The motivation of this paper comes from repeated games with incomplete information and imperfect monitoring. It concerns the existence, for any payoff function, of a particular equilibrium (called completely revealing) allowing each player to learn the state of nature. We consider thus an...

We study information transmission between informed experts and an uninformed decision-maker who only takes binary decisions. In the single expert case, we show that information transmission can only be relatively poor. Hence, even sophiscated communication games do not yield equilibria which (ex...

This paper characterizes geometrically the sets of all Nash and perfect Bayesian equilibrium payoffs achievable with unmediated communication in persuasion games, i.e., games with an informed expert and an uninformed decisionmaker in which the expert's information is certifiable. The first...

This paper studies the set of equilibria that can be achieved by adding general communication systems to Bayesian games in which some information can be certified or, equivalently, in which players’ types are partially verifiable. Certifiability of information is formalized by a set of...

This is a brief survey describing some of the recent progress and open problems in the area of cooperative games with incomplete information. We discuss exchange economies, cooperative Bayesian games with orthogonal coalitions, and issues of cooperation in non-cooperative Bayesian games.

We introduce a class of communication equilibria, which we call self-fulfilling mechanisms, and show that they provide a game-theoretic foundation to rational expectations equilibria. LetEbe an exchange economy with differential information. We associate a strategic market gameΓ(E) withE. We...

Conflicts of interest are the inherent price to pay to benefit from information synergies offered by multiple financial service providers. We focus on conflicts faced by a investment bank's "guru" sell-side analyst, which is torn between the pro-investor research department favoring fair...

We show that in a standard symmetric Cournot duopoly with unknown demand, the optimal information disclosure policy of an informed benevolent planner is to fully inform one of the duopolists and disclose no information to the other one. We discuss possible extensions of the result.
