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.application/pdfen-AU© 2020 The authorshttps://creativecommons.org/licenses/by-nc/4.0/202010.1086/7068582022-09-25
