This study is to analyze the economic effects of tariff reduction using computable general equilibrium(CGE) model. We set up the social accounting matrix for five-base equilibrium year. Our main findings are as follows. First, the impact of tariff reduction on GDP was different from time to time. It meas that the differentiated economics structure was affected by tariff reduction. As our economic grew up, the impact of tariff reduction was measured much higher. Second, until 1995 the impact of tariff reduction on total export and import was increased, then while 1995 the increase was dropped. This is because we reduced the tariff by the WTO negotiations. Third, the tariff reduction affected the price of imported goods, so it contributed to substitute effects between domestic and imported goods. According to these results, we found out the importance of the linkage between the tariff reduction and economic structure.

This study was analyzed the changes of the tariff reduction for the timber products according to the modalities proposed by the chairman of Non-agriculture Market Access. The resulted data would be expected to be used for establishing the strategies for the WTO/DDA negotiation of Korea. As WTO/DDA negotiation was officially resumed in the early 2007. It was necessarily required to develop a strategy how to address debating core issues raised during the negotiation since 2006. For this purpose, major core issues and agenda were arranged and analyzed in this study. In Korea, the results of the analysis show that, in the position of developed members, the applicable tariff rates after the tariff reduction of sawnwood and veneer sheet was not different from that in 2007. However, in the position of developing members, the applicable tariff rate of sawnwood and veneer sheet was increased after the tariff reduction. The unbound tariff lines, wood-based panels such as plywood and medium-density fiberboard, the applicable tariff rate after the tariff reduction was analyzed to be reduced more than 50% in the position of developed members, and therefore is determined to be considerable influenced upon the applicable tariff rates. On the other hand, in the position of developing country the tariff rates after the tariff reduction was higher than that of the applicable tariff rates in 2007. Thus no changes of the tariff reduction by a negotiation agreement was analyzed to be happened.

Purpose - This study examined the effect of tariff cuts on productivity in Korea's manufacturing industries and the effect of initial productivity level before tariff cuts on productivity improvement after tariff cuts. We also attempted to identify whether import-driven or export-driven factors are more important for productivity improvement, especially in low productivity industries. Design/methodology - Since tariff reduction is a policy decision that can affect cross-industry, its impact is spread across all industries beyond the scope of a single firm through the input and output network of industry structure. Accordingly, we proposed a new method to measure the change in productivity to reflect the impact of tariff cuts across industries. Through an Armington CGE analysis, changes in endogenous variables can be directly measured after the exogenous shock of tariff reduction, and the amount of movements in productivity triggered by tariff cuts can also be calculated. We can thus assess the effectiveness of exogenous policy, such as tariff cuts, through the difference between the benchmark and counterfactual values of endogenous variables. Findings - This study confirmed that tariff reduction positively affected productivity improvement in Korea's manufacturing industries. It also confirmed that productivity gains occur in Korea's leading export industries. Finally, greater productivity gains were recorded in the group with additional high-export-share or high-import-share conditions for low productivity industries. These results are, in a limited sense, consistent with the existing studies that emphasize the importance of exports and imports on productivity improvement, especially for low productivity industries. Originality/value - The results of our experiments are different from those of non-CGE studies, which measure the industry-level change in productivity with dummy coefficients, in terms of directly calculating the amount of change in productivity. In addition, we propose that the Armington CGE model is more appropriate than the Melitz CGE model to directly measure the productivity after tariff cuts. This is because the Melitz CGE model assumes the given specific productivity density, which does not change after an overall drop of tariffs. To the best of our knowledge, this approach to directly calculating productivity by reflecting the impact of tariff reduction across industries through CGE analysis, is unprecedented in this literature.

This paper characterizes the optimal reciprocal trade policy in the environment of Melitz (2003) with firm productivity heterogeneity. In particular, without making parametric assumptions on firm productivity distribution, this paper derives the optimal degree of reciprocal tariff reductions that maximize the world welfare. A reciprocal import subsidy raises the industry productivity, lowering aggregate price; a reciprocal import tariff helps correct the markup distortion, increasing nominal income. With all the conflicting effects of import tariffs on welfare considered, the optimal degree of reciprocity in multilateral tariff reduction is shown to be free trade.

For saving electricity bill, energy storage system(ESS) is being installed in factories, public building and commercial building with a Time-of-Use(TOU) tariff which consists of demand charge(KRW/kW) and energy charge(KRW/kWh). However, both of peak reduction and ESS special tariff are not considered in an analysis of initial cost payback period(ICPP) on ESS. Since it is difficult to reflect base rate by an amount of uncertain peak demand reduction during mid-peak and on-peak periods in the future days. Therefore, the ICPP on ESS can be increased. Based on this background, this paper presents the advanced analysis method for the ICPP on ESS. In the proposed algorithm, the representative days of monthly electricity consumption pattern for the amount of peak reduction can be found by the k­means clustering algorithm. Moreover, the total expected energy costs of representative days are minimized by optimal daily ESS operation considering both peak reduction and the special tariff through a mixed-integer linear programming(MILP). And then, the amount of peak reduction becomes a value that the sum of the expected energy costs for 12 months is maximum. The annual benefit cost is decided by the amount of annual peak reduction. Two simulation cases are considered in this study, which one only considers the special tariff and another considers both of the special tariff and amount of peak reduction. The ICPP in the proposed method is shortened by 18 months compared to the conventional method.

The health industry of China is faster than before, so it will be rank 5th at world-wide markets in 2010. Firstly, the custom tariff was lower at 15% in 2000 and at 10.4% on June 2005. And, it will be lower into 9.8% in 2010. Secondly, this is because of expansion of purchase power on increase in economic growth, extended human life expectancy. As it is entered the WTO in January 2002, it will positively affect on export of Korea for China. This paper focuses on the analysis of export increase caused by reduction of custom tariff in China. As above mentioned, the time schedule on average reduction of custom tariff was 15% in 2000, 10.4% in 2005. Then, it will be lower into 9.8% in 2010. As the empirical test related health industry, it presents 19.80% export increase rate for China of Korea on reduction of custom tariff from 2001 to 2010. The exporting of drug for China will be up to 17.85% for 10 years. Also, the exporting of Biomedical will be up to 20.99%, and respectively 22.95%, 22.60% in Cosmetics and food industry. Conclusionally, the exporting of this health industry will be increase greatly, compared with any other industries. So, it is necessary that firms increase in R&D investment and government support as policy for health industry.

Purpose - This paper examines how differently output and input tariffs affect domestic employment across industrial characteristics of comparative advantage such as labor quality and capital intensity. Design/methodology - The paper focuses on 453 Korean industries from 2007 to 2014 because Korea is a typical example of a natural resource-scarce open economy and experienced the transition of the export pattern from labor intensity to technology intensity during this period. Findings - The results show that input tariff reduction stimulated total employment, focusing on the early 2010s, while the effects of output tariff reduction were statistically insignificant in general. However, the stimulation effects of output tariff reduction on employment were found in comparative advantage industries with greater labor quality and capital intensity. As for input tariff reduction, its stimulation effects on employment were more prominent in comparative disadvantage industries with lower labor quality and capital intensity. Originality/value - These results provide significant implications for natural resource-scarce open economies which are experiencing the transition of the export pattern from labor intensity to technology intensity and the unequal distribution of income after trade liberalization: imported intermediate inputs has become increasing important, leading to trade effects on employment and alleviation of income inequality.

This study firstly aims to review the discussions among major nations and international organizations on removal of tariff wall in EC. Secondly, it is analyzed how the trend of tariff reduction of removal will affect an individual economy in a partial balance analysis model on an assumed small-size economy. In closing, political implication for removal of tariffs in EC will be presented. The study concluded that tariff removal on Internet EC has both positive and negative effects on the importing economy. It can improve the efficiency in utilization of economic resources by the importing economy in the long term while cut the financial revenue and aggravate the trade balance of importing country. It is inferred from such a conclusion that tariff removal can lead to trade imbalance between the Information haves and the have-nots.

We have analyzed the trade effect of Korea-EU FTA on the Korean fishery sector, after reviewing the trade pattern and the tariff barriers of fishery sector between Korea-EU. For the trade effects, we have categorized into three cases: 1) the complete tariff elimination of all items, 2) the half tariff reduction on top ten valued items, with complete tariff elimination of other items, and 3) the complete tariff elimination, except unbinding top three valued items. The effect of the complete tariff elimination of all items implies the effect of the full achievement of FTA. For other two cases, these effects imply the effects of the transitional phenomenon of FTA since the complete tariff elimination happens gradually over more than ten years. For the complete elimination of tariff, we found that imports are increased by 1.1 billion dollars which is 12.9% increase in average imports during years 2006-2009. Also, exports are increased by 1.3 billion dollars which is 14.5% increase in average exports during same years.

This study analyzed core issues addressed in the tentative agreement of WTO ministerial meetings held to finish WTO/DDA negotiations in Geneva in July 2008. The objectives of this study are to analyze changes in tariff reduction on timber products, and their influence on demand and supply of the items according to the modality of Non-Agricultural Market Access (NAMA) and to provide basic information for strategy formulation of our country for further WTO/DDA negotiations. The results indicate that there will not be significant changes in the tariff on sawnwood and on veneer sheets, however, the tariff on plywood need to be cut by around 50% from the applicable tariff rates of 2008 on condition that our country is in the position of developed countries. Therefore, the item of plywood is expected to be influenced greatly according to the change in tariff reduction. From the analysis of influence of tariff reduction on the demand and supply of timber products including sawnwood and wood based panels, such as plywood, particleboard, and fiberboard, the import quantities of the items are expected to be changed from 0.8% to 13.3% if our country is in the position of developed countries, however, they are expected to decline by 0.8%~44.3%, if our country is in the position of developing countries (22, coefficient for developing members).
