시장지배력(市場支配力) 개념은 독점금지사건(獨店禁止事件)을 경제적(經濟的)으로 분석(分析)하여 위법성(違法性)을 판단하는 과정에서 핵심적인 역할을 한다. 시장지배력(市場支配力)은 어떤 시장구조(市場構造)가 경쟁제한(競爭制限)으로 인해 소비자(消費者)의 후생(厚生)을 침해할 수 있는 잠재력(潛在力)을 갖는지에 대해서 명확하게 답변해 준다. 시장지배력(市場支配力) 중심의 경쟁정책체계(競爭政策體系)는 시장지배력(市場支配力)을 보유하는 기업의 경쟁제한행위(競爭制限行爲)는 상대적으로 큰 후생감소효과(厚生減少效果)를 초래한다는 관점에서, 그들의 경쟁제한행위(競爭制限行爲)를 집중적으로 규제한다. 이 체계는 소비자후생(消費者厚生)과 효율(效率)을 높일 뿐만 아니라 중소생산자(中小生産者)를 보호(保護)하고 지배력분산(支配力分散)을 도모할 수 있다. 또한 이 체계에서는 규제범위(規制範圍)가 간명(簡明)해지기 때문에, 정책당국(政策當局)이 그것을 쉽게 관리(管理)할 수 있다. 이러한 관리가능성(管理可能性)의 향상은 행정력(行政力)의 낭비를 막음으로써 기업활동(企業活動)의 자유(自由)를 확대(擴大)하는 데에도 도움이 될 것이다.

This study briefly examines the regulation of market-dominating enterprises in terms of market definition, judgement about market dominance, judgement about abuse of market-dominant position, and types of abuse of market-dominant position. This study explores Korea Fair Trade Commission's judgemental cases regarding the prohibition of abuse of market-dominant positions under 'Korea Monopoly Regulation and Fair Trade Act' and focuses on 21 cases related with Korean media industry. Based on this case analysis and literature review, this study derives major issues, problems, and possible alternatives in the regulation of market-dominating enterprises in media markets. And this study suggests implications about monopoly regulation and fair competition policy of Korean media industry.

This study investigates the dominant degree of product design factors through the process of change of design factors. The previous research suggested a concrete measurement method of dominant designs, but it did not investigate empirically the degree of dominance due to the limited data for changes of designs. In this research, thus, after collecting design data of mobile phones and we measured the dominance and structure change of the designs by year. The analyses showed the following two things. First, in design factors of mobile phone the dominance on the body form and the edge grows more and both of them as dominant design factors tend to converge into the rectangular body form and the round edge, respectively. Second, the dominance on other design factors(e.g. the button type, the open type, whether or not to have digital multimedia broadcasting(DMB) and video telephony functions, the combination of colors and the body color) increases and decreases; and hence, design levels tend to diverge. In conclusion, the measurement of dominance on product design factors contributes to marketing managers and designers who are required to establish a strategy for products under the rapidly changing circumstances of market. This research aims to provide those managers and designers with a guide line for a successful development of new product to prepare for the dominant design from this empirical study.

This paper examines the effect of the market power of firms in the product market on job creation, job destruction and net job growth. It uses the reconstructed establishment data in the Korean Annual Mining and Manufacturing Survey between 1982 and 2002. This paper shows that job creation has continuously declined since the late 1980s and the decline is common for both market-dominant and competitive firms. The effect of market dominance on job creation is negative, controlling the firm-characteristics variables such as firm size and firm age.

지난 6월 6일부터 9일까지 프랑스 파리에서 열린 OECD 경쟁정책위원회에서는 단독기업의 행위인 시장지배적 사업자의 지위 남용에 대한 round table 회의가 열렸다. 라운드 테이블(round table) 회의는 6월 7일 8일 두 차례에 걸쳐 개최되었는데, 7일에는 시장지배력의 정의 및 입증에 대해서, 그리고 8일에는 시장지배력의 남용행위에 대한 제재수단에 대해서는 논의가 있었다. 공정거래위원회에서 시장지배적 지위 남용을 담당하고 있는 필자는 동 회의에 참석하여 우리의 경험을 애기하고 다른 나라의 경험을 들을 수 있는 유익한 기회를 가졌었다. 여기서는 당시에 논의되었던 내용들을 정리하고 정책적 시사점을 도출하여 보고자 한다.

As the industrial structure of the mobile telecommunications market is transforming into the ICT ecosystem centered on smartphones, the regulatory system conforming to the new ICT environment has become the main subject of discussion in key developed countries. The EU segmented the mobile phone service into wholesale and retail. Simultaneously, the EU appraised mobile telecommunication carriers' market domination in segmented markets to continuously improve the scheme to promote competition in the telecommunications market. In Korea, also, there is discussion about adopting the EU scheme to segment the mobile phone market definition more finely and taking measures to appraise the market domination in accordance with object appraisal criteria. As such, this study analyzes whether the current criteria for appraising the wholesale termination rate market domination under the ICT's domestic mobile telecommunication ecosystem is adequate and presents the rational improvement measures reflecting the theoretically suggested evaluation factors.

This paper establishes the empirical model based on Hall's(1990) and Basu' s(1996) models, estimates the five types of productivity in the medical service industry over the period 1975:1-2010:4, and analyzes the cyclicality of measured productivities and their correlations with the industrial real wage. The empirical results are summarized as the followings. First, there proved to be substantial market power in pricing and returns to scale in production for the medical service industry. Second, the three types of productivity among 5 types showed to be procyclical. Third, the average labor productivity, the original Solow residual, and the cost-based Solow residual are expected to provide reasonable indexes in analyzing the relationship between productivity and real wage.

전력 산업이 자유화되고 경쟁을 통해 효율성을 증가시키려는 시도가 이루어지고 있다. 전력이 시장을 통해 거래되는 형태가 완전경쟁에 가까울수록 사회후생이 증가한다는 것이 알려져 있다. 하지만 발전 회사가 시장지배력을 행사하여 가격을 경쟁가격에서 벗어나게 함으로서 자신의 이익을 취하려 할 때 시장의 효율성은 감소하게 된다. 시장 지배력을 감소시키는 한 수단으로서 발전회사에 선도계약을 부과하는 방법이 있다. 발전 회사에 선도계약을 부과하는 방법을 사용할 때 어떤 회사를 선도계약 부과대상으로 삼을 것 인지와 계통의 송전제약 통에 대한 고려가 필요하다. 이에 대한 연구가 2모선 계통에 대해 게임이론의 혼합균형 개념을 통해 부분적으로 이루어져 있다. 본 논문에서는 3모선 계통에서 선도계약의 영향을 분석하고자 한다. 본 논문의 해석 결과에 의하면 3모선 계통에서도 선도계약은 상황에 따라 시장지배력의 감소 혹은 증가를 모두 불러올 수 있으며 기대사회후생에 부정적 영향 뿐 아니라 부정적 영향 역시 줄 수 있다.

Transmission congestion is one of the key factors to local market power in competitive electricity markets. Financial transmission rights provide the financia] protection to their holders by paying back the congestion rent. A variety researches have shown that the existing trading mechanisms on transmission right can exacerbate market power. This paper proposes an alternative methodology in mitigating the local market power using the Contingent Transmission Rights on the locational marginal pricing scheme. The proposed methodology was demonstrated with the Optimal Power Flow.
