We study ESG and non-ESG mutual funds managed by overlapping teams. We find that non-ESG mutual funds include more high ESG stocks after the creation of an ESG sibling, and the high ESG stocks they select exhibit superior performance. The low ESG stocks selected by ESG funds also exhibit...

We study the relation between mutual fund managers' family backgrounds and their professional performance. Using hand-collected data from individual Census records on the wealth and income of managers' parents, we find that managers from poor families deliver higher alphas than managers from...

We establish an important role for the firm by studying capital reallocation decisions of mutual fund firms. At least 30% of the value mutual fund managers add can be attributed to the firm's role in efficiently allocating capital amongst its mutual fund managers. We find no evidence of a...

Using the dollar-value a mutual fund manager adds as the measure of skill, we find that not only does skill exist (the average mutual fund manager adds about $2 million per year), but this skill is persistent, as far out as 10 years. We further document that investors recognize this skill and...

Mutual fund managers can outperform the market by picking stocks or timing the market successfully. Previous work has estimated picking and timing skill, assuming that each manager is endowed with a fixed amount of each and found some evidence of picking skills and little evidence of timing...

We argue that active management's popularity is not puzzling despite the industry's poor track record. Our explanation features decreasing returns to scale: As the industry's size increases, every manager's ability to outperform passive benchmarks declines. The poor track record occurred before...

Mutual funds change their risk levels significantly over time. This paper investigates the performance consequences of risk shifting, as well as the economic motivations and the mechanisms of risk shifting. Using a holdings-based measure of risk shifting, we find that funds that increase risk...

Financial economists have long been puzzled by investor demand for actively managed funds that generate, on average, negative after-fee, risk-adjusted returns. To shed new light on this puzzle, we exploit the fact that funds in different market segments compete for different types of retail...
