Firms and governments spend billions of dollars on R&D every year. To increase social welfare, the results of R&D must be commercialized so that consumers can benefit from improved products and lower prices. One measure of R&D output is patents; however, most patent databases contain no...

We study the causal impact of invalidating marginally valid patents during post-grant opposition at the European Patent Office on affected inventors’ subsequent patenting. We exploit exogenous variation in invalidation by leveraging the participation of a patent’s original examiner in the...

Using a new database of all patents issues in Mexico between 1870 and 1911, this paper explores the impact of the vast wave of technology imports into Mexico during the nineteenth century period of globalization. Historians have established that massive technology imports made possible sustained...

This paper tests a number of hypotheses on the use and effectiveness of patents and trade secrets designed to protect innovation. While previous studies have often considered patents and trade secrets as substitutes for one another, we investigate the complementary role of the two protection...

This paper considers the prospect of a government patent buyout in a model of endogenous growth. To this end, the author modifies a standard quality ladder growth model by incorporating possibility of imitation, and rent protection activities (RPAs) by the innovator. The government finances the...

Based on representative firm-level survey data for the three countries Austria, Germany, and Switzerland, we investigate the effects of regulation, energy taxes, voluntary agreements, and subsidies, on the creation of green product innovations. Our data set allows us to distinguish between the...

This paper quantifies the relationship between private-network file sharing activity and music sales in the BitTorrent era. Using a panel dataset of 2,251 albums' U.S. sales and file sharing downloads on a private network during 2008, I estimate the effect of file sharing on album sales....
