Purpose - This research investigates the effect of disclosure quality with two main components, reliability and timeliness, on economic value added in Iran. Research design, data, and methodology - The sampling includes 170 Tehran Stock Exchange listed companies from 2008-12. Multiple regression analysis was applied to test the hypotheses and estimates of the coefficients. Firm size and return on assets were the control variables. Results - The results show that timeliness of information has a positive impact on economic value added. We did not find any significant relationship between disclosure quality and reliability of information and economic value added. The regressed model shows that there is no significant association between firm size and economic value added. The results also show that there is a positive association between return on assets and economic value added. Conclusions - Theoretically, timely information is effective in decision-making. This study shows that timeliness of information has positive effect on the creation of economic value added. However, disclosure quality, reliability, and firm size do not effect on economic value added. Companies with greater return on assets produce greater economic value added.

Purpose - The purpose of this study is to evaluate the economic effects of FTAs using the concept of value-added exports. So far, the economic effects of FTAs have been dependent on decrease in import prices due to tariff cuts in importing countries, but the actual tariff reduction need to consider the value added of the exporting countries. Design/methodology - Value-added export refers to the added value created in the exporting country out of total exports. Among value-added exports, direct value-added export is interpreted as the Regional Value Contents (RVC), from which the economic effect of the FTA can be analyzed. A modified GTAP-VA model takes into account RVC in order to estimate accurate effects of FTAs. Findings - By the re-evaluation of the FTA based on the RVC, this paper makes it clear that the economic effects of the existing FTA methodology have the possibility of overestimation. In addition, as a new FTA with a strengthened Rules of Origin (ROO) is being initiated, a negative impact on international trade and GVC utilization may occur. Originality/value - This study introduces the concept of value-added export in analyzing the effects of FTAs. The new analysis methodology of this paper emphasizes the importance of value-added exports. Re-organization of GVCs would change regional trade agreements and empower ROO by weakening existing GVCs and transforming the value chain from global into regional scope.

본 연구는 OECD-WTO의 부가가치 기준 무역(TiVA) 데이터를 이용하여 경제통합이 부가가치 기준 무역에 미치는 영향을 분석하였다. 연구결과 경제통합은 회원국간의 무역을 통계적으로 유의하게 증가시키는 것을 확인하였다. 이는 전통적 의미의 최종재와 중간재뿐만 아니라 수출에서 차지하는 국내 및 외국의 부가가치 규모도 증가하는 것을 확인하였다. 아울러 경제통합이 국내 및 외국의 부가가치 무역을 증가시키는 효과가 대체로 비슷하여 총수출에서 국내부가가치가 차지하는 비중을 증가시키거나 감소시키지 않는다는 것을 확인하였다.

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 study aims to quantify the value of origin among CPTPP and Korea, under the assumption that the 'cumulation' clause has large economic effects in multilateral FTAs and increase the possibility of improving FTA utilization. Analysing the relationship between value-added exports and FTA utilization rate, there is a positive correlation between the two variables, and the cumulation of multilateral production of CPTPP is expected to increase Korea's value-added exports. In the GTAP-VA model, the target of cumulation is calculated as 'Domestic Value Added', and all value-added of CPTPP are cumulated in the form of value added exports of exporting country. When Korea participates in CPTPP, it is possible to cumulate additional 6.3~9.6% value added, and the agreements with low FTA export utilization rates such as New Zealand, ASEAN would have greater economic effects of cumulation. For the successful implementation of CPTPP in Korea, it is necessary to develop a new origin verification system that enables multilateral value-added cumulation. It is time to seek cooperation with countries currently participating in CPTPP to prove the value added inherent in CPTPP-originating products.

Over the last three decades, nuclear technology development has played a vital role in the socio-economic development of the Republic of Korea. This study, being the first of its kind, focuses on quantifying the actual economic contribution of nuclear technologies to economic development by evaluating the net benefit of the nuclear power with respect to the country's Gross Domestic Product (GDP). An input-output analysis was employed as a methodological approach to analyze inter-industrial economic activities by calculating the industrial value added as a means of the economic contribution during the period of 1980 to 2005. The industrial value added of nuclear technologies was estimated from the construction and operation of nuclear power (backward-linked industrial value added) and from the industrial activities attributed to the electricity generated by the nuclear power (forward-linked industrial value added). It was found that the total net contribution of nuclear technologies as a percentage share of GDP amounted to 2.38% in 2005.

현대 세계 경제 체제의 주요 특징인 글로벌 가치사슬은 주로 선진국에 의해 주도되어왔고 개발도상국은 상대적으로 저부가가치 활동을 담당함에 따라 가치분배의 지리적 불균형이 발생하였다. 그러나 이러한 가치분배의 불균형은 점차 완화되기 시작하였는데, 이와 같은 변화에 영향을 미치는 요인을 분석하는 것이 본 연구의 목적이다. 연구 목적의 달성을 위하여 다양한 영향요인 중 글로벌 가치사슬에서의 산업 업그레이딩 방식에 초점을 맞춰 개발도상국의 부가가치 획득에 미치는 영향을 분석하였다. OECD 부가가치 기준 교역자료(TiVA)의 전산업, 식료품·담배산업, 섬유·의류 산업, 컴퓨터·전자산업, 자동차산업을 대상으로 패널분석을 실시하였다. 분석결과 전산업의 경우 개발도상국의 부가가치 획득은 총생산량을 증가시키고 고부가가치 제품을 생산하며 전방참여도를 높일수록 증가하는 것을 확인할 수 있었으며, 세부 산업별 분석결과는 산업별 특성에 따라 조금씩 다른 양상으로 나타났다.

The purpose of this study is to estimate regional economic effects of spatial diffusion of wildfire using Cobb-Douglas production function of agriculture and forestry. The analysis is applied to Gangwon and Gyeongbuk provinces where are the most damaged of wildfire in Korea. The damaged areas are derived from multiplied by the occurrence probability of wildfire and diffusion areas of wildfire for micro-spatial unit level with ArcGIS techniques. The models of wildfire provides that the spatial diffusion of wildfire increases with the rising of highest temperature and average wind speed. Through the production function, value added of Agriculture and Forest sectors get damaged where the Cos-converted slope aspect of mountains are toward the South. The production model provides reductions of regional value added by increasing damaged areas of wildfire. It reveals that the most damaged region is Andong city in Gyeongbuk province, where value added loss is 1.25 billion Won, which is about 0.72% of total value added in agriculture and forestry of the city. As a view of policy makers, it needs to be considered to establish prevention policies against wildfires because regional economic losses from wildfire are depending on geographical conditions and performances of the major industry related to wildfire's diffusion such as agriculture or tourism sector according to the result of analysis.
