Endowments and the Allocation of Schooling in the Family and in the Marriage Market: The Twins Experiment
利用同卵和异卵双胞胎数据，识别个体特定禀赋的变异程度以及家庭和婚姻市场中教育对禀赋的反应，发现27%的收入方差和42%的肥胖方差源于个体禀赋差异，且教育分配强化了特定禀赋。
The authors show how comparisons between the within-twin correlations of human capital outcomes across identical and nonidentical twins can be used to identify the variability in the individual-specific component of endowments and the responsiveness of schooling to individual-specific endowments in the family and in the marriage market even when schooling is measured with error. Estimates from two twins samples indicate that 27 (42) percent of the variance in log earnings (obesity) is due to variability in individual-specific endowments, allocations of schooling reinforce specific endowments, and individual-specific earnings endowments of men and their wives' schooling are negatively associated.
