Common identity and peer punishment have been identified as important means to reduce free riding and to promote cooperation in teamwork settings. This paper examines the relative importance of these two mechanisms, as well as the importance of income distribution in team cooperation. In a...

In contrast to previous studies on cross-group comparisons of conditional cooperation, this study keeps cross- and within-country dimensions constant. The results reveal significantly different cooperation behavior between social groups in the same location.<p>

Studies have shown that there are differences in cooperative behavior across countries. Furthermore, differences in the use and the reaction on the introduction of a norm enforcement mechansism have been documented in cross-cultural studies, recently. We present data which prove that stark...

This paper investigates whether disclosure crowds out pro-social behavior using a public goods experiment. In a between-subject design, we investigate different degrees of disclosure. We find a small positive but insignificant effect of disclosure treatments on contributions to the public good....

Empirical evidence suggests that people’s maximum willingness to pay for having a good is often substantially lower than their minimum willingness to accept not having it, and that this discrepancy tends to be especially large when valuing public goods. This paper hypothesizes that differences...

The effect of session size has largely been ignored in experimental studies, despite the possibility that it may play a role by changing people’s perception of the potential chance of encountering a certain type of people and by affecting the strength of the potential link between people. This...

In this paper we assume that a public project creates different payoffs to different contributors. Within this environment we study two institutions: Rank Order Voluntary Contribution Mechanism (Rank-Order-VCM) and Random Order Voluntary Contribution Mechanism (Random-Order-VCM). In...

While many earlier studies have found that people’s maximum willingness to pay for having a good is often substantially lower than their minimum willingness to accept not having it, more recent experimental evidence suggests that this discrepancy vanishes for standard consumption goods when an...

A number of low- and middle-income countries have a severe shortage of health workers. This paper studies how health workers’ choices of labour supply and work effort impact on the quality of health services when health workers are in short supply. We analyse how policy measures such as...

We study the impact of anticipated face-to-face discussions among group members after they have made an anonymous contribution to a public good in an experimental setting. We find that the impact of anticipated discussions depends on how we frame the public good game. When framed in...
