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...

We explored experimentally how threshold uncertainty affects coordination success in a threshold public goods game. Whereas all groups succeeded in providing the public good when the exact value of the threshold was known, uncertainty was generally detrimental for the public good provision. The...

Theories about unique equilibrium selection are often rejected in experimental investigations. We drop the idea of selecting a single prominent equilibrium but suggest the coexistence of different beliefs about "appropriate" equilibrium or non-equilibrium play. Our main selection criterion is...
