Korea Health Panel Survey (KHPS) has been conducted to provide nationally representative estimates of health care use and expenditures for non-institutionalized population in Korea since 2008. The aim of this study was to present estimates from KHPS on dental utilization and expenditures from 2008 to 2011. While weighted estimates were presented for each year from 2008 to 2011, the focus of this study was on the 2011 estimates and changes in dental utilization and expenditures between 2008 and 2011. Weighted estimates were obtained using population weights and statistical significances were analysed by independent t-test or ANOVA test using SPSS version 20 for Windows. In 2011, 21.1% of Korean population obtained outpatient dental services from dentists. From 2008 to 2011, the percent of people with a dental visit in each year increased slightly. In 2011, the mean number of dental visits was 4.46. While the mean number of dental visits remained stable by 2010, it increased slightly in 2011. The total annual dental expense in 2011 for people with a visit was about 460,000 Korean Won and 10% higher in 2008. In summary, this study results highlight low rates of dental utilization and high dental expenses in Korean population.

The purpose of this study was to examine dental care utilization and expenditures among children aged 0 to 19 years using Korea Health Panel Survey (KHPS) data in 2008 - 2013. Weighted estimates were nationally representative and statistical significances were analysed by $x^2$ test or adjusted Wald test using STATA 13 software. While dental care utilization increased steadily among children from 2008 through 2013, less than one-third the children received dental care in 2013. Compared with 2008, the proportion of restorative care, oral surgery, preventive care decreased and the proportion of orthodontic care, prosthetic care increased. While the proportion of amalgam markedly decreased, the proportion of resin increased. This study highlight socioeconomic disparities in dental utilization and expenditures among children. Especially the findings provide a baseline assessment for examining trends on dental care for children in the future.

Objectives: The objective of this paper was to estimate a South Korean's lifetime dental expenditures for periodontitis. Methods: For our study, we collected data from the Korea Health Panel Survey (KHPS), from 2010 to 2016. The outpatient dental care data of 1,919,608 samples of periodontitis were extracted using R version 3.0 and estimations of lifetime dental expenditures for them were generated using Excel. Results: Over 50% of the lifetime dental expenditure of South Koreans was spent for periodontitis, and incurred after the age of 40. The results showed that an estimate of average per capita lifetime dental expenditure for men (approximately 13 million won) was greater than that for women (approximately 8.8 million won) for periodontitis. Conclusions: Efficient methods for the prevention and management of periodontitis are necessary, and a new paradigm of health care system is required to reduce dental expenditure through its prevention.

In this study. we present a modified rational addiction model which incorporates social-psychological factors. This is done through a utility function which includes social-psychological factors as its component. We apply this model to a cigarette consumption function in Korea using the data from the Korean Household Panel Study(KHPS). The results provide relatively strong support for the rational addiction model. However. the impact of social-psychological factors and the short-run and long-run price elasticities are statistically insignificant.

The purpose of this study were 1) to identify housing consumption over family life cyle and 2) to analyze the propensity of residential mobility and its contributing factors over family life cycle. For these purposes the 1993 KHPS data was used. The sample in this study consisted of 2,796 couple households. Satistics employed for the analysis were frequencies means and logistic regression analysis. As the number of children and the children's age increased the housing consumption increased. There were many factors such as husband's education satisfaction of health and family relations monthly income wealth debt owning a car home ownership duration of residence and the satisfaction with housing contributing to housing consumption and propensity to move. Those with home ownership higher wealth higher satisfaction with health higher expenditure, longer duration of residence and higher satisfaction with housing tend to move more frequently. However those with low educational attai ment less satisfaction with family relation less income and having no debts were likely to move.

Analyzed data was the KHPS (Korean Household Panel Study) which was collected by Daewoo Economic Research Institute. Subjects were 646 husbands and wives. Results were as fellows: 1) The family business was preferred by the middle age than younger one. In many cases, size of the family business was smart, but variation was relatively large. 2) Wives'satisfaction with family living was lower than husbands'one. Differences between wife's and husband's satisfaction with occupation were not appeared. 3) As couples'one were younger, as the satisfaction with health and couple's relationships were higher. Especially frequency of the out of meal and vacation experience in the last year were important variables in the satisfaction with family living.4) Frequency of the out of meal was important variable in the explaining the satisfaction with the income, stability, and a bright future of the family business.

The purpose of this study was to investigate factors affecting consumer's housing tenure status by various household's characteristics. This study used 1997 KHPS(Korea Household Panel Study) by Daewoo Economic Research Institute and used 1,977 households for the analysis. The results of this research were summarized as follows; 1. There were major differences in household's characteristics by consumer's housing tenure status, except for the household's monthly income and savings. 2. Factors affecting consumer's choice of ‘owning’ a housing and taking a ‘chonsei’ system were very similar, but they affected in the opposite direction. 3. Factors affecting consumer's choice of taking a ‘chonsei’ system and ‘renting’ a house were much more similar, and they affected in the same direction. This study can be useful in developing housing service and design, and housing policy by consumer's choice of housing tenure status.

This paper tests existence of precautionary saving motive under health uncertainty, using household level panel data from Korea. For this purpose, this paper considers a dynamic health capital model with health uncertainty and derives testable equations for changes in consumption and medical expenditures. Under this framework, households who face future health uncertainty will exhibit precautionary behavior by depressing consumption or increasing investment in health. To test this hypothesis, the paper uses the conditional variance of health as the direct measure of health uncertainty, obtained by estimating a multinomial logit model. Empirical results using the Korean Household Panel Study (KHPS, 1993 - 1997) suggest that Korean elderly households follow the precautionary behavior to insure against future health risk.
