Rich Dad, Smart Dad: Decomposing the Intergenerational Transmission of Income
构建模型将代际收入弹性分解为父亲财务资源的因果效应、人力资本的机械传递以及人力资本在父亲永久收入决定中的作用，利用瑞典父子数据发现仅小部分弹性可归因于财务资源。
We construct a simple model, consistent with Becker and Tomes, that decomposes the intergenerational income elasticity into the causal effect of financial resources, the mechanistic transmission of human capital, and the role that human capital plays in the determination of fathers' permanent incomes. We show how a particular set of instrumental variables could separately identify the money and human capital transmission effects. Using data from a 35 percent sample of Swedish sons and their fathers, we show that only a minority of the intergenerational income elasticity can be plausibly attributed to the causal effect of fathers' financial resources.
