School calendars,child care availability and maternal employment

A year-round calendar redistributes schools days around the year. This paper studies how this redistribution of school days, and therefore child care days available through school, affects maternal employment. The presence of year-round calendars in a district could be correlated with other district level attributes that might affect female employment rates. I therefore use a differencing method that compares the influence of district year-round enrollment on the employment rates of women with school-aged children relative to women whose eldest child is pre-school-aged. Unobserved district factors should affect employment rates of women with school-aged and pre-school-aged children similarly, yet only women with school-aged children should be directly impacted by school calendar. I find that redistributing child care days available through school into shorter intervals over time negatively impacts maternal employment. Among those women with school-aged children, those also having pre-school-aged children have the hardest time adjusting to differences in existing availability.
