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...

We investigate the dynamic effects of a charitable lottery and an income tax on donations. The analysis is based on a two-round dictator game with the subject’s charity of choice as recipient and additional incentives in the first round only. The immediate effect of a charitable lottery leads...

Social norms can help to foster cooperation and to overcome the free-rider problem in private provision of public goods. This paper focuses on the enforcement of social norms by a self-introduced punishment and reward scheme. We analyse if subjects achieve to implement a norm-enforcement...

Many public goods can be provided at different spatial levels. Evidence from social identity theory and in-group favoritism raises the possibility that where higher-level provision is more efficient, subjects' narrow concern for local outcomes (parochialism) could harm efficiency. Building on...
