The Long-Run Evolution of Absolute Intergenerational Mobility
结合截面与纵向收入数据，研究了20世纪十个发达经济体绝对代际收入流动性的演变，发现20世纪下半叶流动性普遍下降，增长放缓是主因，且长期估计无需详细面板数据。
This paper combines cross-sectional and longitudinal income data to present the evolution of absolute intergenerational income mobility in ten advanced economies in the twentieth century. Absolute mobility decreased during the second half of the twentieth century in all of these countries. Increasing income inequality and decreasing growth rates have both contributed to the decrease, yet growth is the dominant contributor in most countries. We show that detailed panel data are effectively unnecessary for estimating absolute mobility over the long run.
