The Welfare Economics of Moral Hazard

Author

  • Richard Arnott
  • Joseph Stiglitz

Abstract

This paper shows that, except in certain limiting cases, competitive equilibrium with moral hazard is constrained inefficient. The first section compares the competitive equilibrium and the constrained social optimum in a fairly general model, and identifies types of market failure. Each of the subsequent sections focuses on a particular market failure.
