  • This study analyzes the contribution to the national economy of the stable water supply through managing multi-purpose dam. For the analysis, we consider 17 major multi-purpose dams and build a CGE model with summer water and winter water being the production factors as the base year of 2007. We analyze the economic impact of meeting water demand due to the dam management and estimate the risk premium of reducing the uncertainty of water supply. The analysis results show a significant production decrease in the industries of agriculture, forestry and fisheries and tap water as well as the food and beverage industry using the former industries' output as intermediates in the production and show an production increase largely in steel industry and electronic and electrical industries. Being compared to the benchmark solution, GNP is analyzed as being reduced by 0.22~0.68%. Meanwhile, the risk premium is estimated to be about 4 billion to 24 billion won for the value 01 the measure of relative risk aversion in the range 01 0.5 to 3.0.

  • This study aims at quantifying potential economic effects on the Korean economy of a China-Korea FTA and a Japan-Korea FTA using a dynamic computable general equilibrium (CGE) model. Most of the previous studies on them used static CGE models. Key findings of this study are that a China-Korea FTA would lead to a higher increase in Korea's exports and economic growth than a Japan-Korea FTA and that both a China-Korea FTA and a Japan-Korea FTA would cause additional trade deficits to Korea, which would be minuscule compared to Korea' economic trade volume. Since potential economic impacts on Korea's industry output and exports by sector of a China-Korea FTA and a Japan-Korea FTA are forecast to be complementary, i.e., major sectors which would run trade deficits from a Japan-Korea FTA would run trade surpluses from a China-Korea FTA, a simultaneous pursuit of both a China-Korea FTA and a Japan-Korea FTA would be more desirable and beneficial to Korea. This study shows that a dynamic CGE model which can take explicit account of international capital mobility and ownership is required for more precise estimation of effects of the FTAs.

  • We investigate a practical method of calculating the impact of multiple domestic energy price change on the final demand, production, the export and import change, the change in the balance of payment of Korean economy. By combining an existing computable general equilibrium (CGE) model with the traditional input-output analysis with two additional assumptions on the price behavior, we provide a cost-effective method of analyzing the impact of multiple energy price changes on the domestic economy. The energy price shock we used in this paper is 0.127% increase weighted by the sectoral productions. The total impacts on price level and GDP are 1.258% and -0.940%, respectively. The impact on the total output (GDP and intermediate goods) is about -1.580%.

  • This paper analyzes the impact of imposing carbon tax on the Seoul economy to reduce Greenhouse Gas(GHG) emission. We construct the social accounting matrix of Seoul, specifying energy and transport sectors which is closely related to air pollution. Then, we formulated the computable general equilibrium (CGE) model of seoul and performed scenario analysis. The main result shows that the economic cost of GHG reduction is quite large but the health benefit is also considerable. It also suggests the importance of cost effective measures such as the development of new energy technology and the improvement of energy efficiency.

  • The objective of this study can be presented as follows: First, given the consumption-based carbon accounting method which has now been claimed, this study reviews the emissions within Korea and the resulting position change in international society. Second, when each nation makes efforts to reduce carbon emissions under the Copenhagen Accord, this study, using the Computable General Equilibrium (CGE) model, reviews the resulting carbon leakage and analyzes the effect from the various border adjustment measures. However, reflecting uncertainties in the negotiation processes, this study attempts to apply scenarios with regards to the reduction-mandatory nation group. In addition, this study tries to observe the impact on Korea through testing the various border adjustment measures, including the free allocation and embodied carbon tariffs.

  • This study aims to conduct a quantitative assessment of potential economic impacts on the Korean economy of the concessions of the Korea-U.S. FTA (KORUS FTA) which was signed on April 1, 2007 using a dynamic computable general equilibrium (CGE) model, with all sectors, including agriculture, manufacturing sectors and services industry, considered for simulations. In addition, the timing of trade liberalization based on the concessions agreed on in the KORUS FTA talks for all sectors is explicitly considered. Major findings of this study are that Korea' real GDP would rise by 4.67%~4.99% by 2023 and the contribution of liberalization of services trade to Korea's economic growth would be 0.3%~0.62% points. Trade liberalization in service sectors would lead to lowered import prices and an increase in FDI, which are to contribute to an higher output and exports of sectors which make an intensive use of imported inputs and finally a higher economic growth of the Korean economy as a whole. For that to happen, a ratification of the KORUS FTA by the National Assembly of Korea and the U.S. Congress is required.

  • The voluntary mid-term greenhouse gas(GHG) emission reduction targets for 2020 among major developed and developing countries were evaluated by using the global computable general equilibrium(CGE) model. The GHG emissions of developed countries were estimated to be reduced by 14.0% from 1990 level, which implies that the GHG reduction targets of developed countries should be strengthened to reach agreement in future post-Kyoto negotiations. The voluntary participation of developing countries for GHG emissions reduction contributed to global GHG emissions reduction by 15.9% from 1990 levels, which were led by the participation of China and India. These outcomes imply that the reinforcement of GHG emission reduction targets in developed countries and the wider participation of developing countries will be necessary for the environmental effectiveness of the post-Kyoto regime. Emissions reduction based on voluntary targets will decrease the global real GDP by 1.18%.

  • 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.

  • Although coal has been utilized as major fuel, it is known as 'most climate unfriendly' fuel. Carbon tax or tradable permit policy has been discussed as major measure for reducing production and consumption of coal, but it might be more efficient to remove subsidy on coal production and consumption. This study examines economic and environmental effects of recycling revenue from reducing subsidy on the use of coal to foster climate friendly fuel (ligneous biomass) by price subsidy or increased public expenditure. A static CGE model was applied to analyze the welfare consequences and economic impacts of two policy measures. The result shows that price subsidy policy is more desirable than creation of public demand in terms of welfare as well as overall economic impacts.

  • In this study, I focus on analyzing how the effects of implementing ETS are different depending on whether Korean ETS linking with carbon markets in other countries. The global computable general equilibrium (CGE) model built in this study analyzes the chages in the production and trade of industrial sectors according to the international linkage of ETS compared to the reference scenario of emissions reduction targets and implementation of ETS. From the analysis of internatioanl linkage of carbon markets scenarios, Annex B countries-South Korea carbon market linkage with individual ETS in China worse the economic outcomes in South Korea the most. This means South Korea lose the international competitiveness compared to China in this scenario. On the other hand, Annex B-China carbon market linkage with Korean individual ETS implementation reduce the decreases in production and trading. The most effective way is to join a global emissions trading market with China. The results are consistent in most industries of South Korea. These results are caused by that the supply of emission allowance is increased and the price of emissions allowances is dropped by China's participation to the carbon market, which can be understood to reduce the carbon reduction cost for industrial sectors. In addition, it can be also concluded that the determinant of the negative impact of ETS on changes in production and trade is more sensitive to the price of emissions allowances than to the characteristics of production and trade structure.
