Exam 17: Oligopoly

Table 17-30 Imagine a small town in which only two residents, Abby and Brad, own wells that produce safe drinking water. Each week Abby and Brad work together to decide how many gallons of water to pump. They bring water to town and sell it at whatever price the market will bear. To keep things simple, suppose that Abby and Brad can pump as much water as they want without cost so that the marginal cost is zero. The weekly town demand schedule and total revenue schedule for water is shown in the table below: -Refer to Table 17-30. Discuss the difference between the monopoly outcome and the Nash equilibrium.

Table 17-20 Nadia and Maddie are two college roommates who both prefer a clean common space in their dorm room, but neither enjoys cleaning. The roommates must each make a decision to either clean or not clean the dorm room's common space. The payoff table for this situation is provided below, where the higher a player's payoff number, the better off that player is. The payoffs in each cell are shown as (payoff for Nadia, payoff for Maddie). -Refer to Table 17-20. What is Nadia's dominant strategy?

Table 17-34 Suppose that two oil companies - BP and Exxon - own adjacent natural gas fields. The profits that each firm earns depends on both the number of wells it drills and the number of wells drilled by the other firm. The table below lists each firm's individual profits: Exxon Drill one well Drill two wells -Refer to Table 17-34. Does Exxon have a dominant strategy? If so, describe it.

Table 17-20 Nadia and Maddie are two college roommates who both prefer a clean common space in their dorm room, but neither enjoys cleaning. The roommates must each make a decision to either clean or not clean the dorm room's common space. The payoff table for this situation is provided below, where the higher a player's payoff number, the better off that player is. The payoffs in each cell are shown as (payoff for Nadia, payoff for Maddie). -Refer to Table 17-20. If Maddie chooses not to clean, then Nadia will

Figure 17-4. Aaron and Ed are roommates. After a big snowstorm, their driveway needs to be shoveled. Each person has to decide whether to take part in shoveling the driveway. At the end of the day, either the driveway will be shoveled (if one or both roommates take part in shoveling), or it will remain unshoveled (if neither roommate shovels). With happiness measured on a scale of 1 (very unhappy) to 10 (very happy), the possible outcomes are as follows: -Refer to Figure 17-4. The dominant strategy for Ed is to

The profits that each firm earns depends on both the number of wells it drills and the number of wells drilled by the other firm. The table below lists each firm's individual profits: Exxon Drill one well Drill two wells -Refer to Table 17-34. Is there a Nash equilibrium? If so, describe it.

Table 17-1 Imagine a small town in which only two residents, Rochelle and Alec, own wells that produce safe drinking water. Each week Rochelle and Alec work together to decide how many gallons of water to pump. They bring the water to town and sell it at whatever price the market will bear. To keep things simple, suppose that Rochelle and Alec can pump as much water as they want without cost so that the marginal cost of water equals zero. The weekly town demand schedule and total revenue schedule for water is shown in the table below: 21. -Refer to Table 17-1. If this market for water were perfectly competitive instead of monopolistic, what price would be charged?

Briefly describe the practice of predatory pricing.

Figure 17-5. Two companies, ABC and QRS, are sellers in the same market. Each company decides whether to charge a high price or a low price. In the figure, the dollar amounts are payoffs and they represent annual profits for the two companies. -Refer to Figure 17-5. If the two companies make their pricing decisions independently, then it is likely that QRS will

Two suspected drug dealers are stopped by the highway patrol for speeding. The officer searches the car and finds a small bag of marijuana and arrests the two. During the interrogation, each is separately offered the following: "If you confess to dealing drugs and testify against your partner, you will be given immunity and released while your partner will get 10 years in prison. If you both confess, you will each get 5 years." If neither confesses, there is no evidence of drug dealing, and the most they could get is one year each for possession of marijuana. If each suspected drug dealer follows a dominant strategy, what should he/she do?

Table 17-10 The table shows the demand schedule for a particular product. -Refer to Table 17-10. If this market is perfectly competitive and the marginal cost is constant at $40 per unit, then how much output will be produced?

Scenario 17-3. Consider two countries, Kinglandia and Rovinastan, that are engaged in an arms race. Each country must decide whether to build new weapons or to disarm existing weapons. Each country prefers to have more arms than the other because a large arsenal gives it more influence in world affairs. But each country also prefers to live in a world safe from the other country's weapons. The following table shows the possible outcomes for each decision combination. The numbers in each cell represent the country's ranking of the outcome (10 = best outcome, 1 = worst outcome). -Refer to Scenario 17-3. If Rovinastan chooses to disarm its existing weapons, then Kinglandia will

The manufacturer of South Face sells jackets to retail stores for $120 each, and it requires the retail stores to charge customers $150 per jacket. Any retailer that charges less than $150 would violate its contract with South Face. 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. If grocery store 2 sets a low price, what price should grocery store 1 set? And what will grocery store 1's payoff equal?

Resale price maintenance involves a firm

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. Which of the following statements is correct?

Which government entity is charged with investigating and enforcing antitrust laws?
