Document Summary

Firms want to charge higher prices to consumers that will be willing to pay that higher price and lower to those who will stop buying from them if the price increases: key element is elasticity: It is profit maximizing to charge a higher price to consumers who are relatively more price inelastic and charge a lower price to consumers who are more price sensitive/elastic. Conditions for price discrimination: firm must have market power. Perf comp firms do not: firm must be able to identify difference in willingness to pay between consumers, firm must be able to limit the resale of the product. Types of price discrimination: perfect price discrimination. Charge max amount each consumer is willing to pay. Stops producing when: p = mr = mc. Net benefits to society are maximized no dwl. This is efficient, but no equitable: quantity discrimination. Firm charges different price for large quantities than for small quantities.

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.

d. the firm must be a pure monopoly.

Question 4

If it could practice first-degree price discrimination, a firm with market power could earn:

Select one:

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

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.

Select the correct answer:

A (legal; natural) monopoly exists when one firm can meet the entire market demand at a lower average total cost than two or more firms could.

A monopoly that is able to sell different units of a good or service for different prices is a (natural-price; price-discriminating) monopoly.

The act of obtaining special treatment by the government to create an economic profit is called (government surplus; rent seeking).

Regulated firms have an incentive to inflate their costs under (rate of return; price cap) regulation.

The U.S. Postal Service has a (natural; legal) monopoly on first class mail delivery.

A (single-price; price discriminating) monopoly maximizes profit by producing the quantity at which marginal revenue equals marginal cost and then charging the maximum price that consumers are willing to pay for that quantity.

The key idea behind price discrimination is to convert (consumer surplus; producer surplus) into economic profit.
