Abstract:

Intergenerational transmission of inequality is a central question in the social sciences. We use one trait, beauty, to infer how much parents’ physical characteristics transmit inequality across generations. Analyses of a large-scale longitudinal dataset in the United States, and a much smaller dataset of Chinese parents and children, show that increases in parents’ looks are associated with increases in their child’s looks. A large dataset of U.S. siblings shows a positive correlation of their beauty. The appropriate weighted average from the three samples shows that a one SD increase in ratings of both parents’ looks is associated with a 0.25 SD increase in their child’s. Coupling these estimates with those from large literatures measuring the impact of beauty on earnings and the intergenerational elasticity of income suggests that a one SD difference in parents’ looks is correlated with a 0.074 SD difference in their adult child’s earnings, about U.S. $2,170 annually.
