CHANGING ROLES OF ABILITY AND EDUCATION IN U.S. INTERGENERATIONAL MOBILITY
利用1979和1997年青年纵向调查数据，发现能力对代际经济地位传递的作用在最新一代中显著减弱，而教育的作用则大幅增强，且性别差异明显。
Using data on young adults from the 1979 and 1997 National Longitudinal Survey of Youth, we investigate the changing roles of ability and education in the transmission of economic status across generations. We find that ability plays a substantially diminished role for the most recent cohort whereas education plays a much larger role. The first finding results primarily from a smaller effect of children's ability on status, the second from an increased correlation between parental status and educational attainment. A replication of the analysis by gender reveals that the changes in the role of ability are largely driven by men whereas the changes in education's role are largely driven by women.
