We develop and test a framework of mental information representation in an asset market setting. The model predicts heterogeneous trading behavior as a consequence of two distinct mental capabilities: analytical skills and mentalizing, where the former involves quantitative, objective aspects of...

In a pre-registered laboratory asset market study, we investigate dynamics of asset markets with zero (or close to zero) fundamental values. We introduce the "greater fool asset market game" with a zero-value token, whose price doubles in each period. We design several treatments, which differ...

This paper examines the relation between investor attention and stock market anomalies in the US stock market. We find anomalies are stronger following high rather than low attention periods. Returns on the long–short strategy based on a composite mispricing score during high attention months...

We first provide evidence of some retail investors taking real trading (selling) decisions which are clearly sub-optimal even from an ex-ante perspective. We then show that these investors also exhibit stronger investment biases, namely, the disposition effect, underdiversification, preference...

Financial markets and economic conditions induce stress, but does stress, in turn, have a causal effect on investor behavior and markets? We analyze this question in bubble-prone experimental asset markets with 492 participants. We induce acute stress, which we measure with cortisol levels,...
