2. Innitely repeated Prisoner's Dilemma game (8 points). Consider the following payoff matrix: Player2 C D A 10,10 60, -5 a) Find the Nash equilibrium assuming that this is a simultaneous, static (one-period) game. (2 points). b) Suppose the players know that this game will be repeated three times, so this is a threeperiod game. Can they achieve payoffs that are better than the static Nash equilibrium? Explain. (2 points). 0) What is the lowest discount rate for which the (ED) outcome can be sustained in an innitely repeated game if the players choose to play trigger strategies? (4 points)
