The global dynamics of an equilibrium model of aggregate unemployment that focuses on the job/worker matching process is studied for the case of increasing returns to scale in production and constant returns to scale in the matching process. In anticipation of a particular solution to the wage...

The article structually estimates an on-the-job search model of job separations. Given each employer pays observably equivalent workers the same but wages are dispersed across employers, an employer's separation flow is the sum of an exogenous outflow unrelated to the wage and a job-to-job flow...

What can one infer about labor market flows from matched employer- employee panel data? The purpose of this paper is to sketch possible answers to this question. A general but simple labor market equilibrium model of hire and separation flows is developed in the paper. The model embodies the...

Productivity differences across firms are large and persistent, but the evidence for worker reallocation as an important source of aggregate productivity growth is mixed. The purpose of this paper is to estimate the structure of an equilibrium model of growth through innovation designed to...
