We use a new database, the National Establishment Time Series (NETS), to revisit the debate about the role of small businesses in job creation. Birch (e.g., 1987) argued that small firms are the most important source of job creation in the U.S. economy, but Davis et al. (1996a) argued that this...

Shifts in the incidence of various types of training over the 1980s favored more-educated, more-experienced workers. Coupled with the fact that this training is associated with higher wages, these shifts suggest that training may have contributed to the growth of wage inequality in this period....

The need for school-to-work programs or other means of increasing early job market stability is predicated on the view that the chaotic' nature of youth labor markets in the U.S. is costly because workers drift from one job to another without developing skills, behavior, or other characteristics...

The recent debate over minimum wages raises two questions. First, should policy makers no longer believe that minimum wages entail negative consequences for teenagers? Second, should economists discard the competitive labor market model? Our evidence for teenagers, using matched CPS surveys,...

Theory predicts that minimum wages will reduce employer-provided on-the-job training designed to improve workers' skills on the current job, but may increase the amount of training that workers obtain to qualify for a job. We estimate the effects of minimum wages on the amount of both types of...

In recent decades, the US wage structure has been transformed by a rising college premium, a narrowing gender gap, and increasing persistent and transitory residual wage dispersion. This paper explores the implications of these changes for cross-sectional inequality in hours worked, earnings and...

This paper examines the consequences of initial periods of churning,' floundering about,' or mobility' in the labor market to help assess whether faster transitions to stable employment relationships--such as those envisioned by advocates of school-to-work programs--would be likely to lead to...

Standard search and matching models of equilibrium unemployment, once properly calibrated, can generate only a small amount of frictional wage dispersion, i.e., wage differentials among ex-ante similar workers induced purely by search frictions. We derive this result for a specific measure of...

Using a model with constant relative risk-aversion preferences, endogenous labor supply and partial insurance against idiosyncratic wage risk, we provide an analytical characterization of three welfare effects: (a) the welfare effect of a rise in wage dispersion, (b) the welfare gain from...

This paper studies consumption and labor supply in a model where agents have partial insurance and face risk and initial heterogeneity in wages and preferences. Equilibrium allocations and variances and covariances of wages, hours and consumption are solved for analytically. We prove that all...
