This article analyzes the manifold situations in which the efficient-market hypothesis (EMH) has influenced—or has failed to influence—federal securities regulation and state corporate law, and the prospective roles for the EMH in these contexts. In federal securities regulation, the EMH has...

We examine the pricing of financial crash insurance during the 2007-2009 financial crisis in U.S. option markets. A large amount of aggregate tail risk is missing from the price of financial sector crash insurance during the financial crisis. The difference in costs of out-of-the-money put...

Financial regulation today is largely framed by traditional business categories. The financial markets, however, have begun to bypass those categories, principally over the last thirty years. Chief among the changes has been convergence in the products and services offered by traditional...

Many observers have argued that credit default swaps contributed significantly to the credit crisis. Of particular concern to these observers are that credit default swaps trade in the largely unregulated over-the-counter market as bilateral contracts involving counterparty risk and that they...

This paper presents a flexible, lattice-based structural credit risk model that uses equity market information and a detailed depiction of a financial institution’s liability structure to analyze default risk. The model is applied to examine the term structure of default probabilities for...

In the 1990s, companies collected billions in premiums from peculiarly structured put options written on their own stock while almost all of these puts expired worthless. Buyers of these options, primarily �nancial intermediaries, lost money as a result. Although these losses might seem...

We discuss the literature on the shift from stakeholder to shareholder finance behind the Great Financial Crisis (GFC). Traditional banks generally maximized stakeholder value (STV). But before the GFC also many of them started maximizing shareholder value (SHV). Moving from STV to SHV often...

We extend our prior work on how both supply (including the emergence of OTC equity derivatives and growth in share lending) and demand (including the growth of hedge funds) factors now facilitate the large-scale, low-cost decoupling of shareholder voting rights from shareholder economic...
