Short- and medium-run impacts of preschool education: evidence from state pre-K programs
摘要
This paper studies the effects of state preschool programs on grade progression, child development, and health outcomes from ages 5 to 15 in the United States. Leveraging variation in the timing of pre-K program implementation across states and using data from state legislatures and two national surveys, I estimate the dynamic reduced-form impacts of a large group of pre-K programs. The findings show that pre-K significantly reduces grade retention, particularly for children from low socioeconomic backgrounds, with no significant differences between targeted and universal pre-K programs. There is suggestive evidence of short-run improvements in developmental and behavioral outcomes, alongside a temporary increase in illness-related missed school days, but no significant effects on overall health. These results highlight the lasting academic benefits of early childhood education, especially for disadvantaged children.
