Courts have articulated a number of legal tests to distinguish corporate transactions that have a legitimate business or economic purpose from those carried out largely, if not solely, for favorable tax treatment. We outline an approach to analyzing the economic substance of corporate...

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...

This paper builds a theory of informal contract enforcement in social networks. In our model, relationships between individuals generate social collateral that can be used to control moral hazard when agents interact in a borrowing relationship. We define trust between two agents as the maximum...

Economists seeking to improve the efficiency of health care delivery frequently emphasize two issues: the fragmented structure of physician practices and poorly designed physician incentives.

The large inflow of investment capital to commodity futures markets in the last decade has generated a heated debate about whether financialization distorts commodity prices. Rather than focusing on the opposing views concerning whether investment flows either did or did not cause a price...

The share of U.S. corn production used to produce ethanol increased from 12.4% in the 2004/05 crop year to over 38.5% in the 2010/11 crop year, and remained at that high level in 2011/12. Even after accounting for return of by-products to the feed market, this is a large and persistent new...

Public school choice programs give households a free choice of public school and provide schools incentives to compete for students. Proponents of these programs argue that by the usual market logic, choice and competition will improve the quality of the education that schools provide. Critics...

In this paper, we provide a new framework for analyzing corruption in public bureaucracies. The standard way to model corruption is as an example of moral hazard, which then leads to a focus on better monitoring and stricter penalties with the eradication of corruption as the final goal. We...
