Using data from Korea Welfare Panal Study(KWPS), this study examines the relationship between public income transfers and private income transfers in Korea. This research is analyzed by the procedure of OLS regression analysis. The results are as follows. First, the paper shows that public income transfers crowded out the private income transfers. Specially public assistance crowed out the private income transfers. The amount of public income transfers has negative correlation with the amount of private income transfers. The amount of public assistance income has negative correlation with the amount of private income transfers. But social insurance transfers do not have influence on the private income transfer. Second, the private income transfers in Korea are altruistically motivated.

This study examines changes in income inequality and income mobility associated with a transition to old age. In understanding the dynamics of income distribution over the later life course, it is important to explore the changes in income dispersion and the changes in relative income positions jointly. Data come from Korean Labor and Income Panel Study(KLIPS) 2nd, 7th, 12th wave. The results are as follows. First, a transition to old age is associated with an increase in income inequality. The Gini index of inequality increased steadily over the life course. Second, a transition to old age is associated with substantial income mobility. The Spearman's rank correlation coefficient between two periods was the lowest at the time of the transition. Increasing income dispersion and significant income mobility can be conceptualized as "income insecurity", since the older population are less likely to cope with income fluctuations. Third, in explaining such changes over time, changes in work life during old age and a subsequent decrease in earnings seem to be the most influential factor.

This study conducted to examine about the income inequality and bi-polarization for forestry household. For this purpose, Gini coefficient and Atkinson index were used to analyze the income inequality for forestry household. Also, DER index were employed to show their income bi-polarization. Before using these methodologies, forestry household income was divided into three parts that was forestry income, non forestry business income and transfer income. And then, income inequality and bi-polarization were analyzed respectively. The result shows that forestry household income inequality was higher than whole household inequality. Apart from transfer income, forestry household income, forestry income and non forestry business income inequality was aggravated. At the same time, these tendency was able to observe the bi-polarization for forestry household income and other income sources.

This paper investigates the effect of household formation on the mapping from wage inequality to income inequality, which usually is smaller than the former. Added workers, income pooling among household members, and shared consumption are the factors that make income distribution less inequal than wage distribution, and the effect of income pooling appears to be the greatest. This suggests than the increase in nuclear families and the resulting increase of old families have a potential effect of worsening income inequality at the absence of sufficient private income transfers among the two households. A simple counter-factual estimate indicates that income pooling among the children's and parents' households can efficiently and sizeably reduce income inequality.

The aim of this study is to investigate the effects of income inequality caused by capital and wage incomes under globalized economic system in Korea. Empirical evidences which are obtained by cointegration methodology reveal that the effects resulted from capital and wage incomes to income inequality are alternative between short-run and long-run. And, the wage income has stronger impact on income inequality than the capital income. This might be occured as a result of that inbound foreign capital seems not to contribute to economic activity in real sector. It also has to be mentioned that the income inequality is negatively influenced by international trade in the short run and in the long run as well. To this end, it would be concluded that well-organized distribution system for wage income should be established, accordingly. And, forward and backward linkages in exporting industry have to be re-evaluated in order to improve income inequality in Korea.

The primary purpose of this study is to find policy implications by examining the trends in income inequality of the Korean aged and factors contributing to these. For analysis, this study used the 2nd, 5th, 7th and 9th wave of 'Korean Labour and Income Panel Study'. The findings are as follows. First, total income inequality of the elderly rose greatly after 1998 and is decreasing after 2001. Secondly, the Gini coefficient decomposition by income sources shows that earned income was the factor most responsible for the income inequality of the elderly. But its influences of the elderly income inequality is gradually decreasing during analysing periods. Third, assets income and public pensions have a great effects on the elderly income inequality. They increases the income inequality of the elderly households. Forth, interfamily transfer income and public assistance income reduces income inequality of the elderly.

The purpose of this study is to investigate the effect of private insurance revenues and household spending on household income inequality. To this end, we conducted a concentration index and concentration curve analysis for the income level of medical panel survey data in 2015. The main results are as follows. First, the household income concentration ratio is 0.3580, which means that income is concentrated in the high income group, and the degree of inequality is considerably large. Second, although the portion of the private insurance benefits was small on the high-income household, it helped to strengthen the benefits concentration on this group. Third, the low income group has a large self-pay medical expense. Finally, the index of the income excluding the burden of the total medical expenses in the household income was 0.3676, so that even accounting for medical expenses, the income was concentrated in the high income class. Therefore, private insurance benefits and medical expenses were all contributing factors to the inequality of household income, and this study provides the essential materials for research and policy planning which could lead to the convergence of different fields.

This study analyzes the relationship between globalization and income inequality. The empirical model is developed based on Kuznets' hypothesis of the inverse U curve. The effects of factor abundancy and globalization which is characterized by trade and FDI on income inequality are analyzed. 127 member countries of WTO are classified into 4 groups according to GNI. The period of analysis is 21 years from 1995 to 2015. Results show that 3 groups of countries excluding one group that is high income countries supports Kuznets' hypothesis which is the inverse U curve. Secondly, expansion of trade decreases income inequality of middle income countries but increases high and low income countries. Thirdly, FDI increases income inequality of middle and low income countries. Finally, the increase in capital abundancy lowers income inequality because the capital accumulation increases the productivity of labor.

Although the relationship between income and income inequality has previously been discussed, the present study applies a dynamic approach to analyze the specific relationship between forest household income and income inequality. For this analysis, a unit root test and a cointegration test were conducted to characterize the nature of income time-series data. After converting unstable time-series data into stable time-series data, a VAR model was estimated. Based on this model, an impulse-response was generated and variance-decomposition analysis was performed. These analyses showed that the effect of forest household income was relatively larger than that of the Gini coefficient, and that the impact of forest household income not only caused income to increase but also caused the Gini coefficient to decrease. In addition, the impact of the Gini coefficient had an impact on reducing forest household income and further increasing income inequality. We conclude that, with the aim of alleviating the inequality of forest household income, an income growth policy would be more effective than an income distribution policy.

The purpose of this study is to examine the effects of household income types and sources on the depressions and self-respect of the old aged. Although household income types and sources are supposed to be important to the mental health of the old aged as well as income level, there have been little policy interests to them. This study analyze the relationship between the household income types & sources and the mental health of the old aged, using the 8th data from the Korean Welfare Panel Study. Major findings are as follows. First, we find that there are considerable variations in the household income sources composition among the old aged, and that types of household income are related to the individual and family features of the old aged. Second, the results of regression analyses show that the household income types are associated with the depression and self-respect of the old aged. And, we find that some income sources affects the mental health of the old aged. The results of this study suggest that there should be policy attentions to the mental health effects of the household income sources so as to increase the adequacy of the income security system for the aged in Korea.
