This study analyzed the factors that affect the use and expenditure of households for childhood education and care centers. The data were drawn from KLIPS(Korea Labor and Income Panel study), vol. 5(2002). From this dataset, 1,171 households were selected for this study. The results of this study were as follows. First, when compared to unemployed mother's households, employed mother's households tended to use childhood education and care centers. Second, with rising household income, the use of childhood education and care centers decreased. Third, the expenditure was much larger for the households with a large income than those with a small income.

This study examined the effects of household head’s worker status change type on household income and household head’s income using a total combined sample of 2,578 households from Korea surveyed in 1998 and 2002 KLIPS(Korean Labor and Income Panel Study). Binary logit regression results showed that household incomes were likely to decrease significantly when household head’s changed worker status from a regular employee, a temporary employee or a daily worker, or an employer or a self-employed to no job status, or from a regular employee to a temporary employee or a daily worker, an employer or a self-employed, or from an employer or a self-employed to a regular employee compared to a regular employee status maintenance. In contrast, household head’s incomes were likely to increase significantly when household head’s changed worker status from a temporary to a regular employee compared to a regular employee status maintenance. Women household heads were significantly associated with the likelihood of the decrease of household head’s income compared to men household heads. Household heads beyond their forties were significantly associated with the likelihood of the decrease of household head’s income compared to household heads in their thirties age-group counterparts. Household heads with education level beyond high school graduation were significantly associated with the likelihood of the increase of household head’s income compared to household heads with the education level of high school graduation. This study shows that a more comprehesive labor policy is needed for achieving sustainable household income inflow.

On the basis of the Korea Labor and Income Panel Survey for the 1997 through 2003 period, this paper investigates if the income distribution has become more bi-polarized since the recent financial crisis. The polarization measure developed by Esteban and Ray(l994) and Duclos, Esteban, and Ray(2004) indicates that the distribution of total income has become much more bi-polarized than unequalized for the entire sample period. Second, the rapid increase in the bi-polarization measure is attributed to the enhanced within-group homogeneity among the lower-income group as well as the widening gap between the two groups in the mean income level. Third, no such pattern exists in the distribution of labor income. Overall, the findings in the current study would support the hypothesis of a centrifuging society which is characterized by the slow disappearance of the middle class and the formation of two poles and which is observed in the United States and the United Kingdom among others.

This paper investigates the wage losses of displaced workers, using data from the Korean Labor & Income Panel Study. Previous Korean studies were only to estimate the wage losses shortly after job displacement. However, if the wage losses persist, those results seem to under-estimate the effects of displacement. Our findings show that the wage reductions are quite persistent 4 years after displacement. And much of this persistence can be explained by the lost labor market experience (lost opportunities to accumulate generalized skills) and additional job losses in the years following an initial displacement.

This study analyzes and verifies the relationship between job satisfaction by factor, organizational commitment, job satisfaction, and overall job satisfaction of working-age workers using a structural equation model. The research data used the 24th data of the Korean Labor and Income Panel Study. The subjects of the study were 8,024 workers in the production age of 15 to 64 as of 2021 among 9,132 people who correctly marked the values of the observation variables. As a result of the study, it was found that job satisfaction by factor had a positive impact on organizational commitment, job satisfaction, and overall work and job satisfaction. In addition, organizational commitment and job satisfaction were found to have a positively significant effect on overall work and job satisfaction. These results emphasize the importance of understanding and solving the unique problems faced by various types of workers in the labor market, ultimately providing important implications for organizations and policy makers to provide workers with an efficient working environment.

The purpose of this study was to find the characteristics of university education expenditure and how university education expenditure affected household finance such as total household expenditure after excluding education expenditure, savings, and debts respectively. The data were drawn from the 8th Korean Labor & Income Panel Study conducted by the Korean Labor Institute, and 563 households with children attending university were selected. The t-test, F-test (Duncan's multiple range test as post hoc test), OLS, and Heckman's two-step estimation were utilized by SAS 9.1 and SPSS 12.0 for Windows. The results were as follows: First, average annual tuition was found to be 6,170,000won(21.5% of total annual household expenditures) and average annual private education expenses were 4,920,000won(15.9% of total annual household expenditures). Second, the higher the household income levels, the more spent on university education, whereas the higher the household income level, the lower the household expenditure-to-university education ratio. Third, tuition and private education expenses had a negative impact on household expenditures after excluding education expenditure.

The goal of this study is to analyze one-child households' financial structure. The data from 1022 more than two children households and 236 one-child households were taken from the Korean Labor and Income Panel Study(2004). This study compared demographic, socioeconomic and marital characteristics between one-child households and more than two children households. A chi-square test, t-test and multiple regression analysis were used. The major findings were as follows: One-child households were different from more than two children households in demographic socioeconomic characteristics and financial structure. In one-child households, the variable that significantly influenced on consumption expenditures was monthly income and the variables that significantly influenced on private education expenditures were householder's age, home-ownership, monthly income.

Purpose: The purpose of this study is to estimate incomes and costs of the medical clinics by using secondary data. Methodology: The medical incomes and costs were estimated from 405 clinics operated by sole practitioner providing out-patient services among all clinics subject to the Medical Cost Survey on National Health Insurance Patients in 2017, excluding dental clinics and oriental medical clinics. The incomes and costs of the medical clinics were reflected with incomes and costs of health insurance benefits and were calculated by types of medical services (i.e., basic care, surgery, general treatment, functional test, specimen test and imaging test). The costs were classified as follows: labor costs, equipment costs, material costs and overhead costs. Secondary data was used to estimate the incomes and costs of the medical clinics. For allocation bases for costs for each type of the medical service, the ratio of revenue from health insurance benefits by types of medical services was applied. However, labor costs were calculated with the activity ratio by types of medical services and occupations, using clinical expert panel data. Finding: The percentage of health insurance income for all medical income was 73.1%. The health insurance cost per clinic was 401,864 thousand won. Labor cost accounted for the largest portion of the health insurance income was 191,229 thousand won (47.6%), followed by management cost was 170,018 thousand won (42.3%), materials cost was 35,434 thousand won (8.8%), and equipment costs was 5,183 thousand won (1.3%). Practical Implications: This study suggests a method of estimating incomes and costs of medical clinic services by using secondary data. It could efficiently provide incomes and costs to assess an appropriate level of the health insurance fee to the clinics.

The purpose of this study was to find how financial structures differ from the family life cycle. The data was drawn from the 2002 Korean Labor and Income Panel Study conducted by the Korea Labor Institute, and 1,957 households. The level of total income and subcategories of income were found to be significantly different from the family life cycle and showed tendencies to increase up to the period of child birth and then sharply dropped down during the retirement period. Household consumption expenditures in total and subcategories showed a U shape by family life cycle and were also found to be significantly different from the family life cycle. The consumption expenditure of dining out showed the highest level at the beginning of family establishment, whereas medical cost showed the highest level for later years. The level of total assets increased gradually from the family life cycle and a little decreased for the later years, and the level of real estate assets showed the highest ratio(90% over) out of total asset components of family life cycle.

The aim of this study was to examine whether health status is different according to employment status and income level in wage-earners. We analyzed wage-earners of 2199 men and 1194 women aged 30-64 years, using data from the 2006 Korean Labor and Income Panel Study(KLIPS). The difference of health status according to employment status and income level was compared with the multiple logistic regression and the standardized concentration index of ill-health. The risk of ill-health was high when waged-earners had low income. The same is true for poor employment status when their employment status was unstable as in manual laborers, irregular workers, temporary, daily workers or part-time workers. furthermore, the wage-earners with lower income and a relatively disadvantageous employment status showed the lowest health status compared to other groups. Ill-health was relatively more concentrated in lower income group and poor employment status. This study identified the existence of health inequality among various employment status of wage-earners. It is suggested that policies that deal with the inequality in social class may have an important impact on the health of the population.
