Gerald Marschke examined university and industrial patents and found evidence of two trends that suggest a growing link between university research and industrial innovation. First, the flow of university researchers to private sector firms is growing. Second, industrial innovators are using...

It has long been recognized that worker wages and possibly productivity are higher in large firms. Moreover, at least since Schumpeter (1942) economists have been interested in the relative efficiency of large firms in the research and development enterprise. This paper uses longitudinal...

We present a model of how organizations manage performance measures when gaming is revealed over time. The incentive designer does not know when it selects a performance measure whether it will communicate the right behavior. Only over time does the principal find out the agent's responses and...

Using U.S. patent records in nanotechnoloy, we study the relationship between inventor mobility among firms and knowledge diffusion. We find evidence consistent with a story that, in one important nanotechnology subfield, when inventors move among firms they spread knowledge. In particular, we...

Using U.S. patent records in nanotechnoloy, we study the impact of university research on industry innovations with the premise that knowledge is diffused from universities to industry via personnel with university research experience. Appearing on a patent assigned to a university is evidence...

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 ineventor has been exposed to university research, either directly as a university...

We decompose the recent patent increase into components representing (1) an increase in resources made available to research and development, (2) an across-the-board rise in the patent yield of an R&D dollar, and (3) changes in the patent yield in individual industries. Two high tech fields,...

It has long been recognized that worker wages and possibly productivity are higher in large firms. Moreover, at least since Schumpeter (1942) economists have been interested in the relative efficiency of large firms in the research and development enterprise. This paper uses longitudinal...

Many studies have shown that small firms generate more patents per R&D dollar than large firms. Does this mean that small firms are more efficient innovators than large firms? In this paper we exploit a unique data set to reexamine the firm size-innovation relationship. Because firm-reported R&D...
