Employment Adjustment and Part-Time Work: Lessons from the United States and the United Kingdom
发现兼职就业的波动是劳动市场周期中人均工时变化的主要因素，并构建了一个存量-流量框架来描述兼职就业的动态，揭示了全职与兼职之间的转换主要发生在同一雇主内部，且伴随非自愿兼职的增加。
We document that fluctuations in part-time employment play a major role in movements in hours per worker during cyclical swings in the labor market. Building on this result, we develop a stock-flow framework to describe the dynamics of part-time employment. The evolution of part-time employment is predominantly explained by cyclical changes in transitions between full-time and part-time employment. Those transitions occur overwhelmingly at the same employer, entail sizable changes in individual working hours and are associated with an increase in involuntary part-time work. Our findings provide a novel understanding of the cyclical dynamics of labor adjustment on the intensive margin.
