Correlation of Brothers' Earnings and Intergenerational Transmission
利用丹麦父子三人的数据，在统一框架下估计兄弟收入相关性和代际传递，发现代际效应解释了72%的兄弟相关性，且兄弟相关性在生命周期中呈U形变化。
We estimate sibling correlations and intergenerational transmission of life cycle earnings within a unified framework that nests previous models. Using data on the Danish population of father/first-son/second-son triads we find that intergenerational effects account for 72% of sibling correlations. This share is higher than in previous studies because we allow for heterogeneous intergenerational transmission between families. For the first time, we show significant U-shaped life cycle variation in sibling correlations, consistent with human capital models. Estimates of intergenerational mobility are of greater value than previously thought for understanding the role of the family in explaining earnings inequality.
