Scenario 17-4. 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. -Refer to Scenario 17-4. The likely outcome of this game is that PM Inc. earns

How does the prisoners' dilemma game apply to real­life situations?

Table 17-9 The table shows the demand schedule for a particular product. -Refer to Table 17-9. Suppose the market for this product is served by two firms that have formed a cartel. What price will the cartel charge in this market if the marginal cost of production is $0?

Table 17-12 The table shows the town of Driveaway's demand schedule for gasoline. Assume the town's gasoline seller(s) incurs a cost of $2 for each gallon sold, with no fixed cost. -Refer to Table 17-12. If there are exactly five sellers of gasoline in Driveaway and if they collude, then which of the following outcomes is most likely?

Policymakers should be aggressive in using their powers to place limits on firm behavior, because business practices that appear to reduce competition never have any legitimate purposes.

Table 17-17 This table shows a game played between two firms, Firm A and Firm B. In this game each firm must decide how much output (Q) to produce: 2 units or 3 units. The profit for each firm is given in the table as (Profit for Firm A, Profit for Firm B) . -Refer to Table 17-17. In this game,

Suppose that Makemoney Movies produces two new films - The Hulk and The Piano. Makemoney offers theaters the two films together at a single price but will not supply the movies separately. What do economists call this business practice?

Table 17-19 Consider a small town that has two grocery stores from which residents can choose to buy a loaf of bread. The store owners each must make a decision to set a high bread price or a low bread price. The payoff table, showing profit per week, is provided below. The profit in each cell is shown as (Store 1, Store 2) . -Refer to Table 17-19. What is grocery store 1's dominant strategy?

As a group, oligopolists would always be better off if they would act collectively

To be successful, a cartel must

Scenario 17-6 Assume that a local telecommunications company sells high speed internet access and cable television. The company's only two customers are Taylor and Tim. Taylor is willing to pay $50 per month for high speed internet access and $50 per month for cable television. Tim is willing to pay only $20 per month for high speed internet access, but is willing to pay $70 per month for cable television. Assume that the telecommunications company can provide each of these products at zero marginal cost. -Refer to Scenario 17-6. How much additional profit can the telecommunications company earn by switching to the use of a tying strategy to price high speed internet access and cable television rather than pricing these goods separately?

Table 17-3 Imagine a small town in a remote area where only two residents, Maria and Miguel, own dairies that produce milk that is safe to drink. Each week Maria and Miguel work together to decide how many gallons of milk to produce. They bring milk to town and sell it at whatever price the market will bear. To keep things simple, suppose that Maria and Miguel can produce as much milk as they want without cost so that the marginal cost is zero. The weekly town demand schedule and total revenue schedule for milk is shown in the table below: -Refer to Table 17-3. If this market for milk were perfectly competitive instead of monopolistic, how many gallons of milk would be produced and sold?

Figure 17-2. Two companies, Acme and Pinnacle, each decide whether to produce a good quality product or a poor quality product. In the figure, the dollar amounts are payoffs and they represent annual profits for the two companies. -Refer to Figure 17-2. The more frequently this game is played, the more likely it is that

For a firm, strategic interactions with other firms in the market become more important as the number of firms in the market becomes larger.

Juan Pablo and Zak are competitors in a local market. Each is trying to decide if it is better to advertise on TV, on radio, or not at all. If they both advertise on TV, each will earn a profit of $8,000. If they both advertise on radio, each will earn a profit of $14,000. If neither advertises at all, each will earn a profit of $20,000. If one advertises on TV and other advertises on radio, then the one advertising on TV will earn $12,000 and the other will earn $10,000. If one advertises on TV and the other does not advertise, then the one advertising on TV will earn $22,000 and the other will earn $4,000. If one advertises on radio and the other does not advertise, then the one advertising on radio will earn $24,000 and the other will earn $8,000. If both follow their dominant strategy, then Juan Pablo will

Table 17-11 Only two firms, ABC and XYZ, sell a particular product. The table below shows the demand curve for their product. Each firm has the same constant marginal cost of $8 and zero fixed cost. -Refer to Table 17-11. If this market were perfectly competitive instead of oligopolistic, what quantity would be produced?
