This paper estimates the effects of immigration on wages of native workers at the national U.S. level. Following Borjas (2003) we focus on national labor markets for workers of different skills and we enrich his methodology and refine previous estimates. We emphasize that a production function...

This paper asks the following important question: what was the effect of surging immigration on average and individual wages of U.S.-born workers during the period 1990-2004? Building on section VII of Borjas (2003) we emphasize the need for a general equilibrium approach to analyze this...

In this paper we study the impact of immigration to the United States on the vote for the Republican Party by analyzing county-level data on election outcomes between 1990 and 2010. Our main contribution is to separate the effect of high-skilled and low-skilled immigrants, by exploiting the...

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 are perfectly substitutable in production. In a simple model...

How many "American jobs" have U.S.-born workers lost due to immigration and offshoring? Or, alternatively, is it possible that immigration and offshoring, by promoting cost-savings and enhanced efficiency in firms, have spurred the creation of jobs for U.S. natives? We consider a multi-sector...

The H-1B program allows skilled foreign-born individuals to work in the United States. The annual quota on new H-1B issuances fell from 195,000 to 65,000 for employees of most firms in fiscal year 2004. This cap did not apply to new employees of colleges, universities, and non-profit research...

Does a high regional concentration of immigrants of the same ethnicity affect immigrant children's acquisition of host-country language skills and educational attainment? We exploit the exogenous placement of guest workers from five ethnicities across German regions during the 1960s and 1970s in...
