경쟁법은 혁신을 촉진할 수 있고, 소비자후생을 증대한다. 지적재산권의 제한적인 배타성도 혁신을 촉진할 수 있고, 소비자에게 이롭다. 경쟁법과 지적재산권법의 상호관계는 상호조화가 필요한 보완관계로 파악하여야 한다. 우리 경제가 신경제화되고, 첨단기술 산업의 발전과 함께 성장하고, 지적재산권의 강력한 보호의 방향으로 나아가는 것을 전제할 때, 경쟁법은 그 변화에 대응하여 시장에서 발생하는 지적재산권에 관련한 공정거래법 위반사건에 대한 처리기준을 준비하여야 할 것이다.

The government has the responsibility to prevent abuses of monopoly and promote competition in order to maximize consumer welfare. The government should address the asymmetry in the information as much as possible and ensure consumer choice. The subsidy seems to reduce the burden on the consumer service charges and handset prices but it actually distorts the market through price discrimination. The government caused the principal-agent problem by neglecting their appropriate role to prevent distortion of the mobile telecom market. The money used as subsidy is part of excess profit and could be transferred to down the price of mobile phone and charges and it would become a benefit to consumers. Separate announcement of subsidies by Mobile Communications Terminal Distribution Structure Improvement Act is a little developed policy but it was not actually realized. The market price close to that from perfect competition structure is plausible, ultimately.

The government has the duty to prevent abuses of monopoly and promote competition in order to maximize consumer welfare. In order to promote competition we have to address the asymmetry in the information as possible and to ensure consumer choice. The subsidy seems to reduce the burden on the consumer service charges and handset prices but it virtually distort the market through price discrimination. The government caused the principal-agent problem by avoiding their appropriate role to prevent distortion of the mobile telecom market. The money used as subsidy could be transferred to down the price of cell phone and charges and it would be a benefit to consumers. Separate notice of subsidies by Mobile Communications Terminal Distribution Structure Improvement Act is a developed policy but it was too late. It, the market price close to that from perfect competition structure, is plausible, ultimately.

In order to incorporate substitution effects between different transport modes in optimal road Pricing, relating economic theories and models have been reviewed. It includes unconstrained optimization problem of maximizing separable and non-separable social net benefit functions of different substitutable urban transport modes. In doing that, the problem and limitations such as path-independent conditions with the asymmetric Jacobian of the objective function have been reviewed. Consequently, a plausible way of deriving optimal road price under interdependent market conditions has been suggested so that the idea can help identifying desirable and acceptable urban transport policy alternatives in a more comprehensive way.

As part of the ongoing global process of airlines forming strategic alliances, Korean Air has become a member of the SkyTeam Alliance, while Asiana has joined the Star Alliance. However, as something akin to the Anti-Trust Immunity(ATI) initiative has not been ratified domestically, these two airlines have seen their roles within these strategic alliances significantly reduced. In keeping with its domestic airline liberalization policy the U.S. government has instituted a mechanism through which foreign airlines that join such strategic alliances with their American counterparts can be exempt from the U.S. antimonopoly law. As a result, U.S. airlines have been able to forge wide ranging cooperative relations with foreign airlines, and thus increased their competitiveness within the air transport industry. This study analyzes the applicability of this Anti-Trust Immunity initiative to the domestic environment.

Terms of trade shocks have been considered one of the main driving forces causing business cycle fluctuations in small open economies. Despite their importance in business cycles of small open economies, it is hard to find a serious study in existing literature investigating their implications on monetary policy under a small open economy. Considering it, this paper studies what form of monetary policy rule is the most adequate for a small open economy where terms of trade shocks are dominant factors in generating its business cycle fluctuations. For this purpose, various implementable monetary policy rules frequently analyzed in existing literature are compared in terms of social welfare levels which they can provide for the economy respectively. Main results of this paper can be summarized as follows. First, for a small open economy where terms of trade shocks are main driving forces of its business cycle fluctuations, the nontradable goods price inflation targeting can provide higher level of social welfare than other traditional monetary policy rules such as the CPI inflation targeting or the fixed exchange rate regime. Second, the social welfare improvement of the non-tradable goods price inflation targeting is more apparent when export goods price shocks are more important than import goods price shocks.

This paper finds that the ultimate source of problems facing Korean mobile telecommunications such as excessive subsidies of handsets, waste of resources, and a vicious circle of expensive handsets and high prices for services, is bundling of handset and subscription. The analysis suggests that bundling causes consumers to confuse about prices of handsets and services, and firms focus on handset subsidy competition rather than on upgrading service qualities and lowering prices due to anti-competitive effects of bundling. Because most of the cost of bundling is passed on to consumers, the welfare of consumers decline. In particular, equality among consumers worsens due to price discriminations. To resolve these problems, unbundling of handset and subscription is a necessity. Mixed bundling allowing separate selling of handsets under bundling does not seem to work as a cure because bundling tends to be a dominant strategy. The best regulatory policy is a complete separation of handset and subscription.

America is traditionally friendly to South Korea. Last year in 2008, U.S. exports to South Korea totaled $32.4 billion. The U.S. and Korean must reciprocate economic exchange. The purpose of this study to measure the re-purchase intentions and product satisfaction in America image. The major result of article can be summarized as follows. The factors of this article have been divided into 'society safety', 'industrialization level', 'economic image', 'political image', 'cultural image', and 'the character of a nation'. In the empirical result of the article, the goods satisfaction for America country image would be shown in the results. The first, 'society safety', 'industrialization level', 'the character of a nation' are significantly positive statistically to goods satisfaction. The second, 'economic image', 'political image', 'cultural image' are not as significantly positive statistically speaking.

본(本) 연구(硏究)에서는 가계(家計)가 소비지출시 어느 정도 유동성제약(流動性制約)(liquidity constraint)하에 처해 있는가를 분석하기 위하여 이론적인 모형(模型) 제시와 함께 한국(韓國) 일본(日本) 미국(美國)을 대상으로 실증분석(實證分析)을 시도하였다. 3개국 공히 내구재(耐久財) 소비지출시 비내구재(非耐久財) 소비에 비해 상대적으로 유동성제약 현상이 더 심한 것으로 추정되었다. 특히 우리나라의 소비자들은 내구재와 비내구재 등 모든 형태별 소비지출에 있어서 일본(日本)과 미국(美國)에 비해 더 심한 유동성제약하에 처해 왔던 것으로 나타났다. 1980년대에 들어서는 소비자금융시장에서의 유동성제약(流動性制約)이 점차 완화(緩和)되어 온 것으로 나타났으나, 여전히 일본과 미국의 수준을 크게 상회(上廻)하였다. 이러한 추정결과들은 장기간에 걸친 생산자(生産者) 중심의 금융제도 및 관행 등으로 인해 우리나라의 소비자금융시장(消費者金融市場)이 선진국에 비해 낙후(落後)되어 있음을 반영한다. 위의 분석결과는 향후 할부금융제도(割賦金融制度) 도입 등 소비자금융 규제 완화가 본격화되면 유동성제약(流動性制約)이 완화되어 가계의 차입(借入)과 저축(貯蓄)을 통한 소비의 평탄화(平坦化)(smoothing)가 가능해짐으로써 소비자의 후생(厚生)이 증대되고 경기변동(景氣變動)의 진폭이 축소될 것임을 시사한다. 또한 소비자금융의 활성화는 기존의 유동성제약하에 처해 있었던 가계들의 소비를 촉진시켜 단기적으로는 경제 전체의 저축률(貯蓄率) 하락요인으로 작용할 가능성도 있을 것이다.
