How much of the rapid growth in labor productivity in nineteenth century cotton weaving arose from capital-labor substitution and how much from technical change? Using an engineering production function and detailed information on inventions, I find that factor substitution accounts for little...

This report examines changes in the patenting behavior of the software industry since the 1990s. It finds that most software firms still do not patent, most software patents are obtained by a few large firms in the software industry or in other industries, and the risk of litigation from...

Firms reduce the marginal cost of communicating technical knowledge by “formalizing” it in standards, dominant designs or other ways. But this only pays when new technology is sufficiently developed. In a simple model with endogenous communication costs, two equilibria emerge. With...

Did nineteenth century technology reduce demand for skilled workers in contrast to modern technology? I obtain direct evidence on human capital investments and the returns to skill by using micro-data on individual weavers and an engineering production function. Weavers learned substantially on...

How should the economic performance of property systems be evaluated? Benefit-cost analysis is widely used to evaluate non-market based regulation when prices are not available. Market prices provide better information for property systems, but market prices are not necessarily socially optimal...

In the last several years, business leaders, policymakers, and inventors have complained to the media and to Congress that today’s patent system stifles innovation instead of fostering it. But like the infamous patent on the peanut butter and jelly sandwich, much of the cited evidence about...
