We consider repeated games with complete information and imperfect monitoring, where each player is assigned a fixed subset of players and only observes the moves chosen by the players in this subset. This structure is naturally represented by a directed graph. We prove that a generalized folk...

The set of payoffs associated to pure uniform equilibria of a repeated game with public observation is characterized in terms of the one shot-game. The key of the result is first, a study of the effect of undetectable deviations and second, the definition of new types of punishments using...

We exhibit a general class of interactive decision situations in which all the agents benefit from more information. This class includes as a special case the classical comparison of statistical experiments à la Blackwell. Copyright Springer-Verlag 2003
