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...

It has long been recognized that worker wages and productivity are higher in large firms. Moreover, economists have been interested in the efficiency of large firms in R&D enterprises. This paper uses inventor panel data to examine the relationship between inventor productivity and firm size in...

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...

Between 1961 and 1985, the annual domestic patent application count in the U.S. varied within a narrow range of 59,000 and 72,000. Patent applications have risen dramatically in the last decade by 70 percent, reaching 124,000 in 1995. Patents granted have risen commensurately. In this paper, we...

Protection of intellectual property rights (IPRs) serves a dual role in economic development. While it promotes innovation by providing legal protection of inventions, it may retard catch-up and learning by restricting the diffusion of innovations. Does stronger IPR protection in a developing...
