Considerable experimental evidence shows that although costly peer-punishment enhances cooperation in repeated public …-good games, heavy punishment in early rounds leads to average period payoffs below the non-cooperative equilibrium benchmark. In … fall prey to a poverty trap or, to avoid this, abstain from punishment altogether. We show that neither is the case …

The formation of social ties is examined in an experimental study of voluntary public good provision. The experiment …

We use a laboratory experiment to test the impacts of uncertainty, the magnitude of fines and aversion against making …

In this paper we explore the boundary conditions for altruistic punishment to … maintain cooperation by systematically varying the cost and impact of punishment, using a subject pool which extends beyond the …

The effects of stake size on cooperation and punishment are investigated using a public goods experiment. We find that … an increase in stake size does neither significantly affect cooperation nor, interestingly, the level of punishment. …

We elicit human conditional punishment types by conducting experiments. We find that their punishment decisions to an … individual are on average significantly positively proportional to other members’ punishment decisions to that individual. …
