The disposition effect describes investors’ common tendency of quitting a winning investment too soon and holding on to losing investments too long (Shefrin and Statman 1985). Our paper analyses individual level disposition effects using both account level field data as well as a controlled...

This paper describes a study, in which we examine the diversification behavior of financial advisors. The Asset Allocation Puzzle describes the phenomenon that popular financial advice tends to be inconsistent with the mutual-fund separation theorem. While Canner, Mankiw and Weil (1997) try to...

Anecdotal evidence and recent theoretical models argue that past stock returns affect subsequent stock trading volume. We study 3,000 individual investors over a 51 month period to test this prediction using linear panel regressions as well as negative binomial panel regressions and Logit panel...

This paper reports the results of experiments on portfolio choice in the presence of nontradeable income. The nontradeable income part could either be riskless or risky (background risk). In many cases, we observe behavior which is qualitatively consistent with the predictions of normative...
