中文摘要
我们刻画了美国不同代际间劳动收入、其他收入来源与消费的横截面不平等的共同演变。为解释横截面离散程度，我们估计了一个代际持续性模型，分别识别出父母因素与个体特异性生命周期成分各自的影响。我们发现，在收入、消费和储蓄行为以及婚姻匹配模式方面均存在家庭持续性的证据。然而，个体特异性异质性对横截面不平等的定量贡献显著大于父母效应。我们的估计表明，代际持续性尚不足以随着时间推移和代际更替引发不平等的进一步大幅增加。
Abstract
We characterize the joint evolution of cross-sectional inequality in earnings, other sources of income and consumption across generations in the U.S. To account for cross-sectional dispersion, we estimate a model of intergenerational persistence and separately identify the influences of parental factors and of idiosyncratic life-cycle components. We find evidence of family persistence in earnings, consumption and saving behaviours, and marital sorting patterns. However, the quantitative contribution of idiosyncratic heterogeneity to cross-sectional inequality is significantly larger than parental effects. Our estimates imply that intergenerational persistence is not high enough to induce further large increases in inequality over time and across generations.
