Recover Overnight? Work Interruption and Worker Productivity
研究发现，工人经历机器故障导致的工作中断后，次日生产力下降3.3个百分点，可能源于负面情绪、操作谨慎或技能生疏，对管理者理解中断影响有参考价值。
This paper investigates the effect of work interruption on workers’ subsequent productivity. We employ a data set of individual productivity and machine conditions, in which each worker faces the chance, on a daily basis, that her machine will break down randomly. Our analysis finds that compared to a workday with smooth production, experiencing a machine breakdown is associated with a 3.3 percentage point decline in the worker’s productivity the following day. We discuss possible explanations for the observed effect, including negative emotions, increased cautiousness in operating the machine, and proficiency loss. Our findings shed light on the importance of understanding and managing interruptions in the workplace, and contribute to a growing literature on the determinants of productivity at the micro level.
