4. The following payoff matrix shows the profit payoff to firms A and B from combinations of
price strategies HI and LO.
A
НІ
LOW
B
HI
(6, 6)
(16, -5)
LOW
(-7, 15)
(0, 0)
(a) In a one period game, what strategy would each firm follow, and why? Determine the
equilibrium on the one-period game.
(b) Now assume the game is infinite in length. Firm B goes HI in period 1 and continues
with HI so long as A does as well. Firm A is deciding between HI and LO. Determine
the
range of discount rates for which HI is the better choice for Firm A.
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:
Suppose that Firm A and Firm B are independently deciding whether to sell at a low price or a high price. The payoff matrix below
shows the profits per year for each company resulting from the two price options.
Firm B High Price
Firm B Low Price
$5 million
$2 million
$3 million
$1 million
$4 million
$5 million
$2 million
$3 million

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.arrow_forward
