Abstract
There is massive cross-sectional evidence that children of more educated parents
outperform their schoolmates on tests, grade repetition and in educational attainment.
However, evidence for causal interpretation of this association is weak. Within a rich
census level data set for Norway, we examine the causal relationship using two
approaches for identification: cousins with twin parents and adopted children. In line
with most of the literature, we find no effect of mothers’ education on children’s
school performance using the children-of-twins approach. However, for adopted
children, mother’s education has a positive effect, but only a third of the size of the
effect found in biological relationships in adopting families. Carefully tracking the
work experience of parents during offspring childhood, we find no support for the
hypothesis that the small causal effects of parental education can be explained by
detrimental effects of higher labour force participation among more educated mothers.
