Nonexistence of constrained Efficient Equilibria when Markets are Incomplete

Author

Abstract

We consider economies with incomplete markets, production, and a given distribution of initial endowments. The main purpose of the paper to present a robust example of an econmy with only one firm and one good per state in which no production dicision entails a constrained efficient outcome. In particular, the unique Dréze equilibrium is dominated by every other production decision.
