Coordinated Work Schedules and the Gender Wage Gap

Using U.S. time diary data we construct occupation-level measures of coordinated work schedules based on the concentration of hours worked during peak hours of the day. A higher degree of coordination is associated with higher wages but also a larger gender wage gap. In the data women with children allocate more time to household care and are penalized by missing work during peak hours. An equilibrium model with these key elements generates a gender wage gap of 6.6 percent or approximately 30 percent of the wage gap observed among married men and women with children. If the need for coordination is equalized across occupations and set to a relatively low value (i.e. Health care support), the gender gap would fall by more than half to 2.7 percent.
