论文摘要
本文研究了声誉不确定性和社会环境变化率如何决定合作的方式。声誉不确定性大大降低了合作，而瞬息万变的社会环境只会导致合作的二阶定性增加。在个人层面上，声誉不确定性通过链接建议和删除过程施加网络惩罚，引起更多的宽大和宽恕，从而抑制了合作集群的形成。但是，这种效果只有在变化的环境中而不是在慢速变化的环境中才有意义。网络惩罚与行动惩罚之间的替换模式（报复性叛逃）解释了这两个社会环境之间的这种差异。
This paper examines experimentally how reputational uncertainty and the rate of change of the social environment determine cooperation. Reputational uncertainty significantly decreases cooperation, while a fast-changing social environment only causes a second-order qualitative increase in cooperation. At the individual level, reputational uncertainty induces more leniency and forgiveness in imposing network punishment through the link proposal and removal processes, inhibiting the formation of cooperative clusters. However, this effect is significant only in the fast-changing environment and not in the slow-changing environment. A substitution pattern between network punishment and action punishment (retaliatory defection) explains this discrepancy across the two social environments.
