This paper studies a closed economy with a continuum of agents and moral hazard. Economic agents in the economy operate a stochastic production technology with capital and labor inputs in which the latter is private information. I characterize efficient allocations of capital, labor, and...

A "folk theorem" originating, among others, in the work of Stiglitz maintains that competitive equilibria area always or "generically" inefficient (unless contracts directly specify consumption levels as in Prescott and Townsend, thus bypassing trading in anonymous markets). This paper...

The literature on Walrasian markets in large economies with adverse selection has used various equilibrium refinements, but has obtained no general incentive efficiency of equilibrium, namely when cross-subsidies are needed for efficiency. We show that the same refined equilibria may also be...

This paper presents an infinite-horizon, discounted dynamic programming model of the endogenous opportunity costs of an agent's effort that is allocated among an endogenous number of principals. An agent allocates effort between evaluating new principals and attending to current principals....
