An exchange economy with asymmetrically  informed agents is considered with an exogenous rule that regulates  the information sharing among agents. For it, the notion of stable  sets à la Von Neumann and Morgenstern is analyzed. Two different  frameworks are taken into account as regards...

The rational expectations equilibrium (REE), as introduced in Radner (1979) in a general equilibrium setting à la Arrow–Debreu–McKenzie, often fails to have desirable properties such as universal existence, incentive compatibility and efficiency. We resolve those problems by providing a new...

The conflict between Pareto optimality and incentive compatibility, that is, the fact that some Pareto optimal (efficient) allocations are not incentive compatible is a fundamental fact in information economics, mechanism design and general equilibrium with asymmetric information. This important...
