The Dynamics of Dual Job Holding and Job Mobility
利用美国数据研究双重工作持有与工作流动的关系，发现工人频繁进出第二份工作，伴随工时大幅变化，工时限制可能促使工人从事第二份工作，并提出了一个随机动态模型。
This article concerns dual job holding and its link to job mobility. The authors present evidence from U.S. data on patterns of dual job holding, hours changes, and job mobility. They find that workers move into and out of second jobs frequently, that these movements are associated with large changes in work hours, and that hours constraints may prompt workers to take second jobs. Second, the authors review theories of dual job holding and present a stochastic dynamic model of dual job holding and job mobility in which decisions to take second jobs and/or change main jobs are made simultaneously.
