Problem 2 [3 points] Consider the 16-times repeated version of the game described in Table 1 below: Table 1 A B C X 12, 4a +4 0,0 0, -2a Y 0, 0 4, 2a 18, -2a 1. If a = -1, find all of the subgame perfect equilibria of the repeated version of this game. Explain how you know you found them all. [2 points] 2. Would your answers be different if the game were repeated indefinitely? [1 point]
