Abstract: | Complementing prior research on income and educational mobility, we examine the intergenerational transmission of cognitive
abilities. We find that individuals’ cognitive skills are positively related to their parents’ abilities, despite controlling
for educational attainment and family background. Differentiating between mothers’ and fathers’ IQ transmission, we find different
effects on the cognition of sons and daughters. Cognitive skills that are based on past learning are more strongly transmitted
between generations than skills that are related to innate abilities. Our findings are not compatible with a pure genetic
model but rather point to the importance of parental investments for children’s cognitive outcomes. |
