This paper analyses carbon emissions and value-added embodied in trade between two large developed countries, South Korea and the United States, during 2000-2014. Using multi-regional input-output (MRIO) tables, our analysis reveals that carbon emissions and value-added embodied in exports grew by 19% and 101% for South Korea but shrank by 43% and 7% for the United States. As a result, South Korea experienced a 40% increase in net carbon exports and 243% increase in net value-added exports. At the industry level, the primary drivers of changes in carbon exports were electricity and basic materials. The majority of industries in witnessed improvements in carbon intensities suggesting improved environmental efficiency. While both countries achieved a decoupling of carbon emissions from value-added exports, substantial year-to-year and sectoral variations were observed. Finally, structural decomposition analysis indicates that domestic supply-side factors played a role in decreasing emissions whereas foreign demand-side factors contributed to emissions increases. In line with the main findings, various implications for policy and future research are discussed.

This paper approaches knowledge capital as social infrastructure and analyzes its impact on economic growth. To this end, we constructed a panel dataset for 120 countries for the years 2000-2014 and estimated the economic growth function using the panel analysis. As proxies for knowledge capital, we used the R&D expenditure per capita and the number of patent applications per thousand people in each country, both measured in stock. Economic growth was measured in terms of real GDP per capita and real value added per capita at the industry level. The empirical findings demonstrate that knowledge capital accumulated in a society significantly promotes economic growth. Especially R&D stock increases real value added per capita in all industries-not only manufacturing, but also services and agriculture-implying substantial inter-industry spillover effects. The findings of this study suggest that knowledge capital boosts economic growth as core social infrastructure.

The purpose of the study was to examine early childhood teachers' content knowledge of economic education. The subjects, 60 early childhood teachers, were asked to draw concept maps about early childhood economic education. Their concept maps were analyzed in terms of superordinate and subordinate concepts by contents and frequencies. The results were as follows. First, 248 superordinate concepts were shown, and they were categorized into nine representative terms: 'Scarcity and Choice,' 'Decision Making,' 'Monetary Value,' 'Production,' 'Consumption,' 'Distribution,' 'Restrain,' 'Reuse,' and 'Economic Education Activity.' Second, 1,440 subordinate concepts were shown, and 'coin,' 'bill,' 'saving,' 'bank,' and 'money' were frequently shown. Third, the mean numbers of subordinate concepts per superordinate concepts showed that early childhood teachers had more knowledge about 'Consumption,' 'Monetary Value,' and 'Economic Education Activity' than other superordinate concepts. The results showed the need for early childhood teachers to have more systematic and hierarchical pedagogical content knowledge on economic education.

This study aimed to investigate the influence of fashion lifestyles and consumption values on the difficulty of discarding unused fashion products. To achieve this purpose, this study surveyed female consumers aged 20s-50s to gain empirical analysis in July 2018. Data were analyzed for 236 subjects who were selected through online and offline sampling. The results were as follows. First, consumers tend to have difficulties discarding unused fashion goods. Consumers that have a higher income tend to have greater difficulty when choosing to discard items. Factors influencing the difficulty in discarding items were emotional attachment, usefulness in the future, economic value, and the lack of organizing skills. Usefulness in the future and the lack of organizing skills are the most significant factors influencing the discarding difficulty. Second, discarding difficulty had a significant relationship with fashion lifestyle, indicating that consumers seeking a fashion lifestyle that purchase more expensive brands tend to have more difficulty when discarding items. Third, each factor had a meaningful relationship with fashion goods consumption values. Those pursuing conspicuous value showed a greater difficulty discarding items due to emotional attachment, economic value, and lack of organizing skills. Pursuance of situational value showed a higher discarding difficulty than economic value factors. Pursuance of practical value showed a higher difficulty than both usefulness in future situations and economic value factors. Pursuance of differentiation value showed a higher discarding difficulty than emotional attachment and usefulness in the future factor. This study will help understanding consumers psychological mechanisms that experience difficulty in terms of the discarding of unused fashion goods.

World Business Council for Sustainable Development(WBCSD) is effort to achieve sustainable development in economic growth, environmental preservation and social development. Being this way, it is essential for developing evaluation tool which quantify to fulfill sustainable development. Eco-efficiency is one of the quantitative tools to evaluate environmental impact and economic aspect. Eco-efficiency, in general term, means creating more value of product or services with less impact to environment. It indicates as environmental impact in denominator and value of product or services in numerator. Eco-efficiency shows how much economic value reveals to unit environmental impact caused by product or service as an indicator. This study aims at developing eco-efficiency indicator of railway industry considering use stage among the entire life cycle stage of KTX and Saemaul train and also, figure out eco-efficiency value through indicator. Therethrough, it is enables to evaluate created value per environmental aspects. Since rail vehicles demands a lot of energy to transport people during use stage, the environmental impact is more significant than other lkfe cycle stages. Therefore, it quantified environmental indicator as CO2 emission and economic indicator as transportation record per a year with an annual income. This study contributes to be used as a tool for quantifying indicator of comparison evaluation in respect of rail vehicle in use stage.

본 연구는 경제적 가치와 환경가치를 유기적으로 결합시키는 행복경제학적 접근을 적용하여 자연관과 효용의 관계를 비교하고자 한다. 회귀분석을 수행한 결과 다음과 같은 사항을 발견할 수 있었다. 첫째, 본 분석에서는 자연관에 따라 행복함수 형태가 다르다는 것을 실증적으로 확인하였다. '인간중심적 자연관'의 가치체계는 경제가치중심이며 환경, 신뢰와 같은 비 물질가치 요소가 무시할 정도로 낮은 것임을 통계적 유의도를 통하여 알 수 있다. 둘째, '생태중심적 자연관'은 경제를 포함한 환경, 사람신뢰를 동시에 고려하는 중층적 가치체계를 가지고 있다고 할 수 있다. 그들의 가치체계에 따르면 인간의 편의와 경제적 가치에 치우친 행위는 행복극대화 관점에서 합리적이지 않다는 점을 분석 결과에서 알 수 있다.

PURPOSES : This study evaluates the economic value of national highway construction projects using Real Option Pricing Models. METHODS : We identified the option premium for uncertainties associated with flexibilities according to the future's change in national highway construction projects. In order to evaluate value of future's underlying asset, we calculated the volatility of the unit price per year for benefit estimation such as VOTS, VOCS, VICS, VOPCS and VONCS that the "Transportation Facility Investment Evaluation Guidelines" presented. RESULTS : We evaluated the option premium of underlying asset through a case study of the actual national highway construction projects using ROPM. And in order to predict the changes in the option value of the future's underlying asset, we evaluated the changes of option premium for future's uncertainties by the defer of the start of construction work, the contract of project scale, and the abandon of project during pre-land compensation stages that were occurred frequently in the highway construction projects. Finally we analyzed the sensitivity of the underlying asset using volatility, risk free rate and expiration date of option. CONCLUSIONS : We concluded that a highway construction project has economic value even though static NPV had a negative(-) value because of the sum of the existing static NPV and the option premium for the future's uncertainties associated with flexibilities.

This study was designed to examine the effects of housing values on housing satisfaction model. The empirical model of this study was based on the Goulart(1982). Data were collected through questionnaire survey, and the sample consisted of 285 households in Kimhae. Housing values were grouped into four clusters : the health and convenience value, the personal and social value, the location value, and the economic value. The major findings were that 1) the concordance between values and the actual housing conditions contributes significantly to the prediction of housing astisfaction, and 2) the control variables including sociodemographic and economic characteristics and housing values themselves did not directly influence on housing satisfaction.
