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...

We test whether state malpractice reforms differentially attract physicians whose human capital attributes may predispose them towards higher-than-average malpractice risk and lower quality patient care. Using an exit survey of physicians completing residencies between 1998 and 2017, we estimate...

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 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 describe the construction of a panel data set from the U.S. patent data that contains measures of inventors' life-cycle Ramp;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...
