Many previous experiments document that behavior in multi-person settings responds to the name of the game and the labeling of strategies. Usually these studies cannot tell whether frames affect preferences or beliefs. In this Dictator game study, we investigate whether social framing effects...

We perform a meta analysis of gender differences in the dictator game (DG) by collecting raw data from 53 studies with 117 conditions, giving us 15,016 unique individual observations. We find that women on average give 4 percentage points more than men (Cohen's d=0.16), and that this difference...

While headline news frequently report cases of large-scale fraud, corruption, and other immoral behavior, laboratory experiments often show prosocial behavior in strategic games. To reconcile and explain these seemingly conflicting observations, Al'os-Ferrer et al. (2022) introduced the Big...

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...

We explore how risk-taking in the card game contract bridge, and in a financial gamble, correlate with variation in the dopamine receptor D4 gene (DRD4) among serious tournament bridge players. In bridge risk-taking, we find significant interactions between genetic predisposition and skill....
