Abstract

We use a new sample of UK female identical twins to estimate economic returns to education. We use identical twins to control for family effects and ability bias (due to genes) and the education reported by the other twin to control for schooling measurement error. We also investigate the within-twin pair and within family correlations with observable correlates of ability. Our estimates suggest a return to schooling for females of about 7.7%.
