Costless pre-play communication has been found to effectively facilitate coordination and enhance efficiency by increasing individual payoffs in games with Pareto-ranked equilibria. We report an experiment in which two groups compete in a weakest-link contest by expending costly efforts....

Costless pre-play communication has been found to effectively facilitate coordination and enhance efficiency in games with Pareto-ranked equilibria. We report an experiment in which two groups compete in a weakest-link contest by expending costly efforts. Allowing intra-group communication leads...

MWe experimentally investigate simultaneous decision-making in two contrasting environments: a competitive environment (a contest) and a cooperative environment (a voluntary contribution mechanism). We find that the cooperative nature of the voluntary contribution mechanism spills over to the...

The current social dilemma literature lacks theoretical consensus regarding how individuals behave when facing multiple simultaneous social dilemmas. The divided-loyalty hypothesis, from organizational theory, predicts that cooperation will decline as individuals experience multiple social...
