Attainment of rational expectations equilibria in asset markets calls for the price system to disseminate traders' private information to others. It is known that markets populated by asymmetrically-informed profit-motivated human traders can converge to rational expectations equilibria. This...

Information aggregation is a key economic function of markets. Evidence on limitations of human cognitive abilities have led some to doubt the usefulness and relevance of rational expectations equilibria in modeling information aggregation. We report results of a computational experiment with...

We analyze the stability of a discrete-time dynamic model with an IS-LM structure. We assume that the Aggregate Supply function is of Lucas type, and the monetary policy rule is of Friedman type. The mechanism of expectations formation is assumed to be of adaptive type (Friedman-Cagan). In its...

This article demonstrates that in the standard two-period lived overlapping-generations model with rational expectations, price-taking behavior of agents on the capital market is implausible. We show that market power reduces agents' savings relative to the price-taker benchmark such that less...

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...

Firms with private information about the outcomes of production under uncertainty may face capital (liquidity) constraints that prevent them from attaining efficient levels of investment in a world with costly and/or imperfect monitoring. As an alternative, we examine the efficiency of a simple...

Economies with asymmetric information are encompassed by an extension of the model of general competitive equilibrium that does not require an explicit modeling of private information. Sellers have discretion over deliveries on contracts; this is in common with economies with default, incomplete...
