There has long been interest in the extent to which effects of social stratification extend and persist across generations. We take a novel approach to this question by asking whether birth order and sibling group size in the parental generation influences the educational attainment of their...

For decades, geneticists and social scientists have relied on sibling correlations as indicative of the effects of genes and environment on behavioral traits and socioeconomic outcomes. The current paper advances this line of inquiry by exploring sibling similarity across a variety of...

The stylized fact that individuals who come from families with more children are disadvantaged in the schooling process has been one of the most robust effects in human capital and stratification research over the last few decades. For example, Featherman and Hauser (1978: 242-243) estimate that...
