This study examines the relationship between intergenerational financial resource transfers and preparation for later life among the middle-aged. The study sample consists of 1536 middle-aged individuals with at least one living parent and one married child. The level of preparation for later life is dependent upon the level of household economic status. The statistically significant variables predicting the level of preparation for later life include age, education, subjective health status, household income and household assets. Moreover, intergenerational resource transfers are statistically significant factors that explain the level of preparation for later life. The effect of financial transfers from middle-aged parents to their adult children on the level of preparation for later life is the most significant financial transfer variable.

This study examines the condition of transfers between mothers and adult children, analyzing the influencing factors in such transfers. Specifically the study examines the influence of financial transfers and economic resources on financial transfers and grandchild caregiving between mothers and adult children. The sample of 3719 mothers with adult children was extracted from the first wave of the Korean Longitudinal Survey of Women and Families. The major findings are as follows. Mothers's socio-demographic characteristics are important factors in explaining financial transfers between mothers and adult children. Mothers who have jobs and spouses are more likely to provide economic resource to their adult children than those who don't have. In terms of receiving economic resources from adult children, statistically meaningful factors are mothers' age, labor market participation, marital status, household income, household asset, and children's labor market participation. Especially, labor market participation of mothers and adult children is statistically powerful factor in financial transfers and caregiving.

We examined if intergenerational proximity might be associated with upstream financial transfer from adult children to older parents, and whether adult child gender might moderate the association. We considered siblings' proximity to parents, as well as that of the adult child. Prior work conducted in the US and other countries has suggested that children living further from parents might provide financial support to compensate for instrumental support provided more by siblings living closer to parents. Data were drawn from the Korean Longitudinal Study of Ageing (2014). Our analytic sample consisted of older adults 60+ and their children aged 35 and 55. None of the children co-resided with parents. Parental households consisted of either widowed individuals or married couples. For within-family analyses, fixed effects and random effects regression models were estimated. Results suggest first, sons living within a 30-minute distance, or within an hour to two-hour distance provided more monetary support to married parents compared to daughters. Second, contrary to existing findings, greater financial assistance was provided by sons and daughters when no children lived within an hour distance from their parents. For widowed parents living alone, intergenerational proximity was not associated with the amount of financial transfer from adult children.

The purpose of this study is to analyze the influences on resource transfers between middle-aged parents and their married children. This study used 2009 data from the National Research Foundation of Korea regarding inter-generational resource transfers and preparation for later life (kfr-2009-c00010). A sample of 1208 households of middle-aged parents with married children was used. The study found that parents provided financial resource transfers to their married children in the following circumstances: where parents received financial resource transfers from their married children, where the household income of parents was high, where the children were younger, and where the children were male. Parents provided instrumental resource transfers to their married children in the following circumstances: where parents received instrumental resource transfers from their married children, where the gender of children was female, where the children were employed, where married children had their own children who were either younger than a preschooler, and where household incomes of married children were high. Parents received financial resource transfers from their married children in these circumstances: where their emotional ties with their children was high, where the household income of the parents was low, where the household income of the married children was high, and where married children had preschoolers. The circumstances in which parents received instrumental resource transfers from their married children were where parents provided instrumental resource transfers and the household incomes of married children were high.

The purpose of this study is to analyze the influence of parent-to-child financial transfers, providing household chores, and inheritance on financial transfers and time transfers from adult children to their elderly parents with dementia. Analyzing data from the sample of 343 adult children of parents with dementia, this study finds a strong positive effect of prior parent-to-child financial transfers on child-to-parent financial transfers under controlling parent characteristics, respondent characteristics and sibling's transfers to their parents. The effects of providing household chores and inheritance on time transfers are also positively significant. The results of this study point out the importance of reciprocity in resource transfers between adult children and their parents with dementia.

This study examines whether reciprocity exists in intergenerational resource transfers from middle-aged children to elderly parents. Analyzing data from a sample of 1123 middle-aged adults, this study highlights the importance of reciprocity in the transfer of resources between middle-aged adults and their elderly parents. The possibility of an inheritance shows a very strong effect on care-giving to elderly parents. Furthermore, past financial transfers from parents to middle-aged children correlates strongly with financial transfers from middle-aged children to their elderly parents.

최근 각국은 자국의 해양자원을 보존한다는 명분으로 EEZ선포를 서두르고 있다. 한반도 주변과 같이 서로 인접한 수역에서의 EEZ설정은 필연적으로 각국의 이해관계가 상충될 수밖에 없고 따라서 이의 해결을 위해 인접국들은 합의에 의해 공동어로수역을 설정하고 이를 공동을 관할하려 할 것이다. 이 논문은 각국이 공동어로 수역을 설정하여 접속수역에 대해 인접국에게 관할권을 부여할 경우 초래될 수 있는 점을 게임이론과 정치경제적인 접근으로 이러한 문제를 다루었다. 즉, 접속수역에서 인접국은 자원의 채취에 있어서 다국과의 차별적인 규제를 시행하고 타국도 마찬가지의 정책을 구사할 경우 도덕적 위해(moral hazard)에 의해 각국의 접속수역에서의 자원이 가속적으로 고갈될 수 있다는 점을 보이고 있다. 또한 단기적인 전략적 산업정책의 수행은 타국의 희생하에 시장점유율을 확대시키며 그 결과 이윤의 이전을 가져오며 이는 자국 후생의 향상을 가져올 수 있다는 브랜드-스펜서(Brander-Spencer)의 결과는 수산자원과 같은 갱생지원의 경우에는 적용될 수 없다는 점을 보이고 있다.

본 논문은 심각한 환경오염에 직면한 북한 환경오염에 관한 현황을 분석하고 향후의 환경오염 발생량을 추정하였다. 그러나 제한적인 북한의 에너지, 환경 및 경제관련 자료를 이용하여 에너지 수요 및 환경오염을 예측하였음으로 모형에 사용되는 계수의 설정과 추정결과의 어려움은 있음으로 향후 계속해서 보완해야 할 것이다. 구소련권과 통일 독일의 경우에서 보듯이 환경파괴에 의한 복구비용이 엄청난 경제적 비용을 초래하고 있다는 점을 고려할 때, 지금까지 제한되어 왔던 북한의 환경에 관한 연구를 본격적으로 시작하여 남 북한 환경협력방안을 수립하는 것이 바람직하며 환경기술의 이전을 통한 환경산업의 활성화도 남북 경협의 차원에서 고려해 볼만하다고 본다.

This study aimed to examine the relationship between the expectation of independent life in old age and intergenerational downward transfer of Korean old people. It was focused on old people who did not live with their adult children by using the raw data of "2008 the Korean study of Welfare Services for the Elderly". The data were analysed by multiple regression analysis. The results showed the degree of the expectation of independent life in old age had positive effect on economic and service downward transfer of old people. Concretely, the degree of the expectation of economic and physical independence had positive effect on economic and service downward transfer of old people. The degree of the expectation of emotional independence had positive effect on service downward transfer of old people, while it had no effect on economic downward transfer.

Variable renewable energy (VRE) such as solar and wind power is the main sources of achieving carbon net zero, but it undermines the stability of power supply due to high variability and uncertainty. Energy storage system (ESS) can not only reduce the curtailment of VRE by load shifting but also contribute to stable power system operation by providing ancillary services. This study analyzes how the allocation of ESS resources between load shifting and ancillary service can contribute to maximizing the efficiency of power supply in a situation where the problems caused by VRE are becoming more and more serious. A stochastic power system optimization model that can realistically simulate the variability and uncertainty of VRE was applied. The analysis time point was set to 2023 and 2036, and the optimal resource allocation strategy and benefits of ESS by varying VRE penetration levels were analyzed. The analysis results can be largely summarized into the following three. First, ESS provides excellent functions for both load shifting and ancillary service, and it was confirmed that the higher the reserve price, the more limited the load shifting and focused on providing reserve. Second, the curtailment of VRE can be a effective substitute for the required reserve, and the higher the reserve price level, the higher the curtailment of VRE and the lower the required amount of reserve. Third, if a reasonable reserve offer price reflecting the opportunity cost is applied, ESS can secure economic feasibility in the near future, and the higher the proportion of VRE, the greater the economic feasibility of ESS. This study suggests that cost-effective low-carbon transition in the power system is possible when the price signal is correctly designed so that power supply resources can be efficiently utilized.
