EXERCISE 407.1 (Tit-for-tat as a subgame perfect equilibrium in the infinitely re- peated Prisoner's Dilemma) Consider the infinitely repeated Prisoner's Dilemma in which the payoffs of the component game are those given in Figure 407.1. Show that (tit-for-tat,tit-for-tat) is a subgame perfect equilibrium if and only if y - x = 1 and 8 = 1/x. (Use the fact that subgame perfect equilibria have the one-deviation property.)
