We investigate leading by example in a public goods game in scenarios with and without intergroup competition. Leading by example is implemented via a sequential decision protocol. We examine both one-shot and repeated interaction and make use of the strategy method to characterize followers'...

Koukoumelis et al. (2010, 2012) have shown that one-way communication enhances contributions to public goods. We investigate the effectiveness of one-way communication, when the benefits from the public good are asymmetric and the sender of a message is the main beneficiary of cooperation. Our...

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...

Costly signaling of commitment to a group has been proposed as an explanation for participation in religion and ritual. But if the signal's cost is too small, freeriders will send the signal and behave selflshly later. Effective signaling may then be prohibitively costly. If the average level of...

Extensive research on human cooperation in social dilemmas has shown that individuals condition their behaviour upon the behaviour of others. However, few attempts have been made to disentangle the motivations backing conditional cooperation. We try to assess the relative importance of three...

The emergence of Pay-What-You-Want (PWYW) business models as a successful alternative to conventional uniform pricing brings up new questions related to the task of pricing. We investigate the eect of a reduction of privacy on consumers' purchase decisions (whether to buy, and if so how much to...

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...

We propose and develop a model of behavior in threshold public good games. The model draws on learning direction theory and impulse balance theory. We find good support for the model and demonstrate that it can explain the success rates observed in threshold public good experiments. The model is...

In a series of one-shot linear public goods game, we ask subjects to report their contributions, their contribution plans for the next period, and their first-order beliefs about their present and future partner. We estimate subjects' preferences from plans data by a finite mixture approach and...

We report threshold public good experiments in which group members not only need to be individually willing to contribute enough to provide the public good but also have to agree with each other on what every group members should contribute. We find strong support to the hypothesis that full...
