Abstract

Labor market outcomes demonstrate considerable variation between and within skill groups. We construct a general equilibrium model with incomplete markets and exogenous differences that matches these facts. We study the role of exogenous heterogeneity in choosing the optimal replacement rate and the maximum benefit for an unemployment insurance (UI) system. The optimal average replacement rate is 27%, compared to 0% in a model without exogenous heterogeneity. The relatively generous choice is due to the redistributive role of UI, which is a manifestation of two elements. First, workers who are unemployed more often receive positive net transfers from the UI system because they draw resources more frequently. Second, the existence of a cap on benefits makes UI progressive. Our main result holds in the presence of a generous progressive taxation system.

论事前异质性的失业保险规定

摘要

劳动力市场的结果表明，技能组之间和内部的差异很大。我们构建了一个具有不完全市场和与这些事实相匹配的外生差异的一般均衡模型。我们研究了外源异质性在为失业保险（UI）系统选择最佳替代率和最大收益方面的作用。最佳平均替换率为27％，而没有外源异质性的模型则为0％。相对大方的选择是由于UI的重新分配作用，它是两个元素的体现。首先，失业的工人更经常从UI系统获得积极的净转移支付，因为他们更频繁地提取资源。第二，利益上限的存在使UI不断进步。
