In perfectly competitive economies under uncertainty, there is a well-known equivalence between a formulation with contingent goods and a formulation with state-specific securities followed by spot markets for goods. In this paper, I examine whether this equivalence carries over in a particular...

This paper introduces E-capacities as a representation of beliefs which incorporates objective information about the probability of events. It can be shown that the Choquet integral of an E-capacity is the Ellsberg representation. The paper further explores properties of this representation of...

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.

This paper describes the historical evolution of the analysis of some aspects of the strategic use of information. The use of mixed strategies aims to create uncertainty on the move to be played or on the private information of the players. In a repeated game framework, strategic behavior when...
