Document Summary

A tax on a good reduces the welfare of buyers and sellers of the good, and the reducion in consumer and producer surplus usually exceeds the revenue raised by the government. The fall in total surplus the sum of consumer surplus, producer surplus, and tax revenue is called the deadweight loss of the tax. Taxes have deadweight losses because they cause buyers to consume less and sellers to produce less, and this change in behavior shrinks the size of the market below the level that maximizes total surplus. Because the elasiciies of supply and demand measure how much market paricipants respond to market condiions, larger elasiciies imply larger deadweight losses. As a tax grows larger, it distorts incenives more, and its deadweight loss grows larger. Tax revenue irst rises with the size of a tax. Eventually, however, a larger tax reduces tax revenue because it reduces the size of the market.

Why is there a deadweight loss associated with subsidy payments?
A) There is no deadweight loss from a subsidy.
B) Quantity supplied is less than the equilibrium amount, so consumers and producers lose surplus value on those units that are no longer produced.
C) Quantity supplied exceeds the equilibrium amount, and consumer willingness to pay for these additional units is smaller than the marginal cost of producing them.
D) The subsidy payment does not distort quantities in the market, but the government cost exceeds consumer willingness to pay for the quantity demanded.

Question 1

The amount of profit that can be achieved using uniform pricing is __________ the profit that can be achieved from price discrimination because of _______.

Select one:

a. greater than; the cost of trying to determine every single consumer's individual demand (willingness to pay) is prohibitively expensive.

b. less than; uniform pricing is more costly so the ATC and AVC curves are higher than they are under price discrimination.

c. equal to; the TR and TC curves are equivalent under either pricing scheme, so there is no profit advantage to either scheme.

d. less than; total demand includes people who would be willing to pay more than, as well as less than, the uniform market price.

Question 2

A firm selling in two markets is practicing price discrimination:

Select one:

a. when it refuses to sell the good to some group of consumers.

b. anytime it charges different consumers different prices.

c. when it charges the same price to different consumers as long as they differ in their demand for the good.

d. when it is charging different consumers, different prices, and the price difference is not based upon cost differences.

Question 3

To successfully practice price discrimination:

Select one:

a. consumers in two separate markets must have identical demand.

b. the firm must possess market power.

c. it must be easy for consumers in one market to sell to consumers in the other market.

b. an area half the size of its monopoly power under uniform pricing.

c. its typical monopoly profit as well as the area which, under uniform pricing, would represent consumer surplus.

d. its typical monopoly profit as well as the area which, under uniform pricing, would represent consumer surplus and the deadweight loss associated with market power.
