提出了一种匹配模型中的最优失业保险理论。最优的用户界面替换率是传统的贝利-切蒂替换率，它解决了保险和求职激励之间的权衡，加上一个修正项，当用户界面的增加将劳动力市场的紧张程度推向其有效水平时，这是积极的。在匹配模型中，大多数工资机制不能确保效率，因此紧密性通常是低效的。UI对紧密性的影响取决于模型：增加UI可以通过缓解激烈的工作竞争来提高紧密性，也可以通过讨价还价提高工资来降低紧密性。
This paper develops a theory of optimal unemployment insurance (UI) in matching models. The optimal UI replacement rate is the conventional Baily-Chetty replacement rate, which solves the trade-off between insurance and job-search incentives, plus a correction term, which is positive when an increase in UI pushes the labor market tightness toward its efficient level. In matching models, most wage mechanisms do not ensure efficiency, so tightness is generally inefficient. The effect of UI on tightness depends on the model: increasing UI may raise tightness by alleviating the rat race for jobs or lower tightness by increasing wages through bargaining.
