This study aims at conducting a quantitative assessment of potential economic effects of the Regional Comprehensive Economic Partnership (RCEP) consisting of 10 Member States of the ASEAN, Australia, China, India, Japan, Korea and New Zealand using a multi-region, multi-sector CGE model. Three different policy scenarios are carried out based on baseline scenarios: China-Japan-Korea FTA (Scenario 1); ASEAN+3 FTA (Scenario 2); and the RCEP (Scenario 3). The impacts of three scenarios are described in terms of real GDP, Equivalent Variation as a measure of welfare, export and import volumes, trade balance, and terms of trade. This study finds that the RCEP is to lead to an increase in real GDP of all members of the RCEP, with Korea as a winner with a highest additional economic growth of 2.43 percent, which implies that Korea is in a better position to play a leading role in promoting the RCEP.

This study analyzed the impacts of FTAs (Free Trade Agreements) actively being promoted by the Korean government on the Korean economy, energy consumption and greenhouse gas (GHG) emissions and found the policy implications in terms of the linkage amongst them. The simulation analysis by using a global CGE model, KEEI-GCGE, found that the effectuation of Korea-USA, the Korea-EU and the Korea-China-Japan FTAs at the same time would increase the real gross domestic product (GDP) of Korea by 2.04%. In addition, the energy consumption and GHG emissions of Korea are estimated to increase by 3.33% and 1.53% respectively. These results imply that the various medium and long-term plans and policies related to energy and GHG emissions in Korea should systematically reflect those potential impacts of the FTAs.

The paper is concerned with, firstly, estimating the North Korean input-output table in which energy sectors like electricity and petro products are specified and, secondly, computing the effect of an investment in the energy sector on North Korean economy, by using the estimated input-output table and applying CGE analysis. The 4,000 million dollar investment on North Korean electricity industry produces 368 million dollar worth of output and 156 million dollar worth of value added. The 150 million dollar investment on petro industry creates about 20.5 million dollar worth of output and 9.65 million dollar worth of value added in North Korea.

아세안은 한중일과의 무역을 통한 경제적 연계의 심화현상과 최근 글로벌 위기로 인한 경기침체를 고려하여 새로운 경제성장추진을 위해 동북아의 한중일 삼국과의 무역자유화를 적극 추진하고 있다. 이미 ASEAN-중국, ASEAN-일본, ASEAN-한국 양자간 자유무역협정(FTA)이 발효되어 실행되고 있으며, 이들 3개 양자협정을 아우르는 A+3FTA(ASEAN+중국+일본+한국) 논의도 진행중이다. 이에 본 연구는 이들 4개 자유무역협정의 경제적 효과를 분석하여 과연 A+3FTA가 아세안은 물론 동아시아 역내에서 보다 바람직한 통상정책인지를 평가한다. 본 논문의 정성적 평가는 기존의 경제통합의 경제적 효과를 결정하는 이론에 근거하여 참여국의 제반 경제적 현황(경제규모, 소득수준, 경제개발수준, 거래비용, 무역 및 산업구조, 관세율 등)을 통계적으로 비교 분석한다. 한편 정량적 평가는 무역의 경제적 파급효과 분석에 널리 이용되고 있는 연산가능한 일반균형모형(CGE)분석방법을 적용한다. 정태적 효과의 분석을 위해서 GTAP 모형을 이용하며, 이와 더불어 동태적으로 투자를 통한 자본축적을 반영하는 자본축적 CGE 모형분석을 병행한다. 분석결과 후생 및 생산확대 측면에서 아세안의 경우 일본과의 양자간 FTA가 한국이나 중국과의 FTA에 비해 보다 긍정적인 후생증진을 가져올 것으로 기대되며, 아세안과 한중일 모두에게 A+3FTA가 동아시아 역내에서 보다 바람직한 자유무역협정이 될 것으로 평가된다.

We develop a hybrid model which allows the change in electricity generation mix by adding the electricity-sector components of bottom-up model to the conventional CGE model. The electricity sector is represented as a sum of separate generation technologies, each of which has the form of DRTS (Decreasing Returns to Scale) production function, unlike the conventional CGE model. We compare the effects of the 30% emission reduction target using the hybrid model with those using the conventional CGE model. The cost of meeting the target is lower with the hybrid model than the conventional CGE. It is consistent with previous studies in that adding the bottom-up components to the top-down model reduces the cost of emission reduction. In an extra analysis we find that an additional regulation like RPS (Renewable Portfolio Standard) increases the cost.

In a rapidly changing environment of international trade, the purpose of this study is to examine economic benefits and losses of each country involved in the negotiation on the Free Trade Agreement (FTA) in Northeast Asia and to prepare strategies for the negotiation in the FTA between Korea and China. Previous researches on FTA have been made mainly from the macroeconomic perspective. The approach in this study is a combination of regulatory, reviewing regulations, and economic making quantitative analysis of the economic effects of FTA, which are the basic background of FTA. In economic analysis, I estimated the macroscopic economic effects of FTA by examining the effects of FTA on the trade balance, GDP and production of focal countries through the Computable General Equilibrium(CGE) model using GTAP data set.

Hydrogen energy is emphasized as a substitutable energy of carbon-based energy system in the future, since it is non-depletable and clean energy. Long term vision of Korean government on the national energy system is to promote hydrogen energy by 15% of final energy demand until 2040. This study analyzes economic impacts of hydrogen energy development employing a dynamic CGE model for Korea. Frontier technology such as hydrogen energy is featured as slow diffusion at the initial stage due to the learning effect and energy complementarity. Without government intervention, hydrogen energy would be produced upto 6.5% of final energy demand until 2040. However, if government subsidizes sales price of hydrogen energy by 10%, 20%, and 30%, share of hydrogen energy would increase 9.2%, 15.2%, and 37.7% of final energy demand. This result shows that the slow diffusion problem of hydrogen energy as frontier technology could be figured out by market incentive policy. On the other hand, production levels of transportation sector would increase while growth rate of oil and electricity sectors would decline. Household consumption would be affected negatively since increase of consumption due to the price decrease would be overwhelmed by income reduction owing to the increase of tax. Overall, GDP would not decrease or increase significantly since total production, investment, and export would increase even if household consumption declines.

The objective of this study is to conduct a quantitative assessment of potential impacts on the Korean economy of Agreement on Trade in Services Under the Framework Agreement on Comprehensive Economic Cooperation Among the Governments of the Republic of Korea and the Member Countries of the Association of Southeast Asian Nations which was signed on 21 November 2007 using a Computable General Equilibrium (CGE) model. Tariff equivalents of services were calculated on the basis of concessions made in the Agreement between Korea and ASEAN member countries. The empirical analysis shows that Korea is to get an additional gain in real GDP of 0.04 percent and in welfare of US$106 million, with an increase in per capita utility of 0.03 percent. Total exports and imports of Korea are to rise by US$179 million and $191 million, respectively, causing a trade deficit of $12 million. Korea's exports to ASEAN member countries will increase by $108 million and Korea's imports from them will rise by $278 million, giving rise to a trade deficit of $170 million.

This paper analyzed what kind of institutional scheme for domestic policy instruments to reduce GHG emissions are desirable for Korea in complying with the international efforts to mitigate climate change, by focusing on independent abatement(equivalent to the imposition of carbon tax) and domestic emission trading. It also examined the economic and environmental implications of recycling the government revenue created from implementation of those policies. By utilizing a dynamic CGE model, this study shows that the economic cost under independent abatement is projected to be higher than that under emission trading. It is because under independent abatement scheme each emitter in economy must meet its emission target regardless of the abatement cost. On the other hand, emission trading allows emitters to reduce the marginal cost of abatement through trading of emission permits. In designing future domestic policies and measure to address the climate change problem in Korea, therefore, this study proposes the introduction of domestic emission trading scheme as the main domestic policy instrument for GHG emission abatement. In terms of double dividend, in addition, this study shows that both independent abatement and emission trading schemes under various assumption on the revenue recycling may not generate the double dividend in Korea.

fMRI, functional MRI introduced recently appears based on the gradient echo technique which is sensitive to the field inhomogeneity developed due to the local susceptibility changes of blood oxygenation and deoxygenation. Common to all the gradient echo techniques is that the signal due to the susceptibility effects is generally decreased with increasing inhomogeneity due to the $T2^*$ effect or conventionally known as blood oxygenation level dependent (BOLD) effect. It is, also found that the BOLD sensitivity is also dependent on the imaging modes, namely whether the imaging is in axial, or coronal or sagittal mode as well as the directions of the vessels against the main magnetic field. We have, therefore, launched a systematic study of imaging mode dependent signal change or BOLD sensitivity as well as the signal changes due to the tilting angle of the imaging planes. Study has been made or both TRFGE sequence and CGE sequence to compare the distinctions of the each mode since each technique has different sensitivity against susceptibility effect. Method of computation and both the computer simulations and their corresponding experimental results are presented.
