Local Distortions in Parental Beliefs over Child Skill
利用1999年早期儿童纵向研究数据，发现父母对孩子认知技能的判断受同校其他孩子水平影响，学校平均技能低则高估孩子，反之亦然。教师评价也有类似偏差，进而影响父母投资。
Using data from the Early Childhood Longitudinal Study–Kindergarten Class of 1999, we show that parental beliefs about a child’s cognitive skill relative to children of the same age are distorted by a child’s cognitive skill relative to children in the same school. Parents of children attending schools with low (high) average skills tend to believe their child is higher (lower) in the overall skill distribution than they actually are. Teacher evaluations of child skill also exhibit local distortions, providing a channel through which parental biases might arise. Finally, we relate parental beliefs and investment, providing insight on how local distortions may impact the skill distribution.
