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...

The Nash program is an important research agenda initiated in Nash (Econometrica 21:128-140, 1953) in order to bridge the gap between the noncooperative and cooperative counterparts of game theory. The program is thus turning sixty-seven years old, but I will argue it is not ready for...

We consider the class of two-person non-zero-sum infinitely repeated games with incomplete information where Nash equilibria have been characterized, namely games with lack of information on one side and games with private values. We show that in these models, every Nash equilibrium payoff can...

In a Bayesian game G, the players first receive private information on the state of nature and then simultaneously choose an action. We assume that the vector of actions a generates a signal g(a). A mechanism for G is a mapping [ mu ] from the set of states of nature S to the product sert of...
