Do returns in private equity (PE) rise or fall with fund scale? This question is increasingly urgent amid larger funds and new focus on the retail market. Since better managers can raise larger funds, the causal effect is difficult to identify. We develop an instrument based on gifts to...

The literature has not unambiguously established that a positive alpha, as traditionally measured, means that an investor would want to buy a fund. However, when alpha is defined using the client's marginal utility function, a client faced with a positive alpha would generally want to buy. When...

A seminal study of persistence in mutual fund performance is Carhart (1997), who found that U.S. equity mutual funds' past-year returns positively predict their raw excess return and one-factor alpha over the next year. Based on these results, an investor may believe that she can earn higher...

We study the long-run outcomes associated with hedge funds' compensation structure. Over a 22-year period, the aggregate effective incentive fee rate is 2.5 times the average contractual rate (i.e., around 50% instead of 20%). Overall, investors collected 36 cents for every dollar earned on...

We survey the recent literature on learning in financial markets. Our main theme is that many financial market phenomena that appear puzzling at first sight are easier to understand once we recognize that parameters in financial models are uncertain and subject to learning. We discuss phenomena...

We show that the standard equation-by-equation OLS used in performance evaluation ignores information in the alpha population and leads to severely biased estimates for the alpha population. We propose a new framework that treats fund alphas as random effects. Our framework allows us to make...

We study the joint determination of fund managers' contracts and equilibrium asset prices. Because of agency frictions, investors make managers' fees more sensitive to performance and benchmark performance against a market index. This makes managers unwilling to deviate from the index and...

Public and private equity waves move together. Using quarterly cash-flow data for a large sample of venture capital and buyout funds from 1984-2010, we investigate the implications of this co-cyclicality for understanding private equity cash flows and performance. In the cross-section, varying...

Measuring the performance of private equity investments (buyout and venture) has historically only been possible over long horizons because the IRR on a fund is only observable following the fund's final distribution. We propose a new approach to evaluating performance using actual prices paid...

We present a comprehensive analysis of the performance and flows of U.S. actively-managed equity mutual funds during the COVID-19 crisis of 2020. We find that most active funds underperform passive benchmarks during the crisis, contradicting a popular hypothesis. Funds with high sustainability...
