An Empirical Study on the Differences and Discrimination in Gender Pension Gap

Abstract

This study empirically examines whether the gender pension gap in the National Pension System stems from ‘difference’ in the attributes of men and women or from unequal structural ‘discrimination’ in the labor market and family. To this end, OLS estimation and Oaxaca-Blinder decomposition analysis were conducted on old-age pension recipients using KReIS 8th data. The analysis attributed about 53% of the gender pension gap to differences in attributes between men and women, and about 47% to structural discrimination that is not explained by individual, gender, and labor market characteristics. A remarkable result was that ‘with or without children’ accounted for the highest proportion of discrimination in the gender pension gap, which clearly suggests that the burden of care passed on to women is reproducing the gap in retirement income security. These results show that the labor market is still unevenly gendered, and that the gender-based role division within the family is such that most family care responsibilities are transferred to women. Therefore, simplistic measures such as accumulating human capital, promoting women's employment, and increasing pension coverage and benefit levels will only marginally reduce the gender pension gap. Accordingly, there is a need for long-term efforts to eradicate deep-rooted discrimination in the labor market and family. As a more immediate measure, a new care credit system can be considered to formally recognize the social value of family care.
