This essay provides a survey of various models that use search theory to analyze labor markets. By search theory, we mean a framework in which trading frictions are modeled explicitly. Search models generate unemployment as an equilibrium outcome, and also allow us to discuss various ways in...

We develop a simple model featuring search frictions and a nondegenerate labor supply decision along the extensive margin. The model is a standard version of the neoclassical growth model with indivisible labor with idiosyncratic shocks and frictions characterized by employment loss and...

Commonly used frictional models of the labor market imply that changes in frictions have large effects on steady state employment and unemployment. We use a model that features both frictions and an operative labor supply margin to examine the robustness of this feature to the inclusion of a...
