The Dynastic Benefits of Early-Childhood Education: Participant Benefits and Family Spillovers
基于HighScope佩里学前项目长达中年的追踪数据，评估高质量早期儿童教育的成本收益比，并量化对参与者子女和兄弟姐妹的溢出效应，发现总收益成本比达7.5。
We demonstrate the social efficiency of investing in high-quality early-childhood education using newly collected data from the HighScope Perry Preschool Project. The data analyzed are the longest follow-up of any randomized early-childhood education program. Annual observations of participant outcomes up to midlife allow us to provide a cost-benefit analysis without relying on forecasts. Adult outcomes on the participants’ children and siblings allow us to quantify spillover benefits. The program generates a benefit-cost ratio of 6.0 (p-value = .03). Spillover benefits increase this ratio to 7.5 (p-value = .00).
