정보통신기술확산이 임금불평등의 한 원인인가? = Information and Communication Technology and Wage Inequality

다국어 초록 (Multilingual Abstract)

This paper explores, using the traditional Mincer-type earnings equation augmented by a proxy for ICT progress, whether the differing pace of Information and Communication Technologies (ICT) has an effect on both within- and between-group wage inequalities. We found that the pace of ICT progress caused the widening of both within- and between-group wage inequalities. An important policy implication of this finding is that as the forces of labor demand tend to increase wage inequalities among workers at least until the pace of ICT progress stabilizes, policy measures to provide more opportunities for training and job experience for workers and the extension of the social safety net for vulnerable workers are necessary.

국문 초록 (Abstract)

본고는 산업 및 사업체 수준의 자료를 이용한 Mincer류의 임금방정식 추정을 통해 산업간 혹은 사업체간 상이한 수준의 ICT 확산이 동일직능집단 내 임금불평등 확대 및 고직능-저직능노동간 임금불평등 확대에 기여하는지를 탐구하였다. 그 결과 ICT 확산속도의 차이가 부문간 임금격차 확대를 통해 동일직능 집단내 임금불평등 확대에 기여함을 알 수 있었다. 또한 ICT확산속도의 차이가 집단간 임금불평등 확대에도 기여함을 명시적으로 확인할 수 있었다. 이상을 종합해 볼 때 기술변화속도가 급격한 시기에는 노동수요구조가 고용안정성 및 소득분배 상황을 양극화시키는 경향을 띠므로 근로자의 직업교육 및 직업경험 기회를 확대하고, 저직능근로자에 대한 사회안전망의 충실도를 제고하는 등의 정책적 배려를 강화해야 할 필요가 있다고 하겠다.
