인구고령화의 진전과 함께 노인들의 거주형태에 대한 사회적. 정책적 관심이 증기하고 있으며, 그에 대한 논의와 연구들 또한 많이 늘어나고 있다. 그러나 이들 연구 대부분이 횡단적 자료(단일 시점이든 여러 시점이든)와 분석에 의존함으로써 노인지 거주형태가 생애주기를 따라 변하는 모습을 충분히 보여주지 못하고 있다. 이 연구는 한국노동연구원의 제1차 및 제6차 노동패널자료를 이용해 노년기 거주형태의 유동성을 경험적으로 제시하려는 목적을 가진다. 이들 위해 거주형태의 출현율(prevalence rate)과 전이율(transition rate)을 개념적으로 구분하고 자녀동거여부에 대한 분석을 실시하였다. 두 시점에 대한 횡단폭 분석결과는 노인들의 사회인구학적 특성에 따른 자녀별거경향의 차이를 보여주더라도 생애주기에 따른 역동성을 보여주기에는 한계가 많음이 확인되었다. 두 시점 간의 거주형태 변화에 대한 패널분석에서는 다수 노인들의 거주형태가 주어진 기간 동안 안정적으로 나타났다. 그러나 거주형태의 변화를 경험하는 데에는 연령증가와 배우자 상태변화 등이 중요한 요인임이 확인되었다. 이러한 생애주기적 변화의 효과는 대부분의 계량적 연구에서 유추되는 수준이거나 질적 연구에서만 보고되어 왔던 것이다. 이 연구결과는 노년기 거주형태의 지속성을 보여주는 한편 변화 가능성과 요인을 파악함으로써 노년기 거주형태에 대한 개념적 이해론 공고히 할 것으로 기대된다. 또한 이 연구에서 제시된 방법론적 논의와 접근방식은 생애주기별 변화에 초점을 두고자 하는 다른 연구영역에서도 적용 가능할 것이라 기대된다.

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.

The purpose of this study is to investigate what factors affect cyber-delinquency after examining the previous research focusing on the general strain theory and the delinquency opportunity theory in the existing studies. And as adolescents move from middle school to high school, this study is intended to analyze what factors affect cyber-delinquency from a longitudinal perspective using KCYPS(Korea Child and Youth Panel Survey) elementary 4th grade fourth and seventh data. The adolescence cyber-delinquency probability of occurrence were analyzed through the panel logit fixed-effect model using STATA. And then the cyber-delinquency frequency of adolescents were analyzed through the panel tobit random-effect model. As a result of analyzing the factors affecting cyber-delinquency frequency, Adult media commitment, computer use time, and cell phone dependency increased cyber-delinquency frequency. On the other hand, among the parenting attitudes, the attitude of supervising attentively and adolescents' age-increasing decreased cyber-delinquency frequency.

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.

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 explores whether or not a minimum wage increase can do much to alleviate working poor. For this purpose, I analyze transitions from working poor to working non-poor and to unemployment or non-economically active states, using KLIPS (Korea Labor and Income Panel Study). This study uses the multilevel multinomial logit model to control unobserved individual heterogenous characteristics. It finds that a minimum wage increase tends to cause a higher probability of transitions from working poor to working non-poor. It is also discovered that a minimum wage increase is not negatively related with the persistence of the working state. It is concluded that minimum wage increases are likely to be effective in improving the living standards of the 'working poor'.

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.

This study intends to the estimate the determinants and state dependence of long-term care services in Korea. For this purpose, we analyzed the transition patterns among three states of long-term care service utilization over time by using the Korea Welfare Panel Study data with the random effect multinomial logit model. It is found that the result showed a strong state dependence in long-term care service utilization. Especially, long-term care insurance for the elderly showed a strong state dependence among others. Among the individual demographic characteristics, the higher the age, the higher the probability of using long-term care insurance for the elderly, while the lower the probability when married. The characteristics of the residential region showed that the residents of the urban-rural integrated region had a significantly higher probability of using long-term care insurance than the reference region. The results of this study suggest that the long-term care service users have a strong state dependence, which means that it is important to take into account the increase in the utilization period of existing users in future demand forecasting.

This study compared and analyzed the effect of the burden of household expenditure in the metropolitan and non-metropolitan areas on the intention to childbirth intention to married women using a panel logit model. To this end, this analysis targeted married women aged 25 to 39 who are highly likely to be fertile. The main results are as follows; First of all, it was confirmed that the economic power of spouse can be an important factor in the childbirth intention regardless of region. Second, it was found that the higher the satisfaction of marriage had a positive effect on the childbirth intention, and also higher the value that children must have, the higher the childbirth intention. Third, it was confirmed that the burden of household expenditure is the most important factor in the willingness to childbirth intention, excluding factors such as the number of existing children. In particular, the burden on education spending in both the capital region and non-capital region was found to be a key reason for the decrease in the childbirth intention. Lastly, the burden of household expenditure showed different effects on childbirth intention on depending on the region. Specifically, in the capital region, medical spending and loans had a greater impact, while, in the non-capital region, transportation and communication costs had a greater impact on childbirth intentions. Through the results, this study confirmed the implication that easing the burden on household expenditure is continuously necessary to enhance childbirth, and that discriminatory policy approaches are required depending on the area of residence.

This choice experiments study values the non-market benefits of water quality improvements in Paldang Reservoir and Han River, located in Korea. A fractional factorial orthogonal design was used to produce four different choice sets per respondent, before employing choice examples to screen out irrational responses. The panel mixed logit model (with normal distributions for the attributes) fit the data best, indicating that allowing for both heterogeneous preferences across households and correlation between repeated choices may represent actual choice behaviors best of all the estimated models. The significant standard deviations of the random attributes suggest that the taste for each attribute may vary considerably in the population. The annual benefits to the Seoul Metropolitan area for a small (large) enhancement of the clarity of water, a gradual removal of unpleasant waters, and a gradual improvement in biodiversity, were estimated to be some 1.5 trillion (1.7 trillion) Won, 2 trillion Won, and 1.7 trillion Won, respectively, with 1.8~2.6 trillion Won for at least two of them occurring together. The study also discusses potential biases germane to choice experiments studies of this type.
