Internet-based educational resources are proliferating rapidly. One concern associated with these (potentially transformative) technological changes is that they will be disequalizing—as many technologies of the last several decades have been—creating superstar teachers and a winner-take-all...

Administrative data from a large and diverse community college are used to examine if underrepresented minority students benefit from taking courses with underrepresented minority instructors. To identify racial interactions we estimate models that include both student and classroom fixed...

One long-standing hypothesis about science and engineering labor markets is that the supply of highly skilled workers is likely to be inelastic in the short run. We consider the market for computer scientists and electrical engineers (IT workers) and the evolution of wages and employment through...

We study the scale and selectivity of foreign-born PhD students in science and engineering. We focus on students from China, India, Korea, and Taiwan, which together account for most roughly one-third of science and engineering PhD students in the United States. The selectivity of these students...

We develop a framework where mismatch between vacancies and job seekers across sectors translates into higher unemployment by lowering the aggregate job-finding rate. We use this framework to measure the contribution of mismatch to the recent rise in U.S. unemployment by exploiting two sources...
