Private education expenses is one of the key issues in Korea and there have been many discussions about it. Academically, most of previous researches for private education expenses have used multiple regression linear model based on ordinary least squares (OLS) method. However, if the data do not satisfy the basic assumptions of the OLS method such as the normality and homoscedasticity, there is a problem with the reliability of estimations of parameters. In this case, quantile regression model is preferred to OLS model since it does not depend on the assumptions of nonnormality and heteroscedasticity for the data. In the present study, the data from a survey on private education expenses, conducted by Statistics Korea in 2015 has been analyzed for investigation of the impacting factors for private education expenses. Since the data do not satisfy the OLS assumptions, quantile regression model has been employed in Bayesian approach by using gibbs sampling method. The analysis results show that the gender of the student, parent's age, and the time and cost of participating after school are not significant. Household income is positively significant in proportion to the same size for all levels (quantiles) of private education expenses. Spending on private education in Seoul is higher than other regions and the regional difference grows as private education expenditure increases. Total time for private education and student's achievement have positive effect on the lower quantiles than the higher quantiles. Education level of father is positively significant for midium-high quantiles only, but education level of mother is for all but low quantiles. Participating after school is positively significant for the lower quantiles but EBS textbook cost is positively significant for the higher quantiles.

This paper examines the effect of private tutoring expenditures on academic performance of middle school students in South Korea, using data from "Analysis of the Level of School Education and Its Actual condition: Middle School". In the face of endogeneity of private tutoring expenditures, the paper employs an instrumental variable (IV) method and a nonparametric bounding method. Using both methods we show that the true effect of private tutoring on middle school students remains at most modest in Korea. The IV results suggest that a 10 percent increase in tutoring expenditure for Korean, English and math raises a student's test score of the subject at the largest by 1.24, 1.28, and 0.75 percent, respectively. The bounding results also fail to show evidence that an increase in tutoring expenditure leads to economically and statistically significant improvements in test score.

In this study, we used the Korea Health Panel Study for 2017 raw data as analytical data to understand the factors that affect the catastrophic health expenditures of the baby boomer generation and the final number of analyzed was 808 people. Analysis methods performed frequency analysis, crosstabulation, and multiple regression analysis, with p = .05 at the significance level for all validations. The statistically significant differences among the baby boomer generation were education level, marriage status, health insurence, household income, drinking, smoking, subjective health, outpatient care, and inpatient care. The average number of illnesses in the baby boomer generation was 8.14, of which 7.97 for male and 7.97 for female. The average number of outpatient visits was 16.81, of which 14.81 recalls for male and 26.89 for female. More than 40% of the ability to pay the catastrophic health expenditures rate was 15.3% for male and 26.3% for female. The factors affecting the catastrophic health expenditure of babyboomer generation are as follows. that influence the widow's fence medical expenses are as follows. Male were private insurance, household income, drinking, and inpatient care, and female were private insurance, household income, and drinking.

The objective of this paper is to analyze expenditure structures and impact factors of household's transportation cost in order to provide policy-maker with quantitative and economic information for reducing household's transportation costs, using 1995-2007 household survey data. For this purpose, this study performed various economic analysis, including econometric regression analysis and income re-distributional effects. The four models were separately estimated with dependent variable (personal and public costs, public transit and private car costs) and independent variables (family, employ, age, education, cars, household income, region dummy variable). In addition, We analyzes impacts of transport policy instruments on the transportation expenditure. These instruments include changes of oil price and public transit fare, reform of public transport system, and extension of subway facilities. Finally, income re-distributional effects before and after transportation expenditure, using Pechman-Okner (PO) index and Wolfson index.

Background: This study purposed to compare the difference on medical utilization and health expenditure of baby boomer generation by depression between gender. Methods: Korea Welfare Panel Survey 2016, provided by the Korea Institute for Health and Social Affairs, was used for the analysis. For the research, we used the two-part model, yes or no of use (part 1), and frequency of use (part 2) for medical utilization. The dependent variables are the whether or not to use of hospitalization services, outpatient services, length of stay, outpatient service visits, and health expenditure. And the independent variables are used as the predisposing (education, spouse presence), enabling (insurance type, private insurance, economic activity, income), and need (chronic disease, self-rated health, disability) factors in the Andersen behavior model. Depression was used as intervening variables. Structural equation model and multiple group analysis by gender were used. Results: There were differences in the medical care usage and cost between men and women in baby boomer. For men, mediating effects of depression were present at the hospitalization (yes/no), length of stay, and health expenditure. On the other hand, for women, the mediating effect of depression was found only at the outpatient visits. Specially, depression was working at the medical services by the different way between gender. The size of effect (multiple group analysis) was affected by significant differences between men and women. Conclusion: This study found that the mediating effect of depression is increased medical usage and health expenditure and the effect factors are different by gender. Therefore, it is necessary to establish a medical care policy considering the socio-economic characteristics of baby boomers.

Since the introduction of mandatory health insurance in In, the Korean national health insurance(KNHI) has grown rapidly. In 2004, about $96.9\%$ of the total population are covered by the KNHI and the remaining $3.1\%$ by the Medical Aid program. Despite national health insurance system in Korea, private health insurance market has grown rapidly. In 2004, the size of the private health insurance market was estimated at 6,568 billion won. The purpose of this study Is to identify the factors that determine the purchasing decisions of supplementary private health insurance under mandatory national health insurance system in Korea. The data from n04 Busan Health Survey were analysed for the Purpose. The variables in this study are demographic factors, health status and health behavioral factors, health care systemic factors, and socioeconomic factors. For statistical analyse, we used logistic regression. The Findings show that female, economically active age group(especially 35-49 years), persons with better health status or experience of health screening test are more likely to purchase private health insurance. And higher household income and expenditure, higher education level are more associated with the increased probabilities of private health insurance purchases. This results imply that the expanding of private health insurance market could widen the gap between the have and have-not in terms of equal health care accessibility.

Purpose: The purpose of this study was to investigate determinants of purchasing indemnity private health insurance and its impact on the healthcare utilization among outpatients with chronic disease. Methods: The study analyzed 4,997 chronic ill patients using 2015 Korean Health Panel data. Logistic regression analysis was conducted to analyze the factors affecting the purchase of indemnity private health insurance and multiple regression analysis was conducted to analyze the effect of private health insurance on the number of outpatient visits and outpatient expenditures. Findings: The age, education level, and number of chronic diseases were significant factors affecting the purchasing of indemnity private health insurance among chronic patients. As a result of analyzing the impact of indemnity private health insurance on healthcare utilization, the number of outpatient visits for those who enrolled in the indemnity private health insurance was higher than the number of outpatient visits for those who did not. But there was no statistically significant difference in outpatient medical expenses. Practical Implications: The results of this study shows that indemnity private health insurance may cause inequality in the healthcare utilization of the socially vulnerable. It is necessary to seek ways to strengthen the health security of chronic disease patients and high-risk elderly people who need more healthcare.

The purpose of this study is to analyse the change of consumption structure of households due to spending on private tutoring, then analyse the difference of change depending on income bracket. The results of the study show that the proportion of private tutoring spending of poor households is relatively higher than high or middle income households although the amount is smaller than them. The consumption items adjusted by the change of private tutoring spending are different depending on income level, and adjustment possibility of them of poor households is very lower than other classes. These show their risk of insufficient consumption of food, clothing, and shelter is high. The burden of private tutoring spending of the poor increase the economic insecurity, therefore various supportive approaches such as improvement of the quality of public education, economic support the poor suffering from the burden of private tutoring spending are necessary to prevent the latent problems of the poor and their children.

In this paper, we configured the panel data of four years using the information of Higher Education In Korea (2010~2013) and studied the influence of tuition and scholarships on the stop-out rate of national university and private university separately through a panel analysis. Three models are implemented considering various variables suck as faculty-student ratios, employment rate, per pupil expenditure, average tuition, and per pupil scholarship. This study showed that the lower net tuition and the higher per pupil off-campus scholarship lowered the stop-out rate at national universities and the lower tuition and the higher per pupil scholarship lowered the stop-out rate at private universities.
