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...

This paper studies whether and why algorithmic traders exhibit one of the most broadlydocumented behavioral puzzles - the disposition effect. We use trade data from the NASDAQ Copenhagen Stock Exchange merged with the weather data. We find that on average, the disposition effect for human...

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,...

This paper reports the results of 13 experimental asset markets with 195 subjects that explore the effects of insider behavior on the price formation process and market liquidity. The experimental call markets use a more realistic design than related studies. We introduce infinitely-lived assets...

In an experimental setting in which investors can entrust their money to traders, we investigate how compensation schemes affect liquidity provision and asset prices. Investors face a trade-off between risk and return. At the benefit of a potentially higher return, they can entrust their money...
