The objective of this paper is to construct pseudo-panel data set and estimate price and income elasticities of car travel demand, using 1995-2007 household income and expenditure survey data, in order to provide quantitative information for analyzing related policy effects in the transport sector. We categorized household survey data into 14 cohorts based on the birth year of the household head. As the result, a total of 133 pseudo-panel data sets was created for estimating price and income elasticities of car travel demand. Especially, price and income elasticities of car travel demand were separately estimated both short-term and long-term. We analyzed the panel model considering fixed effect within cohorts, using explanatory variables such as previous year's fuel consumption, real household income after tax, education level of the household head, the number of children under five, and the share of household type averaged by cohorts. As results, the short-term and long-term price elasticities of car travel demand were calculated as 0.2974-0.4280 and 0.4087-0.6275, respectively. Similarly, the short-term and long-term income elasticities were calculated as 0.3364-0.6281 and 0.7098, respectively.

Aggregate income stability depends heavily on labor market institutions that stabilize or de-stabilize earnings. But, with the expansion of sate welfare programmes, public income transfers are also important sources of income stability for individual and families. Moreover, income stability is determinant factor of individual and family well being, there are another strategies of income stability in society. Family-based and community-based strategies are particularly important. Accordingly, the distribution of income stability in a given society depends on such institutional arrangements as market, family, state, and community. The purpose of this study is to analyse the income stabilizing role of family, state, and community. I found that stabilizing effect of the family and community was very strong in Korea. When institutional features of labor market and the state leave individuals exposed to market risk, they may be respond by relying more on family-based or community-based strategies of income stabilization. But, I can't deny the possibility of an inadequacy of these strategies in according to the rapid changes of family structures and informal networks. Therefore, state-based strategies of income stabilization should be more strengthened in Korea.

This study focused on real estate rental income, which is being interested as a means of preparing for old age in the age of low growth and aging. Rental income is seen to function as a safety net of society at a time when it is necessary to live a difficult old age due to the disconnection of income and the extension of the average life span. Therefore, this study conducted the following study on 1,025 households that own rental real estate nationwide. First, the relationship between the characteristics of the household of the rental real estate owner and the real estate rental income was analyzed, and second, it examined whether there is a difference in rental income between the group that engages in income activities other than rental income and the group that only has rental income without income activities. As a result of the analysis, among the demographic and sociological characteristics, gender and spouse were identified as significant variables in rental income. Among the economic characteristics, income and total debt were found to be significant variables. In the case of income activities, rental income was low, and rental income was high when the total debt was high. However, if interest rates rise and the economic recession is prolonged due to unpredictable causes, the owner may suffer from double-use. In preparation for this, it is necessary to review real estate policy alternatives such as easing the period of real estate holdings.

The purpose of the study is to analyze the housing problems of single-person household in 20-35 age group. Using the survey of Household's Consumption in 2014, we estimated the housing demand function of young single-person household in Seoul. As a result, the coefficient of the permanent income for young single-person household housing was significantly lower than other groups and the housing demand was also lower than others. Since current income isn't come up to permanent income enough, the housing consumption of young single-person household shrinks. It implies the role of the housing financial market is less activated. That is, the difficulty of realization of permanent income and lack of housing finance are the main cause of the imbalance of housing demand of one young person. Therefore, it implies that in order to alleviate the housing problem of the young single-person household, a policy to balance the permanent income with the housing demand is needed.

The objectives of this study were to analyze the socio-economical factors related to smoking and drinking behaviors using the Korea Welfare Panel data. The key variables were sex, age, frequency of health and medical facilities visit, subjective health level, smoking level, drinking level, depression symptoms, and low income level. Since the health variables in the Welfare Panel data were limited, the analysis was exploratory. In male population of those older than 30 years old, low income group people were more likely to smoke cigarettes than the general income population. In the result of the Chi square analysis, the smoking rate showed significantly different relationships with the different age groups, gender and income level. According to the descriptive analysis, persons with low income level were more likely to experience health risk behaviors and showed more medical service utilization. The utilization of the local public health centers was 4.6% for the Bow income level and 1% for the general level. The higher smoking rate was associated with the younger age, and the lower income. The smoking rate in the age category from 20 to 29 was 23.3% for the general level and 25% for the low income level. On the other hand, the drinking rate was even higher in the general families. The rates of non use of alcohol was 36.7% in the general families and 58.4% for the low income families. For both smoking and high risk drinking issues, demographic and sociological variables such as sex, age, education levels and income levels were analyzed, and there wer significant relationships. Health risk factors were serious for males, with age groups of 20's and 30's, lower education level, and in a low income family. In general, females were more unhealthy. The rates of smoking and drinking were higher in the low income level. Even in the health and nutrition survey results in 2005, persons in the low income class were experiencing poorer health in health level or the degree of action restriction. Since the effects of the health promotion could not be measured in a short period of time, it has not been easy to create the basis for the substantial effects. Factors related to health risks needs to be continuously studied using data from diverse field.

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.

The purpose of this study is to examine the moderating effect of social capital in regards to the influence that family income and job status have on the level of satisfaction with family relationships among married immigrant women. We conducted the second analysis of "2009 National Survey of Multicultural Family State" and used moderated regression analyses. Controlled variables included age, education level, offspring status, and Korean proficiency, while independent factors included family income and job status. Moderating variables of social capital included trust, participation, and network. The results showed that all the demographic variables, as well as family income and job status, had significant influences on married immigrant women's satisfaction with family relationships. In particular, when factors of social capital interacted with family income and job status, the study showed that it had a different influence on the satisfaction with family relationships. Moreover, the moderating effects have been shown to be more certified through its comparison of the increasing and decreasing trends of social capital. This research has been shown to be significant, based upon the findings on moderating effects of social capital in respect to married immigrant women's level of satisfaction with family relations. Practical implications of our results in the context of social welfare were discussed.

건강관련 요인에 따른 우리나라 성인 여성의 영양섭취 특성을 파악하기 위해 2001 국민건강ㆍ영양조사-영양조사부문의 결과를 심층 분석하였다. 2001 국민건강ㆍ영양조사는 2001년 11월 1일부터 12월 31일까지 전국 200개 지역에서 약 4,000가구, 14,000명을 대상으로 실시되었으며, 본 연구에서는 응답자 중 20세 이상 성인여성 3,780명의 데이터만을 활용하였다. 이들의 연령, 소득수준, 건강 인식도, 비만도 및 체중인식 등에 따른 영양소 섭취수준을 비교하였으며, 평균값의 차이에 대한 유의성 검증에는 1-way ANOVA와 Duncan's multiple range test를 적용하였다. 분석의 대상이 된 성인 여성 응답자의 구성은 20∼29세가 696명, 30∼49세가 1,765명, 50∼64세가 757명, 65세 이상이 562명이었다. 20세 이상 모든 성인 여성의 영양소별 영양권장량에 대한 평균 섭취수준을 보면 칼슘의 경우에 67%로 가장 낮았으며 다른 영양소의 경우에는 권장량에 근접하는 것으로 나타났다. 그러나 연령층별로 비교하면 철의 섭취수준은 20대 여성에서 가장 낮은 반면, 나머지 영양소의 섭취 수준은 65세 이상 연령층에서 가장 낮았다. 2001년 가구원 수 별 최저 생계비를 기준(100%)으로 하여 가구소득을 100% 미만, 100∼199%, 200∼299%, 300% 이상 4 구간으로 분류한 소득수준에 따른 영양소 섭취수준을 비교한 결과, 전체적으로는 소득수준이 높아질수록 평균 영양소 섭취수준이 높아지고, 가구 소득이 저생계비 미만인 그룹에서 거의 모든 영양소의 섭취수준이 가장 낮게 나타났으나, 55세 이상 연령층에서는 소득수준이 영양소 섭취 수준에 영향을 미치지 않았다. BMI를 기준으로 저체중군, 정상체중군, 과체중군으로 분류한 비만도 그룹별 영양소 섭취수준을 비교한 결과, 전체적인 영양소의 섭취수준이 정상체중군에서 높고 저체중군에서 가장 낮았으며, 특히 65세 이상 연령층의 저체중군의 섭취수준은 매우 낮아서 칼슘과 비타민 A의 경우 권장량의 40% 대에 불과했다. 자신의 체형에 대한 인식에 근거해 영양소 섭취수준을 비교해 보면, 20대에서는 자신이 말랐다고 인식하는 그룹에서 섭취수준이 다소 낮게 나타났으나 30∼49세에서는 말랐다고 인식하는 그룹의 영양소 섭취수준이 오히려 높은 것으로 나타나 연령에 따라 다른 경향을 보였다. 건강 인식도에 따른 분석 결과, 스스로가 건강하지 못하다고 생각하는 그룹에 비해 건강하다고 인식하는 그룹에서 철을 제외한 모든 영양소의 섭취수준이 유의적으로 높게 나타났다. 이상으로부터 우리나라 여성 중 65세 이상 노인과 최저생계비 미만의 저소득 가구 여성의 영양소 섭취 수준이 심각하게 낮으며, 소득 수준 차상위 계층(100∼199%) 여성의 섭취 상태도 관심을 기울여야 할 수준임을 알 수 있었다. 동시에 자신의 건강이나 체형에 대한 인식이 부정적일수록 섭취수준이 불량하여 한국 여성의 건강과 올바른 영양관리를 위해서는 여성 스스로의 긍정적인 사고 또한 중요한 영향 요인인 것으로 나타났다.
