Abstract

This paper examines the gender pay gap among doctorate holders in Korea to understand the determinants of this gap and control of its variation. A particular focus of this study is to seek to infer the extent to which this pay gap is the consequence of gender-based disparate treatment. The main results indicate that there is a sizeable gender pay gap even among workers with doctorate degrees, that is, very highly educated workers. Moreover, this gender pay gap cannot be largely explained by gender differences in characteristics, indicating the existence of discrimination against female doctorate holders in the Korean labor market.

본 연구는 박사학위 소지자들을 대상으로 성별 임금격차와 그 원인에 대해 분석하였다. 국내 박사인력을 대상으로 하는 표본조사인 박사인력활동조사를 이용하여 박사학위 소지자들의 성별 임금격차 수준을 우선 식별하고, 임금격차에 대한 정확한 실태 파악을 위해 Oaxaca류의 임금격차 분해 모형을 이용하여 성별 임금격차를 두 집단의 인적특성 차이에 기인하는 임금차이와 임금방정식의 추정계수 차이로 인해 발생하는 임금차별로 분해하였다. 분석 결과 임금격차 중 임금분해 모형으로 설명이 불가능한 임금방정식의 구조적 차이로 인한 임금차별의 비중이 약 38~43% 수준으로 나타났으며, 이는 박사학위 소지자들의 성별 임금격차에도 노동시장에서의 차별에 관한 문제의 중요성이 크다는 것을 암시한다.
