We study conditional cooperation based on a sequential two-person linear public good game in which a trusting first contributor can be exploited by a second contributor. After playing this game the first contributor is allowed to punish the second contributor. The consequences of sanctioning...

The provision of public goods regularly embodies interrelated spheres of influence on multiple scales. This article examines the nature of human behavior in a multilevel social dilemma game with positive provision externalities to local and global scales. We report experimental results showing...

Similar to Levati and Neugebauer (2001), a clock is used by which participants can vary their individual contributions for voluntarily providing a public good. As time goes by, participants either in(de)crease their contribution gradually or keep it constant. Groups of two poorly and two richly...

In a situation, where it is efficient for one of two parties to pollute but highly inefficient if both parties do so, the harmed third party can freely impose its damage claims on both parties what crucially determines which equilibrium to expect. Whereas "equality before the law" requires equal...

Participants in a public goods experiment receive private or common signals regarding the so-called "point of no return", meaning that if the group's total contribution falls below this point, all payoffs are reduced. An individual faces the usual conflict between private and collective...

A long time ago most economists would have limited themselves to stating that agreements should be individually rational and efficient and that selecting a specific agreement from that set depends on bargaining and negotiation power whatever that may be. Nowadays hardly any economist will argue...

Based on an axiomatically derived provision rule allowing community members to endogenously determine which, if any, public project should be provided, we perform experiments where (i) not all parties benefit from provision, and (ii) the projects' "costs" can be negative. In the tradition of...

In a duopoly market, aspiration levels express how much sellers want to earn given their expectations about the other's behavior. We augment the sellers' decision task by eliciting their profit aspiration. In a first experimental phase, whenever satisficing is not possible, sales choices, point...

We experimentally analyze leading by example in a public goods game with two permanent and two temporary group members. Our results show that leadership when permanent and temporary members interact leads to lower contributions than interaction without leadership.
