The purpose of this study was to investigate the economic effects of a flame retardant aluminum screen developed by a company Economic effects were analyzed in terms of micro and macro-economic aspects. In the macro-economic aspect, economic effects were analyzed under the assumptions that the total import volume of flame retardant aluminum screen was approximately $50m^2$ in 2015 and that possible import substitution rates were 100%, 80%, and 60%. Results showed economic values of 2.25 billion won (100% import substitution rates), 1.8 billion won (80% import substitution rates), and 1.35 billion won (60% import substitution rates). If existing farms which had been using imported flame retardant aluminum screen replaced it newly developed with the flame-retardant aluminum screen developed in this study at rates of 100%, 80%, and 60%, the farms could save 750 million won, 60 million won, and 45 million won, respectively. Furthermore, the social cost savings from fire prevention could be 1.184 billion won. In the micro-economic aspect, if a farm with a typical-size ($1,000m^2$) greenhouse growing red pepper wanted to install flame retardant aluminum screen instead of generic aluminum screen, the farm may only pay an additional cost of 720,000 won. In comparison, if the farm chose fire insurance instead of flame-retardant aluminum screen, then the farm would pay 21,000,000 won for fire insurance. The above results show that the economic effect of flame retardant aluminum screen developed by the company would be be very efficient compared to the imported one.

Purpose - Since China has been South Korea's biggest export destination, uncertainty shocks originating from it would influence South Korea's exports. This paper evaluates the effects of China's economic policy uncertainty on Korea's exports to explore the transmission channels. Design/methodology - Incorporating endogeneities and nonlinearities, this study employs a quarterly time-varying parameters vector autoregressive model to investigate the relationships between China's economic policy uncertainty and Korea's exports, where the overparameterization due to time-varying specifications is overcome by a novel stochastic model specification search framework. According to previous theoretical studies, this paper assesses two channels, demand shock channel and exchange rate channel, through which foreign uncertainty affects Korea's exports. This paper identifies the primary drivers of Korea's aggregate exports and analyzes the rationales for the time-variant impacts of China's economic policy uncertainty on Korea's exports to China. Findings - Our empirical results reveal that Korea's aggregate exports are less responsive to China's economic policy uncertainty shocks and significantly move together with global demand. In contrast, its bilateral exports to China are highly responsive in a negative and time-variant way. Moreover, Chinese investment is an important channel through which China's economic policy uncertainty affects Korea's exports to China after 2010. Further, the time-variant effects of China's economic policy uncertainty on Korea's exports to China are related to changes in China's foreign trade policies, global economic conditions, and China's degree of economic freedom. Originality/value - Few previous studies touch the effects of external uncertainty shocks on South Korea's exports. This paper attempts to fill this gap and explicitly investigate the impacts of China's economic policy uncertainty on Korea's exports from a time-varying perspective. As Korea is an export-oriented economy, this study provides insights for the Korean government to understand the transmissions of external uncertainty better.

The private sector is currently reviewing the feasibility of the project or deciding economic policies by analyzing the economic ripple effects. However, the arms acquisition project focuses on the need for the national defense weapons system by analyzing the costs and the effectiveness of the analysis and reviewing the necessity and feasibility of the project. In order to analyze the economic ripple effects, KB (the Bank of Korea) prepares and publishes an analysis table of industrial associations in a given unit. IAAR (the industrial association analysis report) is difficult to apply directly to the defense weapons system. Therefore, research on the economic ripple effects applicable to the defense arms procurement project was needed. In this study, we propose the generic methodology for estimating economical and technical ripple effects resulted in acquiring new weapon systems. Based on the analysis of inter-industrial relations, economical ripple effects are estimated with production inducing effects, value-induced effects, employment-induced effects and export-induced effects. Also, the technological ripple effects are estimated with technological intensity represented by investment cost in research and development. To show the validity of proposed methodology, a case study of acquiring new weapon systems such as GR (guided rocket), destroyer, and helicopter is accomplished. From the case study, it is concluded that these economical & technological ripple effects can be used as a reference to decision making in the course of acquiring major future defense weapons systems.

The purpose of this study was to investigate the relative effects of human capital and social capital on the economic well-being of late middle-aged Koreans. The data from the first wave of KLoSA (Korean Longitudinal Study of Aging) aged 50-64 were used (n=4,040). The major findings were as follows: First, human capital and social capital are both resources that can contribute to increasing the economic well-being of the middle-aged. Second, the relative contribution of human capital to the economic well-being of the middle-aged varied by the level of social capital, including formal network and informal network. Third, the relative contribution of social capital to the economic well-being of the middle-aged varied by the level of human capital, including employment type and educational attainment. Based on empirical results, the implications for social investment in human capital and social capital were provided.

Economic crisis in Korea since December 1997 had tremendously affected consumer behavior. This study examined consumer perception of the economic crisis and investigated its impacts on consumer ethnocentrism and purchase behaviors of foreign products. Two product categories of clothing and cosmetics were selected fro empirical testing. Data were obtained from a questionnaire survey to female consumers in Korea during September 1998, and 468 responses were analyzed. The consumer perception of the economic crisis(PCEP) scale was developed for the study. Correlation and regression analyses revealed: 1) the positive relationship between PCEP and consumer ethnocentrism(ETHN); 2) the positive effects of attitude toward foreign products(ATTI) on actual purchase of foreign products since the economic crisis(PB) and on purchase intention of foreign products(PI) for both clothing and cosmetics; 3) the negative effect of ETHN on PI for both product categories; and 4) the negative effects of PCEP on PB and PI for clothing.

This study analyzes the effect of macroeconomic indicators such as foreign direct investment (FDI), domestic investment, trade, inflation, unemployment, population, and governance indicators on economic growth and points out the GDP growth rate in 2002- 2019 among ASEAN countries. Data were compiled from the Worldwide Governance Indicators (WGI) and the World Bank, and the effect of variables on GDP was predicted using the pooled ordinary least squares (POLS), fixed effects model (FEM), and random effects model (REM) methods. As a measure of growth, the GDP growth rate has been taken; FDI and domestic investment, trade, inflation, and governance indicators are positively connected and have an influence on economic growth in these ASEAN countries; domestic investment, population, and unemployment have a negative relationship to economic growth. The macroeconomic indicators and institutional stability of the nation have an effect on its economic growth. Comprehensive institutional stability and well-laid macroeconomic policies are required for growth to materialize.

The purposes of this study are to examine the economic conditions and parenting of custodial fathers/mothers and to explain their impacts on the children's social adjustment after divorce. A total of 185 custodial parents divorced within the last 5 years completed a structured questionnaire. Children's social adjustment was the dependent variable in this study and was defined as their school performance and behavior problems. Results show that compared with divorced custodial fathers, divorced custodial mothers demonstrate more effective parenting, but there were no differences in economic conditions between them. In addition, children in single-father divorced families have lower school grades and more behavior problems than those in single-mother divorced families. Results also indicate that the economic conditions and parenting have different effects for children across family type. For children raised with a custodial father in divorced families, the economic conditions and the divorce duration are associated with lower school grades and behavior problems. For children with a custodial mother, however, the effective of parenting and the children's age have significant effects on the children's social adjustment after the parent divorced. Based on these results, this study proposes strategies for the improvement of children's adjustment in divorced families.
