We study two-player games played by two communities in an infinitely repeated anonymous random matching setting. It is well-known that despite the informational restrictions of this setting, for the prisoner’s dilemma, cooperation can be sustained in equilibrium through grim trigger strategies also called contagion” or “community enforcement” in this context. But, little is known beyond the prisoner’s dilemma when information transmission is minimal. In this paper we show that the ideas of community enforcement can indeed be applied far more generally.
