18. Answer the next question based on the payoff matrix for a two-firm oligopoly where the
numbers represent the firms' respective profits given each of their pricing strategies:
FIRM Y
O $ 800,000
O $1,000,000
O $1,450,000
Strategies:
High-price
If both firms collude to maximize joint profits,
O $1,250,000
FIRM X
High-price
X = $625,000
Y = $625,000
Low-price X = $275,000
Y = $725,000
Low Price
X = $725,000
Y = $275,000
X = $400,000
Y = $400,000
tal profits for the two firms will be:
5. The following represents the payoffs in a one period game in prices HI and LO.
A
HI
LOW
B
HI
(100, 100)
(200,0)
LOW
(0, 200)
(50, 50)
(a) If A and B were playing this game only once, what strategy should A choose, and why?
(b) A and B are playing the same game an infinite number of times and each has a discount rate
of 50% (.50). Firm B adopts a trigger strategy and selects HI in the first round. What would be
A's present value of profits from cooperation (HI)? What would be its present value from
cheating (LO)? Would A choose to cooperate or cheat?
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.
