　　内容摘要：

　　This study examines the effect of work schedule regularity on cashier productivity. The literature suggests that regular work schedule is associated with better rest and healthier lifestyle, and thus higher employee productivity. Higher productivity, in turn, helps to address the trade-off associated with increasing work schedule regularity: while employee well-being and income can be improved, employers will suffer from increased costs and reduced efficiency in the industry sectors where demand is quite volatile. Using scanner data from a retail chain in a northwestern state of the U.S., we find consistent work hour (hour of the day) and consistent work day (day of the week) improve cashier productivity by 0.94% and 1.64%, respectively. However, the effects of the two types of schedule regularity are not complementary. The combined effect is less than the sum of individual effects. We also find clopening (a case where an employee closes the store at night and then comes back to open the store the next morning) sharply decreases cashier productivity by 4.89%. Additionally, work experience weakens the positive effects of work schedule regularity on cashier productivity, probably because experienced cashiers already developed strategies to cope with schedule irregularity. The findings collectively provide some empirical evidence for retailers to fine-tune work schedule and we discuss the implications of our findings in detail.
