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...

The wage impact of immigration depends crucially on the elasticity of substitution between similarly skilled immigrants and natives and the elasticity of substitution between high school dropouts and graduates. This paper revisits the estimation of these elasticities. The U.S. data indicate that...

In a recent paper, Ottaviano and Peri (2007a) report evidence that immigrant and native workers are not perfect substitutes within narrowly defined skill groups. The resulting complementarities have important policy implications because immigration may then raise the wage of many native-born...

This paper investigates if the ethnic skill differentials introduced into the United States by the inflow of very dissimilar immigrant groups during the Great Migration of 1880-1910 disappeared during the past century. An analysis of the 1910, 1940, and 1980 Censuses and the General Social...

In the 1980s, the wages and employment rates of less-skilled Americans fell relative to those of more-skilled workers. This paper examines the contribution of the continuing inflow of less-skilled immigrants and the increasing importance of imports in the U.S. economy to these trends. Our...

Over 12 million persons migrated to Canada or the United States between 1959 and 1981. Beginning in the mid?1960s, the immigration policies of the two countries began to diverge considerably: the United States stressing family reunification and Canada stressing skills. This paper shows that the...

The postwar period witnessed major changes in U.S. immigration policy and in economic and political conditions in many of the source countries. As a result, the size, origin, and skill composition of immigrant flows changed substantially. This paper uses the Public Use Samples of the five...
