Is the game shown by Figure 11.3 in the chapter (not this appendix) a zero-sum game or is it a positive-sum game? How can you tell? Are there dominant strategies in this game? If so, what are they? What cell represents a Nash equilibrium and why? Explain why it is so difficult for Uptown and RareAir to achieve and maintain a more favorable cell than the Nash equilibrium in this single-period pricing game.
Suppose that there are two firms in a market, firm 1 and firm 2. The marketis declining in size. The game starts in period 0, and the firms can compete in periods 0, 1,2, 3, ... (i.e., indefinitely) if they so choose. Duopoly profits in period t for firm 1 are equalto 105 −10t, and they are 10.5 −t for firm 2. Monopoly profits (those if a firm is the onlyone left in the market) are 510 −25t for firm 1 and 51 −2t for firm 2. At the start of eachperiod, each firm must decide either to “stay in” or “exit” if it is still active (they do sosimultaneously if both are still active). Once a firm exits, it is out of the market forever andearns zero in each period thereafter. Firms maximize their (undiscounted) sum of profits.What is this game’s subgame perfect Nash equilibrium?
Newfoundland’s fishing industry has recently declined sharply due to overfish- ing, even though fishing companies were supposedly bound by a quota agree- ment. If all fishermen had abided by the agreement, yields could have been maintained at high levels. LO4
Model this situation as a prisoner’s dilemma in which the players are Company A and Company B and the strategies are to keep the quota and break the quota. Include appropriate payoffs in the matrix. Explain why overfishing is inevitable in the absence of effective enforcement of the quota agreement.
Provide another environmental example of a prisoner’s dilemma.
In many potential prisoner’s dilemmas, a way out of the dilemma for a would-be cooperator is to make reliable character judgments about the trustworthiness of potential partners. Explain why this solution is not avail-
able in many situations involving degradation of the environment.

Player 2 observes player 1’s move and makes her move; if the move by player 1 is A, then player 2 can take three actions, X, Y or Z, if the move by player 1 is B, then player 2 can take of of two actions, U or V.

If neither of you advertises, you will each earn 20 million in profits. However, if one of you advertises and the other does not, the firm that advertises will earn 10 million and the non-advertising firm will earn 16 million.

- Suppose Toyota and Honda must decide whether to make a new kind of side-impact airbags standard equipment on all models. Side impact-airbags raise the price of each automobile by $1000. If both firms make side-impact airbags standard equipment, each company will earn profits of $2.5 billion. If neither company adopts the side-impact airbag technology, each company will earn $1 billion (due to lost sales to other automakers). If one company adopts the technology as standard equipment and the other does not, the adopting company will earn a profit of $3 billion and the other company will lose $1.5 billion. If you were a decision maker at Honda, would you make side-impact airbags standard equipment?arrow_forward3. Describe some interaction your company has with another entity (firms producing complementary or substitute products, upstream sup- pliers, or downstream customers), or between internal divisions within your firm that can be described as a sequential or simultaneous game. Diagram the strategies, players, and compute payoffs as best you can. Compute the Nash equilibria. What can you do to change the rules of the game to your advantage? Compute the profit consequences of your advice.arrow_forwardNext, explain how it can be applied to the decisions that have to be made in an oligopoly. What specifically is the decision to be made by each seller in an oligopoly? How does each possible outcome in the prisoners' dilemma map into an outcome in an oligopoly? What do you think each seller's dominant strategy will be? Examine and discuss how the role of communication, specifically the lack of communication, can lead to an outcome that is worse for the players. (Of course, it is against U.S. law for the sellers to conspire to make the market less competitive!) Can you think of other examples of how the prisoners' dilemma could be applied to business decision making?

- 11 21. Imagine an N firm oligopoly for "nominally differentiated" goods. That is, each of the N firms produces a product that "looks" different from the products of its competitors, but that "really" isn't any different. However, each firm is able to fool some of the buying public. Specifically, each of the N firms (which are identical and have zero marginal cost of production) has a captive market -consumers who will buy only from that firm. The demand generated by each of these captive markets is given by the demand function Pn A- Xn , where Xn is the amount supplied to this captive market and Pn is the price of the production of firm n. There is also a group of intelligent consumers who realize that the products are really undifferentiated. These…arrow_forwardWhat is the distinguishing characteristics of oligopoly in relation to the other forms of the other market organizations? What is its significance?
