숙련 편향적 기술진보와 학력별 노동자의 임금 격차: 산업 간 패널자료를 이용한 실증분석 = Skill-biased Technological Changes and Wage Inequality Across Educational Groups: An Empirical Analysis Using Panel Data of Industries

다국어 초록 (Multilingual Abstract)

Using panel data of industries, this study estimates an equation of the skill premium derived from the CES production function. We find that the Korean economy experiences skill-biased technological changes during the 1993-2008 sample period. However, the implied elasticity of substitution between skilled and unskilled workers is pretty large compared to the case of other advanced economies. The large value of the elasticity implies that skilled workerscan be replaced easily by unskilled workers and hence skill-biased technological progress has only limited impacts on the skill premium. The examination on the quantitative importance of skill-biased technological yields the result consistent with this implication: the supply index is a more dominant factor than skill-biased technological progress in shaping the observed trend of skill premium over the past three decades in Korea. Finally, we find no evidencethat skill premium is more concentrated on younger age cohorts. The current result implies that skill-biased technological change developed since 1990s has only limited impact on college premium.
