기업 내 성별에 따른 임금 격차가 기업 성과에 미치는 영향

This study analyzes the effect of the gender wage gap within the company on the firm performance. Although the female worker proportion increases due to women’ improved education level and active participation in the workforce, a gender pay gap still exists. This paper expects that the gender wage gap hinder diversity and this irrational wage gap negatively affect the firm performance. To be specific, based on Human Capital Corporate Panel data, we make a more accurate wage gap proxy by measuring the difference in residuals of wage regression after controlling all individual characteristics, rather than simply using the total wage gap. The results show that as the gender wage gap within a company decreases, the firm’s performance increases. In addition, when dividing firm performance into cost and sales growth, we find that the gender wage gap does not affect the cost, but enhances firm’s sales growth. Also, we find that corporate culture does not have any additional effect on the relation between gender wage gap and firm performance. In other words, this result implies that firm performance improves when the gender wage gap decreases regardless of corporate culture. In addition, we divide the sample into two groups: gender wage gap “decrease” group and “increase” group. Then we compare the total wage gap, service years, education level, career year between men and women. As a result, there is no significant difference in personal attribute between the two samples. This additional analysis suggests that the reduction in the gender wage gap was not changed by other personal attributes.
