The rising importance of Information Technology (IT) occupations in the U.S. economy has been accompanied by an expansion in the representation of high-skill foreign-born IT workers. To illustrate, the share of foreign born in IT occupations increased from about 15.5% to about 31.5% between 1993...

We study the impacts on remittances of offering migrants temporary discounts on remittance transaction fees. We randomly assigned migrants from El Salvador and Guatemala 10-week remittance transaction fee discounts, and assess impacts using administrative transaction data and a post-experiment...

We use data from the NSF Survey of Earned Doctorates to examine the post-degree location choices of foreign-born students receiving PhDs from US universities in science and engineering. Over the period 1960 to 2008, 77% of foreign-born S&E PhDs state that they plan to stay in the United States....

According to national accounts data, value added per worker is much higher in the non-agricultural sector than in agriculture in the typical country, and particularly so in developing countries.

This paper explores the link between mobility and the presence of international research networks. Data come from the GlobSci survey of authors of articles published in 2009 in four fields of science working in sixteen countries. Summary evidence suggests that migration plays an important role...

The onset of World War I spurred the "Great Migration" of African Americans from the U.S. South, arguably the most important internal migration in U.S. history. We create a new panel dataset of more than 5,000 men matched from the 1910 to 1930 census manuscripts to address three interconnected...

While immigration policies are typically national, the effects of international migrants are often more easily identified on local economies. The reason is that their...

Historical accounts suggest that Jewish émigrés from Nazi Germany revolutionized U.S. science. To analyze the émigrés' effects on chemical innovation in the U.S. we compare changes in patenting by U.S. inventors in research fields of émigrés with fields of other German chemists. Patenting...

Using longitudinal data on the universe of workers in Denmark during the period 1991-2008 we track the labor market outcomes of low skilled natives in response to an exogenous inflow of low skilled immigrants. We innovate on previous identification strategies by considering immigrants...
