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...

This paper provides a general overview of the literature on the core of an exchange economy with asymetric information. Incentive compatibility is emphasized in studying core concepts at the ex ante and the interim stage.The analysis includes issues of non emptiness of the core as wellas core...

A mechanism is posterior efficient in a differential information economy if at every outcome selected by the mechanism, the agents' expected utilities given this outcome cannot be Pareto improved by any feasible mechanism (in the revised economy). We show that a non-revealing (resp. completely...

A mistake in “Five legitimate definitions of correlated equilibrium in games with incomplete information” motivates a re-examination of some extensions of the solution concept that Aumann introduced.

In a differential information economy with quasi-linear utilities, monetary transfers facilitate the fulfillment of incentive compatibility constraints: the associated ex ante core is generically non-empty. However, we exhibit a wellbehaved exchange economy in which this core is empty, even if...
