Abstract

The purpose of this study is to analyze the disparity in on-the-job training between regular and non-regular workers and to compare the wage effects of on-the-job training. Using the Korean micro data from the Programme for the International Assessment of Adult Competencies(PIAAC) published by OECD, Propensity Score Method(PSM) is applied to overcome the endogeneity problem. The average treatment effect(ATT) on the training participation is analyzed, using non-regular workers as treatment group and regular workers as comparison group. Odds ratios of non-regular employees' training participation compared to regular employees shows 0.67 times after constructing matching sample and this means that non-regular workers are facing a disadvantageous training opportunity compared to regular workers. In order to estimate the wage effect of on-the-job training, the average treatment effect(ATT) of on-the-job training on average wages for regular workers and non-regular workers is estimated respectively. I find insignificant wage effect from on-the-job training among regular workers and significant positive effect on non-regular worker's wage from on-the-job training.

본 연구에서는 기업주도 재직자 훈련(On-the-Job Training: OJT)에서 정규직과 비정규직 근로자 간 훈련격차와 직업훈련의 임금효과를 비교분석하였다. 이를 위하여 OECD의 주관하에 조사된 국제성인역량조사(Programme for the International Assessment of Adult Competencies: PIAAC) 원자료에 내생성을 통제하기 위하여 비모수추정법인 성향점수매칭법(Propensity Score Matching: PSM)을 적용하였다. 비정규직을 처치집단으로 정규직을 대조집단으로 하여 훈련참여 및 훈련의 임금효과를 각각 추정한 결과 비정규직은 정규직에 비해 불리한 훈련기회에 직면하였고 훈련의 임금효과는 정규직에서는 유의하지 않았으나 비정규직에서는 훈련이 임금에 유의한 정의 효과를 보였다. 이러한 분석결과는 비정규직의 저숙련 함정 극복을 위한 정부개입의 근거를 제공하며 비정규직에 대한 훈련기회 확대가 미취업과 정규직을 잇는 가교로써 비정규직이 기능할 가능성을 보여준다.
