•This study estimates the effect of sibling sex composition on human capital and labor market outcomes using dizygotic twins.•Women born with male co-twins versus female co-twins have increased rates of high school completion and higher earnings.•No statistically distinguishable sibling sex composition effects are detected for men.
Understanding the role of the family in the production of human capital is a salient question in economics. Using a twin research design that exploits exogenous gender variation in dizygotic twins, this paper investigates the effect of sibling sex composition on schooling, earnings, and labor supply. Women born with a male co-twin have higher earnings and increased rates of high school completion than women born with a female co-twin. Men born with a female co-twin, on the other hand, have outcomes that are statistically indistinguishable from zero. Family attributes provide a limited explanation of the sex composition effect.
