Household demand for actuarially unfair insurance against small risks has long puzzled economists. One way to potentially rationalize this demand is to recognize that (non-life) insurance is an incentive-compatible means of engaging an expert buyer. To quantify the benefits of expert buying, we...

The level of diseconomies of scale in asset management has important implications for tests of manager skill and the expected level of performance persistence. To identify the causal impact of fund size on future returns, we exploit the fact that small differences in returns can cause discrete...

I review the academic literature on defined contribution retirement plan design and participant behavior. While adoption of automatic enrollment has significantly increased participation rates, recent studies find the long-run effects on savings are smaller than the short-run effects, with some...

Transparency is usually thought to reduce favoritism and corruption by facilitating monitoring by outsiders, but there is concern it can have the perverse effect of facilitating collusion by insiders. In response to vote trading scandals in the 1998 and 2002 Olympics, the International Skating...

This paper examines the problem of a college affected by both a legal ban on affirmative action in admissions and pressure to raise enrollment of underrepresented minorities (URMs), as exemplified by UCLA, which adopted a holistic admissions process in 2006 in response to protests over low URM...

We examine whether credit rating agencies reward accurate or biased analysts. Using data collected from Moody's corporate debt credit reports, we find that Moody's is more likely to promote analysts who are accurate, but less likely to promote analysts who downgrade frequently. Combined,...

Following the Pension Protection Act of 2006, there was a sharp increase in the use of TDFs as default investment options in defined contribution retirement plans. We document large differences in realized TDF returns and risk profiles, even for funds with the same target retirement date. Using...

We study the impact of investor heterogeneity on mutual fund market segmentation. To motivate our empirical analysis, we make two assumptions. First, some investors inherently value broker services. Second, because brokers are only compensated when they sell mutual funds, they have little...

Economists have long been puzzled by the low demand for life annuities. To shed new light on this puzzle, we study payout choices in the Oregon Public Employees Retirement System, where each retiree must choose between a lump sum and a life annuity. Notably, the average life annuity we study is...

We analyze the behavior of 401(k) plan participants during the first quarter of 2020, when COVID-19 generated historic volatility, large negative returns, and significant unemployment. Only 2.1% of participants invested in TDFs made any changes to their portfolios, with even lower rates of...
