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. …

This paper investigates how punishment promotes cooperation when the punishment enforcer is a third party independent … of the implicated parties who propose the punishment. In a prisoner's dilemma experiment, we find an independent third … party vetoes not only punishment to the cooperators but punishment to the defectors as well. Compared with the case when the …

Motivated by problems of coordination failure observed in weak-link games, we experimentally investigate behavioral … spillovers for minimum- and median-effort coordination games. Subjects play these coordination games simultaneously and … sequentially. The results show that successful coordination on the Pareto optimal equilibrium in the median game influences …

Costless pre-play communication has been found to effectively facilitate coordination and enhance efficiency in games … costly efforts. Allowing intra-group communication leads to more aggressive competition and greater coordination than control … experimental findings from public goods and other coordination games, where communication always enhances efficiency and often …

cooperation or Pareto optimum outcome was about 1%-2%. There were evidence that payoffs perturbation influences players’ decision …

We report a framed field experiment, in which we study the effectiveness of punishment and reward in sustaining … cooperation in a social dilemma. Punishments tend to be directed at non-cooperators and rewards are assigned by those who are … and rewards fail to increase cooperation. …
