UNEMPLOYMENT INSURANCE AND EXPERIENCE RATING: INSURANCE VERSUS EFFICIENCY*
研究失业保险的经验评级如何影响企业裁员决策和工人保险覆盖，发现不完全经验评级能提高工人保险覆盖，并探讨福利含义。
Unemployment insurance (UI) distorts firms' layoff decisions by reducing the cost of laying off workers. To dampen this increase, it has been suggested that UI should be financed with an experience‐rated tax. Despite the fact that increasing the level of experience rating can reduce unemployment, it can reduce the insurance coverage workers receive. With high experience rating, firms may reduce their severance payments by more than the UI benefit. We build a model where competitive firms offer contracts with severance payments to risk‐averse workers. Frictions in the labor market lead to incomplete insurance. This article shows that less than full‐experience rating enables the government to increase the insurance coverage workers receive. Welfare implications are also investigated.
