In this paper, we estimate the wage premium of English skills in the Korean labor market using Korean Labor and Income Panel Study(KLIPS) data. In a simple OLS model, we find that people with some English skills in terms of self evaluation or job requirement earn 30% more than those who do not have English skills. But in a small sample of relatively young people, higher English lest scores do not raise earnings. When we add SAT scores in the wage equation, there is no wage premium of English skills, and in the IV estimation, we find no "English premium". These results consistently imply that while there is a large wage premium of English skills in the Korean labor market, it reflects unobservable ability for the most part. Meanwhile some of the regression results favor human capital theory over screening theory as an explanation of the nature of the wage premium of English skills.

This study aimed to provide important information on vocational education and employment policy for the disabled by analyzing the relationship between disabled wage workers' occupational ability and job quality. For this purpose, the relationship between job competence and employment quality was theoretically examined and empirically analyzed based on human capital theory, screening theory, and job competition theory. The empirical analysis used data on 975 disabled wage workers with the use of the data of the 8th Panel Survey of Employment for the Disabled(2015). As a result of the empirical study, it was found that the occupational ability of the disabled workers is an important factor in determining Wage, job status, job satisfaction, which constitute the quality of employment. This result indicates that job quality can be improved by ameliorating disabled people's occupational ability. Accordingly, this study proposed that there might be a need to extend customized education and educational facilities for improving disabled people's occupational ability.
