An alternative measure of intergenerational income mobility based on a random coefficient model
提出一种基于随机系数模型的代际收入流动性新度量，允许家庭间流动性因未观测特征而异，发现代际收入持续性通常强于传统弹性度量。
SUMMARY We propose an alternative measure of the degree to which income status is transmitted from one generation to another. Our indicator of intergenerational income mobility is based on a random coefficient model, which allows for variation in intergenerational mobility across families due to multiplicative unobserved family‐specific characteristics. This alternative measure suggests that intergenerational income persistence is typically stronger than when intergenerational income mobility is measured using the standard elasticity of sons' income with respect to fathers' income.
