The Behavior of Unemployment Durations over the Cycle
利用收入动态面板研究中的就业日历数据，考察失业持续时间与失业率周期性波动的关系，发现失业率上升时失业持续时间延长，对已失业最久的人影响最大。
This paper examines the relationship between unemployment durations and cyclical movements in unemployment using an employment calendar constructed from recent questions in the Panel Study of Income Dynamics. We find that unemployment durations increase with the unemployment rate with the strongest effects for individuals with the longest elapsed durations. Copyright 1990 by MIT Press.
