  • Until recently, self-employment workers are often excluded from labor market studies. Most relevant studies has focused on the determinants of entry into self-employment. However, the self-employment is highly exposed to poverty risk although they are working. Despite that, relatively little is known about the economic severity of the self-employed. This study uses data from the Korea Welfare Panel Study to examine the situation of the self-employed's in-work poverty and the determinants of in-work poverty among them. Major findings are as follows. First, self-employed people experience 3.5 times higher in-work poverty risk than employees. Especially, the ratio of own-account self-employed people living below the poverty line is similar with that of even precarious employees. Second, the extent of poverty of self-employment is more serious. Third, the proportion of self-employed among working poor is about 53% although self-employed workers are composed of only about 24% among working people. Fourth, temporary employees and self-employed people are more likely to be poor than full time employees according to logistic regression. It is statistically significant. It implies that it is desirable to regard the self-employed as the policy target group along with temporary employees. Fifth, the ratio of in-work poverty of self-employed aged 40-64 whose education level is low and the self-employed aged 40-64 who work in low-skilled service sector are higher than that of the other group. It implies that measures to alleviate their economic difficulties are urgently needed.

  • Objectives: This study compared the welfare level and leisure activities of children and the youth in urban areas with rural areas, and examined factors affecting their life satisfaction. Methods: The fourth wave of the Youth Panel data collected by the Korea Youth Policy Institute has been utilized. A total of 3,145 sample was drawn, and the average age of the sample was about 17 years old (a sophomore in high-school). T-test and multiple regression has been employed. Results: In almost all welfare related variables including life satisfaction, leisure satisfaction, parent attachment, and relationship with teachers and peers, the rural children and youth showed lower scores than their urban counterparts. The only factor whose score was higher to the rural children and youth was community factor including community attachment and guidance. In terms of leisure (satisfaction) level which was the most influential factor of predicting the variance of life satisfaction, the rural children and youth revealed unfavorable condition, as their accessibility to the facilities was low and there were less facilities in rural areas in the first place. Conclusions: As a way to improve the welfare and cultural level of rural children and youth, this study proposed to make investment to the rural areas by providing them with welfare and leisure infra structure and various welfare and leisure programs.

  • This study analyzed the change of after-school guardians' absence types during the first 3 school years, and the relations of after-school care, family environment(family income, parental monitoring) to self-regulatory learning ability and emotional-behavioral problems in each gender of early school-age children from dual income families. The data from 526 boys and 483 girls among 3rd graders of Korean Child and Youth Panel Survey(KCYPS) were statistically analyzed by Friedman's test, t-test, correlational coefficient analysis, regression analysis. The results showed that 45% of boys and 50% of girls were with a guardian for their after-school care in each of the first 3 school years and after-school care had changed gradually into the types of temporal or contingent absence of a guardian. Family income and children's self-regulatory learning ability were different from adult-care and self-care in each gender, but there were differences in the parental monitoring of girls and emotional-behavioral problems of boys according to the care types. Both of boys and girls showed that family environment meaningfully related with the ability and the problems, and also showed the relatively different effects of after-school care and family environment on those ability and problems variables. The results suggested some implications for after-school care.

  • The objective of this study is to describe and determine how and to what extent size of firm, operating vessels and interest cost, leverage, debit maturity, growth opportunity and cash flow affect the cash holdings of Korean shipping companies. A sample of 38 Korean shipping firms for a period of 9 years(from 2005 to 2013) was selected. In panel data regression, this study finds that cash holdings are negatively affected by firm size, operating vessel size and debit maturity, and positively affected by volume of interest costs. In firm's group of relatively large volume of operating vessel, it's cash holdings are affected by debit maturity, cash flows and growth opportunity but in firm's group of small volume of it, interest cost, debit maturity and operating vessel's size are related with cash holdings. It proved that determinants of cash holdings in a high interest costing group are size of operating vessel, interest cost and debt maturity. On the other hand, debit maturity, growth opportunity, firm size and extent volume of vessels are associated with cash holdings in relatively row interest costing group.

  • This study examined one of the contemporary issues on debate to identify any significant financial determinants on the cash holdings of the cheabol firms in the Korean domestic capital markets. Several important findings on the financial characteristics affecting the cash holdings were evidenced by utilizing various methodologies for statistical estimations. Financial or managerial implications with discussion were provided for the pronounced factors such as CASHFLOW, MVBV, REINVEST, and AGENCY. Assuming that the chaebol firms were overall subject to the financial constrains, they may increase or stockpile cash reserves as internal capital for future investment opportunities or repayment of existing debt, rather than external financing burdened by a high cost of capital. Given the on-going controversy on the optimal level of corporate cash holdings coupled with any foreseeable capital transfer among the associated nations through the investment vehicles such the FTAs (Free Trade Agreements) or TPP (Trans-Pacific Pacts), any empirical findings of the study may shed new light on identifying financial determinants which may significantly affect the level of cash holdings for the business conglomerates, the 'chaebol' firms, in the Korean capital markets.

  • The purpose of this study is to examine the effects of household income types and sources on the depressions and self-respect of the old aged. Although household income types and sources are supposed to be important to the mental health of the old aged as well as income level, there have been little policy interests to them. This study analyze the relationship between the household income types & sources and the mental health of the old aged, using the 8th data from the Korean Welfare Panel Study. Major findings are as follows. First, we find that there are considerable variations in the household income sources composition among the old aged, and that types of household income are related to the individual and family features of the old aged. Second, the results of regression analyses show that the household income types are associated with the depression and self-respect of the old aged. And, we find that some income sources affects the mental health of the old aged. The results of this study suggest that there should be policy attentions to the mental health effects of the household income sources so as to increase the adequacy of the income security system for the aged in Korea.

  • Using the Korean Survey of Household Finances and Living Conditions panel data from 2012~2016, this study analyzed youth (19~34 years) poverty and employment and examined the factors that affect employment status. The analysis revealed an increase in the proportion of young people who are students or jobless; the economic conditions of the young people varied by factors such as marital status, education, job status, and loans; and the government public transfer policy had little impact on reducing the relative poverty rate of the youth. We also examined the factors affecting the youth's employment status and the risk of being employed in low-paid jobs, using multi-logit and logit regression model respectively. Considering employment status, the older and more educated the youth were, the less frequently they were employed in temporary or daily jobs instead of regular ones, but there was no difference between genders in terms of having temporary or daily jobs. A logit analysis on the determinants of low-paid jobs demonstrated that women, the less educated, spouses or children of the household, and temporary or daily workers have a greater probability of working at low-paid jobs. As women became older, their risk of having low-paid jobs increased, which demonstrated the phenomenon of "lock-in" at low-paid jobs. Temporary or daily workers of all age groups faced a higher risk of lowpaid employment, which stood out for the youth. Based on these results, we suggest that government employment and welfare policies should consider individual characteristics of the youth and their life cycle, along with efforts to supply decent jobs, continuously and stably.
