,786 public corporations, and measures of both patent quality and patent value, we find that, while average invention value rises … with size, average invention quality declines, suggesting, per our model, that the large firm advantage is not due to …

knowledge is an input into internal invention, and thus, more valuable to firms with inventive capability. Using a simple model … of innovation and imitation, we explore how inventive capability affects a firm's R&D investments, and thus whether and … external knowledge as well as the supply of external inventions. In an advance over the literature, we treat firm inventive …

We study the relationships between corporate R&D and three components of public science: knowledge, human capital, and … invention. We identify the relationships through firm-specific exposure to changes in federal agency R\&D budgets that are … established firms, which account for more than three-quarters of business R&D, is affected by scientific knowledge produced by …

An inventor's own knowledge is a key input in the innovation process. This knowledge can be built by interacting with … of our new innovation-led endogenous growth model, in which innovations are produced by heterogeneous research teams of … inventors using inventor knowledge. The evolution of an inventor's knowledge is explained through the lens of a diffusion model …

traditional Western R&D hubs, resulting in two challenges for multinationals: (1) how to transfer knowledge across geographic … distances, and (2) how to facilitate learning when local knowledge sources in given technological areas are inadequate. This … teams - and in particular on teams in locations with insufficiently specialized local knowledge stocks - to facilitate …

At least since Arrow (1962), the effects of appropriability on invention have been well studied, but there has been … terminate or commercialize the invention is driven by the current market value of the invention, as well as the option value of … risks. We find that better appropriability in the sense of more effective patent strength and secrecy has a strong negative …

received over their careers, we highlight the impact of early U.S. patent institutions in providing broad access to economic … opportunity and in encouraging trade in new technological knowledge. Through setting low fees and establishing administrative … procedures for application, the United States deliberately created a patent system that allowed a much wider range, in …

success of the invention. Prize-oriented institutions thus appear to be less systematic and not as market-oriented as patent …Such institutions as patent systems cannot be well understood without an assessment of technological creativity in …. Accordingly, this paper offers an empirical comparison of patents in relation to the award of prizes for technological innovation …

How large are spatial barriers to transferring knowledge? We analyze the international operations of multinational … firms to answer this fundamental question. In our model firms can transfer bits of knowledge to their foreign affiliates in … either embodied (traded intermediates) or disembodied form (direct communication). Knowledge transfer costs interact with the …

The rate of regional growth of new knowledge in the field of nanotechnology, as measured by counts of articles and … stocks of recorded knowledge in all scientific fields, and the extent to which tacit knowledge in all fields flows between … patenting. The data provide further support for the cumulative advantage model of knowledge production, and for ongoing efforts …
