This paper estimates spillover effects of investing in new early childhood education centers on the outcomes of children that did not attend those centers. I find positive and economically significant spillover effects in the EDI domain of communication skills and general knowledge. Furthermore, never-enrolled children have also experienced an improvement in physical health and well-being. There is no evidence of significant effects on parenting practices and reduction in behavioral problems. The evidence suggests that spillovers are driven by individual interactions instead of interaction between centers. © 2021 The Author(s).
