Parental and Child Time Investments and the Cognitive Development of Adolescents
利用收入动态面板研究的儿童发展补充数据，采用增值模型估计青少年认知生产函数，发现青少年自身的时间投入比母亲投入对认知发展影响更大。
While a large literature has focused on the impact of parental investments on child cognitive development, very little is known about the role of child's own investments alongside that of the parents. By using the Child Development Supplement of the Panel Study of Income Dynamics, we model the cognitive production function for adolescents using an augmented value-added model and adopt an estimation method that takes account of unobserved child characteristics. We find that a child's own investments made during adolescence matter more than the mother's. Our empirical results appear to be robust to several sensitivity checks.
