Содержание слайда: REVISITING THE MARKET EQUILIBRIUM
Do the equilibrium price and quantity maximize the total welfare of buyers and sellers?
Market equilibrium reflects the way markets allocate scarce resources.
Whether the market allocation is desirable can be addressed by welfare economics.
№4 слайд![Welfare Economics Welfare](/documents_6/3c2de31b0d4e9aea7d7ad1f913abf3fd/img3.jpg)
Содержание слайда: Welfare Economics
Welfare economics is the study of how the allocation of resources affects economic well-being.
Buyers and sellers receive benefits from taking part in the market.
The equilibrium in a market maximizes the total welfare of buyers and sellers.

Содержание слайда: Welfare Economics
Equilibrium in the market results in maximum benefits, and therefore maximum total welfare for both the consumers and the producers of the product.

Содержание слайда: MARKET EFFICIENCY
Consumer surplus and producer surplus may be used to address the following question:
Is the allocation of resources determined by free markets in any way desirable?

Consumer Surplus
= Value to buyers – Amount paid by buyers
and

Three Insights Concerning Market Outcomes
Free markets allocate the supply of goods to the buyers who value them most highly, as measured by their willingness to pay.
Free markets allocate the demand for goods to the sellers who can produce them at least cost.
Free markets produce the quantity of goods that maximizes the sum of consumer and producer surplus.

№37 слайд![Evaluating the Market](/documents_6/3c2de31b0d4e9aea7d7ad1f913abf3fd/img36.jpg)
Содержание слайда: Evaluating the Market Equilibrium
Because the equilibrium outcome is an efficient allocation of resources, the social planner can leave the market outcome as he/she finds it.
This policy of leaving well enough alone goes by the French expression laissez faire.
№38 слайд![Evaluating the Market](/documents_6/3c2de31b0d4e9aea7d7ad1f913abf3fd/img37.jpg)
Содержание слайда: Evaluating the Market Equilibrium
Market Power
If a market system is not perfectly competitive, market power may result.
Market power is the ability to influence prices.
Market power can cause markets to be inefficient because it keeps price and quantity from the equilibrium of supply and demand.
№39 слайд![Evaluating the Market](/documents_6/3c2de31b0d4e9aea7d7ad1f913abf3fd/img38.jpg)
Содержание слайда: Evaluating the Market Equilibrium
Externalities
created when a market outcome affects individuals other than buyers and sellers in that market.
cause welfare in a market to depend on more than just the value to the buyers and cost to the sellers.
When buyers and sellers do not take externalities into account when deciding how much to consume and produce, the equilibrium in the market can be inefficient.
№40 слайд![Summary Consumer surplus](/documents_6/3c2de31b0d4e9aea7d7ad1f913abf3fd/img39.jpg)
Содержание слайда: Summary
Consumer surplus equals buyers’ willingness to pay for a good minus the amount they actually pay for it.
Consumer surplus measures the benefit buyers get from participating in a market.
Consumer surplus can be computed by finding the area below the demand curve and above the price.
№41 слайд![Summary Producer surplus](/documents_6/3c2de31b0d4e9aea7d7ad1f913abf3fd/img40.jpg)
Содержание слайда: Summary
Producer surplus equals the amount sellers receive for their goods minus their costs of production.
Producer surplus measures the benefit sellers get from participating in a market.
Producer surplus can be computed by finding the area below the price and above the supply curve.
№42 слайд![Summary An allocation of](/documents_6/3c2de31b0d4e9aea7d7ad1f913abf3fd/img41.jpg)
Содержание слайда: Summary
An allocation of resources that maximizes the sum of consumer and producer surplus is said to be efficient.
Policymakers are often concerned with the efficiency, as well as the equity, of economic outcomes.
№43 слайд![Summary The equilibrium of](/documents_6/3c2de31b0d4e9aea7d7ad1f913abf3fd/img42.jpg)
Содержание слайда: Summary
The equilibrium of demand and supply maximizes the sum of consumer and producer surplus.
This is as if the invisible hand of the marketplace leads buyers and sellers to allocate resources efficiently.
Markets do not allocate resources efficiently in the presence of market failures.
