We present a model in which human capital investments occur over the life cycle and across generations, à la Becker and Tomes. The human capital technology features multiple stages of childhood investments, college, and life cycle accumulation. The model can explain a wide range of intergenerational relationships while remaining empirically consistent with cross-sectional inequality. Much of the latter is determined by early investments in children, so that borrowing constraints faced by young parents are important for understanding the persistence of economic status across generations. Education subsidies, especially early on, can significantly reduce the intergenerational persistence of economic status.
我们提出了一个模型,其中人力资本投资贯穿生命周期并跨越代际,类似于贝克尔和托姆斯的模型。人力资本技术具有儿童投资、大学教育和生命周期积累的多个阶段。该模型可以解释广泛的代际关系,同时在实证上与横截面不平等保持一致。后者很大程度上由对儿童的早期投资决定,因此年轻父母面临的借贷约束对于理解经济地位在代际间的持续性很重要。教育补贴,尤其是早期的补贴,可以显著降低经济地位的代际持续性。
