Decision weights are an important component in recent theories for decision making under uncertainty. To better explain these decision weights, a two stage approach has been proposed: first, the probability of an event is judged and then this probability is transformed by the probability...

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...

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...
