This paper intends to test the non-linear relationship between $CO_2$ emissions and income by employing cointegration model of the time-varying income elasticity. We select France, UK, Italy, Japan, US, China, India, Mexico and Korea and use non-parametric time series analysis on each country in order to estimate its own effect of income on $CO_2$ emission. The main results indicate that the $CO_2$ emission-income elasticities vary over time and the income elasticities of the Annex I countries tend to be higher in absolute terms than those of developing countries. In addition, we find that emission-income elasticities decrease for Annex I countries over time, whereas those for developing countries increase.

This study analyzed whether depression and social support had a mediating effect between income status and life satisfaction of middle-aged and elderly people with disabilities using data from the 15th year of the Korea Welfare Panel data. As a result of the analysis, first, the income status of the middle-aged and disabled was depressed(B=.241, p<.001), social support(B=-.167, p<.001), and life satisfaction(B=-.277, p<.001) was confirmed to have a direct effect. Second, the mediating effect of depression and social support was verified on the influence between the income status of middle-aged and disabled people between life satisfaction. Third, it was confirmed that depression and social support had a multi-mediating effect between the income status and life satisfaction of middle-aged and disabled people. Therefore, an income support system that supports middle-aged and disabled people to live at an appropriate level should be prepared. In addition, in order to increase the life satisfaction of middle-aged and disabled people, it is necessary to intervene in mental health support services that can actively cope with depression and to expand the social support network.

Differences in socioeconomic status (SES) such as income levels may partly explain why breast cancer screening (BCS) disparities exist in countries where health care services are free or heavily subsidized. However, factors that contribute to such differences in SES among women living in well resourced Middle East countries are not fully understood. This quantitative study investigated factors that influence SES and BCS of Arab women. Understanding of such factors can be useful for the development of effective intervention strategies that aim to increase BCS uptake among Arab women. Using data from a cross-sectional survey among 1,063 Arabic-speaking women in Qatar, age 35+, additional data analysis was performed to determine the relationship between socioeconomic indicators such as income and other factors in relation to BCS activities. This study found that income is determined and influenced by education level, occupation, nationality, years of residence in the country, level of social activity, self-perceived health status, and living area. Financial stress, unemployment, and unfavorable social conditions may impede women's participation in BCS activities in well resourced Middle East countries.

The purpose of this study is to provide basic information on exporter's coordination methods from the attitude of agro-food exporters. The implications are; Firstly, most of exporters believe that the agro-food export raises farmer's competitiveness rather than it does the farmhouse's income increase. Secondly, The stabilization of the farm-gain income by exporting agricultural products are most important in order to reinforce the cohesion between farmers and exporters. Thirdly, the exporters intend to participate in establishing and operating a large-scale producers' organization and marketing company under export polices. So, it is necessary that the government drive to coordinate the exporters and producers.

This study analyzes the effect of demographic changes on economic growth. We use the supply-side output identity to forecast the growth potential of the Korean economy. According to the results, even based on optimistic assumptions and prospects, the economic growth rate is likely to fall drastically starting in 2020. Of course, to maintain growth potential, efforts to increase productivity are necessary. However, given the historical experience of developed countries, it is not clear whether the huge trend of demographic change can be offset by efforts to increase productivity. In the so-called '30-50 club' countries, both labor productivity and growth rate tend to fall after reaching the per capita income of $30,000. The degree of decline in the growth rate is closely related to changes in the working age population and the prime-age workforce. The results are similar when tracking the path of changes in total factor productivities of the economy. When a certain level of income is reached, the increase in total factor productivity also tends to slow down. The ripple effects of rapid changes in demographics will indeed be extensive. The negative impact is likely to be concentrated at a time when the working age population, the prime-age workforce, and the total population shrink simultaneously. Above all, it is necessary to use the government's fiscal space to block the possibility of a rapid fall in the growth rate. In addition, it is important to continuously implement various reform tasks that should be promoted, such as improving the education system and strengthening the social safety net.

Objectives: The importance of kimchi as a traditional food in Korean cuisine has gradually decreased due to rapid industrialization, economic growth and changes in dietary patterns in Korea. This study aimed to examine the shifts in kimchi consumption by region and by income level between 2005 and 2015 in Korea. Methods: Data from the Korea National Health and Nutrition Examination Surveys III (2005) and VI (2015) were used in the study (n=15,558). Intake of kimchi was estimated using a single 24-hour dietary recall. The sample weights were applied in all analyses to reflect population estimates. All statistical analyses were carried out by using SPSS IBM Statistics 20. Results: Kimchi intake has significantly decreased by 27.6 g/day per capita during the last decade in Korea; 25.0 g for males and 29.9 g for females, respectively. Over the past decade, the decline of kimchi intake has been particularly significant in Seoul, Busan, Incheon, Gyeonggi, and Gwangju, while there has been no significant change in males living in rural areas. The consumption of kimchi across all income levels has decreased, however, the decrease was higher in 'middle and low income level'. The amount of kimchi consumption in 2015 was the highest in 'low income level'. The results were similar after adjusting for gender and age. Conclusions: For the past decade, the overall intake of kimchi in Korea has decreased, however, it has been found that the decrease of kimchi intake for males living in the rural areas was not significant. Therefore, in order to keep our traditional kimchi culture and promote a balanced diet including kimchi for Korean, it is necessary to develop more efficient policies and approaches. A variety of dishes using kimchi should be developed, besides merely serving kimchi with rice as a side dish, to increase the consumption of kimchi.

The purpose of this study is to examine the effects of household income types and sources on the depressions and self-respect of the old aged. Although household income types and sources are supposed to be important to the mental health of the old aged as well as income level, there have been little policy interests to them. This study analyze the relationship between the household income types & sources and the mental health of the old aged, using the 8th data from the Korean Welfare Panel Study. Major findings are as follows. First, we find that there are considerable variations in the household income sources composition among the old aged, and that types of household income are related to the individual and family features of the old aged. Second, the results of regression analyses show that the household income types are associated with the depression and self-respect of the old aged. And, we find that some income sources affects the mental health of the old aged. The results of this study suggest that there should be policy attentions to the mental health effects of the household income sources so as to increase the adequacy of the income security system for the aged in Korea.

BACKGROUND/OBJECTIVES: The study objectives were to examine the participation rate in food assistance programs and explore the factors that contribute to such participation among the Korean elderly population. SUBJECTS/METHODS: The study sample comprised 3,932 respondents aged 65 years or older who were selected from a secondary data set, the fourth Korean Welfare Panel Study (KoWePS). The factors, related to participation in programs were examined based on the predisposing, enabling and need factors of the help-seeking behavior model. Multiple logistic regression analysis was used to select the best contributors among the factors related to program participation. RESULTS: The predisposing rate in food assistance programs was 8.5% (7.1% for men and 10.4% for women). When all variables were included in the model, living without spouse, no formal education, low income, having social security benefits and food insecurity in elderly men, and age, low income, having social security benefits and feeling poor in elderly women were significantly related to a higher tendency to program participation. CONCLUSIONS: The predisposing and need factors, such as living without spouse, low education level, food insecurity and feeling poor were important for program participation, as well as enabling factors, such as household income and social security benefits. A comprehensive approach considering these factors to identify the target population for food assistance programs is needed to increase the effectiveness and target population penetration of these programs.

Korean population is ecpected to reach about 50 million by year 2000. And per capita GNP might attain the $5,000 level. This is bound to have profound impact on housing. For one thing, population and income growth will accelerate new household formation thus increasing new housing needs. On the other, changes in the housing preference function in association with income growth and new way of life would mean increasing demand for better dwelling environment. In addition, by year 2000, there will be many more elderly households necessitating new approaches to housing. The question is whether or not Korea could cope with new housing perspectives. If Korean housing has made in the past some progress in housing quality, it has not been able to tackle the mounting housing shortage. This is attributable to the concentration of effective housing demand in the hands of upper income groups in association with skewed income distribution and sustained dwelling price hike. Korea needs some basic changes in housing policy. The public sector should produce much more small dwellings either for sales or renting. Second, mortgage loans should be expanded so as to increase the access to housing. Third, every thing must be done to cut down the dwelling price through tax cut, relaxation of some requlations, cyclical stabilization of dwelling construction and loan subsidies.

The food self-sufficiency rate of agricultural products in Korea, excluding rice, is around 20%, and the government is promoting various policies including a Multiple-Purpose Utilization of Paddy Fields project, to increase the self-sufficiency rate of major grains. The project for Multiple-Purpose Utilization of Paddy Fields is being promoted as a part of a program to create farmland infrastructure to facilitate the cultivation of crops other than rice in rice paddies, and pilot projects were started in four regions in 2020. The purpose of this study is to analyze the economic effects of the pilot project for Multiple-Purpose Utilization of Paddy Fields, and to propose policies to increase the effectiveness of the project. In order to analyze the economic effect, we estimated the change in farm income generated by switching from rice to other crops, and measured the effect of welfare change using the Equilibrium Displacement Model (EDM). As a result of the analysis, social welfare is expected to increase when the pilot project for Multiple-Purpose Utilization of Paddy Fields is implemented, and the income of the beneficiary farmers is also expected to improve compared to that of single-cropping when double-cropping is implemented. However, it was found that the economic feasibility of the project differs depending on the crops converted. Juksan-myeon, Gimje-si, which is an area where soybean production was successful, was analyzed from the viewpoint of increasing the economic feasibility of the pilot project. Their success factors were analyzed into four major factors: infrastructure, farming methods, education, and collaboration with local agricultural organizations. If such a success story can be utilized in the future project implementation process, it can contribute to the improvement of farm household income and national economic welfare.
