Berkshire Hathaway has realized a Sharpe ratio of 0.76, higher than any other stock or mutual fund with a history of more than 30 years, and Berkshire has a significant alpha to traditional risk factors. However, we find that the alpha becomes insignificant when controlling for exposures to...

This paper provides empirical evidence of the impact of hedge funds on asset markets. We construct a simple measure of the aggregate illiquidity of hedge fund portfolios, and show that it has strong in- and out-of-sample forecasting power for 72 portfolios of international equities, corporate...

We develop a model of financially constrained arbitrage, and use it to study the dynamics of arbitrage capital, liquidity, and asset prices. Arbitrageurs exploit price discrepancies between assets traded in segmented markets, and in doing so provide liquidity to investors. A collateral...

The eurozone has a single short-term nominal interest rate, but monetary policy conditions measured by either real short-term interest rates or Taylor rule residuals varied substantially across countries in the period from 2003-2010. We use this cross-country variation in the (local) tightness...

This paper provides evidence for a causal effect of equity prices on corporate investment and employment. We use fire sales by distressed equity funds during the 2007-2009 financial crisis to identify substantial exogenous underpricing. Firms whose stocks are most underpriced have considerably...

The early stage of the recent financial crisis was marked by large value losses for bank stocks. This paper identifies the equity funds most affected by this valuation shock and examines its consequences for the non-financial stocks owned by the respective funds. We find that (i) ownership links...

Employing data from a new secondary market for hedge funds, this paper documents the existence of a closed-hedge fund premium, analogous to the closed-end mutual fund premium which has been extensively studied in the literature. Over the past decade, the two premia comove with one another at...

This paper provides evidence on the use of stochastic discount factors in the evaluation of portfolio performance. First, we discuss evaluation in this setting, and relate it to traditional mean-variance analysis. We then use Monte Carlo experiments to examine the small sample properties of...

We use a comprehensive dataset of Funds-of-Hedge-Funds (FoFs) to investigate performance, risk and capital formation in the hedge fund industry over the past ten years. We confirm the finding of high systematic risk exposures in FoF returns. We divide up the past ten years into three distinct...

We analyse the equilibrium consequences of performance-based contracts for fund managers. Managerial remuneration is tied to a fund's absolute performance and its performance relative to rival funds. Investors choose whether or not to delegate their investment to better-informed fund managers;...
