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."

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.

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.

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%.

오늘날 여성은 고학력화와 더불어 여성 전문직 비율 증가, 직장에서의 승진기회 확대, 소득증가, 미혼여성의 급증, 결혼 연령의 증가 등으로 과거와는 달리 사회참여의 기회가 다양하게 증가하고 있다. 이에 따라 여성 중에 기혼 여성은 가정용 전자제품의 발달로 육아노동 및 가사노동의 감소 및 낮은 출산율을 보이고 있고, 미혼여성의 비율은 증가하는 추세에 있다. (중략)

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.

2002년 농가소득은 도시근로자가구소득에 비하여 73.0%로 불과하고 매년 그 격차는 확대되고 있다. 또한 농외소득의 비중이 53.9%로 일본 87.0%, 대만 79.5%, 미국 94.7% 등에 비해 그 비중이 매우 낮아 농외소득원 개발이 필요한 실정이다. 더구나 인구 3천명 이하 면수가 1990년 152개 지역에서 2000년에는 447개로 증가하는 등 농촌지역에 인적이 끊어지고 있는 곳이 증가하여 어떻게 지역을 유지해 나갈 것인가가 중요한 과제로 대두되고 있다.(중략)

Analysis based on the Korea Labor and Income Panel Survey data reveals that earnings have become less volatile since the exchange rate crisis, while they have become more unequal. The reduction in measured earnings volatility is not explained by changes in the composition of various economic/demographic groups but accounted for by within-group reduction in the measured earnings volatility, which in turn is attributed to the reduced earnings mobility during the sample period. It is also found that measured earnings volatility is countercyclical and earnings changes are symmetric even during recessions.

This study investigated the tax compliance applying framing effect, with the influence of detection rates, client advocacy, risk seeking tendency on the amount of income declared. Questionaires were filled in by CFA in Busan. Questionaires involve three cases (newly founded company, loss-expected company, gain-expected company). Respondents declared least in newly founded company, next loss-expected company, to gain-expected company. Respondents declared more as detection rates rose. As client advocacy increases, newly founded company and loss-expected company declare less, while gain-expected company declare more. As risk seeking tendency increases, newly founded company and loss-expected company declare less, but gain-expected company. Finally the interaction effect between client advocacy and risk seeking tendency is supported.
