Card's (1990) study of the Mariel supply shock remains an important cornerstone of both the literature that measures the labor market impact of immigration, and of the "stylized fact" that immigration might not have much impact on the wage of workers in a receiving country. My recent reappraisal...

Cardʼs (1990) study of the Mariel supply shock is an important contribution to the literature that measures the labor market impact of immigration. My recent reappraisal (Borjas, 2015) revealed that even the most cursory reexamination implied that the wage of low-skill (non-Hispanic) working...

This paper brings a new perspective to the analysis of the Mariel supply shock, revisiting the question armed with the accumulated insights from the literature on the economic impact of immigration. A crucial lesson from that literature is that any credible attempt to measure the wage impact...

To study the short-run and long-run implications on wage inequality, we introduce directed technical change into a Ricardian model of offshoring. A unique final good is produced by combining a skilled and an unskilled product, each produced from a continuum of intermediates (tasks). Some of...

This paper investigates the impact of unskilled workers' earnings on crime. Following the literature on wage inequality and skill-biased technological change, we employ CPS data to create state-year as well as state-year-and (broad) industry specific measures of skill-biased technological...

Many workers with low levels of educational attainment immigrated to the United States in recent decades. Large inflows of less-educated immigrants would reduce wages paid to comparably-educated native-born workers if the two groups compete for similar jobs. In a simple model exploiting...

Wages for more- and less-educated workers have followed strikingly different paths in the U.S. and Canada. During the 1980's and 1990's, the ratio of earnings of university graduates to high school graduates increased sharply in the U.S. but fell slightly in Canada. Katz and Murphy (1992) found...

This paper studies the effect of the change in occupational structure on wages for low skilled men. We develop a model of occupational choice in which workers have multi-dimensional skills that are exploited differently across different occupations. We allow for a rich specification of...

We study how international trade affects manufacturing employment and the relative wage of unskilled workers when goods and services are traded with different intensities. Manufacturing trade reduces manufacturing prices worldwide, which reduces manufacturing employment if manufactures and...
