Long-Term Intergenerational Persistence of Human Capital
利用瑞典四代人的教育数据和三代人的终生收入数据，发现基于两代人的估计严重低估了长期代际持续性，长期社会流动性比以往认为的低得多，并将额外持续性归因于“王朝人力资本”。
Most previous studies of intergenerational transmission of human capital are restricted to two generations: how parents influence their children. In this study, we use a Swedish data set that links individual measures of lifetime earnings for three generations and data on educational attainment for four generations. We find that estimates obtained from data on two generations severely underestimate long-run intergenerational persistence in both labor earnings and educational attainments. Long-run social mobility is hence much lower than previously thought. We attribute this additional persistence to "dynastic human capital"—the influence on human capital of more distant family members than parents.
