Index Theory: The Law, Promise and Failure of Financial Indices

Financial indices, like the S&P 500 or the Consumer Price Index, have become a ubiquitous feature of our financial markets. One index, the London InterBank Offered Rate (“Libor”), may be the world’s most important number, an interest rate benchmark upon which hundreds of trillions of dollars depend. Yet, almost everyday new revelations emerge that Libor was tampered with during the height of the financial crisis by one or many of the world’s most prominent banks, with billions of dollars potentially misappropriated. This index disruption has attracted tremendous interest from regulators, private litigants, and market observers. Despite their importance, however, financial indices are poorly understood, and almost completely unstudied. In this Article, we explain why and how people use financial indices as well as how they are created. We show human discretion and value judgment to be essential ingredients in even the most “objective” indices. We then develop a taxonomy of financial indices, illustrating how the risks indices can pose, and the solutions applicable to those risks are intimately related to the motivation that drives the index’s creation. We show that the manipulation of indices is unsurprising given the precarious state of intellectual property rights in indices. While many call for prosecuting or regulating the Libor banks, our novel solution is to strengthen property rights for those who create financial indices.

Enterprise Without Entities

Scholars and practicing lawyers alike consider legal entities to be essential. Who can imagine running a large business without using a business organization, such as a corporation or partnership? This Article challenges conventional wisdom by showing that vast enterprises – with millions of customers paying trillions of dollars – often operate without any meaningful use of an entity.This Article introduces the reciprocal exchange, a type of insurance company that operates without any meaningful use of a legal entity. Instead of obtaining their insurance from a common nexus of contract, customers directly insure one another through a web of countless bilateral agreements. While often overlooked or conflated with mutual insurance companies, reciprocal exchanges include some of America’s largest and best known insurance enterprises.This Article explores how it is possible to run an international conglomerate with essentially no recourse to organizational law as it is normally conceived, and then draws out the important implications of these findings. The viability of reciprocal exchanges stands as a powerful foil to the academic consensus that legal entities are somehow essential, while nevertheless validating the underlying logic that led scholars to elevate entities in the first place.
