  • This study used data from the 6rd and 12th year of the Korean Welfare Panel to evaluate the effects of the Personal Assistance Service(PAS) system on the labor market of PAS users' participation. For the purpose of this study, 64 program groups using the Korean PAS and 344 control groups not using the Korean PAS were selected using Caliper matching among the propensity score matching. A chi-square test was used for the difference in characteristics between groups, and a simple difference-in-differences (DID) model and a double-difference multiple regression analysis of DID were performed to estimate the effect of thepolicy before and after the Korean PAS. As a result of the study, it was found that statistically, PAS had no significant effect on the labor market. This is due to the low number of system users, resulting in low post-hoc power, incomplete matching and limited availability of PAS Assistants for Disabled People. Therefore, In order to demonstrate the effectiveness of the Personal Assistance Service(PAS) system, specialized services and systems that meet the needs of the disabled and household members should be implemented.

  • The purpose of this study was (a) to identify latent profiles among employed Korean mothers of third graders based on work-family conflict, work-family enrichment, work-parenting conflict, and work-parenting enrichment, (b) to examine the antecedents of profile membership at the individual, family, work, and community levels, and (c) to investigate the differences in the various psychological outcomes across the profiles. The sample of 451 married employed mothers was a subset of data from the 10th Wave of the Panel Study of Korean Children, which was collected in 2017 when the focal child was in the third grade. Our latent profile analysis suggested a three-profile model that comprised enriched (11.91%), moderate (47.85%), and mixed (40.24%) profiles. The significant antecedents of profile membership were subjective health status, the child's adjustment to school, working hours, the community's suitability for childrearing, and satisfaction with community service facilities. Regarding psychological outcomes, the levels of life satisfaction, marital satisfaction, and job satisfaction were higher in the following order: enriched, moderate, and mixed profiles. The levels of depressive symptoms were in the reverse order: mixed, moderate, and enriched profiles. This study contributes to a comprehensive understanding of the literature on work-family interactions by considering various predictors and outcomes at multiple levels.

  • This study examined the relationship between physical education and externalizing(aggression) and internalizing(depression, social withdrawal) problem behaviors among adolescents. The moderating role of gender and time in the association between physical education and problem behavior was also identified. This study used data from the second, third, and fourth waves of the middle school student cohort (N=2,133, N=2,151, N=1,979) of the Korean Children-Youth Panel Survey(KCYPS). Main analyses involved multilevel growth model with interaction terms. The dependent variables were aggression, depression, and social withdrawal. The independent variables were gender and physical education (exercise hours) at school. The control variables were abuse, school-adjustment, annual household income and parents' highest level of education. The major longitudinal findings of this study are as follows: First, there was significant change according to the passage of time only in aggression among externalizing and internalizing problems. Second, gender differences exist in aggression and depression. Third, exercise hours of physical education had a negative relationship with internalizing problems. Fourth, there were no gender differences over time in both externalizing and internalizing problems. Fifth, the interaction between exercise hours of physical education and time was statistically significant for social withdrawal. Sixth, the interaction between exercise hours of physical education and gender was statistically significant for depression. The results of this study may become an academic basis for suggesting policy directions that promote increased exercise hours in physical education classes at school.

  • This research multilaterally analyzed the frequency of use of OTT service and its effect on life satisfaction for office workers of the MZ generation using the survey data of the Korean Media Panel. Recently, the OTT service market has grown rapidly, but there is a lack of research on what changes these changes have brought to the lives of the MZ generation. In this research, the frequency of OTT service use was investigated according to the characteristics of workers in the MZ generation, and a research model was set up to test whether the frequency of use affects life satisfaction. In fact, the frequency of use varied according to the gender and age group of the MZ generation, and it was found that the frequency of use also affected life satisfaction. It has an academic contribution in that it was the first to study the relationship between media content use patterns and life satisfaction. In the future, additional research is possible not only on the frequency of use, but also on the type of OTT content and the time of use of OTT service.

  • Foreign direct investment is the means for companies to enter the overseas market and strengthen their competitiveness. The holding of intellectual properties, representing advantages of firms, may affect foreign direct investment. By expanding previous studies, we define intellectual properties as including trademarks and design as well as patents. Using a random-effect panel data model, we examine the effects of both intellectual properties of Korea and host countries on Korea's foreign direct investment in 128 countries from 1981 to 2014. The results are as follow. First, the coefficients of Korea's intellectual properties, patent, trademark, and design are significantly positive. This implies that Korean firms may invest abroad to take their advantages of technologies, brand value, and the capability of product differentiation. Second, except for patents, intellectual properties of host countries have a positive impact on foreign direct investment. In other words, foreign direct investment to acquire the ability of branding or product design from host countries may occur. Third, the coefficients of Korea's intellectual properties are significantly greater than those of host countries' properties. Foreign direct investment to take advantages of the firms' capabilities overseas is greater than one to acquire knowledge of host countries. Finally, Korea's intellectual properties have a greater positive impact on foreign direct investment in high growth countries than in low growth countries. It is interpreted that Korean firms are more motivated to exploit their intellectual properties in developing countries with a high growth than developed countries. Overall, it is confirmed that Korea's foreign direct investment not only to utilize some advantages but also to seek the brand value or product differentiation ability from host countries can occur. Our findings provide the contribution that some innovative activities in firms and R&D investments policies which encourage the possession of intellectual properties can improve foreign direct investment.

  • The purposes of this study were to investigate the transition of elderly's welfare service utilization and to examine the factors affecting their utilization as time passed. To solve these research questions, the behavioral model presented by Andersen and Newman(1973) was applied. Using Hallym Aging Panel data consisted of 3 waves from 2003 to 2007, autoregressive modeling and regression analysis were applied for research purposes. The results of this study were as follows; (1) The experiences of welfare service utilization were increasing gradually. The complimentary service for the aged was utilized generally, but leisure service and community service were not used in common. (2) Past experience of service affected service utilization in the following times. (3) The factors affecting older adult's service utilization were different among the types of services. Nonetheless, the factors affecting continuously during the periods were found: age as predisposing factor and area as enabling factor in the complimentary service; area and existence of spouse as enabling factor in leisure service; education as predisposing factor and service cognition as enabling factor in community service. Enabling factor has affected more consistently than other factors. The results showed that special attention should be paid to balanced regional arrangement for welfare resources and the public relation considering the elderly's intellectual level.

  • This study advances the knowledge of developmental patterns in affiliation with delinquent peers and delinquency during adolescence; data were obtained from waves 1-5 (2003-2007) of the Korea Youth Panel Survey. Semi-parametric group-based modeling (SGM) identified 3 affiliative trajectories of delinquent peers from age 13 to 16: rarely or never, persistently affiliative, and declining groups; and five developmental trajectories of delinquency: non-offending, late onset, low-level continuous, desisting, and chronic groups. A joint trajectory analysis predicted the membership of delinquency trajectories conditional on delinquent peer trajectories. Persistently affiliative group was more likely than others to follow chronic trajectory of delinquency; the rarely or never affiliative group was more likely to be non-offending. This study may help reconcile different theoretical models such as influence, selection, and enhancement models with respect to the role of delinquent peers in delinquency. The distinct theoretical models are equally valid, albeit each model pertains to a specific aspect of longitudinal patterns of affiliation with delinquent peers. Implications of this study for youth welfare were discussed to reduce increased risks for both affiliation with delinquent peers and delinquency.

  • The powerful association between poverty and mental health has been recognized for many decades in the Western Countries. Despite growing poverty studies, there has been little attention to the association between poverty and mental health in Korea. In this article we examine the effects of the mental health on the poverty status transition. In this study we draw on nationally representative data from the The Korean Welfare Panel Study, to estimate the effects of depression and self-respects on the poverty status transition. Major findings are as follows. First, we find that there are mental health disparities between poor and non-poor classes. The mental health conditions of the poor are worse than the non-poor. Second, we find the strong correlations between the mental health and poverty status transition. Whether poor family exits poverty or not depends on the household head's mental health. Third, poverty experiences are different depending on the mental health conditions. To the mental ill-health family, the probabilities of poverty-exit are much lower and poverty duration is more long. Fourth, we find that family poverty status transitions are very significantly related with household head's mental health from the logistic model analysis. These findings suggest that there is a strong relationship between poor mental health and the experience of poverty in Korea. They also suggest that intervention programs to enhance the mental health of the poor are needed in order to reduce the poverty problem in Korea.

  • Most of the research regarding economic effects of policy loans has thus far been focused on whether policy loans can improve the financial status or the management performance of small and medium enterprises (SMEs). Unlike previous researches, this study implemented an empirical analysis focused on the contribution of policy loans to easing the liquidity restriction of investment. To analyze whether investment liquidity restriction can be alleviated or not, this study attempted an empirical analysis utilizing the nonlinear Euler equation induced through optimization of investment and GMM (generalized method of moments) as its analysis methodology. With the SMEs that received policy financing from the Small and medium Business Corporation (SBC) in 2004, this study analyzed three years of panel data before(2001~2003) and after(2004~2006) receipt of policy loans. According to the empirical results, it appears that policy loans had effects on resolving liquidity restriction of investment, implying that policy financing eases the liquidity restriction of SME investment and would contribute to the growth and development of SMEs. Further, I checked robustness of empirical results using Tobin's q model. The empirical results also support that policy loans help to resolve liquidity constraint. With these results, it is understood that the critical view to date, which has emphasized the ineffectiveness of policy financing due to it having no or insignificant economic effects, may be wrong.

  • Initially entering into the job market during hard times with unfavorable market institutions has a persistent, negative effect on young workers' subsequent employment. This paper analyzes hysteresis in youth unemployment by using a composite fixed-effect panel data model. Data sets for the age-cohort unemployment rate and for labor market institutions are constructed from OECD statistics from 21 advanced economies, including Korea, from 1985 to 2017, and are then readjusted to match with the peculiarities of the Korean market. In Korea, with a less-aggressive stance on active labor market policy spending, a male worker who experiences a one percentage point higher youth unemployment rate when he was 20- to 29-years-old has a 0.146 percentage point higher unemployment rate at the ages of 30-to 34-years-old and a 0.035 percentage point higher unemployment rate at the age of 35- to 39-years-old. These figures are larger than those in most countries that have more aggressive spending schemes. These findings point out that hysteresis in the Korean labor market can be mitigated by expanding active labor market policy spending more aggressively and more effectively.
