Characterizing belief-free review-strategy equilibrium payoffs under conditional independence

Abstract

This paper proposes and studies a tractable subset of Nash equilibria, belief-free review-strategy equilibria, in repeated games with private monitoring. The payoff set of this class of equilibria is characterized in the limit as the discount factor converges to one for games where players observe statistically independent signals. As an application, we develop a simple sufficient condition for the existence of asymptotically efficient equilibria, and establish a folk theorem for N-player prisonerʼs dilemma. All these results are robust to a perturbation of the signal distribution, and hence remain true even under almost-independent monitoring.
