This study aims to analyze panel data using OECD Health data of 34 years to examine how significant the inequality of income is to the inequality of health. The data was from OECD's pooled Health data of 32 countries from 1980 to 2013. The process of determining analysis model was as follows; First, through the descriptive statistics, we examined averages and standard deviation of variables. Second, Lagrange multiplier test has done. Third, through the F-test, we compared Least squares method and Fixed effect model. Lastly, by Hausman test, we determined proper model and examined effective factor using the model. As a result, rather than Pooled OLS Model, Fixed Effect Model was shown as effective in order to consider the characteristics of individual in the panel. The results are as follows: First, as relative poverty rate(${\beta}=-19.264$, p<.01) grows, people's life expectancy decreases. Second, as the rate of smoking(${\beta}=-.125$, p<.05) and the rate of unemployment (${\beta}=-.081$, p<.01) grows, people's life expectancy decreases. Third, as health expenditure(${\beta}=.414$, p<.01) shares more amount of GDP and as the number of hospital beds(${\beta}=-.190$, p<.05) grows, people's life expectancy increases.

A recent study conducted by KOTI reported that regional and urban read congestion costs in Korea are continually rising in the ranges between 3.1% thru 4.1% of GDP in the every respective year during the past 10 years. The report explicates that the congestion problem has motivated sharp raise of the logistics expenditure from 4.4% of GDP in the year of 1998 to 16% in the year of 2003. Even though, the government has allotted annual budget in the ranges between 2.7% and 3.7% of GDP to the SOC investment for the consecutive years of past decade, the amounts are however far less and insufficient to meet with social requirements and its demands. The cost of logistics has been excessively went up much higher rate than that of other industries and that of 9.6% in Japan and United States respectively It is obvious that the high logistics cost could be a detrimental factor to fierce emulation with others in the global trade market. Therefore it is an essential matter to eliminate or exclude all the probable sources that might cause or create extra costs on logistics. In consideration of such situation in Korea, the SOC investment with private capital could be a best cogitable scheme to acquire its prompt demand solutions and stimulate the emulation ability in the international trade market what's more betterment for all of our quality life in the near future.

This study was performed to investigate the type perceived risk of clothing consumers and the types of information seeking, the relationship between perceived risk and information seeking, and the defferences according to the demographic variables. The surveyed data from 376 college students were analized using Person's correlation, factor analysis, t-test, and ANOVA. The risk perception of clothing consumers was classified into five types: economic and performance risk, loss of time risk, social risk, and loss of fashionability risk. The information seeking was classified into four types: advertisement, observation in shops, information in memory, and opinions of neighbors. The type of risk perception and the types of information seeking were correlated positively and were different according to expenditure on clothing.

The purpose of this study was to examine factors related to the purchase of cash-value life insurance of households. Based on human capital and bequest motive theories of the demand for life insurance, this study developed a conceptual model of the demand for life insurance of households. In addition, in order to capture the beneficiaries' preference and expected lifetime utility, expected future financial needs were included in the conceptual model. Using Heckit analysis, the model was estimated by two stages. The results supported that human capital, bequest motives and expected future financial needs were significant factors on both decision to have insurance and the mont of insurance. Specifically, if the household's head expected to have a higher potential in the future, the household was more likely to have insurance. If a household had dependents, the household was more likely to have insurance. As income or monthly expenditure increased, the probability of haying insurance and the amount of the insurance increased However, savings or social insurance were positively related to the purchase of insurance.

The interest and expenditure for children is increasing than in the past because the number of nuclear family is growing, the children's space is configured independently in most homes from infancy, therefore, the market of children's furniture is expanding in spite of the reduction in the population of children. There are not many products considering age, gender, and play behavior in children's furniture market in Korea. The bed, desk, chair, and closet for children under 2 years hold a large majority of children's furniture, there are not a lot of preschool children's furniture for the children aged 4 to 7. As the children aged 4 to 7 experience physical, emotional, and cognitive growth at the same time, the space configuration and furniture choice for these children is educationally very important. Therefore, in this study, we present the importance and necessity of playable furniture to promote the physical, social, emotional, linguistic, and cognitive development of the children aged 4 to 7 among preschool children. We found the concept and basic condition of playable furniture to collect the base data for developing playable furniture and provided the basic data for the development of an ideal playable furniture by comparing and analyzing the cases of 157 items of 14 domestic playable furniture companies and 365 items of 30 overseas in aspect of play functions, forms, materials and colors.

This study examined the subjective health recognition, motivation, selection property, consumption realties, and generalities of elderly people eating out. The ratio of women eating out in those over 60 years of ages was high and people in that age group ate out most actively. The score of convenience-oriented, gourmet-oriented, and dignity-oriented of the selection property for eating out increased with increasing frequency and expenditure for eating out. With increasing age, a negative (-) relationship with a decrease in the safety-oriented score of the selection property for eating out was predicted. As the number of days eating out increased, a positive (+) relationship with an increase in the safety-oriented score of the selection property for eating out was observed. As the scores of physical and social health perception increased, a positive (+) relationship with an increase in the gourmet oriented score was observed. Based on the results, various research on the relationship between the health recognition and eating out behavior of those over 60 years of age are required.

Despite the numerous advantages that CSR engagement can potentially offer, top managers may not always be willing to invest in CSR as they are expected to meet expectations of external constituents in the short run. Given that financial analysts' expectations are important short-term performance targets that top managers are motivated to meet, this study examines how performance relative to earnings forecasts issued by analysts affect top managers' decisions about CSR engagement. Using a sample of publicly listed U.S. firms from 2000 to 2016, we find that top managers are more likely to reduce discretionary expenditure on CSR activities as performance falls below analyst forecasts to improve financial performance in the following fiscal year. As performance exceeds analyst forecasts, top managers are motivated to reduce CSR investments in order to meet higher expectations of analysts. As financial analysts closely monitor the firms that they follow in order to publish investment advice to market participants, we find that analyst coverage weakens top managers' incentive to reduce CSR engagement. Overall, this research sheds meaningful insight into the contextual background in which the top managers are situated in when they make decisions on CSR engagement.

Purpose: The purpose of this study is to empirically evaluate the unintended welfare losses induced by paid sick leave, examine the severity of the unintended moral hazard loss caused by paid sick leave, and evaluate how much moral hazard cost society can accept to obtain paid sick leave benefits. Research Design, Data and Methodology: We examine the Medical Expenditure Panel Survey data collected in 2013 and 2014 by employing a panel probit analysis to control for individual heterogeneity. Results: The estimation result shows that the probability of absence due to paid sick leave increases from 4.91% to 7.84%. Among them, excluding the probability of increasing absence from 1.29% to 2.69% due to the actual disease, the probability of absence due to the moral hazard was estimated to be 2.41% to 6.49% in the proposed models. Based on the result, if we evaluate the increase in absence caused by moral hazard as a social cost, the estimated cost is approximately $174 to $297 per worker per year. Conclusion: Considering these expected costs, our society can obtain the access benefit from paid sick leave if we are willing to accept the moral hazard cost.

This study is an empirical research to analyze how many private income transfers in Korea decrease poverty rate, to compare the effects of private income transfers' decreasing poverty rate with income classes. This study has utilised the Family Income and Expenditure Survey to estimate the poverty ratio in urban areas and Unemployment Household Survey which Korea Institute for Health and Social Affairs has investigated at 1998. Majour findins are these. First, Sizes of private transfers incomes are much than that of public transfers incomes. The rates in receiving private transfers income are ten times higher than that in receiving public transfers income among urban worker's household. The mean of private transfer income are about six times larger than that of public transfer income among urban worker's household. Second, the effects of private income transfers' reducing poverty rates are not large. After private transfers, urbarn workers' households are about 10 per cent away from its poverty line, and unemploy households are only 3 per cent away from its poverty line. Third, especially, private income transfers are hardly reducing poverty rates among extreme poverty class. After private transfers, urban workers' households which their incomes are within low 5%, are not away from its poverty line at all.
