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 propose that heterogeneous asset trading behavior is the result of two distinct, non-convertible mental dimensions: analytical ("quantitative") capability and mentalizing ("perspective-taking") capability. We develop a framework of mental capabilities that yields testable predictions about...

The efficiency of financial markets and their potential to produce bubbles are central topics in academic and professional debates. Yet, surprisingly little is known about the contribution of financial professionals to price efficiency. To close this gap, we run 86 experimental markets with 294...

Bubbles are omnipresent in lab experiments with asset markets. Most of these experiments were conducted in environments with only human traders. Today markets are substantially determined by algorithmic traders. Here we use a laboratory experiment to measure changes of human trading behavior if...

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...

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 nudges that (in)directly remind financial advisers of their oath affect their service. In...

There is consensus that the recent financial crisis revolved around a crash of the short-term credit market. Yet there is no agreement around the necessary policies to prevent another credit freeze. In this experiment we test the effects that contract length (i.e. maturity mismatch) has on the...

This paper examines the effect of peers on individual risk taking. In the absence of informational motives, we investigate why social utility concerns may drive peer effects. We test for two main channels: utility from payoff differences and from conforming to the peer. We show experimentally...
