An Equilibrium Model of Search Unemployment

Journal of Political Economy 1984 92(5), 824-840
This paper develops a simple general equilibrium model with sequential search in which a nondegenerate wage offer distribution is endogenously determined. We use this model to analyze the comparative statics effects of increases in unemployment compensation on the unemployment rate and aggregate welfare taking into account the induced change in the wage offer distribution. Our results differ significantly from the predictions of the standard "partial-partial" model. For example, one can expect a selective increase in unemployment compensation, made available to those who impute a relatively low value to leisure, to decrease the equilibrium rate of unemployment.

General Equilibrium Wage and Price Distributions

Quarterly Journal of Economics 1986 101(4), 687
This paper extends models of search market equilibrium to incorporate general-equilibrium considerations. The model we treat is one with a single product market and a single labor market. An equilibrium distribution of prices and wages is the result of optimal price- and wage-setting behavior by firms in conjunction with optimal search by individuals. We prove the existence of a degenerate equilibrium and of a two-point dispersion equilibrium.
