We survey the economic literature, both theoretical and empirical, on the choice of intellectual property protection by firms. Our focus is on the tradeoffs between using patents and disclosing versus the use of secrecy, although we also look briefly at the use of other means of formal...

Recent technological changes may have altered the balance between technology and copyright law for digital products. While file-sharing has reduced revenue, other technological changes have reduced the costs of bringing creative works to market. As a result, we don't know whether the effective...

This article exploits a differential increase in copyright under the UK Copyright Act of 1814 - in favor of books by dead authors – to examine the influence of longer copyrights on price. Difference-in-differences analyses, which compare changes in the price of books by dead and living...

Our analysis seeks to understand the impact of changing allocations of property rights on investment in new firms. We focus on the Cartoon Network, et al. v. Cablevision decision in the U.S., which narrowed the protection enjoyed by content creators (e.g., movie studios) and gave greater rights...

Copyrights for books, news, and other types of media are a critical mechanism to encourage creativity and innovation. Yet economic analyses continue to be rare, partly due to a lack of experimental variation in modern copyright laws. This paper exploits a change in copyright laws as a result of...

Does the lack of international copyrights benefit or harm developing countries? I examine the effects of U.S. copyright piracy during a period when the U.S. was itself a developing country. U.S. statutes since 1790 protected the copyrights of American citizens, but until 1891 deemed the works of...

Intellectual property treaties have two main types of provisions: national treatment of foreign inventors, and harmonization of protections. I address the positive question of when countries would want to treat foreign inventors the same as domestic inventors, and how their incentive to do so...

New information technology has reduced marginal production and distribution costs of information goods to negligible levels and promises to revolutionize many industries. Unpaid copies of digital products can be as good as paid first-generation copies, and their availability can undermine the...

Much debate exists around the impact that illegal file sharing may have on the creative industries. Similarly, opinions differ regarding whether the producers of artistic works should be forced to accept any weakening of intellectual property rights resulting from illegal file sharing, or if...

Despite the concern that student plagiarism has become increasingly common, there is relatively little objective data on the prevalence or determinants of this illicit behavior. This study presents the results of a natural field experiment designed to address these questions. Over 1,200 papers...
