2 What effect does the number of firms in an oligopoly have on the characteristics of the market?

As the number of firms increases, the equilibrium quantity of goods provided increases and price falls; the market begins to resemble a competitive one

LOC: Oligopoly TOP: Cartels MSC: Applicative
4 Describe the source of tension between cooperation and self-interest in a market characterized by oligopoly Use an example of an actual cartel arrangement to demonstrate why this tension creates instability in cartels.ANS:
The source of the tension exists because total profits are maximized when oligopolists cooperate on price and quantity by operating as a monopolist However, individual profits can be gained by individuals cheating on their cooperative agreement This is why cooperative agreements among members of a cartel are inherently unstable This
is evident in the problem OPEC experiences in enforcing the cooperative agreement on production and price of crude oil
LOC: Oligopoly TOP: Cartels MSC: Interpretive
5 Describe the output and price effects that influence the profit-maximizing decision faced by a firm in an oligopoly market How does this differ from output and price effects in a monopoly market?
ANS:
Output effect: Price > Marginal cost => increased output will add to profit
Price effect: increased quantity is sold at a lower price => lower revenue (profit?)
An oligopolist must take into account how the output and price effects will be influenced by competitors' productiondecisions, or it must assume competitors' production will not change in response to its own actions
LOC: Oligopoly TOP: Profit maximization | Oligopoly MSC: Interpretive
Trang 56 Explain how the output effect and the price effect influence the production decision of the individual
oligopolist
ANS:
Since the individual oligopolist faces a downward-sloping demand curve, she realizes that if she increases output, alloutput must be sold at a lower market price As such, the revenue from selling the additional units at the lower market price must exceed the loss in revenue from selling all previous units at the new lower price Otherwise, profits will fall as output (production) is increased

7 Ford and General Motors are considering expanding into the Vietnamese automobile market Devise a simple prisoners' dilemma game to demonstrate the strategic considerations that are relevant to this decision
ANS:
The answer should present two strategies for each company, such as “Expand” and “Don’t Expand.” To be a prisoner’s dilemma, each firm needs a dominant strategy, but each firm choosing its dominant strategy results in an outcome that is jointly worse than if they both chose their other strategy A possible payoff table with payoffs (Ford,GM) is

8 Nike and Reebok (athletic shoe companies) are considering whether or not to advertise during the Super Bowl.Devise a simple prisoners' dilemma game to demonstrate the strategic considerations that are relevant to this decision Does the repeated game scenario differ from a single period game? Is it possible that a repeated game (without collusive agreements) could lead to an outcome that is better than a single-period game? Explain the circumstances in which this may be true
ANS:
The answer should show that if both shoe companies decide to advertise they will both be worse off than if they did not It should also show that each company has the individual incentive to advertise The dominant strategy of both companies will be to advertise, regardless of what the other is doing If the game is repeated more than once it is possible that the shoe companies will decide not to advertise in the hopes that the other company adequately understands the mutually beneficial gains that come from not advertising
9 Outline the purpose of antitrust laws What do they accomplish?
ANS:
The purpose of antitrust laws is to move markets toward a competitive equilibrium outcome These laws are used to prevent behavior that would lead to excessive market power by any single firm
LOC: Oligopoly TOP: Antitrust MSC: Interpretive
10 Explain the practice of resale price maintenance and discuss why it is controversial
ANS:
Resale price maintenance is a requirement by producers that retailers sell their product for a price specified by the manufacturer It is controversial because on the surface it appears to limit the ability of retailers to compete on the basis of price However, if the manufacturer does not exercise resale price maintenance a free-rider problem may become evident among the retailers and ultimately lead to lower profits for the manufacturer

Trang 611 Explain the practice of tying and discuss why it is controversial.
ANS:
Tying is the practice of bundling goods for sale It is controversial because it is perceived as a tool for expanding themarket power of firms by forcing consumers to purchase additional products However, economists are skeptical that a buyer's willingness to pay increases just because two products are bundled together In other words, simply bundling two products together doesn't necessarily add any value It is more accurately believed to be a form of price discrimination
