Abstract

To date the analysis on the wage penalty faced by over-educated doctorate holders is surprisingly scarce. Being focused on college graduates, the existing literature has primarily tended to adopt a standard ordinary least squares regression technique that allows measuring the impact of over-education on the conditional mean of the wage distribution. This paper aims to fill this gap, not only by assessing the extent to which the prevalence of over-educated doctorate holders in science, technology, engineering, and mathematics (STEM) fields in South Korea is distributed across the wage distribution, but also by examining the extent to which their wage penalty relative to what they could have earned in a job corresponding to their level of education may have varied across the wage distribution. The main findings reveal that there is no evidence to support the notion that over-education and ability are inversely related among STEM doctorate holders in Korea. Based on the empirical evidence, this article suggests that it is an oversimplification to characterise both the incidence and the wage effects of over-education as merely reflecting lower-ability levels, at least in the Korean context.

工资分配中教育程度过高的工资惩罚:韩国STEM博士的案例研究
迄今为止,对学历过高的博士所面临的工资惩罚的分析少得惊人。由于关注的是大学毕业生,现有文献主要倾向于采用标准的普通最小二乘回归技术,该技术可以测量过度教育对工资分布条件均值的影响。本文旨在填补这一空白,不仅通过评估韩国科学、技术、工程和数学(STEM)领域受教育程度过高的博士学位持有者的普遍程度在工资分布中的分布程度,而且还通过研究他们的工资惩罚相对于他们在与其教育水平相对应的工作中可能获得的收入在工资分布中的变化程度。主要研究结果显示,没有证据支持韩国STEM博士的过度教育与能力成反比的观点。基于经验证据,本文认为,将过度教育的发生率和工资影响描述为仅仅反映较低的能力水平是过于简单化的,至少在韩国的背景下是这样。
