2. A finitely repeated game. Consider the two-player game a b C d A 3,1 0,0 0,0 5,0 B 0,0 1,3 0,0 0,0 0,0 0,0 2,2 0,0 D 0.0 0,5 0,0 4,4 (a) Find all the pure-strategy Nash equilibria of this game. (b) Suppose that this game is played twice (i.e., played and then repeated once). Construct a pure- strategy SPE in which (D, d) is played in the first stage
