Current transactions: Current transactions pertain to export
and import of goods and services that change the current
level of consumption in the country or bring a change in the
current level of national income.
2. Capital transactions: Capital transactions arc those
transactions, which increase or decrease counlry's Iota I stock
of capital, instead of affecting the current level of
consumption or national income. In other words, current
transactions arc flow transactions. In accordance with the two
kinds of transactions, balance of payments account is divided
into two major accounts:
A. Current account
B. Capital accounts
Current Account
The items, which are entered in the current account of balance of
payments, are listed in the Table. 6.4 -in the order of their
importance. The categories of items presented in the table were
published by the IMf and are currently followed in India. In the
'credit' column values receivable are entered and in 'debt' column
values payable ar.e entered. The net balance shows the excess of
credit over the debit for each item, can be negative (-) or positive
(+). The items listed in current account can be further grouped into
visible and invisible items. Merchandise trade, i.e:, export and
imports of goods, fall under the visible items. Rest all other items in
the current account-payment and receipt for the services, such as
banking, insurance and shipping are termed as invisible. Sometimes
another category, i.e., un-required transfer, is created to give a
separate treatment to the items like gifts, donations, military aid,
and technical assistance. These are different from other invisible
items since they involve unilateral transfers.
The net balance on the visible items, i.e., the excess of
merchandise exports (Xg) over the merchandise imports (Mg) is
called as balance of trade. If Xg < Mg it is unfavourable. The overall
balance on the Current Account is known as 'Balance on Current
Account.' The 'Balance on the Current Account' either surplus or
deficit is carried over to the Capital Account.

Capital Account
As mentioned earlier, the items entered in the capital account of
balance of payments are those items, which affect the existing stock
of capital of the country. The broad categories of capital account
items are: (a) short-term capital movements; (b) long-term capital
movements; and (c) changes in the gold and exchange reserves.
Short-term capital movements include (i) purchase of shortterm
securities such as treasury. bills, commercial bills and acceptance
bills, etc.; (ii) speculative purchase of foreign currency; and (iii) cash
balances held by foreigners for suchfeasons as fear of war and
political instability. An item of short-term capital results often from
the net balances (positive or negative) in the Cljrrent Account. Long-
term capital movements include: (i) direct investment in shares,
bonds, real estate and physical assets such as plant, building and
equipments, in which investors hold a controlling power; (ii) portfolio
investments including all other stocks and bonds such as
government securities, securities of firms which do not entitle the
holder with a controlling power; and (iii) amortisation of capital, i.e.,
repurchase and resale of securities carlier sold to or purchased from
the foreigners. Direct export or import of capital goods fall under the
category of direct investment. It should be noted that export of
capital is a debit item whereas export of merchandise is a credit
item. Export of goods result in inflow of foreign currency, which is an
addition to the circular flow of money income, whereas export of
capital results in outflow of foreign exchange which, amounts to
withdrawal from the foreign exchange reserves. Geld and foreign
exchange reserves make the third major category of items in the
capital account. Gofd and foreign exchange reserves are maintained
to stabilise the exchange rate of the home currency and to make
payments to the creditors in case there exists payment deficits on
all other accounts.
Balance of Payments is always in Balances
The balance of payments accounting is based on the double-entry
book-keeping system in which both sides of a transaction, i.e.,
receipts and payments are recorded. For example, exports involve
outtlow of goods and inflow of foreign currency. Similarly, imports in
volve inflo\\ of goods and outflow of foreign currency. Both, inflow
and outflow are recorded in this system. International borrowing
and lending give rise to credit to the lender and debit to the
borrower. Both are recorded in the balance of paymcnts. However,
donations, gifts, aids and assistance are unilateral transfers and do
not involve transfer of an equivalent value. In regard to these items,
there is only credit and no debit since they are nonrefundable. Yet,
the receiving country is debited to keep the record of nonrefundable
amounts and donator is credited for the record purposes. Such
entries have information value for non-economic purposes. Besides,
these transactions reduce the deficit in the current account of the
reporting country. Since in this system of balance of payments
accounting international transactions are entered on both debit and
credit sides. Balance of payments always balances from the
accounting point of view.
Disequilibrium in Balance of Payments
We have noted above that the balance-of payments is always in
balances from accounting point of view. Besides, in the accounting
procedure, a deficit in the current account is offset by a surplus in
capital account resulting from either borrowing from abroad or
running down the gold and foreign exchange reserves.
Similarly, a surplus in the current account is 011set by 1I
mlltdling Jl'licit in capital account resulting from loans llnd gills to
debtor country or by dcpklion (),' its gold and foreign exchange
reserves. In this sense also. lhe '11,lIallce (!I JlllYIJl!:lltS' 1IlwlI)'s

disequilibrium in the balance of payments. However,
disequilibrium in lhe balall!:l: of payments does arise because
total receipts during the reference pl:riod need 1I0t be necessarily
equal to the total payments. When total receipts do not m<lleh
with total payment of the accounting period, this is a position of
disequilibrium in the balance of payments. The final balance of
payments position is obtained in the manner described below.
For assessing the over-all balance of payments position, the total
receipt and total payments arising out of transfer of goods and
services and long-run capital ' movements are taken into account.
All the transactions are regrouped into autonomous and induced
transactions. Autonomous transactions take place on their own all
account of people's desire to consumc morl: or to makc a larger
profit. For example, export and imports of items in current account
are undcrtaken with a view to, make profit or consume more goods.
Another autonomous item in the current account is gift or
donations. They are voluntary and deliberate. In the capital account,
export and import of long-term capital are autonomous
transactions. In addition, the short-term capital movements
motivated by the desire
to invest abroad for higher return fall in the category of autonomous
transactions. Thus. all exports and imports of goods and services,
long-term and short-term capital movements motivated by the
desire to earn higher returns abroad or to give
gi fts and donation are the autonomous transactions. Exports and
imports take place irrespective of other trans~ctions included in the
balance of payments accounts. !-!ence, these are autonomous
transactions. If exports (Xg) equal imports (Mg) in value, there will
be no other transaction. However, if Xg is less than Mg, it leads
to short-run capital movements, e.g., international borrowing or
lending. Such international borrowings or lending are not undertaken
for their own sake, but for making payment for the deficit in the
balance of trade. Hence, these are called induced transactions. They
involve accommodating capital flows.
On the other hand, the short-term capital movemcnt's viz., gold
movemenls it and accommodating capital movements on accounts
of thc autonomous transactions are induced transactions. These
transactions lead to reduction in the <, gold and foreign exchange
reserves of the country.
In the assessment of balance of payments position only autonomous
transactions are taken into account. The total receipt and payments
resulting from the autonomous transaction determine the deficit or
surplus in the balance of payments. I f total receipts and payments
arc unequal, the balance of payments is in disequilibrium. I I' the
total payments exceed the lotal receipts, the balance or payment
shows deficit. On the contrary, if receipts from autonomous
transactions exceed the payments for autonomous transactions, the
balance of payments is in surplus. Naturally, if both are equal, there
is neither deficit nor surplus, and the balance of payments is i~1
equilibrium. From the policy point of view, the depletion in the gold
and foreign exchange reserves is generally taken as an indicator of
balance of payments running into deficit, which is a matter of
concern for the government. However, if reserves are plentiful and
the government has adopted a deliberate policy to run it down, then
the deficit in the balance of payments is not an in he?lthy sign for
the economy. Besides, the disequilibrium of surplus nature except
the one that might cause inf1ation is not a serious matter as the
disequilibrium of deficit nature. We will be therefore, concerned
here mainly with the deficit kind of disequilibrium in the balance of
payments.
Causes and Kinds of BOP Disequilibrium
The deficit kind of disequilibrium in the balance of payments arises
when a country's autonomous payments exceed its autonomous
receipts. The autonomous payments arise out of imports of goods
and services and export of capital. Similarly, autonomous receipts
result from the merchandise exports and import of capital. It may
therefore be said that disequilibrium of deficit nature arises when
total imports exceed total exports. However, imports and exports do
not determine themselves. The volume and value of imports and
exports are determined by a host of other factors. As regards the
determinants of imports, the total import of country depends upon
three factor: (i) internal demand for foreign goods, which largely
depends on the total purchasing power of the residents of the
importing country, (ii) the prices of imports and their domestic
substitutes, and (iii) people's preference for foreign goods. Similarly,
the total export of a country depends on (i) foreign demand for its
goods and services, (ii) competitiveness of its price and quality, and
(iii) exportable surplus.
Under static conditions, these factors remain constant.
Therefore, equilibrium in the balance of payments, once achieved,
remains stable. However, under dynamic conditions, factors that
determine imports and exports keep changing, sometimes gradually
but often violently and unexpectedly. The changes differ in their
duration and intensity from country to country and from time to
time. The changes, which occur as a result of disturbances ,in the
domestic economy and abroad, create conditions for dis-equilibrium
in the balance of payment.
Causes of Disequilibrium and the Associated Nature of
Imbalances
Price Changes and Disequilibrium: The first and the major
cause of disequilibrium in the balance of payment is the
change in the price level. Price changes may be inflationary or
deflationary. Deflation normally causes surplus in the balance
of payment. The balance of payments surplus does no! cause
a serious concern from the country's point of view. It may,
however lead to wasteful expenditure and mal-allocation of
resources. On he C1ther hand, inflrtionary changes in prices
causes deficits in the balance of payments. The balance of
payments deficit result in increased indebtedness, depletion
of gold reserves. loss of employment. and disfort:ons in the
domestic economy and causes other economic problems in
the deficit countries. Therefore, we will discuss only the
impact of inflationary price changes on the balance of
payments position.
Inflation causes a change in the relative prices of imports and
exports. While exchange rate remains same, inflation causes
increase in imports because domestic prices become
relatively higher than the impo;L prices. On the other hand,
inflation leads to decrease in exports because of decrease in
foreign demand due to increase in domestic prices. The
increase in imports depends also 011 price-elasticity of
demand for imports in the home market and decrease in the
exports depends on the price-elasticity of foreign demand for
home-products. In case price-elasticity of imports and exports
is not equal to zero, imports are bound to exceed the exports.
As a result, there will be a deficit in the balance of payments.
If inflationary conditions perpetuate, it will produce long-run
disequilibrium. If the size of deficit is large and disequilibrium
is inflexible, it is termed as a fundamental disequjJibrium. The
price changes or fluctuations may be local, confined to one or
few countries or it may be global as it happened in the ec:(/y
1930s. If price fluctuations take the form of business cycle,
most countries face depression and inflation almost
simultaneously. Since economic size of the nations differs,
their imports are affected in varying degrees. Deficits and
surpluses in the balance of payment vary from moderate to
large. The countries with higher marginal propensity to import
accumulate larger deficits during inflationary phase of trade
cycle and a moderate deficit or even surplus, during
depression. Such disequilibrium is known as;;' cyclical
disequilibrium. This is however only a theoretical possibility.
Since little is known about the marginal propensities to
import, any generalisation would be unwise.
Structural Changes and Dis-equilihriull1: Structural changes, in
an
economy arc caused by factors, such liS, (i) depletion orthe
cheap natural resources (ii) change in technology with which
a country is 110t in a position to keep pace, i.e., technology
lag and, (iii) change ill consulllers' !lIsle IInd preference. Such
changes incapacitate exporting countries and they lind it
difficult ,10 face competition in the intnnational market, due
toeither high cost of production or lack of foreign demand. To
quote the examples from P.T. ,Ellsworth the gradual
exhaustion of better coal in Great Britain resulted' in
increased cost of coal production despi!e improvement in
technology. This factor combined with labour problem
converted Great Britain from a net coal-exporting nation to a
net-importing one.
All such changes bring change in demand and supply
conditions. If size of foreign trade is fairly large, then the
balance of payments is adversely affected. The ultimate result
is disequilibrium in the balance of paym~nts. It is called
structural disequilibrium. The structural disequilibrium may
also originate from thc discovery of new resources, which may
invite foreign capital in a large measure. The large-scale
capital inflow may turn th~ balance of payments deficit into a
surplus.
Other Factors: In addition to the fundamental factors
responsible for disequilibrium in the balance of payments,
there are certain other factors, which may cause temporal
disequilibrium, Some of them are as follows:
Disturbances or crop failure particularly in the countries,
producing primary goods, for examplc, India.
Rapid growth in population leading to large-scale imports
of food materials.
Ambitious developmen! projects requiring heavy imports
of technology, equipmenCs,machinery and technical know-
how.
Demonstration-effect of advanced countries on the
consumption patternof less developed countries.
Balance of Payments Adjustments
The short-term and small deficits in the balance of payments are
quite likely to cmcrge in wide range of international transactions.
These cleficits do not call for immediate corrective actions. More
importantly, irregular short-term changes in the domestic economic
policies with a view toremove the short-term deficit in the balance
of payments may do morc harms than good to the economy. Since
these changes cause dislocations in the process of reallocation of
resour'ces and short- Icrm lluctUlItiolls in the cconomy, Therefore,

and political independence of these countries. India faced a similar
situation in July 1990. Therefore, a country facing constant large
deficits in ih balance of payments is forced to adopt corrective
measures, such as changes in its internal economic policies for
wiping out the deficits, or at leasl to bring it l(l •• manageable size.
It is a widely accepted view that the conditions for an automatic
corrcctive mcchanism visualised under gold standard, bascd on
international pricemechanism do not exist. Therefore, the
government has no option but to intervene . ~ with the market
conditions of demand and supply with the policy measures available
(0 them. It should be borne in mind that policy-mix in this regard
may vary from country to country and from time to time depending
on the prevailing economic conditions.
Measures used to Correct Deficits in Balance of Payments
The various measures used to correct deficits in balance of
payments are as follows:
Indirect measures to correct adverse BOP: Under free trade
system, the deficits in the balance of payments arise either
due to greater aggregate domestic demand for goods and
services than the total domestic supply of goods and services
or domestic prices are significantly higher than the foreign
prices. Thus, the deficit may be removed either by increasing
domestic production at an internationally comparable cost of
production or by reducing excess demand orby using the two
methods simultaneously. It may be very difficult to increase
the output in the short-run, specially when a country is close to
full-employment or when there ~re other limiting factors to its
industrial growth. Thcrcforl.:, thl.: only way to rcducl.: ddicil is I
to reduce the demand for foreign goods.
Income and Expenditure Policies: Here we discuss how
reduction in . income can lead to reduction in demand and
how it helps reducing the deficit in the balance of payments.
The t'.vo policy tools to change disposable income are
monetary llnd fiscal policies. Monetary policy operates on the
demand for and supply of money while fiscal policy operates
on the disppsable income of the people. The working and
efficacy on these policies as i,nstruments of solving balance of
payment problem is described below.
Monetary Policy
The instruments of mon~tary policy include discount 01" bank rate
policy, open market operations, statutory reserve ratios and
selective credit controls. Of these, first two instruments are adopted
in the context of balance of payment policy. This however should
not mean that other instruments are not relevant. The government
is free to choose any or all of these instruments amI adopt them
simultttneously.
To solve the problem of deficit in the balance of payments, a
'tight maney policy' or 'dear money.p6Iicy' is ,idoptl:d. Under 'dear
money' policy, central Ilwlll:lar'y Clulil()ritics raise "[ilc discount rate.
Consequently, under nonna1 conditions, the demand 'for
institutional funds for investment decreases. With the fall in
investment and through its multiplier effect, income of the people
decreases. lf lnarginal propensity to consume is greater than zero,
demand for goods and services decreases. The decrease in demand
also implies a simultaneous decrease in imports while other things
remain same. This is how 'a tight money policy' corrects deficit in
balance of payments.
The effcacy of 'tig:,t money policy' is however doubtful under
following conditions: (i) when rates of returns are much higher than
the increased bank rate due to inflationary conditions, (ii) when
investors have already affected their investment in anticipation of
increase in the rate of interest. The tight money policy is then
combined with open market operation, i.e., sale of government
bonds and securities. These two instruments together help to
reduce demand for capital and other goods. Therefore, if all goes
well then the deficit in the balance of payments is bound to
decrease.
Fiscal Policy
Fiscal policy as a tool of income regulation includes vanatlon in
taxation and public expenditure. Taxation reduces household
disposable income. Direct taxes directly transfer the houseilOld
income to the public reserves while indirectlaxes serve the same
purpose through increased prices of the taxed commodities. Direct
taxes reduce personal savings directly in a greater amount while
indirect taxe~ do it in a relatively smaller amount. Taxation reduces
the disposable income ofthe household and thereby the aggregate
demand including the demand for imports. Taxation also helps to
curtail investment by taxing capital at progressive rates.
The g~veinmeht can reduce income and demand also by
adopting the policy of surplus budgding in which the government
keeps its expenditure less than its revenue. Ll'~:>tion reduces
disposable income of household and public expenditure increases
household's income and their purchasing power. However,
multiplier effect of public expenditure is greater by one than the
multiolier effect of taxation. Therefore, while adopting surplus-
budget policy due consideration should be given to this fact. To
account for this fact, it is necessary that surplus is so largi.: that
the total cumulative effect of taxati?n on disposable income
exceeds the effect of public expenditure. The reduction in income
that will be necessary to achieve a certain given target of reducinG
balance of payments deficit depends on the rate foreign trade
multiplier. .
Exchange Depreciation and Devaluation
Reducing 'excess demand through price measures involves
changing relative prices of imports and exports. Relati';e prices of
imports and exports can be changed through exchange
depreciation and devaluation. Exchange depreciation refers to fall
in the value of home currency in terms of foreign currency and
devaluation refers to fall in the value of home currency in terms of
gold. However, ill terms of purchasing power, parity between
devaluation and depreciation turns out to be the same and its
impact on foreign demand is also the same. Therefore, we shall
consider them as one in their role of correcting adverse balance of
payments.
Devaluation and exchange depreciation change the relative
prices of imports and exports, i.e., import prices increase and
export prices decrease, though not necessarily in the proportion of
devaluation. As a result of change in relative prices of exports and
imports, the demand for imports decreases in the country, which
devalues its currency and foreign demand for its goods increases
provided foreign demand for imports is price elastic. Thus, if
devaluation or exchange depreciation is· effective, imports will
decrease and exports will increase. Country's payments for imports
would decrease and export earnings would increase. This
ultimately decreases the deficits in the balance of payments in due
course of time. However, whether expected results of devaluation
or exchange depreciation are achieved or not depends on the
following condition5.
The most important condition in this regard is the Marshall-
Lerner conditidh. The Marshall-Lerner condition states that
devaluation will . improve the balance of payments only if the
sum of elasticises of home demand for imports and foreign
demand for exports is greater than unity. If (he sum of
elasticises is less than unity, the balance of payments can be
improved through revaluation instead of devaluation.
Devaluation can be successful only if the alTectcd countries do
nol devalue their currency in retaliation.
Devaluation must not change the cost-price structure in favour
of imports.
Finally, the government ensures that inflation. which may be
the result of deyaluation, is kept undcr control, so that the
effect of devaluatibn is not counter-balanced by the effect of
inflation.
Direct Measure: Exchange Control
The exchange control refers to a set of restrictions imposed on the
international transactions and payments, by the government or the
exchange cotHrol authority. Exchange control may be partial,
confined to only few kinds of transactions or payments, or total
covering all kinds of international transactions depending on the
requirement of the country.
The main features of a full-fledged exchange control system are
as follows:
The government acquires, through the legislative
measures, a
Complete domination over the foreign exchange
transactions.
The government monopolises the purchase and sale of
foreign
exchange.
Law el iminates the sale and purchase of foreign exchange
by the
resid~nt individuals. Even holding foreign exchange
without informing the exchange control authority ;s
declared illegal.
All payments to the foreigners and receipts from them are
routed
through the exchange control authority or the authorised
agents.
Foreign exchange payments arc restricted, generally, to
the import
of essential goods and service such as food items, raw
materials, other essential industrial inputs like
petroleum products.
A system of rationing is adopted in the foreign exchange
allocation
for essential imports.
To ensure the effectiveness of the exchange control
system and to
prevent the possible evasion, strict, stringent laws like
FERA
and/COFEPOSA in India arc enactec.
The circuitous legal procedure of acquiring
import amI export
licences is brought in force. In the process, the
convertibility of the
home-currency is sacri ficed.
Why Exchange Control?

halance 01 plIYlllcnl diffcrs I'IldiclIlly (hllil lhe Indirect elHTt'di\'l'
nll'IISlIrl'·S. Wllik till" 1"lkl works through the markct forccs, the
fonncr works through a cOlllrol lIIechanism based on adhoc rules
and regulations. In contrast to the self-sustained and automatic
functioning of the market system, the exchange control requires a
cumbersome bureaucratic system of checks and controls. Yet,
many countries facing balance of payment deficits opt for
exchange control for lack of options. In fact, automatic adjustment
in the balance of payments requires the existence 0 I' thc
following conditions.
International competitive strength of the deficit countries.
A fairly high elasticity of demand for imports.
Perfectly competitive international market mechanism.
Absence of government intervention with the demand and
supply
conditions. .
The existence of these conditions has always been doubted.
Owing to differences in resource endowments technology, and the
level of industrial growth, countries differ in their economic
strength and their industries lack the competitiveness. The
protectionist policies adopted by various countries intervene with
international market mechanism. Besides, automatic method of
balance of payments adjustment requires a strict discipline,
economic strength and political will to bear the destabilising
shocks which the automatic method is expected to bring to a
country in the process of adjustment. Since these conditions
rarely exist, the efficacy of internati'onal market mechUl1ism to
bring automatic balance of payments adjustment is orten
doubted.
For these reasons, exchange control remains the last resort for the
countries under severe str<lin of balancc or payments dclicits. The
e:-:ch:\llge contn)1 is qid to possess a superior effectiveness in
providing solutions to the deficit problem. Besides, it insulates an
economy against thc impact of eeonOl'nir. nlleluOItioliS i'1' "~I
foreign countries. Another positive advantage or exchange control
lies II' \lS cfrcctivcness in dealing with the problem or capital
movements. The governlllCnl'S I monopoly over the roreign
exchange can eflectively stop or reduce the eapit:li t"i movements
by simply refusing to release foreign exchange for capital transrcr.
Many countries, i.e., Germany, Denmark and Argentina, adopted
exchange control during 1930s because of this advantage. Although
the exchange control is positively a superior method of dealing with
disequilibrium in th~ balance of payments, it docs not pro' -ide a
perman<.:nt solution to the basic cau~es of deficit problem.
Exchange control may no doubt provide solution to balance of payment
deficits, but it also creates following problems:
When restrictions on exchange control becomes wide spread then
large number of currencies are rendered inconvertible. This restricts
foreign trade and the gains from foreign 1rade are either lost or
reduced to a minimum.
Even after the interest of an economy is secured, i.e., external deficit
is rCll1ov<.:d and insulation of e<.:onomy against external influence
is complete; the exchange-control countries instead of giving up
exchange control feel lITe to gear their int<.:rnal policks, monetary
and fiscal, towards the promotion of economic growth, a<.:hieving full
employment and its maintenance. In doing so, they adopt easy
monetary and promotional fiscal policies. Consequently, income and
prices tend to rise, and inflationary trend is set in the economy.
Price also tends to rise, since in an insulted economy, import-
competing industries are not under compulsion to check cost
increases and to improve efficiency. As a result, exports become
relatively costlier and imports relatively cheaper and hence, exports
tend to shrink and imports tend to expand. These are the first
outcome of overvaluation of home-currency. The balance of payments
is no doubt maintained in equilibrium, but the init.ial advantage
gradually disappears.
The countries confronted with the problems arising out of exchange
control ,II'C forced to find new outlets for their exports and new sources of
imports. The dTorts in this direction give rise to bilateral trade· agreements
between the countries having common interest. The basic feature of the
bilateral trade ;Igreements is to accept each other's inconvertible currency
for exports and use the same Jor imports. Under the trade agreements, the
commodities and their quan~ilt'es or values should I also be specified.
Another outcome of exchange contr leading to bilateral trade agreement is
the emergence of disorderly cross cxcl ,anl',1.: r[lte~, i.e., the multiplicity of
inconsistent exchange rates. In other words, i .. IlIhl(;rii~)1<; currencies
have different exchange ratep betweeI: them. -
''l(in'illeonvertible currency has different exchange relation with the
countries .. ~ p,\ty to the bilateral trade agreement therefore, exchange
rates are not consis fent with each other. The multiplicity of inconsistent
exchange rates occom;;;s inevitable when countries having trade surplus
and deficits fix up official r;llt's frnlll timc to time dq1l'ndin!-,- nn their
requirelllents ,ll1d 1ll,Iintain it through arbitrary rules. Exchange rates
beconie multiple also because 'exchange arbitrage', i.e., the
simultaneous purchase and sale of exchange in di fferent markets,
becomes impossible.
Under the multiple exchange rate system, there may be a dual
exchange rate policy. In dual exchange rate policy, there is an
official rate for permissible private transactions and official
transactions and a market rate for all other kinds of transactions.
However, the multiple exchange rate system has its own
shortcomings .. The system adds complexity and uncertainty to
international transactions. Besides, it requires efficient and honest
administrative machinery in the absence of which it often leads to
inefficient use of resources. It is, therefore, desirable for the deficit
countries to first evaluate the consequence:>, efficacy and
pract'::ability of exchanre control and then decide on the course of
action. It has been suggested that exchange control, if adopted,
should be moderate and as temporary measure until the basic
solution to the problems of balance of payments deficit is obtaired.
The exchange control problem does not provide permanent solution
to the balance-of-payments deficit and therefore, it should be
adopted only with proper understanding.
