Collusion through mediated communication in repeated games with imperfect private monitoring

Abstract

This paper studies repeated games with imperfect private monitoring when there exists a third-party mediator who coordinates play by giving non-binding instructions to players on which action to take and by collecting their private information. The paper presents a Nash-threat folk theorem for a communication equilibrium based on such mediation when monitoring is jointly $\epsilon$ -perfect in the sense that every player is almost perfectly monitored collectively by other players.
