In McLean and Postlewaite (2001), we analyzed a general equilibrium model with asymetrically informed agents. We presented a notion of informational size and showed (among other things) that when agents' information as a whole resolved nearly all the uncertainty, the conflict between incentive...

Numerous recent studies on macroeconomic policy -- including monetary policy and tax policy -- have incorporated private information in their models of the economy. In such models, characterization of Pareto-optimal allocations is an important step of analysis. In this article, we study Pareto...

This book analyzes the existence of equilibria in economies having a measured space of agents and a continuum of agents and commodities. Excessive homogeneity with respect to agent productivity leads to instability and non-uniqueness of a given stationary state and the indeterminacy of the...

Policy-makers must sometimes choose between an alternative which has somewhat lower expected value for each person, but which will substantially improve the outcomes of the worst off, or an alternative which has somewhat higher expected value for each person, but which will leave those who end...
