Question 1 Multiple Choice In theory, price discrimination decreases the monopolist's profits. decreases consumer surplus. increases deadweight loss. reduces the number of consumers who purchase the monopoly's product. Question 2 Multiple Choice Scenario 15-3 Black Box Cable TV is able to purchase an exclusive right to sell a premium movie channel (PMC) in its market area. Let's assume that Black Box Cable pays $150,000 a year for the exclusive marketing rights to PMC. Since Black Box has already installed cable to of all the homes in its market area, the marginal cost of delivering PMC to subscribers is zero. The manager of Black Box needs to know what price to charge for the PMC service to maximize her profit. Before setting price, she hires an economist to estimate demand for the PMC service. The economist discovers that there are two types of subscribers who value premium movie channels. First are the 5 points 5 points 4,000 die-hard TV viewers who will pay as much as $150 a year for the new PMC premium channel. Second, the PMC channel will appeal to about 20,000 occasional TV viewers who will pay as much as $20 a year for a subscription to PMC. Refer to Scenario 15-3.

Currently, there are plenty of seats on the subway, and it is never crowded. Its capacity far exceeds the needs of the city. After just a few years of operation, the shareholders of C.R. Evans experienced incredible rates of return on their investment, due to the profitability of the corporation. 5 points 5 points Refer to Scenario 15-1. C.R. Evans will continue to be a monopolist in the subway transportation industry only if population growth leads to an overcrowding of the subway cars. there are no new entrants to the market. demand for transportation services decreases. All of the above are correct. Question 10 Multiple Choice 5 points Which of the following is an example of a barrier to entry? (i)A key resource is owned by a single firm.

Question 15 Multiple Choice Scenario 16-4 Consider two cigarette companies, PM Inc. and Brown Inc. If neither company advertises, the two companies split the market and earn $50 million each. If they both advertise, they again split the market, but profits are lower by $10 million since each company must bear the cost of advertising. Yet if one company advertises while the other does not, the one that advertises attracts customers from the other. In this case, the company that advertises earns $60 million while the company that does not advertise earns only $30 million. 5 points 5 points Refer to Scenario 16-4. What is PM Inc.'s dominant strategy? To refrain from advertising regardless of whether Brown Inc. advertises To advertise only if Brown Inc. advertises To advertise only if Brown Inc. does not advertise To advertise regardless of whether Brown Inc. advertises Question 16 Multiple Choice 5 points An equilibrium in which each firm in an oligopoly maximizes profit, given the actions of its rivals, is called a general equilibrium. a dominant equilibrium. a Nash equilibrium. an oligopoly equilibrium. Question 17 Multiple Choice Table 16-11 B A Up Down Right (2, 2) (1, 3) Left (3, 1) (0, 0) 5 points Refer to Table 16-11. This table shows a game played between two players, A and B.

Question 20 Multiple Choice Table 16-16 Consider a small town that has two grocery stores from which residents can choose to buy a gallon of milk. The store owners each must make a decision to set a high milk price or a low milk price. The payoff table, showing profit per week, is provided below. The profit in each cell is shown as (Store 1, Store 2). Store 2 Store 1 Low Price High Price Low Price (500, 500) (100, 800) High Price (800, 100) (650, 650) 5 points Refer to Table 16-16.

Question 1 Multiple Choice Games that are played more than once generally lead to outcomes dominated purely by self-interest. lead to outcomes that do not reflect joint rationality. encourage cheating on cartel production quotas. make collusive arrangements easier to enforce. Question 2 Multiple Choice In game theory, a Nash equilibrium is an outcome in which each player is doing their best given the strategies chosen by the other players. an outcome in which no player wishes to change their chosen strategy given the strategies chosen by the other players. the outcome that occurs when all players have a dominant strategy. All of the above. Question 3 Multiple Choice 5 points 5 points 5 points When firms are faced with making strategic choices in order to maximize profit, economists typically use the theory of monopoly to model their behavior. the theory of aggressive competition to model their behavior. game theory to model their behavior. cartel theory to model their behavior. Question 4 Multiple Choice Scenario 16-4 Consider two cigarette companies, PM Inc. and Brown Inc. If neither company advertises, the two companies split the market and earn $50 million each. If they 5 points both advertise, they again split the market, but profits are lower by $10 million since each company must bear the cost of advertising.

In this case, the company that advertises earns $60 million while the company that does not advertise earns only $30 million. Refer to Scenario 16-4. In 1971, Congress passed a law that banned cigarette advertising on television. If cigarette companies are profit maximizers, it is likely that neither company opposed the ban on advertising. Brown Inc. sued the federal government on grounds that the ban constitutes a civil rights violation. both companies sued the federal government on grounds that the ban constitutes a civil rights violation. both companies retaliated with black-market operations.

Question 20 Multiple Choice With perfect price discrimination the monopoly eliminates all price discrimination by charging each customer the same price. the monopoly charges each customer an amount equal to the monopolist's marginal cost of production. the deadweight loss from monopoly is eliminated. consumer surplus is gained as monopoly profits are eliminated. 5 points
