Long-term intergenerational persistence of human capital: an empirical analysis of four generations

Most previous studies of intergenerational transmission of human capital are restricted to two generations – parents and their children. In this study we use a Swedish data set which enables us link individual measures of lifetime earnings for three generations and data on educational attainments of four generations. We investigate to what extent estimates based on income data from two generations accurately predict earnings persistence beyond two generations. We also do a similar analysis for intergenerational persistence in educational attainments. We find two-generation studies to severely under-predict intergenerational persistence in earnings and educational attainment over three and four generations.
