Subsidization and Stabilization: Optimal Employment Policy under Aggregate Uncertainty

Abstract

The authors study an economy where externalities provide an explicit role for intervention and technology shocks generate aggregate uncertainty. In laissez-faire there is too much unemployment. However, the authors show how to support the optimal allocation as a decentralized equilibrium using a self-financing linear employment subsidy. Generally, this subsidy is a function of economic conditions, and they characterize the way in which it varies with the shock. A special case of the authors' results indicates that a simple restriction on technology, homotheticity, implies the optimal subsidy is constant or independent of unemployment.
