Cross-subsidies are often considered the principal mechanism through which hospitals provide unprofitable care. Yet, hospitals' reliance on and extent of cross-subsidization are difficult to establish. We exploit entry by cardiac specialty hospitals as an exogenous shock to incumbent hospitals'...

Prior studies suggest that, with elastically supplied inputs, free entry may lead to an inefficiently high number of firms in equilibrium. Under input scarcity, however, the welfare loss from free entry is reduced. Further, free entry may increase use of high-quality inputs, as oligopolistic...

Due to the limited availability of firm-level compensation data, there is little empirical evidence on the impact of compensation plans on personal productivity. We study an international law firm that moves from high-powered individual incentives towards incentives for "leadership" activities...

We establish an important role for the firm by studying capital reallocation decisions of mutual fund firms. At least 30% of the value mutual fund managers add can be attributed to the firm's role in efficiently allocating capital amongst its mutual fund managers. We find no evidence of a...

We examine the impact of outside purchase contracts on firm risk and firm capital structure. We find that firms with more outside purchase contracts have less risky cash flows. Despite these less risky cash flows, firms with these contracts also have less financial leverage especially when they...

What are the individual rewards to working in teams? This question extends across many production settings but is of long-standing interest in science and innovation, where the "Matthew Effect" suggests that eminent team members garner credit for great works at the expense of less eminent team...

This paper documents the extent and characteristics of plants and firms in the US that are outside the manufacturing sector according to official government statistics but nonetheless are heavily involved in activities related to the production of manufactured goods. Using new data on...

We report a puzzling pair of facts concerning the organization of science. The concentration of research output is declining at the department level but increasing at the individual level. For example, in evolutionary biology, over the period 1980 to 2000, the fraction of citation-weighted...

Union membership displayed a ∩-shaped pattern over the 20th century, while the distribution of income sketched a ∪. A model of unions is developed to analyze these phenomena. There is a distribution of firms in the economy. Firms hire capital, plus skilled and unskilled labor. Unionization...
