Using simulations and experiments, we pinpoint two main drivers of trader performance: cognitive reflection and theory of mind. Both dimensions facilitate traders' learning about asset valuation. Cognitive reflection helps traders use market signals to update their beliefs whereas theory of mind...

An empirically founded and widely established driving force in opinion dynamics is homophily i.e. the tendency of "birds of a feather" to "flock together". The closer our opinions are the more likely it is that we will interact and converge. Models using these assumptions are called bounded...

We analyze whether differences in market-wide levels of investor personality influence experimental asset market outcomes in terms of price bubbles and levels. We employ a questionnaire to determine investor personality and combine the survey data with data from experimental asset markets. We...

In this paper we study the effect of induced positive mood on price patterns in experimental asset markets. We conduct experimental asset markets where subjects go through a mood induction procedure prior to trade. After the subjects are induced with positive affect, they can trade an...

The efficiency of financial markets, but also their potential to produce bubbles are central topics in academic and professional debates. Yet, little is known about the contribution of financial professionals to price efficiency. We run 116 experimental markets with 412 professionals and 502...

Disposition effect is one phenomenon in behavioral finance that describes investor tendency to sell winner stocks too early and hold loser stocks too long. The purpose of this paper is to examine the disposition effect from investor perspective when they respond to short-run and long-run return...

We examine peer effects in risk taking with complete information and compare explanations for peer effects based on relative payoff concerns to explanations that allow peer choices to matter. We vary experimentally whether individuals can condition a simple lottery choice on the lottery choice,...

Financial misbehavior is widespread and costly. The Dutch government legally requires every employee in the financial sector to take a Hippocratic oath, the so-called "banker's oath.'' We investigate whether moral nudges that directly and indirectly remind financial advisers of their oath affect...
