The Effect of Early-Childhood Education on Social Preferences
研究随机分配3-4岁儿童到全日制幼儿园、育儿项目或对照组，6-8岁时通过激励实验测量社会偏好，发现幼儿教育对社会偏好有显著因果影响。
We present results from the first study to examine the causal impact of early childhood education on the social preferences of children. We compare children who, at 3-4 years old, were randomized into either a full-time preschool, a parenting program, or a control group. We returned to the children when they reached 6-8 years of age and conducted a series of incentivized experiments to elicit their social preferences. We find that early childhood education has a strong causal impact on social preferences. Our findings highlight the importance of taking a broad perspective when designing and evaluating early childhood educational programs.
