چکیده

This paper continues the study of a new class of repeated games with imperfect public monitoring launched by Sannikov (2007). I provide a new characterization of self-generating sets for a class of games in continuous time and Brownian information. This new characterization relies on partial differential equation techniques. Our approach gives a geometric characterization of the set of perfect public equilibrium payoffs, similar to the 2-player characterization obtained by Sannikov (2007) who obtains a curvature relation through a direct argument. Our characterization via partial differential equations is obtained by first identifying self-generating sets as stochastically viable under the dynamic determining the continuation payoff process induced by the players’ strategies. Based on this formal identification we use viscosity solution techniques to derive a geometric characterization of the boundary of self-generating sets. In case of two players my characterization reduces to the result reported by Sannikov (2007), relating the curvature parameters of a set to incentives.

Repeated Games Where the Payoffs and Monitoring Structure Are Unknown

This paper studies repeated games with imperfect public monitoring where the players are uncertain both about the payoff functions and about the relationship between the distribution of signals and the actions played. We introduce the concept of perfect public ex-post equilibrium (PPXE), and show that it can be characterized with an extension of the techniques used to study perfect public equil...

Learning from private information in noisy repeated games

We study the perfect type-contingently public ex-post equilibrium (PTXE) of repeated games where players observe imperfect public signals of the actions played, and both the payoff functions and the map from actions to signal distributions depends on an unknown state. The PTXE payoffs when players are patient are determined by the solutions to a family of linear programming problems. Using this...
