Spillover Effects between the Insured and Uninsured Unemployed
研究了失业保险金增加对未受保失业者失业时长的影响，发现存在溢出效应：保险金增加使受保者失业时间延长，但未受保者失业时间缩短，整体劳动力失业效应近乎为零。
In this paper, I consider the effect of changing the level of unemployment insurance (UI) benefits on workers who do not receive UI. I hypothesize that a spillover effect between insured and uninsured workers exists so that an increase in the UI benefits, which leads to longer durations of unemployment for insured workers, will lead to a reduction in the duration of unemployment for the uninsured. This prediction is tested using data from several March Current Population Surveys and the National Longitudinal Survey of Youth. In both samples I find that an increase in UI benefits leads to a reduction in the duration of unemployment for uninsured workers. Furthermore, using several years of state level data, I show that the estimated effect on unemployment for the entire labor force is roughly zero when I allow for the spillover effect.
