许多人一直对在日本读研究生的经济价值持怀疑态度。然而，很少有实证研究对这一问题进行分析。本文估算了日本研究生教育的私人内部收益率，并评估了日本研究生工资溢价。特别是，该研究通过分析毕业后继续为同一雇主工作的工人的年龄工资情况，说明了企业和机构的工资系统对研究生毕业生的偏爱程度超过大学毕业生。通过对大学学历和研究生学历的年龄工资情况的比较发现，无论是男性还是女性，研究生学历的人一生工资收入都高于大学学历的人。随着年龄的增长，研究生毕业生的工资继续上涨，这扩大了他们与大学毕业生的工资差距。硕士学位的内部回报率男性为11.4%，女性为10.1%，博士学位的内部回报率男性为5.9%，女性为5.7%。因此，本文显示了研究生的工资明显高于大学毕业生。
Many people have been skeptical about the economic value of going to graduate school in Japan. However, there are few empirical studies to analyze this issue. This paper estimates the private internal rate of return to postgraduate education and assesses the postgraduate wage premium in Japan. In particular, the study illustrates how much the payroll systems of companies and institutions favor postgraduate graduates over college graduates by analyzing the age-wage profiles of workers who continuously work for the same employers after they graduate. The comparison of the age-wage profiles of college degree holders and postgraduate degree holders reveals that the lifetime wage income is higher among those with postgraduate degrees than among those who have college degrees both for males and females. The wages of postgraduate graduates continue to rise as they get older, which widens the wage gap with college graduates. The internal rates of return to master’s degrees are 11.4% for males and 10.1% for females, while the ones to Ph.Ds are 5.9% for males and 5.7% for females. The paper therefore shows the significant postgraduate wage premium over college graduates.
