Bayesian Repeated Games
Résumé
We consider Bayesian games, with independent private values, in which uniform punishment strategies are available. We establish that the Nash equilibria of the Bayesian infinitely repeated game without discounting are payoff equivalent to tractable separating (i.e., completely revealing) equilibria and can be achieved as interim cooperative solutions of the initial Bayesian game. We also show, on a public good example, that the set of Nash equilibrium payoffs of the undiscounted game can be empty, while limit Nash equilibrium payoffs of the discounted game, as players become infinitely patient, do exist.
