This paper analyzes the changing factors of income inequality by approaches to income sources focusing on the effect of husband-wife labor income relation and employment ratio change on income inequality. The level of contribution of income source to income inequality showed that the inequality of labor income between husband and wife(especially the husband's income) takes great importance. Also, the covariance of labor income of husband and wife showed growing trend and changed toward the same direction. As a result of the decomposition of the labor income covariance, it was found that the change in husband-wife employment ratio explained the covariance change better than the change in labor income inequality.

이 연구는 한국 기혼부부가 가사노동을 어떻게 분담하고 있고, 가사노동시간의 배분에 영향을 미치는 요인이 무엇인지 검증하고 있다. 개인적인 차원에서 부부인 남성과 여성이 어떻게 가사노동을 분담하는지 밝히기 위해 성 이데올로기론, 시간제약이론, 상대적 자원이론 등 세 이론을 검토한 후 가설을 설정하였다. 가설을 검증하기 위해 2004년 생활시간조사 자료 가운데 현재 결혼해서 부부가 함께 한 가구에서 살고 있는 경우만 추출하고 부부의 자료를 하나의 레코드로 변환하여 부부의 가사노동분업에 영향을 미치는 요인을 검증하였다. 연구결과 성 이데올로기론에서 나온 성역할에 관한 태도는 남성이나 여성 모두 가사노동시간을 결정하는 데 영향을 미치지 않는 것으로 나타났다. 성역할에 관한 태도나 가치가 가사노동이라는 행위에 영향을 미치지 않는 것이다. 그러나 시간제약이론에 따라 설정된 상대적 노동시간은 남성과 여성의 가사노동시간에 큰 영향을 미친다. 이 변수가 들어간 모형의 설명력이 특히 여성의 경우 높게 나타나고 상대적 노동시간이 가사노동시간에 미친 영향은 남성과 여성 모두에 유의미하고 영향은 남성과 여성 모두 비선형적인 형태를 나타낸다. 반면에 상대적 자원이론에 따른 상대적 소득의 효과는 남성의 경우 여성의 소득이 증가하면 남성의 가사노동 참여가 꾸준히 증가하는 현상을 나타내며, 여성의 경우는 일단 여성의 소득이 있게 되면 소득의 다과에 관계없이 일정하게 가사노동을 줄이는 것으로 보인다.

To prevent the disincentive of labor supply under the current welfare system, we suggest the safety income system, a Korean version of negative income tax. Under the proposed system, for example, a household with four members whose annual income is less than 50 million wons will get financial support from the government. Under the safety income system, labor supply increases and so does the gross domestic product. The disposable income of low-income households increases, which alleviates the income gap among households. Analyzing the Household Income and Expenditure Survey data, we show that under the safety income system the disposable income differentials among households are reduced much more than under the current welfare system or under the universal basic income system.

We measured industrial labor income shares and investigated their determinants. Excluding industries where non-wage earners are not countable, we constructed 22 industry labor income shares from 1993 to 2015. Even though labor income shares in manufacturing industries declined more than in service industries, the economy-wide decline was not driven by structural changes but by within-industry effects. We found that rise in capital-labor ratio, R&D intensity, export dependence, and irregular job ratio contributed to the fall in labor income shares. When we examined manufacturing industries separately, overall results were about the same. But in that case we had additional findings that the rise in import dependence and outsourcing ratio lowered labor's shares, while minimum wage increases raised them.

본 연구는 미국의 직장근무자와 재택근무자의 비교를 통해, 남성과 여성의 소득차이를 살펴보고 이를 설명하는 요소들에 대해 분석하였다. 본 연구를 위해 설정된 가설은 다음과 같다.: (1) 성별은 직업과 시장노동의 장소를 선택하는데 있어서 유의한 요소이다. (2) 직업 및 시장노동의 장소가 결정된 후에도 성별은 시간당 소득에 영향을 미치는 변수이다. 연구자료로는 Census of Population and Housing, 1990 [United States]: Public Use Microdata Sample: 1/10,000 Sample이 이용되었으며, 16세 이상, 65세 이하의 응답자로 일주일에 적어도 한 시간 이상 일하는 근로자를 중심으로 하여 7,272명이 연구 대상으로 고려되었다. 직업 및 시장노동의 장소에 대한 선택에서 성별의 영향을 살펴보기 위해 판별분석이 행해졌으며, 분석 결과 교육수준, 연령, 인종, 남녀의 수, 주택구조와 함께 성별이 유의한 요소임이 밝혀졌다. 직업과 시장노동의 장소가 결정된 후 성별이 시간당 소득에 미치는 영향을 알아보기 위해 전체표본과 6개의 직업범주에 따라 회귀분석이 실시되었다. 전체표본을 대상으로 한 회귀분석의 결과, 시간당 소득을 예측하는데 있어서 성별은 유의하지 않은 것으로 나타났으나, 6개의 직업범주에 따라 시간당 소득을 추정한 결과, 성별은 모든 직업범주에서 유의한 것으로 나타났다. 그러나 재택근무자가 되는 것은 시간당 소득을 규정하는데 있어서 유의한 변수가 아닌 것으로 나타났다. 이것은 특정 직업 내에서 시장노동의 장소보다는 성별이 재택근무자에 있어서 소득의 차이를 설명하는데 중요한 요소임을 암시하고 있다. 본 연구에서 사용된 자료는 직업 및 시장노동의 장소에 대한 결정이나 소득에 영향을 미칠 수 있는 변수들에 대한 충분한 정보를 갖고 있지 않고, 또한 재택근무자의 표본수가 너무 적었기 때문에 일부 변수들은 직업의 선택이나 소득을 예측하기 위한 요소들로 포함될 수 없었다. 따라서 후속연구에서는 이를 보완해야 할 것이며, 최근 들어 우리 나라에서도 재택근무에 대한 관심이 대두되고 있으나 아직 개념정의나 그 중요성과 가치, 그리고 실태 파악과 같은 연구가 활발히 이루어지지 못하고 있으므로 이에 대한 심층적인 연구가 행해져야 할 것이다.

This paper investigates how individual labor income is determined by initial conditions - such as educational attainment, age, and sex - and all the other conditions. Using KLIPS (Korea Labor & Income Panel Study) database, the paper finds, first, that over the period of 1998-2008, cross-sectional income distribution has deteriorated for the whole sample but not within each age group. Second, income mobility defined by the relative importance of initial conditions in individual income disparities has moderately increased in most age groups.

Labor share of income in Korea has fallen from 90% in 1996 to 79% in 2010. This paper explores the factors driving the movements in the labor share of income based on a panel dataset containing 19 years of data on 18 Korean manufacturing industries. The effects of technical progress, globalization and the bargaining power of labor and capital on the labor share of income are tested for the period of 1991-2009. The main empirical results are as follows. (1) Capital-aug menting technical prog ress measured by capital-labor ratio and R&D intensity has a negative effect on the labor share. (2) Market openness measured by the value of export and import as a ratio to value-added production is found to have a positive impact. (3) Globalization of production measured by inward-FDI and outward-FDI as a ratio to total domestic fixed capital is found to have a negative impact on the labor share. (4) Union density is found to have had a statistically significant effect in 1991-1998. This finding is consistent with the efficient bargain model in which firms and workers bargain over both wages and employment. But union density is insignificant in 2000-2009. This implies that since the financial crisis in 1997, the bargaining institution in Korea has been approaching the right-to-manage model in which firms and unions bargain over wages and then firms set employment unilaterally. (5) Variables for domestic financialization measured by dividend-income ratio and financial-fixed assets ratio have an insignificant effect on labor share.

This study examines whether the widening gap between income groups is worsening in the distribution of time use, similar to the worsening of income distribution after the IMF. To do this, we conducted multilevel analysis (HLM) on six countries including France, the Netherlands, Spain, the United Kingdom, the United States and Korea. The results of the analysis are as follows. First, in all countries, low income groups have a longer paid working time and shorter leisure time. Second, the low income groups in Korea have the longest paid work time and the shortest leisure time, the lowest level of work-leisure balance, and this aspect has not recovered since the IMF. Third, as the result of multilevel analysis, the lower the household income, the more time paid labor increased and the work-leisure balance decreased. Fourth, while average annual working hours increase paid working time, the expansion of family policy expenditure, redistribution policy and income maintenance policy has reduced it. Fifth, the annual average working hours decreased the work-leisure balance, but the family policy expenditure, the redistribution policy and the income guarantee policy increased the work-leisure balance. The significance of this study is that after the IMF, not only the income distribution but also the inequality among the income class in time use has deepened. Based on the results of the research this study suggests the reinforcement of labor time regulation, the activation of parental leave system, the realization of the income replacement rate, the expansion of the policy related to income redistribution, and the complementary development of the income guarantee and the time guarantee policy as the policy intervention strategy that restructures time.

This study estimates what fraction of the rise in household income inequality in Korean between 1996 and 2000 is accounted for by the change in each of the household income components, such as wages, employment, hours of work of household heads and spouses, household structure, and other incomes. The increased disparities of household heads' wages and labor supply explain, respectively, 70% and 34% of the rise in the difference in incomes between the top 10% and bottom 10% households. Changing labor supply of spouses, in contrast, was a strong countervailing force that diminished the measure of household income inequality by 21%.

The objective of this study is to examine the trend of real earnings for TANF leavers. Using administrative data in Wisconsin, this study tracks the 1998 TANF leavers over 7 years. Based on the cyclicality of real wage hypothesis, this study finds: First, although the average real quarterly earnings of TANF leavers have remained stable since their exits, there are substantial labor mobility among TANF leavers. Second, the panel data analysis shows that the real earnings of TANF leavers are significantly associated with local labor market conditions, which supports the hypothesis on the cyclicality of real wages. This study has policy implications that labor market conditions matter for the economic well-being of TANF leavers and the labor demand policies are needed for the economic security of TANF leavers after the exit.
