성별 고용형태별 임금격차 현황과 요인 분해

In Korea, wage level of irregular female workers is 52.4% of regular male workers. It is some possibility that irregular female workers are faced multiple discrimination based on sex and employment pattern because of the spread of gender discrimination or employment pattern discrimination in labor market. Until now most of papers have been discussing on pay gap and decomposition of wage gap due to gender or employment pattern respectively . Thus, even though average wage of irregular female worker is 52.4% of that of regular male worker, there are few paper to analyse the wage gap based on both gender and employment pattern, the differences and similarity between gender pay gap and employment pattern pay gap. This paper estimates wage equations and attempts decomposition of wage gap based on gender and employment pattern respectively. In this paper the wage gap is measured on the basis of hourly wages. As the results of this analysis using Oaxaca and Ransom’s two-fold decomposition method, 44.9% of gender gap is an unexplained part due to discrimination etc. On the other hand, 18.9% of total pay gap between regular and irregular worker is due to discrimination. This means that the parts of gender pay gap due to discrimination are ar larger than that of pay gap between regular worker and irregular worker. According to this results, to improve low wage of irregular female workers, the measures to eliminate gender discrimination in labor market should be implemented effectively.
