This paper attempts to re-evaluate the size of housing wealth effect in Korea. Our focus is on the size of 'genuine' housing wealth effect, i.e., the response of consumption spending by home-owners to the changes in housing wealth. Two issues show up while we estimate the 'genuine' wealth effects using aggregate time series data: the issues around home ownership and proper measure of consumption. We first argue that it is more appropriate to use non-housing consumption, because housing consumption is in large part not of the choice of home owners but the imputed rents they do not actually choose to pay. We then proceed to address the issue of home ownership, by examining how much to revise the estimates of housing wealth effect obtained from aggregate non-housing consumption data. We construct two structural models and estimate the share of home-owners' consumption in those models' context. It is found that, if properly revised in light of the estimated consumption shares of home-owners, the magnitude of resulting housing wealth effects are larger than what simple time series regressions imply.

This study analyzes the consumption patterns of the poor households. The first objective of this analysis is to show that the group living in poverty get not one consumption pattern but several types of consumption patterns. The second objective is to understand what factors effect the consumption patterns. This study use the data of Korea Welfare Panel Study in 2008 & 2009. In oder to achieve first goal, We conduct factor analysis and cluster analysis. And to achieve second goal, We conduct multinomial logistic Analysis. Major findings are as follows. First we find six patterns of consuming types of the poor households. They are education oriented consuming type, diet oriented type, social network oriented type, transportation-communication oriented type, health & medical oriented type, and housing expenditure oriented type. Second we find these consumption patterns are effected by not economic factors but socio-populational factors, especially by life cycle of members of household.

The purpose of this study was to investigate the relationship between householder's education level and the education expenditure for children. The Family Income and Expenditure Survey data of the 2005 National Statistical Survey were used to examine the hypothesis. For data analysis, ANOVA and regression method were applied. The results are as follows: House-holds in Seoul spent 533,000 won for child education per month on the average, and 64% of the expenditure was for private education. Households whose householder's education level was high spent more expenditures on public and private education for children than the households whose householder's education level was low. When the household income level was controlled, householder's education level affected only private education expenditure.

외환위기 이후 재정적자가 급격히 확대되면서 재정적자에 대한 일반인들의 관심이 높아지고 있다. 그러나 재정적자가 거시경제에 구체적으로 어떤 영향을 미치는가에 대한 실증분석은 많지 않은 편이다. 본고는 재정적자가 민간저축률과 물가상승률에 미치는 영향을 살펴보고 있다. 본 논문의 결과를 요약하면 다음과 같다. 첫째, 저축률과 재정적자 사이에는 리카도 동등가설이 예측하는 것과 같은 관계가 표면적으로 발견된다. 즉, 재정지출이 변하지 않을 때 재정적자의 증가는 민간저축률을 증가시켜 국민경제 전체의 저축률은 크게 변하지 않는다. 둘째, 재정수지가 변하지 않더라도 재정지출의 증가는 민간저축을 감소시킨다. 그리고 재정수지가 변하든 변하지 않든 정부소비나 이전지출의 증가는 국민저축률을 감소시킨다. 셋째, 재정적자는 물가에 별 영향을 주지 않는다. 이 가운데 첫째와 셋째의 결과는 별로 새삼스러운 것이 되지 못한다. 그러나 둘째의 결과는 지금까지 논의되지 않았던 사실을 알려주고 있다. 특히 1980년대 말 이후 GDP 대비 재정규모가 추세적으로 증가하고 있으며, 최근의 외환위기 이후에는 금융구조조정 지원 등에 따라 재정규모가 급격히 증가하고 있고, 장기적으로는 국민연금급여 등 사회보장지출의 증가가 예상됨을 고려할 때, 재정규모 증가를 억제하는 일에 보다 적극적인 노력을 기울일 필요가 있음을 알게 된다. 한편 본고에서의 한국은행의 준(準)재정활동을 고려하지 않았으나, 이를 고려할 때에도 재정수지가 물가상승률에 별다른 영향을 미치지 않는지에 대한 추가적 연구가 필요하다고 판단된다.

민주주의의 꽃, 제 20 대 국회의원 선거가 막을 내렸다. 지난 선거에서는 방송사뿐만 아니라 정당들도 엄청난 비용 지출과 노력이 소요되었다. 한 예로, 지난 4. 13 총선거 (제 20 대 국회의원)에서 방송 3 사 출구조사 비용으로 약 66 억원 이상이 지출됐다. 그리고 정당에서는 여론조사 비용으로 약 70 억원 이상을 지출했다. 이러한 큰 비용 지출과, 담당자들의 노력을 줄이기 위해 본 논문에서는 텍스트 마이닝과 감정분석을 적용한 후보 당선자 예측 어플리케이션을 제안한다. 첫째, 소셜 그래프 모델을 소개하여 지역 구조를 발견한다. 둘째, 텍스트 마이닝 기법을 이용하여, 후보자 관련 데이터를 가공한다. 셋째, 텍스트 감정 분석을 통해 후보자의 정보를 수치화 한다. 본 논문의 성능과 효율성을 평가하기 위해, 제 20 대 국회의원 선거에 사례연구를 진행하였다. 제안한 방법이 정확도와 수학적 통계 검증을 통해 가치 있는 효율성을 보였다. 선거방송을 위한 후보자 예측 도구의 도입으로 향후 선거(방송)에서의 큰 비용과 노력을 줄이는데 도움을 줄 것이라 기대한다.

The purpose of this research was to examine the level and trends in household clothing expenditure in Korea. Raw data sets produced by the National Statistical Office from the Family Income and Expenditure Survey from 1991 to 2004 were used to support time-series and cross-sectional analyses. The clothing expenditures decreased severely and quickly during the economic crisis of late 1997 through 1998, then increased slowly after the economic crisis until 2003, only to slightly decrease again in 2004. The ratio of clothing expenditure to total household expenditure decreased from 8.03% in 1991 to 5.11% in 2004. This decrease in relative clothing expenditure was greater in the lower income group than in the middle and high income groups. Clothing expenditure patterns were unique and differed from other household expenditures. Although the economic crisis in the late 1990s affected Korean consumers' clothing expenditure, clothing expenditure patterns showed a more fundamental and structural change from 1991 to 2004, with the overall decrease in such expenditure resulting from the concurrent increase in educational and information-communication related expenditures. Clothing expenditure was shown to be luxurious through cross-sectional analysis, but necessary through time-series analysis.

In this study, using the raw data of the 7th Food Consumption Behavior Survey(2019), compare and analyze what factors affect the food delivery service and take-out food expenditure of single-person and multi-person households. It was found that women(especially women in single-person households), have a high tendency to pursue safety preference versus price. In the future, Korea's population structure is expected to steadily increase single-person household and elderly households, and women's participation in economic activities is expected to continue to increase. In addition, the food delivery market has more than doubled compared to the previous year in 12 cities and provinces out of 17 cities and provinces nationwide with Covid-19, especially in the non-capital area, making it has become a universal service nationwide. Therefore, the growing home meal replacement market needs marketing strategies to secure and emphasize food safety.

The causes of indebted overspending were investigated by examining household expenditure patterns using the data from the 2002 Family Expenditure Survey. The five major expenditure categories were identified by factor analysis, and the six types of indebted overspending were clustered. About 28% of the indebted overspending was done out of necessity, and food, utilities, housing, and health care accounted for about 42% of the household expenditure. Luxury spending accounted for about 25% of the overspending by indebted households who spent about 24% of the household expenditure on clothing, entertainment, and private education. Cars (22%) and education (20%) were found to be other major causes of indebted overspending. Paying off debt and durable purchases were identified as the major causes of indebted overspending, but had a low frequency. Finally, the financial status of the four major types of indebted overspending households was evaluated.

This study is to investigate the important factor for household private education expenditure. Especially, this study analyzed the influence of financial management characteristics. For this, the income level is classified by comparative poverty and analyzed the influence power The data for this study was "the Korean Labor Panel" conducted by Korea Labor Institute in 2000. The result showed the demographic factors by the income level and financial characteristics have big difference. Also, income level affects private education expenditure. For lower income level, demographic factors affect more than financial factors. This result explained the private education expenditure as luxurious goods. For middle income level, financial factors affect more than demographic factors. This explained the private education expenditure as choice goods. For upper income level, the private education expenditure was explained as investment goods.

Using 8,499 observations from 5 years-1,878 firms panel data during 2014 to 2018 in Korean stock exchanges, this study examines the impact of National Pension's ownership on corporate philanthropic giving. The empirical study finds that National Pension's ownership has positive relations with the extent of corporate philanthropic giving in terms of the amounts per employee, the expenditures with respect to total asset and total sales, implying that National Pension plays a monitoring role in promoting target firms to increase the extent of corporate philanthropic giving, which lead to increase in target firms' long-term values. The empirical study also finds that when National Pension is a blockholder holding more than 5% ownership in the target firms, it has positive relations with the extent of corporate philanthropic giving in terms of the amounts per employee, the expenditures with respect to total asset, implying that it exercises disciplinary roles on focal firms in promoting the extent of corporate philanthropic giving in order to increase target firms' long-term values. The results overall support that National Pension plays positive effects on target firms in promoting the extent of corporate philanthropic giving, which lead to increase in target firms' long-term values.
