This paper studies a simple model of experimentation and innovation. Our analysis suggests that patents may improve the allocation of resources by encouraging rapid experimentation and efficient ex post transfer [...]
When firms recruit inventors, they acquire not only the use of their skills but also enhanced access to their stock of ideas. But do hiring firms actually increase their use [...]
We study the extent to which a country's strength of Intellectual Property Rights (IPR) protection mediates knowledge spillovers from Foreign Direct Investment (FDI). Following the opposing views in the IPR [...]
In the decade since Napster, file-sharing has undermined the protection that copyright affords recorded music, reducing recorded music sales. What matters for consumers, however, is not sellers' revenue but the [...]
We study the effects of generic entry on prices and utilization using both event study models that exploit the differential timing of generic entry across drug molecules and cast studies. [...]
While cumulative knowledge production is central to growth, little empirical research investigates how institutions shape whether existing knowledge can be exploited to create new knowledge. This paper assesses the impact [...]
Among the market characteristics, only generic competition is significantly related with price, and only in the random effects model. Generic competition reduces price, as expected, but by well less than [...]
Compulsory licensing allows firms in developing countries to produce foreign-owned inventions without the consent of foreign patent owners. This paper uses an exogenous event of compulsory licensing after World War [...]
This chapter uses historical data on patents and registrations of new plant varieties to examine the effects of the Plant Patent Act on biological innovation. Evidence on a later Act, [...]
Because entrepreneurs’ incentives to innovate depends on the gap between the post innovation rent and the pre-innovation rent—call it the net innovation rent. And typically, what competition does is to [...]
