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 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 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 develop and test a model of the patenting and R&D decisions of an innovating firm whose researcher-employees sometime quit to join or start a rival. In our model, the innovating firm patents to protect itself from its workers. We show theoretically that the risk of a scientist's departure...

This paper studies the provision of incentives in the large federal bureaucracy created under the Job Training Partnership Act of 1982. We find that bureaucrats respond to these incentives by maximizing their private rewards, possibly at the expense of social welfare. We argue that the inability...
