The effects of repeated induction of emotions on cooperation and punishment
通过实验研究在公共品博弈中重复诱导的快乐和愤怒情绪如何影响合作与惩罚的动态，发现快乐可能因受罚者的反应而损害合作，而愤怒则使合作保持稳定。
Abstract This study experimentally investigates how repeatedly‐induced exogenous happiness and anger affect the dynamics of cooperation and punishment in a public good game with repeated trials, wherein costly punishment is available and stranger matching is used. The study finds that induced happiness may harm cooperation when the reactions of the punished are also considered. Indeed, contributions in the happiness treatment decay with each round, while those in the anger treatment are stable. The main reason for this is found to be that the antisocial‐punished cooperators in the happiness treatment reduce their contributions, while those in the anger treatment do not.
