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...

In this paper we analyze the impact of foreign-born workers in the fields of Science, Technology, Engineering and Math (STEM) on employment and wages in Canadian geographical areas during the period 1991-2006. Canadian policies select immigrants with a strong emphasis on high educational...

Many U.S. businessmen are vocally in favor of an increase in the number of H-1B visas. Is there systematic evidence that this would positively affect firms' productivity, sales, employment or profits? To address these questions we assemble a unique dataset that matches all labor condition...

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...

Economic debate about the consequences of immigration in the US has largely focused on how influxes of foreign-born labor with little educational attainment have affected similarly-educated native-born workers. Fewer studies analyze the effect of immigration within the market for highly-educated...

This paper explores the relationship between economic openness and income per person using cross-country data. To address endogeneity concerns we extend the instrumental-variables strategy first used by Frankel and Romer (1999). First, we show that bilateral geographic characteristics of...

This paper makes two contributions to the literature on the determinants of international migration flows. First, we compile a new dataset on annual bilateral migration flows covering 15 OECD destination countries and 120 sending countries for the period 1980-2006. We also collect data on...

This paper contains three important contributions to the literature on international migrations. First, it compiles a new dataset on migration flows (and stocks) and on immigration laws for 14 OECD destination countries and 74 sending countries for each year over the period 1980-2005. Second, it...
