Employment in STEM occupations suffered smaller peak-to-trough percentage declines than non-STEM occupations during the Great Recession and COVID-19 recession, suggesting a relative resiliency of STEM employment. We exploit the sudden peak-to-trough declines in STEM and non-STEM employment...

We describe the construction of a panel data set from the U.S. patent data that contains measures of inventors' life-cycle R&D productivity--patents and patent citations. We match the data set to information on the U.S. pharmaceutical and semiconductor firms for whom they work. In this paper we...

We use U.S. patent records to examine the role of research personnel as a pathway for the diffusion of ideas from university to industry. Appearing on a patent assigned to a university is evidence that an inventor has been exposed to university research, either directly as a university...

We use the labor market for doctorates in the biomedical sciences, where career dislocation is common, as a case study of skill-task mismatch and its consequences. Using longitudinal, worker-level data on biomedical doctorates, we investigate mismatch as an explanation for the negative pecuniary...

We model the sorting of medical students across medical occupations and identify a mechanism that explains the possibility of differential productivity across occupations. The model combines moral hazard and matching of physicians and occupations with pre-matching investments. In equilibrium...
