What is the optimal system of intellectual property rights to encourage innovation? Empirical evidence from economic history can help to inform important policy questions that have been difficult to answer with modern data: 1) Does the existence of strong patent laws encourage innovation? And 2)...

This paper is an exercise in comparative institutional analysis, asking what kinds of arrangements most facilitate innovation. After identifying pervasive market failures in innovation, it explains why those associated with the Nordic model may be particularly conducive to innovation, and...

Recent accounts suggest the development and commercialization of invention has become more "open." Greater division of labor between inventors and innovators can enhance social welfare through gains from trade and greater economies of specialization. Moreover, this extensive reliance upon...

This paper assesses the validity and accuracy of firms' backward patent citations as a measure of knowledge flows from public research by employing a newly constructed dataset that matches patents to survey data at the level of the R&D lab. Using survey-based measures of the dimensions of...

Members of a patent pool agree to use a set of patents as if they were jointly owned by all members and license them as a package to other firms. Regulators favor pools as a means to encourage innovation: Pools are expected to reduce litigation risks for their members and lower license fees and...

The history of innovation in the chemical industry offers many insights for accelerating energy innovation. In this chapter, we begin by laying out the early history of the chemical industry for an overview of the role innovation has played in its development. We then explore three noteworthy...

Economists and policy makers have long recognized that innovators must be able to appropriate a reasonable portion of the social benefits of their innovations if innovation is to be suitably rewarded and encouraged. However, this paper identifies a number of specific fact patterns under which...

The continuations procedure within the U.S. patent system has been criticized for enabling firms to manipulate the patent review process for strategic purposes. Changes during the 1990s in patent procedures affected the incentives of applicants to exploit the continuations process, and...

This paper argues that the ability to keep innovations secret may be a key determinant of patenting. To test this hypothesis, the paper examines a newly-collected data set of more than 7,000 American and British innovations at four world's fairs between 1851 and 1915. Exhibition data show that...

The pace of innovation is related both to the level of investment in innovation and the pool of knowledge from which innovators can draw. Both of these are endogenous: Investments in innovations are affected by the pool of knowledge and the ability of firms to appropriate the returns to their...
