Research Abstract

We conduct theoretical analysis of the model of repeated games where sufficient conditions for a folk theorem (a general efficiency result) fail. Mainly in the model of partnerships under imperfect public monitoring and the model of cartel s with a small discount factor, we characterize the equilibrium which is most efficient in the sense of maximizing the players’ total payoffs. We also formulate a model of repeated games where monitoring is part of a player’s decision making, and present sufficient conditions for existence of cooperative equilibria which provide proper incentives about monitoring.
