본 논문은 한국의 임금소득불평등도가, 다른 구미제국과는 달리, 1970년대 중반 이후 1993년까지 지속적으로 감소하여온 원인을 알고자 작성하였다. 특히 임금방정식의 추정을 통해 임금불평등도를 원인별로 분해하는 새로운 방법론을 처음 적용시킨 논문으로, 일정시점과 일정기간에 있어서의 원인별 기여도의 수량적 측정을 통해 불평등도를 분해하였다. 이러한 분해를 통하여 1980년대 중반 이후 한국의 임금불평등도가 감소된 주된 원인은 노동조합운동에 기인한 제도적 측면이 아니라 대졸자의 공급확대에 기인한 교육의 투자수익률 감소에 따른 시장적 측면이었다는 점을 보였다. 또한 1993년 이후 임금소득불평등도는 점차 확대되고 있으며, 최근 실업의 급증과 함께 불평등도의 확대가 더욱 심화되고 있는 것으로 파악되고 있다.

Researches on inequality in Korean society has been sporadically conducted in various areas. In this study, research trend related to inequality was analyzed through basic statistical analysis, co-occurrence analysis, and main path analysis using articles related to inequality from Korea citation index. In basic statistical analysis, key authors, journals, and articles are identified. In co-occurrence analysis, income inequality, educational inequality, welfare inequality, and policy on inequality were identified as main topics. Main path analysis showed two research trends after 2004. One was research trend on economic inequality, and the other was on health inequality and social structural inequality.

본 연구에서는 수학성취도에서의 불평등도를 모색하였다. 구체적으로 경제적인 불평등도로서 널리 사용하는 지니계수를 활용하여 학업성취에서의 불평등도를 계산하였고, 불평등성에 대한 언어적 해석의 기준을 마련하였다. 자료 분석 결과는 농촌지역보다는 중소도시, 중소도시보다는 대도시, 대도시의 일반고 보다는 과학 고등학교에서의 불평등도가 약하게 나타났다.

This paper compares income and consumption inequalities in Korea and applies the permanent income hypothesis to interpret the linkage between the two inequalities. Income inequality has been increasing since 1990 while consumption inequality had been decreasing until the early 2000s when the two inequalities started to co-move. Permanent income hypothesis explains reasonably well the consumption pattern in the recent period, which reflects the increased access to asset markets by the Korean households. Consequently, the co-movement of income and consumption inequalities in the recent period implies that inequality in permanent income components are fluctuating.

This research attempts to explain the influence of educational level inequalities on self-rated health and depression of the elderly. Also, we are focusing whether there is a mediating effect of social support between educational level inequalities and self-rated health depression of the elderly. The data was collected from July, 30 to August, 15, 2009. 631 persons who live in Gangnam-Gu area over 60 years of age were recruited. Frequency, percentage, mean, standard deviation and multiple regression were employed using SPSS 12.0. The result of this study shows that educational level inequalities have a influence on the self-rated health and depression. It is also verified that social participation variable has a partial mediating effect between educational level inequalities and mental health(self-rated health and depression). This study carried out a positive linear relationship between educational level and health: the higher education, the better the health. And also, the results present the importance of developing adequate intervention programs for the elderly having low educational level to improve social participation and to enhance mental health(self-rated health and depression).

This paper compares income and consumption for their relative effectiveness in measuring inequality. Although income inequality has received more attention in the literature, the permanent income hypothesis links consumption to welfare more directly than income. To the extent economic agents smooth their consumptions, consumption inequality is a better indicator for an economy's welfare inequality, and it is especially so when income volatility is high. The empirical analysis in this paper indicates that the income and consumption patterns among the Korean wage/salary worker households are quite consistent with the permanent income hypothesis. Further, it is found that consumption inequality tends to be lower than income inequality, and more importantly, that the two inequalities do not always vary in the same direction. These results call for stronger emphasis on consumption inequality in inequality literature.

The purpose of this study is to examine the trends of income inequality by gender since 1997 economic crisis and to investigate what is the most influential factor on these changes for males and females. Data used for this study are nine waves of Korean Labor and Income Panel Study(KLIPS). Income inequality is measured by the Gini coefficient and the mean logarithmic deviation(MLD) and the MLDs are decomposed into three components to quantify within- and between-group inequalities. The results show that the extent of income inequality is greater for women during the whole period and is fluctuated more widely. Women's income inequality is mainly affected by the family-related variables, such as age and marital status, while men's inequality is primarily determined by the labor market factors, such as employment status, industrial types and occupation status. These results imply that gender-sensetive welfare policies need to be implemented and that it is necessary to assist the poor women and men through the benefits from the income assistance programs and labor market programs.

본(本) 연구(硏究)에서는 1984년 한 해의 "도시가계연보(都市家計年報)"(전산(電算)테이프자료(資料))를 이용해 도시가구(都市家口) 계층간(階層間) 및 계층내(階層內)의 소득(所得) 및 소비(消費) 후생불평등도(厚生不平等度)를 추정하였으며 그 요인(要因)을 근로소득(勤勞所得)의 측면(側面)에서나 찾아보았다. 본(本) 연구(硏究)의 주요실증분석(主要實證分析) 결과(結果)는 다음과 같다. (1)도시가구(都市家口)의 불평등(不平等)을 크게 좌우(左右)하는 것은 재산소득(財産所得) 유무(有無)이며 (2)근로소득(勤勞所得)의 불평등(不平等)은 주로 학력간(學歷間) 임금격차(賃金格差)에서 비롯되고 있으며 (3)재산소득(財産所得)의 불평등(不平等)은 자본이득(資本利得)(capital gain)을 좌우(左右)하는 일반물가수준(一般物價水準)의 불안정(不安定)에서 비롯되고 있다. 따라서 불평등(不平等)의 개선(改善)을 위해서는 무엇보다도 먼저 물가수준(物價水準)의 안정(安定)이 최우선 조건이며 이와 더불어 학력간(學歷間) 임금격차(賃金格差)를 완화(緩和)시키는 노력도 병행되어야 할 것으로 보인다.

The purpose of this study is: (1) to compare the awareness of inequality concept between Korea and other countries using the survey, (2) to identify whether several inequality measures, which have diverse concepts, are different in empirical aspect, and (3) to suggest the direction for the income distribution policy in Korea. The results of the survey has shown a surprising fact in that the majority of respondents do not agree with the basic assumptions outlined by Gini coefficient, which is the relative inequality measures that had been generally accepted in the past. These results are very similar to those of other countries. However, the major difference with other countries is that the Koreans feel that absolute income inequality-the income gap between the poor and rich, has increased more than relative income inequality, when all incomes of social members are doubled. From the result it is difficult to say that the bi-polarization index is different from Gini coefficient in statistical aspect although it has different theoretical background. The national development strategy should seek to promote "the pro-poor growth" since the change of inequality affect differently on the change of growth and inequality depending on whether the inequality change is relative or absolute.

This study examines recent trends in income inequality among the elderly in Korea. Aggregate income inequality trends are explained by examining evidence from inequality index decomposition by population subgroup and by income source. Data come from Korean Labor and Income Panel Study(KLIPS). The results are as follows. First, elderly income inequality increased from 1999 to 2002, and then decreased until 2008. Second, household composition changes appear to have disequalizing influence. The proportion of elderly people who are economically dependent on non-elderly family member or living with adult children has declined. Equalizing influence of private transfers also decreased between 2002 and 2008. These results indicate that the redistributive role of family has weakened over time. Third, the improvement of education level and changing occupational structure among the elderly household head contributed to increase in elderly income inequality. Fourth, earning's factor share has declined steadily, and the diminishing role of earnings provides equalizing influence on elderly income inequality from 2002 to 2008. Fifth, the impact of recent expansion of social insurance has changed over time. Inequality contribution of social insurance income increased from 1999 to 2002, and then decreased from 2002 to 2008.
