Dispersion in labor and factor productivity across firms is large and persistent, large flows of workers move across firms, and worker reallocation is an important source of productivity growth. The purpose of the paper is to provide a formal explanation for these observations that clarifies the...

This paper estimates a job search model with savings and determines optimal unemployment benefit policy for the estimated model. For observed and unobserved worker characteristics, the estimation strategy relates observed unemployment spell durations to the model implied unemployment hazard...

Productivity dispersion across firms is large and persistent, and worker reallocation among firms is an important source of productivity growth. The purpose of the paper is to estimate the structure of an equilibrium model of growth through innovation that explains these facts. The model is a...

Estimates of the structural parameters of a job separation model derived from the theory of on-the-job search are reported in this paper. Given that each employer pays the same wage to observably equivalent workers but wages are dispersed across employers, the theory implies that an employer's...

In this paper we study a risk averse worker's optimal savings and job-search behavior as she moves back and forth between employment and unemployment. Recent empirical findings suggest a negative association between a risk averse worker's search effort and wealth. We show that additively...
