Lessons from the U.S. Unemployment Insurance Experiments
评估了失业保险的两类改革实验：再就业奖金和求职计划。奖金实验显示经济激励影响失业金领取时长，但未证明永久奖金计划的可行性；求职计划中的服务和强化执行措施大多减少了失业金领取并改善了成本效益，但收入增加的估计不精确。
Recent social experiments have evaluated two reforms of the unemployment insurance (UI) system: reemployment bonuses and job search programs. The bonus experiments show that economic incentives affect the length of UI receipt and provide weak evidence that an earlier return to work does not decrease earnings. The experiments do not show the favorability of a permanent bonus program as they ignore its effect on the number of the claimants. The job search experiments test several more promising reforms. Nearly all of the combinations of services and increased enforcement reduce UI receipt and have favorable cost/benefit analyses. Earnings often increase, though the estimates are imprecise.
