Many financial decisions that individuals face are complicated and daunting for those who are not financial experts. One important consequence of this complexity is that individuals procrastinate in making these decisions. In this paper, we evaluate a low-cost intervention designed to simplify...

Revealed preferences are tastes that rationalize an economic agent's observed actions. Normative preferences represent the agent's actual interests. It sometimes makes sense to assume that revealed preferences are identical to normative preferences. But there are many cases where this assumption...

It is typically difficult to determine whether households invest optimally. But sometimes, investment incentives are strong enough to create sharp normative restrictions. We identify employees at seven companies who are eligible to receive employer matching contributions in their 401(k) and can...

We document a flypaper effect in asset allocation: securities received in kind "stick where they hit." We study a firm that twice changed the rules governing the securities in which its 401(k) matching contributions were initially invested. Both of these rule changes were economically neutral:...

We show that individual investors over-extrapolate

Experimental subjects allocate $10,000 across four S&P 500 index funds. Subject rewards depend on the chosen portfolio's subsequent return. Because the investments are not actually intermediated by the fund companies, portfolio returns are unbundled from non-portfolio services. The optimal...

We provide evidence that time and risk preference norms tied to social identities help shape observed U.S. demographic patterns in economic outcomes. We identify the marginal effect of norms by measuring how laboratory subjects' choices change when an aspect of social identity is made salient....

This paper examines the information embedded in both the stock and option markets prior to takeover announcements. During normal periods, buyer-seller initiated stock volume imbalances are significant predictors of next-day stock returns and option volume imbalances are uninformative. However,...

This paper parsimoniously characterizes how past returns affect the cross-section of expected returns. Using Fama-MacBeth regressions, it shows that the momentum and reversals associated with past returns over va

Despite the interest in measuring price sensitivity of online consumers, most academic work on Internet commerce is hindered by a lack of data on quality. In this paper we use publicly available data on the sales ranks of about 20,000 books to derive quantity proxies at the two leading online...
