Preschoolers Enrolled and Mothers at Work? The Effects of Universal Prekindergarten
利用普查数据和基于生日的资格截止点，采用断点回归方法，研究了普及学前班对学前入学率和母亲劳动供给的影响，发现入学率提高约14%，但对多数女性劳动供给影响很小。
Three states recently introduced universal prekindergarten programs offering free preschool to all age-eligible children; policy makers in many other states are promoting similar programs. Using restricted-access data from the Census, together with birthday-based eligibility cutoffs, I employ a regression discontinuity framework to estimate the effects of universal pre-K availability on overall preschool enrollment and maternal labor supply. Universal pre-K availability increases statewide preschool enrollment by about 14% but has little effect on the labor supply of most women. (c) 2010 by The University of Chicago. All rights reserved.
