If the allocation of a differential information economy are defined as incentive compatible state - contingent lotteries over consumption goods, competitive equilibrium allocations exist and belong to the (ex ante incentive) core. Furthermore, any competitive equilibrium allocation can be viewed...

Maximizing the probability of bypassing an aspiration level, and taking increasing risks to recover previous losses are well-documented behavioral tendencies. They are compatible with individual utility functions that are S-shaped, as suggested in Prospect Theory (Kahneman and Tversky 1979). We...

Successful individuals were frequently found to be overly optimistic. These finding are puzzling, as one could expect that realists would perform best in the long run. We show, however, that in a large class of strategic interactions of either cooperation or competition, the equilibrium payoffs...

The paper discusses several topics such Nash equilibria, repeated games. It also discusses applications to market games, regulation and R&D 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.
