Abstract
This paper investigates the extent to which initial conditions in the labor market influence the progress of job polarization in Korea. In particular, we compare the following two competing hypotheses: a specialization hypothesis and an inter-industry wage differentials hypothesis. Our findings indicate that job polarization is pronounced in industries that have historically relied on routine tasks and have experienced a significant increase in ICT capital intensity between 2000 and 2019. By contrast, initial inter-industry wage differentials are not associated with job polarization in Korea during the same period.
