This article concerns the incidence and dynamics of dual-job holding and its link to job mobility. We present evidence from US data on patterns of dual-job holding, hours changes, and job mobility. We find that workers move into and out of second jobs frequently, these movements are associated with large changes in work hours, and that hours constraints may prompt workers to take second jobs. Second, we 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.
