亲子信息摩擦与人力资本投资:来自实地实验的证据

Parent-Child Information Frictions and Human Capital Investment: Evidence from a Field Experiment
Journal of Political Economy · 2020 · Peter Bergman

中文摘要

本文研究了父母与子女之间的信息摩擦及其对人力资本投资的影响。我向随机抽样的父母样本每两周提供一次关于其子女未完成作业的信息。父母对子女的努力程度持有向上偏误的信念。提供信息减弱了这种偏误并提高了学生成绩。利用实验数据,我估计了父母与子女之间的说服博弈,表明处理效应源于更准确的信念和降低的监督成本。该模型的政策模拟表明,改善学校报告或向父母提供更多信息能够以低成本增加学习成效。

Abstract

This paper studies information frictions between parents and children and their effect on human capital investments. I provide biweekly information to a random sample of parents about their child’s missed assignments. Parents have upwardly biased beliefs about their child’s effort. Providing information attenuates this bias and improves student achievement. Using data from the experiment, I estimate a persuasion game between parents and their children that shows that the treatment effect is due to more accurate beliefs and reduced monitoring costs. Policy simulations from the model demonstrate that improving school reporting or providing more information to parents can increase learning at low cost.
