본 연구는 한국노동패널 1998-2001 자료를 이용하여 성장기에 경험한 가족구조와 저소득, 빈곤 등의 가족배경이 청소년의 교육성취 미치는 영향을 분석하였다. 가족구조와 가족소득, 빈곤의 영향을 각각 분석한 결과 각 변수는 청소년의 학력연수와 대학입학확률, 진학고교유형과 통계적으로 유의미한 관계를 보였다. 19세의 학력연수와 대학진학확률의 경우 이혼 별거가족의 청소년과 한부모가족을 장기적으로 경험한 청소년, 빈곤가족의 청소년은 특히 낮은 수준의 성취도를 보였다. 가족구조가 19세의 교육성취에 미치는 영향은 소득수준이나 빈곤을 통제한 후에도 지속되는 것으로 나타났다. 소득과 빈곤의 영향력 또한 가족구조가 모형에 포함된 후에도 큰 차이가 없었다. 반면에 16세의 진학고교유형에 대해서는 가족구조와 가족소득을 같이 모형에 포함하는 경우 가족구조의 영향은 일관되지 않고 빈곤의 영향 또한 사라진다. 가족구조와 빈곤의 상대적 영향력을 두 변수가 모두 통계적으로 유의한 영향을 미친 대학진학모형에서 비교한 결과 가족구조의 영향력이 큰 것으로 나타났다. 이러한 본 연구의 발견은 한부모가족과 빈곤가족에 대한 사회적 지원 대책이 청소년 교육성취 수준을 향상하는 데에 크게 기여할 수 있음을 시사한다.

본 논문은 전력수요와 내구재의 구매를 결정하는 과정을 모형화하고 소득효과를 추정해 보기 위한 것이다. 효용극대화 원리에 기초하여 개인의 의사결정과 관련된 동시성을 규명하고, 이를 논리적으로 설명할 수 있는 모형을 설정함으로써 전력소비와 관련된 보다 정밀한 정보를 얻을 수 있음을 보이고 있다. 소득효과를 추정하는데 있어서 소득이 소비에 주는 영향을 단기와 장기로 나누어 추정한다. 단기의 경우에는 내구재 보유수준이 정해져 있기 때문에 이용율만 상승한다. 그러나 어느 정도 시간이 지나면 효용을 극대화하기 위하여 내구재 보유수준을 높이고 이에 따라 소비수준이 더 늘어나게 된다는 가설을 미시자료(micro data)를 통해 실증적으로 분석한다. 소득효과는 계절별로, 그리고 소득계층별로 보이는 다양한 분포를 추정한다.

The purpose of this study was to offer a comprehensive analysis of the changing trends of the Korean income packaging, poverty rate, and level of income inequality from 1996 to 2002. In order to do that, this study used the micro-data of "Income and Expenditure Survey of Urban Households" by the National Statistical Office(NSO). Major results were as follows: (1) A ratio of public transfer in family income packaging increased at the DJ administration. (2) Poverty rate and Gini coefficient, which were 7.8% and 0.29 in 1996, rose to $8.8{\sim}10.4%$ and $0.30{\sim}0.34$ respectively during the year of 1998-2002. (3) However, poverty reduction effect and income inequality reduction effect of public income transfer increased preferably at the DJ administration. Those effects increased more since the enactment of National Basic Livelihood Security in 2000. Therefore, government should provide more national welfare programs to reduce the poverty rate and to improve better structure of income distribution.

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.

This study estimate the adequate replacement rate of retirement income by income brackets and suggests roles of pension and non-pension income sources to achieve it for each income bracket. Priori research focused on elderly poverty; however, there has been little discussion about an adequate income level for retirement. We calculate an adequate income replacement rate separately for the poor, middle, and high income group as well as the average level of replacement rate for all groups. We also investigate the gap between the adequate income replacement rates and realized rates, and propose roles for each income source to curtail the gap. It is essential to recognize that the adequate income for retirement is unable to be met only by an annuity. To emove the gap, it is vital to utilize non-pension income although annuity is a primary source for retirement. Especially, the public and private pension plays a role to overcome poverty and live affluent in retirement, respectively.

The regional differences between urban and rural areas make many diverse differences. There are various differences between urban and rural areas such as economic gap and cultural gap. There is also a difference between urban and rural areas in accessing and utilizing information. The purpose of this study is to clarify the relationship between the information gap and the income gap among farmers and fishermen groups, where information gap is considered to be more serious than other groups. In other words, we tried to examine whether the information gap between farmers and peasants affects the income gap. The purpose of this study is to analyze the relationship between informatization level and income of farmers based on the information gap index and survey results conducted every year by the government. The results show that there is a statistically significant positive relationship between the informatization level of farmers and household income. In addition, the trend of the regression coefficient is positive, suggesting that the government needs various informatization policies to increase the informatization level of farmers.

This study examined the effects of the economic activity status on the mental health of middle and older adults. In terms of mental health, a theoretical model was used to evaluate the mediating role of the income level and the satisfaction in family relationship. Using data from Korean Longitudinal Study of Ageing, job seekers and those who had never worked before were excluded and employees and retirees (over 45 years old) who have both a spouse and children were selected for the analysis. The variables were the economic activity status, the income level, the satisfaction in family relationship, and the mental health. The results show that the number of employed middle and older adults were higher than that of retirees, and the satisfaction in family relationship were generally high. In terms of mental health, the level of happiness was high, while the level of depression was low. Also, the pathway analysis of the effect of the economic activity status on the mental health shows that the economic activity status directly affects the mental health and gives indirect effects through the medium of the income level and the satisfaction in family relationship.

This study investigates the difference in income trajectories of the working poor and the non-working poor and explains the effects of socio-demographic (marriage, education) and regional (living in large cities) factors on intergroup differences. We use Seoul Survey data collected between 2009-2018 and the latent growth modeling approach. It was found that the trajectory difference between groups was statistically significant. Since 2016, the income gap widened as the income of the working poor stagnated. The three variables included in this model better explained the income trajectory of the working poor compared to the working non-poor. In particular, the change in income growth rate was positively related to whether they live in large cities. This suggests the possibility that living in a large city would act as an economic premium for the working poor. It is necessary to conduct follow-up studies on urban premiums for the working poor.

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.
