This paper examines a model of the prisoner's dilemma in which the nature of the Nash equilibria of the game can be varied. Two equilibrium indices are derived and are compared with two cooperation indices proposed by Rapoport and Chammah (1965). Preliminary experimental results indicate that the nature of the equilibria of a game affect the amount of cooperation.
