Social Norms in Social Insurance
分析了保险安排、劳动供给、道德风险和欺诈如何受社会规范影响，探讨了规范改善社会福利的条件以及人们是否应被允许退出社会保险。
We analyze how insurance arrangements, labor supply, moral hazard, and outright cheating are affected by social norms. One question is under what conditions norms may improve social welfare. Another is under what conditions people should be allowed to opt out of social insurance. We introduce an informal production sector to analyze the consequences of alternative assumptions about the information available to norm enforcers. This highlights one important aspect of norms, namely, that they may compensate for the insurer’s limited information.
