|November 2008||On the Sorting of Physicians across Medical Occupations|
with Pascal Courty: w14502
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 assortative matching takes place; more able physicians join occupations less exposed to moral hazard risk, face more powerful performance incentives, and are more productive. Under-consumption of health services relative to the first best allocation increases with occupational (moral hazard) risk. Occupations with risk above a given threshold are not viable. The model offers an explanation for the persistence of distortions in the mix of health care services offered the differential impact of malpracti...
|November 2006||International Knowledge Flows: Evidence from an Inventor-Firm Matched Data Set|
with Jinyoung Kim, Sangjoon John Lee: w12692
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 use these data to examine the role of research personnel as a pathway for the diffusion of ideas from foreign countries to U.S. innovators. In particular, we find in recent years an increase in the extent that U.S. innovating firms collaborate with or employ researchers with foreign experience. This increase appears to work primarily through an increase in U.S. firms' employment of foreign-residing researchers; the fraction of research-active U.S. residents with foreign research experience appears t...
|July 2005||The Influence of University Research on Industrial Innovation|
with Jinyoung Kim, Sangjoon John Lee: w11447
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 researcher or through some form of collaboration with university researchers. Having an advanced degree is another indicator of an inventor's exposure to university research. We find a steady increase in industry's use of inventors with university research experience over the period 1985-97, economy wide and in the pharmaceutical and semiconductor industries in particular. We interpret this as evidence of growth in the influence of university research on industrial innovation. Moreover, during this period we...
