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...

This study analyzes information production and trading behavior of banks with lending relationships. We combine trade-by-trade supervisory data and credit-registry data to examine banks' proprietary trading in borrower stocks around a large number of corporate events. We find that relationship...

We develop a model of the joint capital structure decisions of banks and their borrowers. Strikingly high bank leverage emerges naturally from the interplay between two sets of forces. First, seniority and diversification reduce bank asset volatility by an order of magnitude relative to that of...

The current crisis with its on-going banking sector problems has brought to the fore various cases of financial fraud and banking scandals that have additionally undermined the already low confidence in the sector. This has raised concerns about structural flaws in the way banks operate and are...

We develop a model of the joint capital structure decisions of banks and their borrowers. Strikingly high bank leverage emerges naturally from the interplay between two sets of forces. First, seniority and diversification reduce bank asset volatility by an order of magnitude relative to that of...

We investigate the leverage of hedge funds in the time series and cross section. Hedge fund leverage is counter-cyclical to the leverage of listed financial intermediaries and decreases prior to the start of the financial crisis in mid-2007. Hedge fund leverage is lowest in early 2009 when the...

This study investigates the associations among bank risk-taking, ownership concentration, and the recently proposed standard for capital stability (Basel III). Consistent with theory, the evidence shows that a rise in ownership concentration by one standard deviation increases the extent of...

This paper reviews the research on the $6.65trillion dollar Sovereign Wealth Funds (SWF). The literature, which has only appeared in the last few years, focuses for the most part on the investment behavior of SWFs, especially in light of calls for the regulation of these financial entities. The...

This paper studies the determinants of global liquidity using data on cross-border bank flows, with a longer time series and broader country sample than previous studies. We define global liquidity as non-price determinants of cross-border credit supply, consistent with its meaning as the...

In this paper we study systemic risk for the US and Europe. We show that banks’ exposures to common risk factors are crucial for systemic risk. We come to this conclusion by first showing that relations between US and European banks are smaller than within each region. We then show that...
