This paper analyses leadership and charisma within the framework of social choice. In societies that lack formal institutional authorities, the power of leaders to coerce is limited. Under such conditions we find that social outcomes will depend not only on policy preferences but also on...

We study spatially differentiated competition between charities by partnering with two foodbanks in two neighboring cities to conduct a field experiment with roughly 350 donation appeals. We induce spatial differentiation by varying the observability of charities' location such that each donor...

Many economic, political and social environments can be described as contests in which agents exert costly efforts while competing over the distribution of a scarce resource. These environments have been studied using Tullock contests, all-pay auctions and rankorder tournaments. This survey...

Traditionally economic theory assumes that preferences are stable facilitating positive predictions of economic policy. While there is conflicting experimental evidence on the temporal stability of cooperation preferences in public goods provision, surprisingly little is known about their...

This study examines individual and group behavior in a linear appropriation game setting. Subjects make decisions from a menu of eight games, without feedback. Four treatment conditions vary the magnitude of the opportunity cost of conservation, including symmetric and asymmetric treatments. A...

This paper studies the effect of leadership on the level and evolution of pro-social behavior using an artefactual field experiment on local public good provision. Participants decide how much to contribute to an actual conservation project. They can then revise their donations after being...

Many public goods can be provided at different spatial levels. Evidence from social identity theory and in-group favoritism raises the possibility that where higher-level provision is more efficient, subjects’ narrow concern for local outcomes (parochialism) could harm efficiency. Building on...

This paper reports an experiment which compares behaviour in two punishment regimes: (i) a standard public goods game with punishment in which subjects are given the opportunity to punish other group members (democratic punishment regime) and (ii) a public goods game environment where all group...

We develop and study a two-period model of political competition with office- and policymotivated candidates, in which (i) changes of policies impose costs on all individuals and (ii) such costs increase with the magnitude of the policy change. We show that there is an optimal positive level of...

We report experimental results from three Colombian villages concerning the impact of a voting mechanism on interpersonal trust and trustworthiness. The vote is purely consultative in that participants are asked to declare in a secret ballot the most “appropriate” plan of action for...
