The social stratification literature is inconclusive about whether there is a direct effect of grandparent resources on grandchildren’s educational outcomes net of parental characteristics. Some of this heterogeneity may be due to differences in omitted variable bias at the parental level. Our article accounts for a more extensive set of parent characteristics and explores the mediating role of parental cognitive ability in more detail. It further tackles methodological challenges (treatmentinduced mediator–outcome confounders, treatment–mediator interaction) in assessing any direct influences of grandparents by using a regression-with-residuals approach. Using the 1970 British Cohort Study, our results show that the direct effect of grandparent education on grandchildren’s verbal and numerical ability is small and statistically nonsignificant. Parental cognitive ability alone can account for more than two-thirds (numerical ability) or half (verbal ability) of the overall grandparent effect. These findings stress the importance of cognitive ability for intergenerational social mobility processes.

It's All about the Parents: Inequality Transmission across Three Generations in Sweden

A recent literature studies the role of grandparents in status transmission. Results have been mixed, and theoretical contributions highlight biases that complicate the interpretation of these studies. We use newly harmonized income tax records on more than 700,000 Swedish lineages to establish four empirical facts. First, a model that includes both mothers and fathers and takes a multidimensional view of stratification reduces the residual three-generation association in our population to a trivial size. Second, data on fathers’ cognitive ability show that even extensive controls for standard socioeconomic variables fail to remove omitted variable bias. Third, the common finding that grandparents compensate poor parental resources can be attributed to greater difficulty of observing parent status accurately at the lower end of the distribution. Fourth, the lower the data quality, and the less detailed the model, the greater is the size of the estimated grandparent coefficient. Future work on multigenerational mobility should pay less attention to the size and significance of this association, which depends heavily on arbitrary sample and specification characteristics, and go on to establish a set of more robust descriptive facts.
