Social information 'nudges' concerning how others perform typically boost individual performances in experiments with one group reference point. However, in many natural settings, sometimes due to policy, there are several such group reference points. We address the complications that such...

Teams often suffer from a free rider problem with respect to individual contributions. That putting teams into competition with each other can mitigate this problem is an important recent insight. However, we know little about how inequality in endowment between teams might influence this...

At least since Adam Smith, economists have recognized the beneficial effects of competition in markets. The possible positive influence of competition between teams on the free rider problem within teams is a more recent discovery. It is important because the free rider problem exists to some...

This paper examines how third-party surveillance influences preferences over distributional outcomes. In addition, we examine what motivates people to invest economic resources to monitor decision-making processes. Our results show that a large majority of individuals is willing to pay for a...

In a repeated public goods setting, we explore whether individuals, acting unilaterally, will provide an effective sanctioning institution. Subjects first choose unilaterally whether they will participate in a sanctioning stage that follows a contribution stage. Only those who gave themselves...

We investigate the effects of the availability of resources that can be expended in conflict on conflict intensity. We run a between-subjects Tullock contest in which we vary the contest budget from Low to Medium to High, while keeping the Nash equilibrium bid the same. We find an 'inverted...

Abundant evidence suggests that high levels of contributions to public goods can be sustained through self-governed monitoring and sanctions. This experimental study investigates the effectiveness of decentralized sanctioning institutions in alternative punishment networks. Our results show that...

We investigate the effects of Partner and Stranger matching in contest experiments and find no difference in the level or distribution of bids across matching protocols. However, demographic and individual strategy effects are different with different matching. Hence, unless one is interested in...
