We analyze the offering, asking, and granting of help or other benefits as a three-stage game with bilateral private information between a person in need of help and a potential help-giver. Asking entails the risk of rejection, which can be painful: since unawareness of the need can no longer be...

We experimentally examine how the incentive to defect in a social dilemma affects conditional cooperation. In our first study we conduct online experiments in which subjects play eight Sequential Prisoner's Dilemma games with payoffs systematically varied across games. We find that few second...

We introduce "group cohesion" to study the economic relevance of social relationships in team production. We operationalize measurement of group cohesion, adapting the "oneness scale" from psychology. A series of experiments, including a pre-registered replication, reveals strong positive...

We investigate in a laboratory setting whether revealing information on the intelligence of both players affects behavior in repeated games. We study the Prisoners' Dilemma (PD) and Battle of Sexes (BoS) as they cover a large set of the interesting scenarios generated by repeated games of two...

We document the effect of unemployment insurance generosity on divorce and fertility using an identification strategy that leverages state-level changes in maximum benefits over time and comparisons across workers who have been laid off and those that have not been laid off. The results indicate...

Increasing inequality and associated egalitarian sentiments have again put redistribution on the political agenda. Other-regarding preferences may also affect support for redistribution, but knowledge about their distribution in the broader population and how they are associated with political...

Peer observation can influence social norm perceptions as well as behavior in various moral domains, but is the tendency to be influenced by and conform with peers domain-general? In an online experiment (N = 815), we studied peer effects in honesty and cooperation and tested the...

Response times are a simple low-cost indicator of the process of reasoning in strategic games (Rubinstein, 2007; Rubinstein, 2016). We leverage the dynamic nature of response-time data from repeated strategic interactions to measure the strategic complexity of a situation by how long people think on...

We model a contest between two groups of equal population size over the division of a group-specific public good. Each group is fragmented into sub-groups. Each sub-group allocates effort between production and contestation. There is perfect coordination within sub-groups, but sub-groups cannot...

There is little consensus on whether women are more generous than men; some research results indicate a higher propensity towards giving of female dictators, whilst others suggest the opposite. Two explanations have been put forward. According to the first one, women are more generous than men...
