The income of wage earners and the transition of the inequality of their income from 1993 through 1998 have been analyzed. Korea's economy went through an epochal change since the beginning of the IMF economy and the inequality of income, which is part of the change incurred by this situation, has been studied in this thesis. The 'human capital theory' has been chosen as the basis of study. Also, gender, educational background and age, which are the key variables of the 'human capital theory', have been set as independent variables to compare each variable's influence in the distribution of income. From 1993 to 1998, the effect of gender has shown a fluctuating pattern whereas the effect of education declined slowly and the effect of age rapidly. The accumulative effect of the three variables show a fluctuating pattern, but at a declining mode. Though discrimination against gender, educational background and age, in terms of income, is at a declining mode, it is apparent that it still exists. Especially, discrimination against gender is continuing at a fluctuating pattern.

The GyeongNam Province is one of the regions that have first introduced chrysanthemum farming in Korea since the 1960s. The chrysanthemum growers of The GyeongNam Province had strong competitiveness in production and marketing, so the their income ratios were relatively higher than any other growers of other provinces. The income ratio of The GyeongNam Province, however, has continuously decreased and stays currently below ratios of other provinces. The purpose of this paper is to find out which factors have contributed to the decrease in income ratio of GyeongNam Province. The analysis indicates that the increase in production cost was the main causes of rapid drop in income ratio. It is also worth mentioning that the income ratio falls dramatically when oil price (duty-free oil) rises above 700 won per liter.

Since the 1980s, the western welfare states have experienced a wide spectrum of socio-economic changes; changes in population composition, the economic globalization, the post-industrialization, an increasing flexibility in the labor market. etc. This study examines the trend of poverty in welfare states, and analyzes how those socio-economic changes are related to it. For these purposes, this study first calculates the poverty indices for several years in 10 welfare states using the Luxembourg Income Study database, and then decomposes the index by subpopulation and income sources. Major findings of this study can be summarized as follows. First of all, the welfare state in general has experienced an increasing trend in the degree of poverty since the 1980s. In particular, poverty has greatly intensified in the United Kingdom and the Netherlands. Many other welfare states including Canada, Germany, Sweden, and Norway have also experienced substantial increases in poverty. The increasing trend of poverty is not wholly due to changes in population composition such as increases in the aging population and one-parent(mother) families. Contrary to the traditional belief, these population groups are not as much poor as the working-age population. In particular, the degree of poverty in the elderly is less severe than in the working-age group. Furthermore, since the 1980s the market income poverty in the aging population has shown a decreasing trend in many welfare states. The degree and trend of poverty in one-parent families vary greatly across countries, owing to the labor market and income transfer policies. The most important reason for the increasing poverty trend in the welfare state is that the degree of poverty has been deepening in the working-age population. Especially, the market income poverty of the working-age population has considerably increased in every country except the Netherlands. Structural changes in the economy and the labor market may drive the increasing trend of poverty. Further studies and deliberate anti-poverty policies are needed to tackle the factors relating to the increase in the market income poverty.

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.

Self-employment rate is high in Korean labor market, while the income gap within self-employed is also high. Although, there are very few studies that addressed on the income inequality of self-employed. Thus, this study has measured the earnings inequality of self-employed by generalized entropy indices and decomposed inequality factor and trend. The empirical study is based on Korea Welfare Panel Study wave 1~4. The main result from this analysis is summarized in three points. Firstly, earnings inequality of self-employed is severely high and the earnings polarization within self-employed has become more serious in Korea. Secondly, this study provides the evidence that the main factor of earnings inequality of self-employed is the status of self-employment, education level, age group, workplace scale and industry. Thirdly, the contribution of relative changes in the incomes of the status of self-employment is the largest to the inequality trend. In terms of education level, age group and industry, the increase of inequality within group(pure effect) mainly attributes to the rise of earnings inequality of self-employed and the change effect of group composition contributes to deterioration of inequality.

Korean households' demand for food consumed away from home is on the steady increase. The ratio of eating-out expenditure of the household income, however, tends to decrease recently irrespective of income groups. This paper, therefore, aims to analyse the food-away-from-home expenditures of salary and wage earners' households by income decile group. The eating-out expenditure is modelled as a function of household income and then estimated using econometric methods such as regression, rolling regression, impulse response, and variance decomposition of forecast error. The regression results indicate that the higher the income decile group is, the lower the income elasticity of eating-out expenditure is, and the high income groups enjoy seasonal eating-out, the low groups do not. The coefficients of dynamic rolling regression are much smaller than those of static one, meaning that households tend to decrease the eating-out expenditure of their income. The impulse response analysis suggests that the eating-out expenditure increase of higher income groups lasts long relative to that of lower income groups. The variance decomposition, also, shows that household income plays much more important role in determining eating-out expenditure at the higher income groups than at the lower income groups.

This paper analysis the long-run demand for monetary indicator M2 and Liquidity indicator L in Korea in the period from 1980:1 to 2006:3 by cointegration and error correction models. The empirical evidence that M2, L in Korea is meaningfully cointegrated with income, interest rate, exchange rate, inflation uncertainty, real effective exchange rate, exchange rate uncertainty and LIBOR, thus showing the existence of long-run demand function under open-economy framework.

The purpose of this analysis is to examine the effects of health expenditure on income inequality on household income after the financial crisis by using the household income survey form 1996 to 2016. The main results are as follows. First, after the financial crisis, the gross income inequality of households has been changing steadily, though there has been a slight change in each year. Second, high-income earners spend more on health care expenditure by income level. Therefore, unequal levels are maintained. Third, the Gini coefficient of income excluding health care expenditure was calculated. The results of the analysis are larger than the Gini coefficient of total income. Income inequality is intensified by the expenditure of health care expenditure of households. The inequality of household income due to health care expenditure has been increasing steadily since the financial crisis. Efforts such as strengthening the protection of health insurance have been continuously carried out for the purpose of reducing the burden of the national medical expenses. However, it does not contribute to resolving income inequality. In the future, it will be necessary to provide a more selective medical support system to reduce the medical expenditure of the low income class.

This paper documents the increase in earnings variability (or earnings risk) during the 1990s in Korea, and investigates whether it can be accounted for by capital market opening. The variances of transitory and permanent innovations in earnings are estimated from repeated cross-section data using a simple econometric framework. The increasing time-series pattern of earnings risk among men follows the increased foreign capital presence reasonably well, but the supporting cross-sectional evidence for a causal relationship between the two is weak. However, foreign direct investment (FDI) is found to have had some non-neutral effects on workers of varying skills in such a way that transitory earnings risk of less-skilled workers relatively increased with FDI. To the extent that transitory innovations are not fully insured, this widening effect of FDI on earnings risk gap may have contributed to widening welfare gap between skilled and unskilled workers in Korea, at least in terms of "risks."
