Patterns of Intergenerational Mobility in Income and Earnings
利用美国全国纵向调查的亲子配对数据,发现父母收入仅能解释子女收入变动的9%至11%,收入比总收入流动性更强,且女儿差异最显著。家庭背景特征额外增加3至5个百分点的解释力。
This paper characterizes the patterns of intergenerational mobility in the United States using data for matched parent/child pairs from the National Longitudinal Surveys. In general, what is found is far from the extremes of either perfect mobility or perfect immobility. Parents' log income explains only about 9 percent to 11 percent of the variation in children's log incomes. Earnings exhibit more mobility than does total income, and the difference is most striking for daughters. The paper also identifies the influence of family background characteristics on mobility. The addition of these background variables adds another 3 to 5 percent age points to the R2 in the intergenerational earnings and income regressions. Copyright 1992 by MIT Press.
