Education, Birth Order and Family Size
提出一个研究父母在子女出生顺序偏好和人力资本成本差异下投资行为的框架，利用丹麦行政数据验证了家庭规模扩大降低平均教育水平，且小家庭子女的人力资本优于大家庭。
Abstract This article introduces a framework to study parental investments in the presence of birth order preferences and/or human capital cost differentials across children. The framework yields canonical models as special cases and delivers sharp testable predictions concerning how parental investments respond to an exogenous change in family size in the presence of birth order effects. These predictions characterize a generalised quantity–quality trade-off. Danish administrative data confirm our theory’s predictions. We find that for any given parity, the human capital profile of children in smaller families dominates that of large families, and that the average child’s education decreases as family size increases, even after taking birth order effects into consideration.
