Effects of New Technology Adoption in Korea: Implications for Growth, Employment, and Inequality
한국은행은 새로운 기술과 노동시장 마찰의 상호작용이 고용, 양극화, 불평등에 미치는 영향을 분석한 보고서를 발표하였다.
This paper studies how new technologies interact with labor-market frictions to shape aggregate and distributional outcomes in a Korean context. We build a quantitative heterogeneous-agent general equilibrium model with incomplete markets in which households choose between working fixed hours and investing time in learning, subject to convex human-capital adjustment costs. Firms combine capital and effective labor and face quadratic costs of adjusting employment. In the benchmark polarized scenario, long-run output, consumption, and investment all increase, but aggregate employment falls as workers reallocate time from market work toward human-capital accumulation. This reallocation generates endogenous job polarization across skill groups and raises income and consumption inequality. Labor-market frictions are crucial for the magnitude and persistence of these effects: slow, costly skill adjustment amplifies transitional employment losses and distributional gaps. Finally, we show that the sectoral direction of technological change― which skill group the technology favors―plays a central role in shaping both macroeconomic performance and inequality.
