We measure the extent to which skilled immigrants increase innovation in the United States by exploring individual patenting behavior as well as state-level determinants of patenting. The 2003 National Survey of College Graduates shows that immigrants patent at double the native rate, and that...

Using the 2003 National Survey of College Graduates, I examine how immigrants perform relative to natives in activities likely to increase U.S. productivity, according to the type of visa on which they first entered the United States. Immigrants who first entered on a student/trainee visa or a...

This paper describes the theoretical underpinnings and provides empirical evidence for a model that predicts a positive impact of immigration on entrepreneurial activity. Immigrants, we hypothesize, facilitate innovation and entrepreneurship by being willing and able to invest in new skills. At...

Using a state panel based on census data from 1940-2010, I examine the impact of immigration on the high school completion of natives in the United States. Immigrant children could compete for schooling resources with native children, lowering the return to native education and discouraging...

An ongoing debate is whether the U.S. should continue its family-based admission system, which favors visas for family members of U.S. citizens and residents, or adopt a more skills-based system, replacing family visas with employment-based visas. In many ways this is a false dichotomy:...

Historical, longitudinal data are used to track the earnings of cohorts of immigrant and U.S.-born women over time. The longitudinal data circumvent potential cohort biases that afflict cross-sectional analyses of immigrant earnings growth and biases due to immigrant emigration and other issues...

The labor market "quality" of immigrants is a subject of debate among immigration researchers, and a major public policy concern. However, traditional methods of measuring human capital are particularly difficult to apply to recently arrived immigrants. Many factors that have a negative effect...

I use the 1993 and 2003 National Surveys of College Graduates to examine the higher exit rate of women compared to men from science and engineering relative to other fields. I find that the higher relative exit rate is driven by engineering rather than science, and show that 60% of the gap can...

We investigate women's underrepresentation among holders of commercialized patents: only 5.5% of holders of such patents are female. Using the National Survey of College Graduates 2003, we find only 7% of the gap in patenting rates is accounted for by women's lower probability of holding any...
