Revealing the identities of contributors has been shown to increase cooperation in public goods games. In this paper we experimentally investigate whether this finding holds true when decisions are made by groups rather than individuals. We distinguish between groups in which members can discuss...

Individuals and two-person teams play a hidden - action trust game with pre - play communication. We replicate previous results for individuals that non-binding promises increase cooperation rates. But this does not extend to teams. Wh ile teams make non-binding promises to cooperate at the same...

Costless and non-binding pre-play communication (cheap talk) has been found to often be effective in achieving efficient outcomes in experimental games. However, in previous two-player experimental games each player was informed about both his payoff and the action of the other player in the...

An effective way to foster cooperation is to monitor behaviour and sanction freeriding. Yet, previous studies have shown that cooperation quickly declines when sanctioning mechanisms are removed. We test if explicitly expressing trust in players' capability to maintain cooperation after the...

We compare communication about private information to communication about actions in a one-shot 2-person public good game with private information. The informed player, who knows the exact return from contributing and whose contribution is unobserved, can send a message about the return or her...

Numerous studies suggest that communication may be a universal means to mitigate collective action problems. In this study, we challenge this view and show that the communication structure crucially determines whether communication mitigates or intensifies the problem of collective action. We...

Numerous studies suggest that communication may be a universal means to mitigate collective action problems. In this study, we challenge this view and show that the communication structure crucially determines whether communication mitigates or intensifies rent-seeking for pure public goods. We...
