What is driving the remarkable increase over the last decade in the propensity of patents to cite academic science? Does this trend indicate that stronger knowledge spillovers from academia have helped power the surge in innovative activity in the U.S. in the 1990s? This paper seeks to shed...

This paper documents the increasing importance of software for successful innovation in manufacturing sectors well beyond the traditional definition of electronics and information technology. Using panel data for 229 publicly listed firms from 18 countries across four manufacturing industries...

Recent empirical work has examined the extent to which international trade fosters international spillovers' of technological information. FDI is an alternate, potentially equally important channel for the mediation of such knowledge spillovers. I introduce a framework for measuring...

We view the political process in China as trading off the social benefits of increased trade and foreign direct investment, against the losses incurred by state-owned enterprises due to such liberalization. A model drawing on Grossman and Helpman (1994, 1996) is used to derive an empirically...

This paper investigates changes in the output and productivity of research and development activities in Japanese manufacturing firms over the 1980s and 1990s. Evidence from aggregate patent and R&D statistics and a micro-level analysis of R&D productivity at the firm-level suggest that there...

The existence of strong spillover' effects of private R&D increases the potential social contribution of R&D but may depress the private incentives to undertake it. R&D consortia offer a potentially effective means of internalizing this externality, and a number of prominent economists have...

Over the last decade, generic penetration in the U.S. pharmaceutical market has increased substantially, providing significant gains in consumer surplus. What impact has this rise in generic penetration had on the rate and direction of early stage pharmaceutical innovation? We explore this...

With increasing frequency, generic drug manufacturers in the United States are able to challenge the monopoly status of patent-protected drugs even before their patents expire. The legal foundation for these challenges is found in Paragraph IV of the Hatch-Waxman Act. If successful, these...

One of the alleged benefits of the recent global movement to strengthen intellectual property rights (IPRs) is that such reforms accelerate transfers of technology between countries. Branstetter, Fisman, and Foley examine how technology transfer among U.S. multinational firms changes in response...

This study analyzes the extent of knowledge and technology absorption for firms in Europe and Central Asia (ECA), as well as the factors that influence absorption, using statistical analyses of various data sources, including the World Bank enterprise surveys, patent databases maintained by the...
