We develop a new approach for evaluating performance across hedge funds. Our approach allows for performance comparisons between models that are misspecified – a common feature given the numerous factors that drive hedge fund returns. The empirical results show that the standard models used in...

This paper studies the implications of opacity in fi nancial markets for investor behavior, asset prices, and welfare. Transparent funds (e.g. mutual funds) and opaque funds (e.g. hedge funds) trade transparent assets (e.g. plain-vanilla products) and opaque assets (e.g. structured products)....

We find evidence that hedge funds significantly manipulate stock prices on critical reporting dates. We document that stocks held by hedge funds experience higher returns on the last day of the quarter, followed by a reversal the next day. For example, the stocks in the top quartile of hedge...

A random variable dominates another random variable with respect to the covariance order if the covariance of any two monotone increasing functions of this variable is smaller. We characterize completely the covariance order, give strong sufficient conditions for it, present a number of examples...

This chapter surveys theoretical research on the long-term performance of fixed-mix investment strategies. These self-financing strategies rebalance the portfolio over time so as to keep constant the proportions of wealth invested in various assets. The main result is that wealth can be grown...

Private equity has traditionally been thought to provide diversi cation bene ts. However, these benefi ts may be lower than anticipated. We find that private equity suffers from signifi cant exposure to the same liquidity risk factor as public equity and other alternative asset classes. The...

This paper presents an equilibrium model in a pure exchange economy when investors have three possible sources of heterogeneity. Investors may differ in their beliefs, in their level of risk aversion and in their time preference rate. We study the impact of investors heterogeneity on the...

We study survival, price impact and portfolio impact in heterogeneous economies. We show that, under the equilibrium risk-neutral measure, long-run price impact is in fact equivalent to survival, whereas longrun portfolio impact is equivalent to survival under an agent-specific, wealth-forward...
