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...

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...

This paper reconsiders the licensing of a common value innovation to a downstream duopoly, assuming a dual licensing scheme that combines a first-price license auction with royalty contracts for losers. Prior to bidding firms observe imperfect signals of the expected cost reduction; after the...
