Monitoring by peers is often an effective means of attenuating incentive problems. Most explanations of the efficacy of mutual monitoring rely either on small group size or on a version of the Folk theorem with repeated interactions which requires reasonably accurate public information...

This paper experimentally studies two simple interventions aimed at increasing public goods provision in settings in which accurate feedback about contributions is not available. The first intervention aims to exploit lying aversion by requiring subjects to send a non-verifiable ex post...

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 experimentally studies two simple interventions that an authority figure might employ to promote cooperation in a public goods game when accurate feedback about contributions is not available. The first intervention aims to nudge participants to higher contribution levels by labeling...

Previous research indicates that risky and uncertain marginal returnsfrom the public good significantly lower contributions. This paper presentsexperimental results illustrating that the effects of risk and uncertainty dependon the employed parameterization. Specifically, if the value of the...

We examine the effects of leading by example in voluntary contributionexperiments. Leadership is implemented by letting one group membercontribute to the public good before followers do. Such leadershipincreases contributions in comparison to the standard voluntary contributionmechanism,...

We consider a society composed of two regions. Each of them pro-vides a public good whose benefits reach beyond local boundaries.In case of decentralization, taxes collected by members of a regionare spent only on that region's public good. In case of centralization, tax receipts from the two...
