민영화 이후의 경쟁정책에 있어서 공기업 민영화의 궁극적인 목표가 시장기능의 활성화를 통한 효율성 제고에 있음을 깊이 인식하여 민영화 과정에서 관련시장을 경쟁적인 시장구조로 전환하고 시장원리가 제대로 작동할 수 있는 여건을 마련하는데 더 큰 관심을 가져야 할 것이다. 공기업이 독점적 지위를 그대로 유지한 채 민영화한다면 이는 공적 독점으로부터 사적 독점으로의 단순한 전환을 의미할 뿐이며, 공적 규제의 악화로 사적 독점의 폐해가 보다 심각해질 우려도 있기 때문이다.

This paper starts with a model of monopolistic competition and endogenous growth, and it adds pollution as an input to production. Then I adopt environmental quality as a renewable resource used in production. I show that increasing returns due to specialization of clean activities as inputs can help lead to sustainable growth with no harm to environmental quality. I also compare and evaluate alternative policy combinations (i.e. taxes +subsidies) that correct two distortions from pollution and monopolistic competition. Finally, I find that, if the productivity of environment in final good production is not sufficiently enough, the number of clean goods tends to increase with more environmental concerns.

경쟁제한을 제거해야 한다는 경쟁정책적 결론에 관해서는 이견이 있을 수 없다. 그리고 어느 경쟁개념의 관점에서나 인위적 시장진입장벽은 경쟁제한이다. 그래서 어떤 기업이건 최소한 경쟁압력을 받도록 유지시키고, 독점적 지위가 궁극적으로 제거될 수 있도록 전체 시장들의 개방유지가 합리적인 경쟁정책의 주요과제가 되어야 한다. 시장진입장벽은 국가에 의해서는 연유할 수 있으므로 효과적인 경쟁정책을 위해서는 국가와 관련된 경쟁제한도 경쟁의 예외영역이 아닌 한 제거하여야 한다. 과규제 되고 기존기업의 보호를 위해 폐쇄된 시장이 존재한다면, 개방이 추진되어야 하고, 국공영기업의 불필요한 독점의 제거를 통한 규제완화도 더욱 필요하다.

This paper measures market power in the Mongolian banking sector using bank level panel data for commercial banks over the period of 1999 - 2006. In the literature, studies on banking competition have largely focused on the banking sectors of developed economies. However, banking competition in developing countries such as Mongolia has been largely neglected. This paper is an attempt to fill this gap. We find that both the monopoly hypothesis and the perfect competition hypothesis are rejected and that the Mongolian banking sector is instead characterized by monopolistic competition. We thus find that the Mongolian banking sector is more competitive than market concentration measures may suggest. We infer that the entries of new banks have strengthened market competitiveness.

This paper analyzes internet access model between ISP, CP and end users where CP uses various technologies to provide direct access to ISP owning subscribers to consume its own contents in low cost and high quality. The level of access charge depends on the competitiveness of CP market. When CP market is perfect competitive, the level of access charge is identical to that of social optimum while when CP market is monopoly, the level of access charge is influenced by the sensitivity of the contents price to access charge for CP. The dead weight loss due to monopoly market in CP can be removed by the regulation of access charge. Socially optimal access charge in monopoly market of CP is lower than that in competitive market. This is because the regulator wants to set access price to lower level to reduce welfare loss from monopoly in CP market where CP determines the price to over marginal cost.

치열한 자본주의 아래의 기업활동은 경쟁의 연속이다. 현재 세계 50대 기업 중 50년 전에도 존재하였던 기업은 손꼽을 정도라고 하니 자본주의하의 경쟁이 얼마나 치열한 것인지 알 수 있다. 이에 기업은 서로간의 연합, 협정, 결합 등을 통해 경쟁을 회피하려는 동기를 가지게 된다. 그러나 시장경쟁이 줄어들면 자연히 시장에서의 독점적 지위를 보장받는 데만 집중하여 궁극적으로 시장에서 독과점의 위치를 차지하게 된다고 보는 시각도 존재하고 있다. 본 호에서는 기업결합의 페해를 막기 위해 법률상에서 기업결합이 어떻게 규제되고 있는지 살펴 본다.

세계적으로 전력사업이 정부의 보호와 규제라는 전통적인 특성과 독점적인 운영구조가 급격한 변화를 겪고 있다. 종래 전력, 가스, 수도, 통신 등과 같이 망으로 연결되는 산업은 자연독점이 인정되어 왔으나 통신사업으로부터 시작된 경쟁화의 바람은 전력사업에도 영향을 미쳐 세계각국의 전력사업체제가 변화되고 있다.

This paper formulates a monopolistic competition model by incorporating Leontief product function into Dixit and Stigliz model to analyze and compare the effects of two environmental policy instruments-fuel efficiency regulation and environmental tax-on a market which reflects characteristics of international vehicle market. As expected, both policy instruments raise equilibrium market prices. The effect of fuel efficiency regulation on firm output, the number of firms, and industry output, however, depends on three determinants-the increasing rate of the ratio of consumer expenditure to the income, the increasing rate of fixed cost, and the increasing rate of marginal cost. On the other hand, the imposition of the specific environmental tax reduces the firm output, but does not influence the number of firms. If these two instruments are assumed to lead to the same increasing rate of marginal costs, the environmental tax reduces the firm output as well as the industry output more than the fuel efficiency regulation. And it will induce more firms to exit the market than the fuel efficiency regulation if the increasing rate of the ratio of consumer expenditure to the income is larger than the increasing rate of fixed cost.

This paper uses the Panzar Rosse model to investigate the competitive conditions in the Korean life insurance companies over the period of 1999 2012. We break down the entire sample period into four distinctive groups and analyze the competitiveness of each period. The results indicate that for the pre-introduction of Bancassurance period, the H-statistic is -1.3984 and the life insurance market is found to be in monopoly or cartel. However, for the post-introduction of Bancassurance period, the H-statistic is 0.9107 and the life insurance market appears to be in monopolistic competition. The results from the introduction of retirement pension system are very similar to those of the introduction of Bancassurance. Overall, the findings indicate that the Korean life insurance market is in long-run equilibrium before the new system introduction, but make adjustments to the new equilibrium.
