We use a novel experimental design to disentangle strategically- and non-strategically-motivated cooperation. By using contingent responses in a repeated sequential prisoners' dilemma with a known probabilistic end, we differentiate end-game behavior from continuation behavior within individuals...

We test if cooperation is promoted by rank-order competition between groups in which all groups can be ranked first, i.e. when everyone can be a winner. This type of rank-order competition has the advantage that it can eliminate the negative externality a group's performance imposes on other...

The ability of groups to implement efficiency-enhancing institutions is emerging as a central theme of research in economics. This paper explores voting on a scheme of intergroup competition, which facilitates cooperation in a social dilemma situation. Experimental results show that the...

In public good provision, privileged groups enjoy the advantage that some of its membersfind it optimal to supply a positive amount of the public good. However, their inherentasymmetric nature may make the enforcement of cooperative behavior through informalsanctioning harder to accomplish...
