This paper introduces new nonparametric statistical methods to evaluate zero-cost investment strategies. We focus on directional trading strategies, risk-adjusted returns, and the investor's decisions under uncertainty as the core of our analysis. By relying on classification tools with a long...

Using a randomized experiment with an automobile manufacturing firm in China, we measure the effects of letting workers evaluate their managers on worker and firm outcomes. In the treatment teams, workers evaluate their supervisors monthly. We find that providing feedback leads to significant...

We study the impact of government-led incentive systems by examining a staggered reform in the Chinese state-owned enterprise (SOE) performance evaluation policy. To improve capital allocative efficiency, in 2010, regulators switched from using return on equity (ROE) to economic value added...

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...

We survey more than 200 private equity (PE) managers from firms with $1.9 trillion of assets under management (AUM) about their portfolio performance, decisionmaking and activities during the Covid-19 pandemic. Given that PE managers have significant incentives to maximize value, their actions...

This paper presents a thorough evaluation of target date funds for the period 2010-2020. These funds have grown enormously in assets, reaching $1.4 trillion by the end of 2019. They account for approximately 24 percent of all of the assets in 401(k) accounts. The paper reports on the results of...

Portfolio performance measures using holdings data are panel regressions. The returns of a fund's stocks are regressed on its lagged portfolio weights. Stock fixed effects isolate average performance from time-series predictive ability. Control variables condition fund performance on the...

We examine the performance of the offshore hedge fund industry over the period 1989 through 1995 using a database that includes defunct as well as currently operating funds. The industry is characterized by high attrition rates of funds and little evidence of differential manager skill. We...

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...
