In this paper we used the KLIPS(Korean Labor and Income Panel tudy) data that surveyed from 2006(wave 9) to 2009(wave 12). Other previous studies are concerned with the panel attrition in the early wave, but this study classifies the response pattern and investigates some factors that influence panel attrition when the panel tends to stabilize. It was revealed that panel attrition was influenced by relocation and housing type through the logit model. Besides it was appeared that panel attrition was affected by the monthly living expenses and the overall household income through the decision tree.

Background: This study analyzes the effects of the individual's health behavior on the health and the medical demand for the management of health and medical expenses. Methods: This study uses the Korea Health Panel Survey data from 2010 to 2015. We utilize the panel ordered logit model and the panel Tobit model with the subjective health status and the medical expenses as the dependent variables. Results: Chronic diseases would cause the deterioration of his or her health and the increase in medical expenses. Smoking and drinking alcohol would deteriorate one's health. The total amount of cigarettes increases medical expenses. Exercises could make people healthier, whereas excessive exercise might increase medical expenses. Private health insurance would increase medical expenses. Conclusion: Since health could reduce the medical expenses, people should promote one's health by changing one's behavior for health.

It would cause a serious problem in the panel data when panel attrition is concentrated on certain socioeconomic groups. Using the GOMS, this study investigates whether there exists non-random attrition bias in the data and seeks for feasible solutions to minimize the bias. The results of logit analyses show that panel attrition in the GOMS results mainly from surveying system but not from the surveyed. Therefore, the result suggests to develop well-organized management skill and systems as well as to construct weighting methods.

This paper analyzes Korean residential tenure choice for house which is the most important in Korean households' assets. Data used in the analysis is the data of Korean Labor and Income Panel Study for the period from 1998 to 2006 and with 2341 households. In this paper, a household chooses a housing tenure mode, either by renting or by owing house. We use a mixed-logit panel model as an estimation model to take into consideration household's heteroscedasticity of preference in tenure choice. It turns out that the heteroscedasticity is significant in households' tenure choice behavior, implying that Korean housing policy emphasizing supply side should consider the demand side.

This study aims to examine the causality between socio-economic factors and Donate Behaviour. With the 10 years data in Korea Welfare Panel and Panal logit analysis, the analysis has done on the basis of household and sampled 134,500 data. The results of this research as follows: First, in demographic variables, women revealed as they donate more than men(${\beta}=.223$, p<.05). And the more the age grows, the less they donate or volunteer periodically(${\beta}=-.009$, p<.001). Second, in working conditions, paid workers showed less donate behavior than self-employment workers and economically inactive population(${\beta}=-.578$, p<.001). Third, Self-esteem(${\beta}=1.673$, p<.001)and Life satisfaction(${\beta}=1.01$, p<.001) showed significant effect on donate behavior. Lastly, scholarship of father(${\beta}=.211$, p<.001) revealed as significant on donate behavior. However, scholarship of mother did not showed significant effect. Also, the research had some limitations. First, the precision of the variables were not tested. Second, some variables to analyze were not in the data. Therefore, proper considerations on testing the precision of the variables and the method for measuring the missed variables are needed.

The purpose of this study is to analyze the factors influencing poverty in the elderly under the income maintenance, focusing on labor. Accordingly, a Panel Logit Analysis was conducted based on the 7th to 16th data of the Korean Welfare Panel. The analysis results are as follows. First, even if demographic, economic, and health variables affecting elderly poverty are controlled, National Pension and Special Occupational Pension among the income maintenance are negatively related to elderly poverty. On the other hand, it was found that the amount of Basic Pension and National Basic Living Security were positively related to poverty for the elderly. Second, it was found that if the elderly receiving national basic living security work, there is a high possibility of poverty. This raises the need to restructuring the Basic Pension, and suggests that it is necessary to combine the National Basic Living Security with the elderly job policy. Finally, in order to alleviate overall elderly poverty, it is suggested to rebuild the multi-pillar old-age income security system, including Basic Pension and Retirement Pension.

As Korean society grows rapidly older, a systematic analysis of the determinants of labor supply behavior among the elderly becomes a prerequisite for designing more effective senior employment policies and income security regime for the elderly. Literatures review shows that a majority of previous researches have been ignoring the problem of "endogenous predictor" especially when it comes to the estimation of the effects of the two key variables, education and non-labor income, on labor supply decisions among older people. They have failed to take into consideration the unobserved heterogeneities which might affect both labor supply decisions of the elderly and their levels of education and non-labor income, which means, according to some econometric literatures, that the estimated coefficients of the two predictors can be inconsistent. The paper tries to redress the endogeneity problem by employing a panel logit model with data from the 1st. to 4th. wave of the KLoSA(Korean Longitudinal Survey of Ageing) to estimate the effects of key predictors on the probability of getting jobs among older people(ages of 60 or older). Both a random effects and a fixed effects model reaffirms that non-labor income has a negative effect on the chances of being employed. And a random effects model shows that the effect of education is also negative, as has frequently been reported by previous studies. That means the effects of education and non-labor income on elderly employment remain negative after the effect of unobserved heterogeneities is controled for and the problem of endogenous predictors is redressed through an appropriate panel data analysis. These findings mean, in turn, that when Korean baby-boomers, who had acquired an unprecedentedly higher level of education and were expected to enjoy ever-larger amount of non-labor income than their preceding generations, retires in near future, their incentives to work will become much weaker and the lack of labor-force and the burden of financing increased public pension expenditure will become more troublesome. The paper concludes with recommending some policy initiatives helpful to solve these expected problems.

Background: Population aging is a serious problem in Korea. And we have experienced a rapid increase in the health expenditures of the elderly. The purpose of this paper is to analyze the effect of having a usual source of care (USC) for the elderly. Methods: This study used the Korea Health Panel Survey data of 2012, 2013, 2016, 2017, and 2018. The sample was the person who answered the USC questions among the elderly. The panel logit model was used to analyze the determinants of having USC and the panel simultaneous equation model was used to analyze the effect of having USC among the elderly on the medical expenses, medical utilization, and subjective health status. Results: The estimation result shows that age, income, marriage, and so forth turn out to be the factors of having USC. Having the clinic level USC is estimated to reduce the health care utilization and the health expenditure and to improve the subjective health status. Conclusion: It is expected that the result of our analysis will provide evidence for encouraging having USC.

Purpose: This study aimed to identify the factors influencing positive subjective health awareness of middle school-age multicultural adolescents in Korea. Methods: This study used data from the fourth to sixth waves of the Multicultural Adolescents Panel Study conducted by the National Youth Policy Institute. In this study, a panel logit model analysis was performed using the Eviews 8.0 program (p<.050). Results: Socioeconomic status (r=.02, t=2.13, p=.033), body satisfaction (r=.71, t=1.97, p=.048), and depression (r=-.74, t=2.35, p=.018) influenced positive subjective health awareness in multicultural adolescents. When multicultural characteristics were entered into a statistical model with environmental and personal characteristics, multicultural characteristics did not have a significant influence on positive subjective health awareness. Conclusion: Environmental, personal, and multicultural characteristics were related to positive subjective health awareness in multicultural adolescents; thus, an integrated approach considering those variables is recommended. Nursing interventions and educational programs are needed to improve the psychological status of multicultural adolescents and reduce prejudice about them. In addition, nurses need to be sensitive to multicultural characteristics and the developmental characteristics of multicultural adolescents.

Background: Korea shows rapid population aging and increase in healthcare service use and expenditure. Also, this would be accelerated because of the baby boomers who will be 65 years old and more in 2020. Chronic disease is another reason that increases the use of healthcare service and expenditure of the middle- and old-aged households. Catastrophic health expenditure (CHE) is the index which can indicate the households' burden of health spending. Despite the importance, there are few studies on CHE of middle- and old-aged households and especially no panel study yet. This is the reason that this study is carried out. Methods: This study used 3-year data from the Korea Welfare Panel Study conducted from 2009 to 2011. We defined CHE if a household's health expenditure is equal or greater than the threshold value if income remaining after subsistence needs has been met. We used 4 different threshold values which are 10%, 20%, 30%, and 40%. In order to look at the households which experienced CHE, we conducted panel logit analysis after correspondence analysis and conditional transition probability analysis. Results: This study showed three notable results. First, there has been a difference among age groups, which implies that the older people are, the more easily they can experience CHE. Second, the households with no private insurance are shown to have a higher CHE occurrence rate. Lastly, there has been a significant difference among the kinds of chronic diseases. The households which have cancer, cerebrovascular disease, and heart disease have a higher CHE occurrence rate. However, the households with diabetes have no significant effects to CHE occurrence. Also, hypertension has a negative effect to the occurrence. Conclusion: With the results, it can be implied that elderly people with chronic disease are more needed in medical coverage and healthcare. Also, private insurance can play its role in protecting households from CHE. Therefore, it needs to conduct studies on CHE especially about different age groups, private insurance, and chronic disease.
