We show how to bound the effect of belief-dependent preferences on choices in sequential two-player games without information about the (higher-order) beliefs of players. The approach can be applied to a class of belief-dependent preferences which includes reciprocity (Dufwenberg and...

Our research investigates whether social preferences are stable across contexts in the field. We build a unique data set by recruiting participants from a low-income urban neighborhood to participate in a series of laboratory experiments. Their decisions are used to demonstrate the stability of...

This paper investigates the pro-social behaviour among unemployed individuals. We observe two different groups in the field; one includes unemployed individuals who work voluntarily in parallel to receiving unemployment benefits and the other includes unemployed individuals who do not work or who...

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....

We investigate the external validity of giving in the dictator game by using the misdirected letter technique in a within-subject design. First, subjects participated in standard dictator games (double blind) conducted in labs in two different studies. Second, after four to five weeks (study 1)...

We analyze the behavior of game-show contestants who play a one-shot game called Friend or Foe. While it is a weakly dominant strategy not to cooperate, almost half the contestants on the show choose to play "friend." Remarkably, the behavior of contestants remains unchanged even when stakes are...

We conduct an artefactual field experiment to study and compare the behavior of workers and students in a linear voluntary contribution mechanism in which subjects can assign immaterial sanctions or rewards to the other group members. We find that both students and workers sanction group members...

Identifying who engages in inter-group conflict – and if they do so why – may help to predict and potentially prevent inter-group conflicts. Yet, little is known about the heterogeneity of individuals' social preferences in inter-group conflict. We derive a typology and measure of...

We examine high stakes three-person bargaining in a game show where contestants bargain over a large money amount that is split into three unequal shares. We find that individual behavior and outcomes are strongly influenced by equity concerns: those who contributed more to the jackpot claim...

The adoption of solar energy – widely assumed to be pivotal to a new energy transformation – has been hindered by persistent information gaps. Recent literature states the importance of using behavioral science to address the persistent gaps between the technical potential of low carbon...
