中文摘要
本文构建了一个框架, 用以处理家长报告的儿童非认知技能测量中的污染问题。我们估计了一个儿童与家长技能共同演化的动态模型, 并借助教师和访员提供的信息来应对家长报告测量的污染。该模型还使我们能够考察母亲与父亲在儿童技能演化中的相对重要性。我们的发现表明, 忽视污染会显著低估母亲非认知技能在儿童非认知技能演化中的作用。此外, 我们发现有证据表明, 儿童技能对母亲的反馈效应强于对父亲的反馈效应。模拟练习展示了污染如何可能扭曲对早期儿童政策的评估, 从而凸显了稳健测量方法的重要性。
Abstract
This paper develops a framework to address issues of contamination in parent‐reported measures of child noncognitive skills. We estimate a dynamic model in which child and parental skills evolve jointly and leverage information provided by teachers and interviewers to deal with contamination of parent‐reported measures. The model also allows us to examine the relative importance of mothers and fathers in the evolution of child skills. Our findings reveal that ignoring contamination significantly underestimates the role of maternal non‐cognitive skills in the evolution of child noncognitive skills. Additionally, we find evidence of stronger feedback effects from child skills to mothers than fathers. Simulation exercises demonstrate how contamination can distort evaluations of early childhood policies, underscoring the importance of robust measurement approaches.
