This study quantified the contribution of the industry-level unemployment mismatch to the increase in the unemployment rate during 2013-2017 (0.57%p). Industry-level unemployment mismatch refers to the unemployment that occurs when job seekers’ movements across industries are hampered by labor market frictions such as wage rigidity, lack of information, and skill mismatch, etc. Although the mismatch can be defined within various dimensions, the focus was placed at the industry level as it has been found to be significant in previous overseas studies. According to the analysis, industry-level mismatch accounts for 27.7% of the observed increase in the unemployment rate during 2013-2017. Although it is impossible to investigate the specific reasons due to limitations in the research methodology, it is presumed that the rigidity of wages and working conditions are important factors based on statistics from the survey data and analysis in relevant studies. In this case, in order to reduce the unemployment rate by alleviating the industry-level mismatch, a labor market environment must be created in which wages and working conditions can be more flexibly adjusted according to relative excess demand for labor across industries.
