Qualifying for Unemployment Insurance: An Empirical Analysis
利用加拿大失业保险系统的一次意外实验，分析提高资格要求（需工作周数增加最多4周）对就业持续时间的影响，通过比较1990年实验年份与前一年不同地区的就业退出风险率来识别效应。
Little is known about the effect of unemployment insurance (UI) on employment durations. In this paper we take advantage of a unique accidental experiment in the Canadian UI system which created an exogenous increase in the entrance requirement (the number of weeks an individual must work to qualify for benefits) of up to 4 weeks in some regions. We identify the effects of this increase primarily by comparing the hazard rate out of employment for the experimental year, 1990, with that for the preceding year in regions where other parameters of the UI system do not change.
