Artificial intelligence (“AI”)-enabled products are expected to drive economic growth. Training data are important for firms developing AI-enabled products; without training data, firms cannot develop or refine their algorithms. This is particularly the case for AI startups developing new...

Artificial Intelligence (AI) startups use training data as direct inputs in product development.These firms must balance numerous trade-offs between ethical issues and data access without substantive guidance from regulators or existing judicial precedence. We survey these startups to determine...

It is widely held that more productive firms grow faster, thus reallocating resources and raising aggregate productivity. Yet little empirical research identifies the features of the mechanisms affecting this process. This paper develops and tests a general model encompassing several mechanisms...

Recent research shows that much recent rise in wage inequality comes from growing differences between firms, especially sorting of skilled workers to high-paying firms. This paper explores the role of proprietary software in these changes. Using job ad data, we find that proprietary software is...

The diffusion of innovations is supposed to dissipate inventors' rents. Yet in many documented cases, inventors freely shared knowledge with rivals, including in steam engines, iron and steel production and textile machinery. Using a model and case studies, this paper explores why sharing did...

In the past, “non-practicing entities” (NPEs), popularly known as “patent trolls,” have helped small inventors profit from their inventions. Is this true today or, given the unprecedented levels of NPE litigation, do NPEs reduce innovation incentives? Using a survey of defendants and a...

On the heels of a widely reported uptick in egregious patent enforcement, six patent reform bills have been introduced in the last six months. All six bills aim to curb nuisance-value patent litigation, a phenomenon popularly referred to as “patent trolling,” by reducing the cost of...

Pay gaps for women and minorities have persisted after accounting for observable differences. Why? If employers can access applicants' salary histories while bargaining over wages, they can take advantage of past inequities, perpetuating inequality. Recently, a dozen US states have banned...

This chapter documents instances from past centuries where inventors freely shared knowledge of their innovations with other inventors. It is widely believed that such knowledge sharing is a recent development, as in Open Source Software. Our survey shows, instead, that innovators have long...
