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...

Transparency in teams can induce cooperation. We study contribution decisions by agents when previous decisions can be observed. We find that an information chain, in which each agent directly observes only the decision of her immediate predecessor, is at least as effective as a...

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...

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...

This paper discusses several features of knowledge that are often considered crucial for characterizing the economic significance of knowledge: whether it is overtly accessible or tacit, whether it can be or is encoded or not, and whether it has public or private good character. It is argued...
