Intergenerational Income Mobility in the United States
利用收入动态面板研究数据，发现美国代际收入相关性至少为0.4，表明代际流动性远低于以往研究结论，对政策分析有重要参考价值。
Social scientists and policy analysts have long expressed concern about the extent of intergenerational income mobility in the United States, but remarkably little empirical evidence is available. The few existing estimates of the intergenerational correlation in income have been biased downward by measurement error, unrepresentative samples, or both. New estimates based on intergenerational data from the Panel Study of Income Dynamics imply that the intergenerational correlation in long-run income is at least 0.4, indicating dramatically less mobility than suggested by earlier research.
