    Intergenerational Mobility Trends and the Changing Role of Female Labor

    Full text link
    Using harmonized administrative data from Scandinavia, we find that intergenerational rank associations in income have increased uniformly across Sweden, Denmark, and Norway for cohorts born between 1951 and 1979. Splitting these trends by gender, we find that father-son mobility has been stable, while family correlations for mothers and daughters trend upward. Similar patterns appear in US survey data, albeit with slightly different timing. Finally, based on evidence from records on occupations and educational attainments, we argue that the observed decline in intergenerational mobility is consistent with female skills becoming increasingly valued in the labor market.Comment: 67 page
