Microeconomic data on individual firms and employer-employee matches reveal substantial and persistent dispersion in firm size, productivity, and average wage paid and a positive correlation between each pair. To the extent that intrinsic differences in firm productivity explain these facts,...

model developed by Klette and Kortum (2004) and an equilibrium search model of the labor market with job to job flows introduced by Mortensen (2003). In the construction, a continuum of intermediate product and service varieties are produced with labor that serve as inputs in the production of a...

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...

Productivity dispersion across firms is large and persistent, and worker reallocation among firms is an important source of productivity growth. An equilibrium model of growth and firm evolution designed to clarify the role of worker reallocation in the growth process is studied. We show that it...

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...

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...

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. The model is a modified version of the...

In Lentz and Mortensen (2005) we formulate and estimate a market equilibrium model of endogenous growth through product innovation in the spirit of Klette and Kortum (2004). In this paper, we provide a quantitative solution to the planner’s problem in the modeled environment. We find that...

The purpose of this paper is to develop a framework that allows one to distinguish between the extent to which differences in firm productivity are intrinsic and the proposition that higher paying firms employ more able workers. For this purpose, we adapt the equilibrium stochastic model of firm...
