This paper documents the extent and characteristics of plants and firms in the US that are outside the manufacturing sector according to official government statistics but nonetheless are heavily involved in activities related to the production of manufactured goods. Using new data on...

Cumulative innovation is central to economic growth. Do patent rights facilitate or impede such follow-on innovation? This paper studies the effect of removing patent protection through court invalidation on the subsequent research related to the focal patent, as measured by later citations. We...

Many high technology goods are based on standards that require access to several patents that are owned by different IP holders. We investigate the royalties chosen by IP holders under different market structures. Vertical integration of an IP holder and a downstream producer solves the double...

This paper investigates how the mode of entry into a foreign market can be influenced by the intensity of R&D in an industry and the protection of intellectual property rights (IPR) in a recipient country. It then analyzes the link between the IPR regime and policies that place limits on the...

Using multivariate unit root test methods, this Paper investigates the Purchasing Power Parity (PPP) hypothesis at the sectoral level across six European countries over the last seventeen years. Evidence of mean reversion toward PPP is found for the relative prices of some sectors and countries....

We study the issue of income convergence across countries and regions with a Bayesian model which allows us to use information in an efficient and flexible way. We argue that the very slow convergence rates to a common level of per-capita income found, for example, by Barro and Sala-i-Martin, is...

This paper examines the free-market and socially-optimal outcomes in a dynamic oligopoly model with R&D spillovers. First-best optimal subsidies to R&D are higher when firms play strategically against each other, but lower when they cooperate on R&D (at least with high spillovers) and when they...

We use spatial regression discontinuity analysis to test whether the historical partition of Poland among three empires—Russia, Austria-Hungary, and Prussia—has a persistent effect on political outcomes in contemporary Poland and to examine the channels of this influence. We find that the...

This paper makes three contributions to the growing literature on culture and economics. Using answers to the World Values Survey for a sample of 79 countries over the 1989-2004 period, we first provide evidence of cultural homogenization between countries. Second, we provide a model of...
