1. The table below shows a prisoner's dilemma in normal form. Players 1 and 2 each choose between D and C. D C D 2,2 1,10 10, 1 5,5 Answer the following questions. Remember to explain your reasoning. (a) If the game is played only once, what is the equilibrium in dominant strategies? (b) If the game is played three times in a row, what action does each player choose in every round? Suppose that the game is repeated indefinitely. The players do not discount the future. How- ever, the game ends with probability p € (0, 1) after each round. Assume that each player uses the following grim-trigger strategy. Each player chooses C in the first round. Each player chooses C in the current round if both players chose C in every previous round. Each player chooses D in the current round if either player chose D in some previous round. (c) If p = 1, is it optimal for each player to use the grim-trigger strategy above given that the other player uses the grim-trigger strategy above? [Hint: compare…
