We test if cooperation is promoted by rank-order competition between groups in which all groups can be ranked first, i … are absent if groups perform at the same level and it therefore does not eliminate low-cooperation equilibria. We find … that all-can-win competition produces a universal increase in cooperation and benefits a majority of individuals if …

The application of sanctions activates a virtuous emotional circle that accompanies cooperation. Emotionally aroused … punished, and increase their subsequent level of cooperation.

This paper studies the effect of endogenous group formation on the outcome in two types of coordination games with … more groups within which they want to play the coordination game. In the theoretical part we show that a simple myopic best … reply dynamics under endogenous group formation leads to the payoff dominant outcome in both types of coordination games …
