We examine why heterogenous communities may fail to provide public goods. Current work characterizes sanctioning free-riders as an under-supplied public good. We argue that often free-riders can be punished by the coordinated action of a group. This punishment can be profitable, and need not be...

Do better informed people vote more? Recent theories of voter turnout emphasize a positive effect of being informed on the propensity to vote, but the possibility of endogenous information acquisition makes estimation of causal effects difficult. I estimate the causal effects of being informed...

In a society composed of citizens and a dictator: what are the conditions for a successful citizens' revolt? What kind of strategies do governments follow to prevent such revolts? In this paper we argue that the concept of networks is a very powerful tool to understand these issues, as shown...

We combine societal-level institutional measures from 51 countries between 1996 and 2017 with individual decision-making outcome data from 1,126 laboratory experiments in six meta-analyses to evaluate the effects of within-country institutional change on pro-social and Nash behavior. We find...

The causes of people's political attitudes are largely unknown. We study this issue by exploiting longitudinal data on lottery winners. Comparing people before and after a lottery windfall, we show that winners tend to switch towards support for a right-wing political party and to become less...

Experiments have demonstrated that men are more willing to compete than women in stereotypically male tasks. We examine whether nominations close this gender gap. For example, are male nominators more willing than female nominators to enter nominees into competitions. Further, we consider the...

The study at hand deals with the expectations of professional analysts and novices in the context of foreign exchange markets. We analyze the respective forecasting accuracy and our results indicate that there exist substantial differences between professional forecasts and judgmental forecasts...

We study, experimentally, how two alternative incentive mechanisms affect team performance, and how a team chooses between alternative mechanisms. We study a group incentive mechanism, where team output is shared equally among team members, and a hierarchical mechanism team output is allocated...

This paper compares two methods to encourage socially optimal provision of a public good. We compare the efficacy of vigilante justice, as represented by peer-to-peer punishment, to delegated policing, as represented by the “hired gun” mechanism, to deter free riding and improve group...

Safety nets may reduce incentives to mitigate risks, and adversely affect people’s behavior. We model the safety net problem as a social dilemma game involving moral hazard, risk taking and limited liability. Individuals take costly measures to avoid a likely loss which, if incurred, is...
