|February 2012||Small Cues Change Savings Choices|
with James J. Choi, Emily Haisley, Jennifer Kurkoski: w17843
In randomized field experiments, we embedded one- to two-sentence anchoring, goal-setting, or savings threshold cues in emails to employees about their 401(k) savings plan. We find that anchors increase or decrease 401(k) contribution rates by up to 1.9% of income. A high savings goal example raises contribution rates by up to 2.2% of income. Highlighting a higher savings threshold in the match incentive structure raises contributions by up to 1.5% of income relative to highlighting the lower threshold. Highlighting the maximum possible contribution rate raises contribution rates by up to 2.9% of income among low savers.

|September 2010||The Importance of Being an Optimist: Evidence from Labor Markets|
with Ron Kaniel, David T. Robinson: w16328
Dispositional optimism is a personality trait associated with individuals who believe, either rightly or wrongly, that in general good things tend to happen to them more often than bad things. Using a novel longitudinal data set that tracks the job search performance of MBA students, we show that dispositional optimists experience significantly better job search outcomes than pessimists with similar skills. During the job search process, they spend less effort searching and are offered jobs more quickly. They are choosier and are more likely to be promoted than others. Although we find optimists are more charismatic and are perceived by others to be more likely to succeed, these factors alone do not explain away the findings. Most of the effect of optimism on economic outcomes stems from t...
|April 2005||Overconfidence vs. Market Efficiency in the National Football League|
with Richard Thaler: w11270
A question of increasing interest to researchers in a variety of fields is whether the incentives and experience present in many "real world" settings mitigate judgment and decision-making biases. To investigate this question, we analyze the decision making of National Football League teams during their annual player draft. This is a domain in which incentives are exceedingly high and the opportunities for learning rich. It is also a domain in which multiple psychological factors suggest teams may overvalue the "right to choose" in the draft -- non-regressive predictions, overconfidence, the winner's curse and false consensus all suggest a bias in this direction. Using archival data on draft-day trades, player performance and compensation, we compare the market value of draft picks with th...
