We study a fundamental conflict in economic decision-making, the trade-off between equality, equity and incentives, in a new experimental game that nests a voluntary contributions mechanism in a broader spectrum of incentive schemes. In a 2×2 design, we let subjects either vote on or...

This paper reviews some of the economic experimental evidence on conformism. There is nothing to match the early psychology experiments where subjects were often swayed by the behaviour of others to an extraordinary degree, but there is plenty of evidence of conformism. This seems built-in to...

This paper examines whether and how cheap talk communication can facilitate within-group coordination when two unequal sized groups compete for a prize that is shared equally among members of the winning group, regardless of their (costly) contributions to the group's success. We find that...

We test a mechanism whereby groups are formed voluntarily, through the use of voting. These groups play a public-goods game, where efficiency increases with group size (up to a limit, in one treatment). It is feasible to exclude group members, to exit one's group, or to form larger groups...

We compare the effects of and the motivations behind voluntary punishment and reward in a finitely repeated public goods game. Our experimental results show that (1) the level of cooperation is indistinguishable between the punishment and reward treatments when group membership does not change,...
