我们开发了一个最优学校教育投资模型，并估计：它使用了大约700个同卵双胞胎的新数据。我们估计同卵双胞胎的平均就学回报率为9%，但能力较差的个体的估计回报率似乎略高。简单的横截面估计略偏于上行。这些经验结果表明，更有能力的人获得更多的学校教育，是因为他们面临更低的学校边际成本：mg，而不是因为更高的边际收益。
We develop a model of optimal schooling investments and estimate :it using new data on approximately 700 identical twins. We estimate an average return to schooling of 9 percent for identical twins, but estimated returns appear to be slightly higher for less able individuals. Simple cross-section estimates are marginally upward biased. These empirical results imply that abler individuals attain more schooling because they face lower marginal costs of school:mg, not because of higher marginal benefits.
