Since the early 1980s, the U.S. economy has experienced a growing wage differential: high-skilled workers have claimed an increasing share of available income, while low-skilled workers have seen an absolute decline in real wages. How and why this disparity has arisen is a matter of ongoing...

There has been little rigorous evaluation of immigration barriers intended to improve domestic terms of employment by shrinking the workforce. We study one such barrier, a policy change that excluded almost half a million Mexican bracero seasonal agricultural workers from the United States....

We propose a mechanism for labor-market polarization based on the nonhomotheticity of demand that we call the income-driven channel. Our mechanism builds on a novel empirical fact: expenditure elasticities and production intensities in low- and high-skill occupations are positively correlated...

The rapid growth in the number of foreign students enrolled in American universities has transformed the higher education system, particularly at the graduate level. Many of these newly minted doctorates remain in the United States after receiving their doctoral degrees, so that the foreign...

1. The initially steep and later decelerating declines of labor mobility with working age are in large part due to the similar but more steeply declining relation between mobility and length of job tenure

This paper examines the impact of a set of nonwage job characteristics on the quit decisions of young and middle-aged men. The empirical analysis shows that young men are less likely to quit "physical" jobs or jobs with bad working conditions but are more likely to quit repetitive jobs. Older...

The process of matching between firms and workers is an important mechanism in determining the distribution of wages. In a labor market characterised by large dispersion of workers' productivity and worker-firm complementarity, high quality firms have strong incentives to screen for the quality...

Between 1999 and 2004 Switzerland opened its border region (BR) to cross-border workers (CBW), who are foreign residents commuting to Switzerland for work. In this paper, we exploit the timing of implementation and the fact that CBW commute almost exclusively to municipalities close to the...
