한미 FTA 재협상의 현안 쟁점에 대한 경제적 검토

정재호 ( Chung Jai-ho ),임소희 ( Lim So-hee ) 한국협상학회 2017 협상연구 Vol.20 No.1

미국 정부는 최근에 증가하고 있는 대한 무역적자를 염두에 두고 2012년 3월부터 발효된 한미 FTA의 재협상 가능성을 제기하였다. 본 논문은 이러한 미국의 한미 FTA 재협상 가능성 제기를 배경으로, 향후 발생할 수 있는 재협상 과정에서 먼저 재협상 문제를 제기한 당사자인 미국의 입장을 전략적으로 살펴보기 위하여 한미 FTA 이후 변화하고 있는 한미 양국간 무역수지를 미국의 입장에서 분석한다. 한미 FTA의 발효 이후 미국의 대한 총 상품 수지는 적자폭이 확대되었으나 미국이 비교우위를 가지고 있는 농수산업 및 첨단 산업의 경우 미국이 흑자를 기록하였고 서비스 수지는 꾸준한 흑자를 기록하였다. 또한 최종재 수출로 인한 미국의 부가가치 창출 정도가 한국보다 월등히 높음이 드러났다. Facing the current account deficit against South Korea, the government of United States claims the necessity of renegotiation or expiration of the KORUS FTA. To understand strategic position of US government in the possible renegotiation of KORUS FTA in near future, this study intends to provide explanation about the real economic impact of the Korea-US Free Trade Agreement (KORUS FTA) on the US trade balance. From the investigation of trade balance of each cluster of the products, we propose that current account deficit of US against South Korea does not necessarily imply the negative impact of KORUS FTA on the US economy. We also emphasize that US has superiority over Korea in creating value added from exporting of final goods.

This paper examines the potential effect of corporate international diversification on cost of equity capital for Korean firms. Corporate international diversification is defined as a firm`s strategy by which a firm conducts its businesses in multiple countries at the same time. In an ex-ante sense, more internationally diversified firms may decrease their cost of equity capital through reduced volatility of future cash flows and/or reducing more effectively unsystematic risks by investing into various countries. However, it is also possible that cost of equity capital of more internationally diversified firms may increase since they will be exposed to greater foreign exchange translation risks or political risks of other countries and/or since they may have higher agency costs for their controls of managers located out of their home country of domicile. By using 755 Korean firm/year observations between 2000 and 2005, we find that the level of corporate international diversification, which is measured by the relative ratio of overseas sales (or assets) to total sales (or assets), is positively associated with ex-ante cost of equity capital, which is proxied for by implied cost of equity capital derived from equity valuation model, even after well-known risk proxies are controlled for. Thus, we conclude that more internationally diversified Korean firms increase their cost of equity capital. This is the first study to examine the effect of corporate international diversification on cost of equity capital for Korean firms. We believe that our empirical evidence may shed some lights on our understanding of the potential effect of corporate international diversification on various aspects of firms.

웁살라 모형의 국제화 단계에 비추어 본 LG전자의 국제화 역사에 관한 연구

한국의 대표적인 수출 산업인 전기전자 산업 중 LG전자는 한국 최초의 전자회사이자 가장 앞서 해외 시장 수출과 국제화에 나서 세계적인 다국적기업으로 성장한 기업이다. 본 연구는 개발도상국의 기술과 자본이 부족한 중소기업으로 시작하여 높은 수준의 국제화를 달성한 LG전자의 사례를 단계적 국제화 이론인 ‘웁살라 모형(Uppsala Model)’에 기초하여 각 단계별 주요 전략과 핵심요소를 분석하고자 한다. 웁살라 모형이 제시하는 바와 같이 LG전자는 누적되어가는 경험적 지식을 바탕으로 점진적으로 국제화 수준을 높여갔다. 국제화의 첫 단계는 대리상을 통한 산발적 수출이었으며 두 번째 국제화 단계인 해외 판매법인 설립을 통한 규칙적이고 체계적인 수출 및 브랜드 구축 단계로 발전했다. 마지막으로 LG전자는 선진국의 신보호무역주의 조류의 극복과 글로벌 전략 완성을 위해 투자 규모와 요구 수준이 가장 높은 해외 생산법인을 통한 현지화 단계로 점진적으로 이전해 갔다. 각 단계에서 경험한 주요 도전요인과 LG전자가 이루어낸 성과는 한국 제조기업의 국제화에 대한 시사점과 기술과 자본이 부족한 개발도상국 기업들의 국제화 성공 모형을 제안한다. Electronics industry has been Korea’s leading exporting industries which experienced the first internationalization stage of Korean firms. LG Electronics is the first electronics firm in Korea that succeeded in foreign market penetration and internationalization, and became a world leading MNC. This study adopts Uppsala model of internationalization to analyze how LG Electronics transform itself from small and medium sized firm without competitive products and international experience to successful MNC. Uppsala model proposes that firms gradually intensify their activities in foreign markets, as firms can accumulate market knowledge to utilize such knowledge in increasing market commitment. First, the firm started to export in sporadic manner by using export agents. Second, accumulated knowledge and experience allowed LG Electronics to set sup its own foreign sales subsidiaries. Establishment of sales subsidiaries allows for regular and planned exporting activities. Lastly, LG Electronics established foreign manufacturing subsidiaries which need a large resource commitment. The sequential foreign market entry is especially followed by emerging market firms, since they lack competitive resources or knowledge, and LG Electronics’ internationalization history displays such internationalization process.

PGE1의 국소 도포가 백서의 임의형 피부판 및 혈압에 미치는 영향

Salvaging the compromised random pattern flap remains a challenge for plastic surgeons. For the purpose of augmenting blood flow, vasodilators have previously been used in an attempt to improve survival of ischemic skin flaps. One such agent, prostaglandin, a vascular smooth muscle relaxant and a inhibitor of platelet aggregation, has been widely used clinically to improve peripheral circulation. But when used intraarterially of intravenously, systemic side effects such as hypotension, nausea, dizziness, and diarrhea were frequent. This study was designed to investigate the survival of random skin flaps and blood pressure when prostaglandin E1 was applied topically. Sprague-Dawley rats (N=30) were divided into control group (N=10); hydrogen base ointemnt only aplied, intraperitoneal group (N=10); PGE1 1㎍/kg injected intraperitoneally, and topical group (N=10); PGE1 powder mixed in hydrogen-base ointment (1㎍/kg) applied topically (N=10). A classic Mcfarlane random type flap (10 ×4cm) was elevated on the dorsum of rats. Blood pressure was measured by indirect tail plethsmography every 5 minutes until normalization. After seven days each animal was evaluated for percentage area of flap survival and the following results were obtained; 1. Flap survival areas in the PGE1 intraperitoneal injected group (65.2%) and topically applied group (82.9%) were greater than the control group (55.5%). 2. Blood pressure decrease of an average of 7mmHg was seen in the PGE1 intraperitonel injected grop. 3. No blood pressure change was in the control and topical appled groups. These experimental data suggested that topical application of PGE1 increased random flap survival without lowering blood pressure and thus may offer the same benefit of increasing area of survival in the compromised random flap but without the common side effects.

Zygomatic arch fracture is one of the most commonly seen facial bone fractures and there have been many methods of reduction designed so far. However, for a simple fracture, the Gillies temporal approach is most commonly used because of the easy reducibility, and also because the depressed fracture can be approached without a facial incision. The Gillies temporal approach starts in the temporal area, between the temporalis muscle and deep temporal fascia. We have developed a new route which starts in the postauricular hair margin area and then reaches to the periosteum of the temporal bone. An elevator is then inserted to penetrate the periosteum and subperiosteal dissection is performed toward the zygomatic process of the temporal bone. At the origin of the zygomatic process, the route of dissection changes to the posterior aspect of the zygomatic arch using a curved palate elevator or the authors` modified Langenbeck elevator. This method of approach has been used in 6 cases of zygomatic arch fracture with good results and we report this method along with written reports.
