Three Fundamental Questions

• What goods and services should be produced

and how?

• How much of each type of good and service

should be produced?

• How should these goods and services be

distributed among members in society?

MARKET

Market

Under certain conditionsUnder certain conditions markets can lead to

a:

• Technically

• Cost-effectively and

• Allocatively

Efficient allocation of resources.

PricesPrices Ensure That:

• On the production sideOn the production side resources are

used in their most productive way

• On the consumption sideOn the consumption side goods go to

those who value them most

Efficiency-equity Relationship

Individual ability and willingness to pay

Conditions for a Well-functioning Market1- Production Side

• Many producers

• Free entry and exit of producers

• Low fixed cost

• No production externality

Conditions for a Well-functioning Market2- Consumption Side

• Informational symmetry

• No consumption externality

• No dominant consumer

Externality

• Production externalityProduction externality

Social cost = Private cost + E

• Consumption externalityConsumption externality

Social benefit = Private benefit ± E

Determinants of Supply

• Price

• Production cost

production continues to increase to the point

where marginal costmarginal cost equals marginal revenuemarginal revenue

Determinants of Demand

• Price

• Tastes, preferences and needs

• Income

• Price of complementary/substitute goods

MSC = MPC = P = MPB = MSBMSC = MPC = P = MPB = MSB

Efficiency of the Market

• Consumers’ surplus:

Consumers’ value – Price

• Producers’ surplus:

Price – Actual production cost
