Job Duration over the Business Cycle
利用美国青年纵向调查数据，发现工作持续时间的周期性取决于工人之前和之后的就业状态：从非就业到非就业的工作持续时间呈顺周期性，而跳槽的工作持续时间呈逆周期性，且起始工资差异无法解释这些模式。
Abstract Evidence from the National Longitudinal Survey of Youth (NLSY) suggests that the cyclicality of job duration depends on the worker's prior and future employment status. For example, among matches formed with previously nonemployed workers, those that end with the worker returning to nonemployment display procyclical duration. In contrast, matches that end because the worker switches to another job have countercyclical duration. Moreover, differences in starting wages do not account for these patterns.
