In this paper, I conduct a novel comparison of intergenerational income mobility in Denmark and the United States, based on high‐quality administrative data for both countries. The results confirm that the United States is substantially less mobile than Denmark, but they also show that the differences in mobility are smaller than previously reported. Mobility differences are larger for family income than individual income. When the individual incomes of children are considered, mobility differences are smaller for daughters than for sons. I also show that the estimated intergenerational elasticity of income for Denmark is quite robust to whether taxes or public transfers are included in the income measure.

丹麦和美国的代际收入流动性*

在本文中，我基于两国的高质量行政数据，对丹麦和美国的代际收入流动性进行了新颖的比较。结果证实，美国的流动性大大少于丹麦，但它们也显示出流动性的差异要小于先前的报道。家庭收入的流动差异大于个人收入。考虑到儿童的个人收入，女儿的流动性差异要比儿子的流动性差异小。我还表明，估计丹麦的代际收入弹性对于收入计量中是否包括税收或公共转移支付是相当有力的。
