In public good provision, privileged groups enjoy the advantage that some of its membersfind it optimal to supply a positive amount of the public good. However, their inherentasymmetric nature may make the enforcement of cooperative behavior through informalsanctioning harder to accomplish...

We study two generic versions of public goods problems: in Provision problems, the public good does not exist initially and needs to be provided; in Maintenance problems, the public good already exists and needs to be maintained. In five lab and online experiments (n=2,584), we document a robust...

The ability to punish free-riders can increase the provision of public goods. However, sometimes the benefit of increased public good provision is outweighed by the costs of punishments. One reason a group may punish to the point that net welfare is reduced is that punishment can express anger...

Institutions are an important means for fostering prosocial behaviors, but in many contexts their scope is limited and they govern only a subset of all socially desirable acts. We use a laboratory experiment to study how the presence and nature of an institution that enforces prosocial behavior...

Sanctions are a common method to discourage free-riding in the provision of public goods. However, we can usually only sanction those who are detected performing the bad act of free-riding. There has been considerable research on the type of sanctions imposed, but this research almost always...

Economic and social interaction takes place between individuals with heterogeneous characteristics. We investigate experimentally the emergence and informal enforcement of different contribution norms to a public good in homogeneous and different heterogeneous groups. When punishment is not...

Being perceived as trustworthy comes with substantial economic benefits in many situations. Making other people think you are a trustworthy person may, therefore, be an important motive for charity and other forms of prosocial behavior, provided these activities work as signals of...

We devise a new experimental game by nesting a voluntary contributions mechanism in a broader spectrum of incentive schemes. With it, we study tensions between egalitarianism, equity concerns, self-interest, and the need for incentives. In a 2x2 design, subjects either vote on or exogenously...

Research on public goods mainly focuses its attention on the ability of incentives, beliefs and group structure to affect behaviour in social dilemma interactions. This paper investigates the pure effects of a rather subtle mechanism on social preferences in a one-shot linear public good game....

Experimental studies of social dilemmas have shown that while the existence of a sanctioning institution improves cooperation within groups, it also has a detrimental impact on group earnings in the short run. Could the introduction of pre-play threats to punish have enough of a beneficial...
