국제 전화 서비스 제공자들은 송신 및 수신 네트워크 사이에 통화 수입을 어떻게 배분할 것인지를 결정해야 한다. 국제 전신전화 자문위원회(CCITT)는 이 문제에 관해 상세하게 서술하고 있다. 그러나 이것은 단지 정산문제에만 국한되는 것은 아니다. 요율은 또한 운용업자 자신에 대한 가격 정책을 고무시키고 적절한 요율을 통해 올바른 동기를 창출해내는 것이 효율적인 결과를 유도하는데 있어서 중요하다. 이 글은 최적의 요율에 대한 사항을 CCITT 권고사항과 비교하기 위해 쓴 것이다. 요약하자면 최적의 요율이란 회선당 고정요금에 통화량당 가격+고정부품 대체를 합한 것이고, 적정 요율은 시간의존적으로 수요가 많은지 적은지의 여부와 관계가 깊다. 이러한 특성은 현재의 절차가 얼마나 비효율적인가를 평가해 주고 있다. 부연설명하자면, 결과는 통신 서비스의 범위가 넓은 경우에 적용되고 있다.

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.

This paper is designed to investigate the dynamic structure of optimal tariff imposed by the oil importing country from OPEC when OPEC increases the oil reserves through exploration and development. For this purpose, we used a Stckelberg differential game modeling approach, and tried to analyze two cases such that the one is the extraction cost is dependent on the oil reserves and the other is the extraction cost is independent of it. On the basis of this analysis, we propose that the importing contry has to impose dynamically inconsistent tariffs if the extraction cost is dependent on the oil reserves. Otherwise, she should impose dynamically consistent tariffs announced at initial time. In addition, we found that whether or not the exporting country uses some portion of oil produced for domestic consumption does not affect our policy proposition stated above.

Free Trade Agreement(FTA) aims at abolishing tariffs on trade among nations or regions resulting in having a significant impact on maritime transportation and port. Korea made the first FTA with Chile in 2004 and the trade volume between two countries has seen significant increase. The literature on such impact, however, seems to be very limited. The main purpose of this study is, therefore, to analyze the impact of Korea-Chile Free Trade Agreement on the imported container throughput from Chile at the Busan Port. For this both cross-sectional and time series data are collected that comprise container throughput, Gross Domestic Product (GDP), import tariff, and maritime freight rate, from 2000 to 2011, and the gravity model is applied. The main result of the study shows that the dependent variables, GDP and import tariff are statistically significant, but the maritime freight rate is not consistent with regarding to statistical significance and parameter sign.

Purpose - The global trend of protectionism has expanded since the onset of US President Donald Trump's administration in 2017. This global phenomenon has led to a significant reduction in world trade volume and a negative impact on economic development in some countries where the external sector accounts for a large proportion of GDP. Although Korea is a country vulnerable to this deteriorating trade environment, few studies have examined the relationship between protectionism and its business cycles based on Korean data. Thus, this paper investigates the impact of protectionism on Korea's business cycle. Design/methodology - To identify future implications, we conduct a structural vector autoregression (VAR) analysis using monthly Korean data from 1994 to 2015. Macroeconomic variables in the model include the industrial production index, inflation rates, exports (or net exports), interest rates, and exchange rates. For the identification of the shock reflecting the expansion of protectionism, we use an antidumping investigation (ADI) data. Since ADIs are followed generally by the imposition of antidumping tariffs, they have no contemporaneous impact on tariffs and are also contemporaneously exogenous to other endogenous variables in the VAR model. We examine two kinds of ADI shocks i) shocks on Korean exports imposed by Korea's trading partners (ADI-imposed shocks) and ii) shocks on imports imposed by the Korean government (ADI-imposing shocks). Findings - We find that Korea's exports decline sharply due to ADI-imposed shocks; the lowest point at the third month after the initial shock; and do not recover until 24 months later. Simultaneously, the inflation rate decreases. Therefore, the ADI-imposed shock can be regarded as a negative shock on the demand curve where both production and price decrease. In contrast, the ADI-imposing shock generates a different response. The net exports decline, but the inflation rate increases. These can be seen as standard responses with respect to the negative shock on the supply curve. Originality/value - We shed light on the relationship between protectionism and Korea's economic fluctuations, which is rarely addressed in previous studies. We also consider the effects of both protective policy measures on imports to Korea imposed by the Korean government and on policy measures imposed by Korea's trading partner countries on its exports.

Purpose - This study deals with a strategic plan for meeting the value added criteria effectively, which is one of the methods of determining origin used in preferential trade such as FTA. Automobile products, one of the major Korean export items, were selected to give a practical use against the FTA requirements. Design/methodology - This study is based on the value-added criteria of the Korea-US and Korea-EU FTAs that apply various value-added criteria. The Korea-US FTA adopts the RVC method based on the integration, deduction and net cost methods, while the MC method is employed in the Korea-EU FTA. The methodology used in this work is an extended literature review, analysis of the value-added criteria applied to automobile products under Korea-US and Korea-EU FTA with some secondary statistics. Findings - Based on in - depth analysis of the value - added criteria requirements for automobile products stipulated in the Korea - US FTA and the Korea - EU FTA, two strategic considerations are suggested. First is 'appropriate value-added strategy' and the second is 'strategy of changing production and trade structure'. The second strategy is a bit used in Korea but this is not considered best if the first strategy is ignored or forgotten. The second one is meaningful when this becomes inevitable. Research limitations/implications - This study is primarily designed to assist Korean auto mobile industry players exporting to EU and USA but this may help to auto part or material producers in FTA counter party territories being EU or USA as the preferential tariffs are applied on a inter region basis. A further research other than auto mobiles using other major FTAs might be followed later. Originality/value - There has been so far little research on strategic factors to meet the value-added origin requirements. This study, therefore, is expected to contribute facilitating the decision of FTA origin and to improve the utilization of FTA by allowing exporting companies using value added criterion to more smoothly meet origin requirements. This will also enable the tax authorities to utilize the value-added criterion to validate effectively the origin of imports where preferential tariffs are applied.

Global trade protectionism has increased further and U.S. priorities and protectionism have strengthened since Trump took office in 2017. Trump administration is actively implementing tariff measures based on U.S. domestic trade laws rather than the WTO rules and regulations. In particular, the American government has recently been imposing high tariffs due to national security and imposing economic sanctions on other countries' imports. According to the U.S. Trade Expansion Act Section 232, the American government imposed additional tariffs on steel and aluminum imports to WTO member countries such as China, India, and EU etc. on march 15, 2018. Thus, this study aims to investigate whether the U.S. Trade Expansion Act Section 232 is consistent with GATT/WTO rules by comparing the legal basis of US / China / WTO regulations related to Section 232 of the U.S. Trade Expansion Act, and gives some suggestions for responding to the Section 232 measure. As the Section 232 measure exceeded the scope of GATT's Security Exceptions regulation and is very likely to be understood as a safeguard measure. If so, the American government is deemed to be in breach of WTO's regulations, such as the most-favored-nation treatment obligations and the duty reduction obligations. In addition, American government is deemed to be failed to meet the conditions of initiation of safeguard measure and violated the procedural requirements such as notification and consultation. In order to respond to these U.S. protection trade measures, all affected countries should actively use the WTO multilateral system to prevent unfair measures. Also, it is necessary to revise the standard jurisdiction of the dispute settlement body and to explore the balance of the WTO Exception clause so that it can be applied strictly. Finally, it would be necessary for Chinese exporters to take a counter-strategy under such trade pressure.
