We investigate the effect of intragroup competition and risky marginal per capita returns on subjects' cooperative behavior in a one-shot public good game – following the wellknown approach proposed by Fischbacher, Gächter, and Fehr (2001) and extending the Colasante et al. (2019) and...

This paper evaluates the role of centralized punishment in boosting contribution to the provision of public goods. To avoid the race to the bottom in the provision of public goods, this centralized punishment mechanism relies on the use of the unilateral and tie punishment imposed on the lowest...

We propose a new, voluntary mechanism (the "hybrid lottery") as a means for financing the provision of public goods. We find that, under some conditions, the mechanism can mitigate the free-riding problem and that, for each player, the (weakly) dominant strategy is the one that -in equilibrium-...

Exogenously imposed infinite repetition is known to mitigate people’s uncooperative behaviors in dilemma situations with partner matching through personal enforcement. One as yet unanswered question is whether people collectively choose to interact with each other under the partner matching...

This paper experimentally studies individuals’ voluntary disclosure of past behaviors and its effects in a finitely repeated two-player public goods game. The experiment data found that voluntary information disclosure strengthens cooperation under certain conditions, although a non-negligible...

This experiment investigates contests between groups. Each group has one strong player, with a higher valuation for the prize, and two weak players, with lower valuations. In contests where individual efforts are perfect substitutes, all players expend significantly higher efforts than predicted...

I show how improper conditioning of beliefs can lead to under-contribution in public goods environments with interdependent values. I consider a simple model of a binary, excludable public good. In equilibrium, provision of the public good is good news about its value. Naive players who...

Human conduct is often guided by “conformist preferences”, which thrive on behavioral expectations within a society, with conformity being the act of changing one’s behavior to match the purported beliefs of others. Despite a growing research line considering preferences for a fair outcome...

Governments sometimes promote rules backed by sanctions too weak to make obedience privately optimal. Factors that may help make such rules effective include the presence of informal sanctions by peers, and implementation through voting. I study the impact of non-deterrent formal sanctions on...

We report results from experiments designed to investigate the prevalence of turn-taking in three-person finitely repeated threshold public good games without communication. Individuals can each make a discrete contribution. If the number of contributors is at least equal to the threshold, a...
