경제위기 이후 가구단위 소득 구성요소와 직업의 소득불평등 효과: 도시 임금소득자 가구를 중심으로

This paper examines the effects of income-composing factors and occupations on the family income inequality after the economic crisis in Korea, By focusing on the urban wage-earners, the paper analyzes the causal relationship between income differentials and occupational composition at the family level. The major findings based on the analysis of variance and regression are as follows. First, family income differentials are higher in the post-crisis period than in the pre-crisis period. The differentials came mainly from the wage gap by the bread-winners. Second, the occupation of the bread-winners at the family level has a significant effect on the income differentials. Whereas family incomes of the managerial or professional occupations get higher, those of the unskilled workers lower. Third, the degree of income inequality became higher after adding the income of other family members. While the proportion of dual-earner-family increases, the occupation of the family members tends to be similar each other. Finally, the relatively low family income of the unskilled workers is one of the main causes of the income differentials in Korea. These findings suggest several policies for reducing inequality at the family level. One of them is the policy to increase the income of all family members, especially that of wife. If they have decent jobs, their chance of being out of poverty trap would be higher. Public policies for human resource management and job creations could lead them to get decent jobs.
