LESSON 1: CIRCULAR FLOW

Standards

SSEMI1 Describe how households and businesses are interdependent and interact through flows of goods, services, resources, and money.

a. Illustrate a circular flow diagram that includes the product market, the resource (factor) market, households, and firms.

b. Explain the real flow of goods, services, resources, and money between and among households and firms.

Key Questions

• What are the two main sectors of the economy?

• What do households need businesses for?

• What do businesses need households for?

• What does the Circular Flow Model (CFM) demonstrate?

• What is the resource, or factor, market?

• What is the product market?

Households and Firms

The free market economy is powered by the “household” and the “firm”…

Household—a person or group of persons living in the same residence. These are the CONSUMERS.

Firm—an organization that uses resources to produce a product, which it sells. Firms are the PRODUCERS.

The Factor Market

• Firms purchase factors of production from households…

• Land, Labor & Human Capital.

• This is the factor market—

• The place where firms purchase land, labor, human capital and physical capital.

The Product Market

The goods and services that firms produce…

Are sold in the Product Market…

And purchased by households…

With the money they received from firms in the factor market.

LESSON 2: SUPPLY AND DEMAND

Standards

SSEMI2 Explain how the law of demand, the law of supply, and prices work to determine production and distribution in a market economy.

a. Define the law of supply and the law of demand.

b. Distinguish between supply and quantity supplied, and demand and quantity demanded.

Connection to Circular Flow Model

1. Do individuals supply or demand?

2. Do business supply or demand?

3. Who demands in the product market?

4. Who supplies in the product market?

26

Key Questions

• What is the difference between a change in demand versus a change in quantity demanded?

• What is the difference between a change in supply versus a change in quantity supplied?

• Where do you find the market clearing price?

• How do buyers impact prices?

DEMAND DEFINED

28

What is Demand?

Demand is the different quantities of goods

that consumers are willing and able to buy at

different prices.(Ex: Bill Gates is able to purchase a Ferrari, but if

he isn’t willing he has NO demand for one)

What is the Law of Demand?

There is an INVERSE relationship between

price and quantity demanded

LAW OF DEMANDAs Price Falls…

…Quantity Demanded Rises

As Price Rises…

…Quantity Demanded Falls

Why does the Law of Demand occur?

The law of demand is the result of three

separate behavior patterns that overlap:

1.The Substitution effect

2.The Income effect

3.The Law of Diminishing Marginal Utility

We will define and explain each…

31


If the price goes up for a product, consumer buy less of that product and more of another substitute product (and vice versa)

If the price goes down for a product, the purchasing power increases for consumers -allowing them to purchase more.

32

1. The Substitution Effect

2. The Income Effect


• Utility = Satisfaction• We buy goods because we get utility from them• The law of diminishing marginal utility states that as

you consume more units of any good, the additional satisfaction from each additional unit will eventually start to decrease

• In other words, the more you buy of ANY GOOD the less satisfaction you get from each new unit.

Discussion Questions:

1. What does this have to do with the Law of Demand?

2. How does this effect the pricing of businesses?

Graphing Demand

35

The Demand Curve• A demand curve is a graphical representation of a

demand schedule.

• The demand curve is downward sloping showing the inverse relationship between price (on the y-axis) and quantity demanded (on the x-axis)

• When reading a demand curve, assume all outside

factors, such as income, are held constant.

Let’s draw a new demand curve for cereal…

LESSON 3: CHANGE IN QUANTITY DEMANDED

Standards


b. Identify the determinants (shifters) of demand (e.g., changes in related goods, income, consumer expectations, preferences/tastes, and number of consumers) and illustrate the effects on a supply and demand graph.

Key Questions

• List the non-price determinants (shifters) of demand and define each one.

• Provide an example of a complementary good.

• How does the substitution effect impact demand?

• What impact do changes in consumer income have on demand?

What Causes a Shift in Demand?

5 Shifters (Determinates) of Demand:

1.Tastes and Preferences

2.Number of Consumers

3.Price of Related Goods

4.Income

5.Future Expectations

Changes in PRICE don’t shift the curve. It

only causes movement along the curve.53

Prices of Related Goods

2. Complements are two goods that are bought

and used together. – If the price of one increase, the demand for the

other will fall. (or vice versa)

– Ex: If price of skis falls, demand for ski boots will...

1. Substitutes are goods used in place of one

another. – If the price of one increases, the demand for the

other will increase (or vice versa)

– Ex: If price of Pepsi falls, demand for coke will…

The demand curve for one good can be affected by a

change in the price of ANOTHER related good.

LESSON 4: SUPPLY AND DEMAND

Standards


a. Identify the determinants (shifters) of supply (e.g., changes in costs of productive resources, government regulations, number of sellers, producer expectations, technology, and education) and illustrate the effects on a supply and demand graph.

Key Questions

• List the non-price determinants (shifters) of supply and define each one.

• What impact does input costs have on supply of a good/service?

• What impact does government regulation and taxes have on supply of a good/service?

• How do technology investments increase supply?

Supply DefinedWhat is supply?

Supply is the different quantities of a good that sellers

are willing and able to sell (produce) at different prices.

What is the Law of Supply?

There is a DIRECT (or positive) relationship between

price and quantity supplied.

•As price increases, the quantity producers make

increases

•As price falls, the quantity producers make falls.

Why? Because, at higher prices profit seeking

firms have an incentive to produce more.

6 Shifters (Determinants) of Supply

1. Cost of resources

2. Number of Sellers

3. Technology

4. Government regulation: Taxes &

SubsidiesSubsidies

A subsidy is a government payment that supports a business or market.Subsidies cause the supply of a good to increase.

TaxesThe government can reduce the

supply of some goods by placing anexcise tax on them. An excise taxis a tax on the production or sale of

a good.

RegulationRegulation occurs when the

government steps into a market toaffect the price, quantity, or quality of

a good. Regulation usually raisescosts.

5. Education

6. Producer expectationChanges in PRICE don’t shift the curve. It only

causes movement along the curve. 86

Supply and Demand AnalysisEasy as 1, 2, 3

1. Before the change:• Draw supply and demand

• Label original equilibrium price and quantity

2. The change:• Did it affect supply or demand first?

• Which determinant caused the shift?

• Draw increase or decrease

3. After change:• Label new equilibrium?

• What happens to Price? (increase or decrease)

• What happens to Quantity? (increase or decrease)

LESSON 6: PRICE FLOORS AND CEILINGS

Standards


c. Explain and illustrate on a graph how prices set too high (e.g., price floors) create surpluses, and prices set too low (e.g., price ceilings) create shortages.

Key Questions

• What is a government price floor?

• What is a government price ceiling?

• What is the result of a price floor?

• What is the result of a price ceiling?

#1-PRICE CONTROLSWho likes the idea of having a price ceiling on

gas so prices will never go over $1 per gallon?

111

Price Ceiling= ShortageDisequilibrium

• Pc- Central Authority sets a Price Ceiling below the Equilibrium Price (Pe).

• Quantity Supplied (Qs) is less than Quantity Demanded (Qd) causing a shortage.

• To Calculate a Shortage: Quantity Supplied minus Quantity Demanded

Practice Questions1. Which of the following will occur if a legal price floor is

placed on a good below its free market equilibrium?

A. Surpluses will develop

B. Shortages will develop

C. Underground markets will develop

D. The equilibrium price will remain the same

above the equilibrium price

B. A price floor causes a surplus if the price floor is below

the equilibrium price

C. Price ceilings and price floors result in a misallocation of

resources

D. Price floors above equilibrium cause a shortage

LESSON 7: BUSINESS TYPES AND MARKET STRUCTURES

StandardsSSEMI3 Explain the organization and role of business and analyze the four types of market structures in the U.S. economy.a. Compare and contrast three forms of business

organization—sole proprietorship, partnership, and corporation with regards to number of owners, liability, lifespan, decision making, and taxation.

b. Identify the basic characteristics of monopoly, oligopoly, monopolistic competition, and pure (perfect) competition with regards to number of sellers, barriers to entry, price control, and product differentiation.

Key Questions

• What are the four market structures in a mixed-market economy?

• Who has the most control over the price of their product, and why?

• What is an example of an oligopoly?

• What is an example of monopolistic competition?

• What are the three types of business?
