Prisoner's dilemma

2. No Cooperation for Small S In lecture, we argued that cooperative equilibria exist in the repeated prisoner's dilemma if and only if 6 2 6. In problem 1, you showed that we can have a Nash equilibrium in which both players always cooperate (specifically, the equilibrium in which both players play grim trigger) if 6 2 6. In this problem, we will show that if o
