(Forthcoming), "Portfolio turnover activity and mutual fund performance", Managerial Finance.
The purpose of this paper is to propose a new measure of portfolio activity, the modified turnover (MT), which represents the portion of the portfolio that the manager changes from one quarter to the next. Compared with the traditional turnover, the MT measure has a distinct interpretation, relies on portfolio holdings, includes the effects of flows and ignores the effects of offsetting trades.
Using quarterly holdings data, the authors examine the relationship between fund turnover, performance, and flows for a sample of 2,856 actively managed mutual funds over the period 1991-2012. The authors provide numerical examples to illustrate how the suggested measure, MT, is different from the traditional turnover measure. The authors use panel regressions, simple and double sorts to examine the predictability of performance.
The authors find evidence that high MT predicts lower performance. The comparison between the highest and lowest quintiles sorted based on MT reveals a difference of −2.41 percent in the annual risk-adjusted return. Furthermore, high MT predicts lower net flows. The authors also find that MT relates positively to other activeness measures while volatility, flows, size, number of stocks, and the expense ratio are significant determinants of MT. Overall, the results suggest that frequent churning of a portfolio is value destroying for investors and signals a manager’s lack of skill.
The authors offer a simple measure, namely, MT, for estimating the fraction of a portfolio that changes from one quarter to the next. Armed with this tool, the authors investigate whether funds deviate from their previous quarter’s holdings because of valuable or noisy information, and whether such signals are exploited by fund investors.

(Forthcoming), "Going to Haven? Corporate Social Responsibility and Tax Avoidance", Journal of Business Ethics.
Abstract: This study examines the endogenous relation between corporate social responsibility (CSR) and tax avoidance by focusing on a common strategy of corporate tax avoidance, i.e., establishing entities in offshore tax havens. Using hand-collected data on a sample of U.S. firms, we find that firms’ CSR ratings increase substantially in the two years after they first open tax haven affiliates. We provide evidence by using the controlled foreign corporations (CFC) look-through rule enacted by Congress in 2006 that facilitates offshore profit shifting. We find that firms that are affected by the CFC legislation increase their CSR practices in response. Overall, our results are consistent with the risk management theory, which argues that firms hedge against the potential negative consequences of aggressive tax avoidance practices through an increase in positive CSR activities.

2017, "To Group or Not To Group? Evidence from Mutual Funds", Journal of Financial and Quantitative Analysis, October 52(5): 1989 - 2021.
Abstract: Despite the overwhelming trend in mutual funds towards team management, empirical studies find no performance benefits for this phenomenon. We show it is caused by large discrepancies in reported managerial structures in CRSP and Morningstar Principia datasets versus SEC records, resulting in up to 50 bps underestimation of the team impact on fund returns. Using more accurate Morningstar Direct data, we find that team-managed funds outperform single-managed funds across various performance metrics. The relation between team size and fund performance is nonlinear. Also, team-managed funds take no more risk than single-managed funds. Overall, team management benefits the fund industry performance.
