面向失业者的保险合约菜单

A Menu of Insurance Contracts for the Unemployed
Review of Economic Studies · 2021 · Régis Barnichon、Yanos Zylberberg

中文摘要

失业保险(UI)项目传统上采取向求职者提供单一保险合约的形式。本文表明,在存在逆向选择和道德风险的情况下,提供合约菜单可以改善福利。当保险合约由(1)失业保险金和(2)失业之初支付的遣散费组成时,在一个相当于单交叉条件的条件下,提供失业保险金与遣散费之比不同的合约是最优的:对失业保险需求越高的求职者,产生道德风险的倾向应越低。在这一设定下,合约菜单使规划者能够以失业保险金较为丰厚的合约吸引保险需求较高的求职者,同时以另一项遣散费较高但失业保险金较少的合约吸引最容易产生道德风险的求职者。我们提出一种简单的充分统计量方法,以利用数据检验这一单交叉条件。

Abstract

Abstract Unemployment insurance (UI) programs traditionally take the form of a single insurance contract offered to job seekers. In this work, we show that offering a menu of contracts can be welfare improving in the presence of adverse selection and moral hazard. When insurance contracts are composed of (1) a UI payment and (2) a severance payment paid at the onset of unemployment, offering contracts with different ratios of UI benefits to severance payment is optimal under the equivalent of a single-crossing condition: job seekers in higher need of unemployment insurance should be less prone to moral hazard. In that setting, a menu allows the planner to attract job seekers with a high need for insurance in a contract with generous UI benefits, and to attract job seekers most prone to moral hazard in a separate contract with a large severance payment but little unemployment insurance. We propose a simple sufficient statistics approach to test the single-crossing condition in the data.
