Liability laws designed to compensate for harms caused by defective products may also affect innovation. We examine this issue by exploiting a major quasi-exogenous increase in liability risk faced by US suppliers of polymers used to manufacture medical implants. Difference-in-differences...

We study the impact of consumers' risk perception on firm innovation. Our analysis exploits a major surge in the perceived risk of radiation diagnostic devices, following extensive media coverage of a set of over-radiation accidents involving CT scanners in late 2009. Difference-in-differences...

We examine the relationship between product liability litigation and innovation by systematically combining data on product liability lawsuits with data on new product introductions in a panel dataset of leading medical device firms. We first document a decline in the propensity to introduce new...

Are laboratory safety practices a tax on scientific productivity? We examine this question by exploiting the substantial increase in safety regulations at the University of California following the shocking death of a research assistant in 2008. Difference-in-differences analyses show that...

Current academic and policy debates focus on the impact of tort reforms on physicians' behavior and medical costs. This paper examines whether these reforms also affect incentives to develop new technologies. We find that, on average, laws that limit the liability exposure of healthcare...

Copyright infringement may result from frictions preventing legal consumption, but may also reveal demand. Motivated by this fact, we run a field experiment in which we contact firms that are caught infringing on expensive digital images. Emails to all firms include a link to the licensing page...

Effective dispute resolution is important for reducing private and social costs. We study how resolution responds to changes in price and communication using a new, extensive dataset of copyright infringement incidences by firms. The data cover two field experiments run by a large...

We study the causal impact of patent invalidation on subsequent innovation and exit by the patent holder. The analysis is based on patent litigation at the U.S. Court of Appeals for the Federal Circuit, and exploits the random allocation of judges to control for endogeneity of the judicial...

Cumulative innovation is central to economic growth. Do patent rights facilitate or impede follow-on innovation? We study the causal effect of removing patent rights by court invalidation on subsequent research related to the focal patent, as measured by later citations. We exploit random...

Patents are a useful but imperfect reward for innovation. In sectors like pharmaceuticals, where monopoly distortions seem particularly severe, there is growing international political pressure to identify alternatives to patents that could lower prices. Innovation prizes and other non-patent...
