It is widely argued that international extension of the patent system hinders innovation and growth in developing countries by restricting access to technological inputs. I re-examine the connection between patents, innovation and development by assessing the extent to which the U.S. patent...

Intellectual property rests on a simple incentive rationale: without imitation barriers, innovators rationally decline to invest. But this blanket proposition is incompatible with markets where innovation proceeds without substantial recourse to intellectual property and imitation is widespread....

The incentive thesis supplies the primary rationale for the patent system: without an exclusionary right, firms will decline to invest in innovations that are subject to expropriation. Empirical inquiry into the incentive thesis’ scope of application has yielded complex results, which are...

The fashion market is an anomaly: innovation is vigorous but original producers are substantially unprotected against imitation, which proliferates under an incomplete property regime consisting of strong trademark protections and weak design protections. We account for this anomaly through a...

It is now widely asserted that legal regimes that enforce contractual and other limitations on labor mobility deter technological innovation. First, recent empirical studies purport to show relationships between bans on enforcing noncompete agreements, increased employee movement, and increased...

This short contribution updates through 2018 the author’s prior empirical study on global innovation trends as indicated by USPTO patenting data during 1965-2015. The principal trends identified previously have largely continued, with the exception of a slight universal decline in annual...
