摘要：
we propose a novel mechanism to mitigate socially undesirable behavior (e.g., pollution, corruption, tax avoidance) framed as the provision of public bads in large groups. players first choose their social network, where having a greater number of partners brings benefits. subsequently, they decide whether to provide a public bad that yields benefits to themselves but imposes costs on the entire society. in the event of providing the public bad, there is a small chance of being detected and subsequently punished. in our proposed responsibility-sharing mechanism, if a player is detected providing the public bad, all their partners also face punishment. both the theoretical analysis and experimental results strongly support the effectiveness of this mechanism in inducing socially desirable outcomes. furthermore, in an additional experimental treatment, we find that the mechanism is less effective when the undesirable behavior is private information, despite players having the option to voluntarily disclose such information.
