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...

Although mutual funds exhibit little ability to persistently outperform their peers, money flows into funds with the highest past returns. Berk and Green (2004) rationalize these patterns by arguing that more-skilled managers manage more assets but, because of diseconomies of scale, generate the...

Oregon's Public Employees Retirement System (PERS) is a rich setting in which to study the effect of pension design on employer costs and employee retirement-timing decisions. PERS pays retirees the maximum benefit calculated using three formulas that can be characterized as defined benefit...

The recent growth in the market for target-date funds (TDFs) allows us to study how mutual fund families structure new investment products. Given the widespread, legislation-induced use of TDFs as default investments in defined contribution retirement plans, this market holds special policy...

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...

Within the Oregon University System's defined contribution retirement plan, one investment provider offers access to face-to-face financial advice through its network of brokers. We find that younger, less highly educated, and less highly paid employees are more likely to choose this provider....

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 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...

Standard Fama-French and Carhart models produce economically and statistically significant nonzero alphas, even for passive benchmark indices such as the S&P 500 and Russell 2000. We find that these alphas arise primarily from the disproportionate weight the Fama-French factors place on small...

This paper compares retrospective and prospective analyses of the effect of flip charts on test scores in rural Kenyan schools. Retrospective estimates that focus on subjects for which flip charts are used suggest that flip charts raise test scores by up to 20 percent of a standard deviation....
