In this paper we develop a multi-sector general equilibrium model of firm heterogeneity, worker heterogeneity and labor market frictions. We characterize the distributions of employment, unemployment, wages and income within and between sectors as a function of structural parameters. We find...

We document and discuss the implications of a sharp increase in the regional dispersion of skill premia in China in recent years. This has previously been little noted or discussed. We use three urban household surveys for 1995, 2002, and 2007 and estimate skill premia at provincial and city...

This paper briefly reviews the empirical evidence on labor market segmentation and presents some new results on the similarity of the pattern of segmentation across 66 different countries. The paper goes on to consider how unemployment might be understood in a labor market segmentation...

Although 19th century American labor markets were unencumbered by regulatory legislation, labor market institutions played an active role determining labor market outcomes and the distribution of income. We provide evidence of firm-specific rents in 19th century labor markets: employees in firms...

This paper analyzes a marked change in the evolution of the U.S. wage structure over the past fifteen years: divergent trends in upper-tail (90/50) and lower-tail (50/10) wage inequality. We document that wage inequality in the top half of distribution has displayed an unchecked and rather...

This essay discusses the effect of technical change on wage inequality. I argue that the behavior of wages and returns to schooling indicates that technical change has been skill-biased during the past sixty years. Furthermore, the recent increase in inequality is most likely due to an...

This paper examines educational earnings differentials in Canada in the 1980s and compares changes in differentials to those in the United States. Our major finding is that the college/high school differential increased much less in Canada than in the United States. We also find that within...

Over half of the U.S. population receives health insurance through an employer, with employer premium contributions creating a flat "head tax" per worker, independent of their earnings. This paper develops and calibrates a stylized model of the labor market to explore how this uniquely American...

There is a consensus that there is an earnings premium for licensed workers relative to unlicensed workers. However, little is known about how occupational licensing affects earnings inequality. In this paper, we study dynamic, heterogeneous earnings effects of occupational licensing and draw...
