We construct a simple three person trust game with one trustor and two trustees. The trustor has the possibility to either trust both trustees or none, while the trustees make their decisions either sequentially or simultaneously, depending on the treatment. When trustees play sequentially,...

Gender equity in the creation and enforcement of social norms is important not only as a normative principle but it can also support long term economic growth. Yet in most societies, coercive power is in the hands of men. We investigate whether this form of segregation is due to gender...

This note uncovers new properties of the von Neumann-Morgenstern solution in weak tournaments and majoritarian games. We propose a new procedure for the construction of choice sets from weak tournaments, based on dynamic stability criteria. The idea is to analyze dynamic versions of the...

We experimentally investigate spillover effects of affirmative action policies on team performance and the willingness to work in teams. We find that such policies in form of gender quotas do not harm performance and cooperation within teams, and do not discourage selection into teams.

We examine the effects of social preferences and beliefs about the social preferences of others in a simple leader-follower voluntary contributions game. We find that groups perform best when led by those who are reciprocally oriented. Part of the effect can be explained by a false consensus...

We report an experiment comparing sequential and simultaneous contributions to a public good in a quasi-linear two-person setting. In one parameterization we find that overall provision is lower under sequential than simultaneous contributions, as predicted, but the distribution of contributions...

We examine the characteristics of effective leaders in a simple leader-follower voluntary contributions game. We focus on two factors: the individual's cooperativeness and the individual's beliefs about the cooperativeness of others. We find that groups perform best when led by those who are...

We compare social preference and social norm based explanations for peer effects in a three-person gift-exchange game experiment. In the experiment a principal pays a wage to each of two agents, who then make effort choices sequentially. In our baseline treatment we observe that the second...

Many situations in the social and economic life are characterized by rivalry and con ict between two or more competing groups. Warfare, socio-political con icts, political elections, lobbying, and R&D competitions are all examples of inter-group con icts in which groups spend scarce and costly...

We report two studies investigating whether, and if so how, different interventions affect voter registration rates. In a natural field experiment conducted before the 2015 UK General Election, we varied messages on a postcard sent by Oxford City Council to unregistered student voters...
