本文的目的是测量的因果关系的影响，教育收入使用的双胞胎在日本编制了广泛的社会经济信息的大型数据集。最近在中国进行的研究表明，与西方国家的情况相反，在估计教育回报时，能力偏见很大。有人认为，中国的低回报率部分是由于竞争和应试教育制度，这是类似于日本的制度。本研究的实证结果表明，即使修正了自我报告的能力偏差和测量误差，以日本同卵双胞胎为样本的教育回报率估计值仍为9.3%。我们的研究结果表明，传统的OLS估计在日本并没有受到潜在偏差的严重污染。
The objective of this article is to measure the causal effect of education on earnings using a large dataset of twins compiled in Japan with wide-ranging socioeconomic information. Recent research conducted in China showed that, contrary to the case in Western countries, ability bias is large in estimating the return to education. It is argued that the low rate of return in China is in part due to the competitive and exam-oriented education system, which is similar to the system in Japan. The empirical results in our study show that the estimated rate of return to education using the sample of identical twins in Japan is 9.3 percent even after omitted ability bias and measurement errors in self-reported schooling were corrected. Our findings suggest that the conventional OLS estimate is not significantly contaminated by potential biases in Japan.
