Public preschool and maternal labor supply: Evidence from the introduction of kindergartens in American public schools
Beginning in the mid-1960s, many state governments, particularly in the South and West, began to subsidize kindergartens for the first time. These initiatives generated wide variation across states over time in the supply of seats for five year olds in public schools. This paper uses the staggered timing and age-targeting of these preschool expansions to examine how the provision of universal child care through public schools affects maternal labor supply. I find that single women with five year olds but no younger children were more likely to be employed once kindergartens were available.
