The Long-Term Effects of UI Extensions on Employment
利用断点回归设计，分析失业保险延长期限对就业的长期影响，并推导包含反复失业的福利公式。
The majority of papers analyzing the employment effects of unemployment insurance (UI) benefit durations focus on the duration of the first unemployment spell. In this paper, we make two contributions. First, we use a regression discontinuity design to analyze the long-term effects of extensions in UI durations. These estimates differ from standard estimates in that they incorporate differences in UI benefit receipt and employment due to recurrent unemployment spells. Second, we derive a welfare formula of UI extensions that incorporates recurrent nonemployment spells.
