Parental Preferences and Provision for Progeny
构建了一个父母在子女间分配资源的偏好模型，并用成年男性双胞胎数据估计，发现父母会为能力较差的子女提供更多资源以缩小收入差距，而非单纯追求投资回报。
This paper develops a general preference model for analyzing parental allocations of resources among their progeny. The implications fro this model for the distribution of educational resources and earnings potentials among siblings are examined. A particular version of the preference model is estimated using data on the education and earnings of adult male twins. The estimates imply that parents care about offsprings' earnings inequality and provide more (less) resources to the less (more) able than is consistent with an investment model.
