I provide evidence that fund managers who overweight firms with the most differentiated products ('monopolies') exhibit a superior risk-adjusted performance. This is consistent with information advantages due to a better understanding of qualitative information on a firm's competitive...

Although the 1940 Act restricts interfund lending within a mutual fund family, families can apply for exemptions from the regulator to participate in interfund lending. We find that heterogeneity in portfolio liquidity and investor flows across funds, funds' investment restrictions, and...

We study the dynamics of fund manager ownership for a sample of U.S. equity mutual funds from 2005 to 2011. We find that ownership changes positively predict changes in future risk-adjusted fund performance. A one-standarddeviation increase in ownership predicts a 1.6 percent increase in alpha...

We analyze what a second business degree reveals about the investment behavior of mutual fund managers. Specifically, we compare performance, risk, and style of managers with both a CFA designation and an MBA degree to managers with only one of these qualifications. We document that the average...

Processing qualitative information about a firm's product market competition matters for fund performance. I find that fund managers with a better understanding of a firm's market power exhibit a superior risk-adjusted performance. Managers who overweight companies with the fewest competitors...

Sexual harassment, a widespread problem in the workplace, arguably keeps female employees from optimally employing their human capital. We show that removing or diminishing this friction improves productivity. Specifically, using the male-dominated fund industry as our testing ground, we show...

We show a long-lasting association between a common societal phenomenon, early-life family disruption, and investment behavior. Fund managers who experienced the death or divorce of their parents during childhood take lower risk and are more likely to sell their holdings following riskincreasing...

Short sellers are perceived as informed, sophisticated investors. Yet little is known about their actual performance and trading strategies. Using a novel, hand-collected data set of daily position disclosures in Europe, we identify the entry, change, and exit dates of large short-sale positions...

This paper analyzes how the existence of sector funds (specialists) within a mutual fund family affects the performance and investment behavior of affiliated diversified equity funds (generalists). First of all, I show that specialists have stock picking skills. Second, information flows from...
