We analyzed the effect of 6-month lagged number portability policy and introduction of common number among carriers on Korean mobile market. Our result shows that the policy change contributed to both the increase in number of mobile subscribers and decrease in dominant carrier's market share. We found that unified prefix among mobile operators is more effective than the lagged number portability policy. The carriers' profit, however, decreased a lot due to excessive marketing expenditure. We also estimated market shares of carriers up to year 2005 when full number portability policy is adopted. The results show that dominant carrier's monopolistic power will be recovered by the end of 2005 implying government's number policy itself cannot guarantee the effective competition in Korean mobile market.

This study derived implications regarding competition policy to establish a reasonable spectrum allocation draft of a 3.7 GHz spectrum band by indepth analysis of 5G spectrum auctions. The following general features were identified by examining auctions of three countries, including the United States, United Kingdom, and Denmark, were completed in 2021. First, securing the minimum bandwidth that is essential for service competition was guaranteed by applying the spectrum cap. Second, a continuous spectrum band was allocated to all mobile network operators. Third, certain requirements were implemented to encourage the expansion of 5G service coverage. The spectrum cap that was implemented in Korea during the most recent spectrum auction was ineffective regarding competition policy. Additionally, it is anticipated that the allocation of 3.7-4.0 GHz spectrum will considerably impact market competition because the continuity of spectrum band is different among mobile service operators. Therefore, it is time to discuss promoting the 5G service competition in Korea by revising related laws.

After the establishment of 'Staggers' Rail Legislation' in 1980, which established an atmosphere of free competition in rail freight transportation market, freight railway in America became larger and the proportion of freight railway in the market increased. In 2008, it took up 43% of the transportation market based on tonne/mile unit and the productivity of freight rail increased. On the other hand, in the case of Korea, the competing atmosphere is being set up under the influences of the renovation of the rail transportation industry in 2004. However, to make the rail transportation market more active and become more advanced, a lot of efforts are required to build a stronger foundation of free competition atmosphere. In this paper, we have deducted the political implications on the establishment of strengthened competition in Korean rail transportation industry from reviewing what kind of changes the rail transportation market in America went through and how it was developed. In this case, we have focused on the changes in industrial trend towards the restriction policy. Also influences of the deregulation policy after 1980 on the enhanced market efficiency were reviews.

This study examines the equilibrium investment on the pollution abatement when firms are facing Cournot competition in the output market while the pollution permit market is perfectly competitive. Unlike standard perfect competition scenario, the abatement investment delivers an indirect effect in which it reduces other firms' equilibrium output. Consequently, compared with the socially optimal level, overinvestment arises. I also overview the potential inefficiencies that imperfect market structure induces under the emission trading scheme, presenting policy implications.

This paper aims to develop methodology and indicators to review effective competition in Korean mobile telecommunication market. After examining strengths and weaknesses of other countries' experiences, we proposed several indicators for the assessment of competition. Developed from criteria such as transparency, regulation cost, policy objectives, proposed indicators comprise market structure, behaviour of sellers and consumers, and consumer benefits. These indicators are applied to the Korean mobile market. During the period 2001-2004, 'the competition assessment index' increased steadily, meaning the state of competition was aggravated during this period.

A Liner Conference can be defined as "a group of two or more vessel operating carriers which provide international liner services for the carriage of cargo on a particular route or routes within specific geographical limits and which has an agreement or arrangement within the framework of which they operate under uniform or common freight rates and any other agreed conditions with respect to the provisions of the liner services". This study reviews maritime transport policy regarding liner conference and the changes in the liner market over the decades. Liner shipping industry has long been protected from competition by block exemption. The repeal of the block exemption for liner conferences and the abolition of any special EC antitrust regime for the shipping industry marks an important step in European maritime competition policy. This article examines the origins and the rationale of the EC antitrust immunity granted so far th the shipping industry and explains the causes of this historic changes. The abolition of Regulation 4056/86 and of the EU commitment to the UN Code of Conduct marks an historical evolution in international maritime policy, which will have an influence far beyond the EU.

A teacher evaluation system is a hot issue of educational policy these days. Many teachers have opposed teacher evaluation system, but government and many parents have agreed teacher evaluation system. And some people agree teacher evaluation system, but some people disagree teacher evaluation system. The approvers of teacher evaluation system insist that teacher evaluation system can provide the quality of instruction, satisfaction of schooling, and nation's competition capacity. But opponents of teacher evaluation system insist that teacher evaluation system can provide dissatisfaction of teachers' job, excessive competition among teachers, and the failure of educational policy. So, comprehensive studies about teacher evaluation system are needed. The purpose of this study was to investigate that elementary and secondary teachers' recognition about teacher evaluation system. The tool of this study was used questionnaire which was made by researcher of this study. This study indicates as follows. Many teachers opposed teacher evaluation system, because of deficit of validity and reliability of teacher evaluation system. Also, many teachers indicated instruction ability as the most important evaluation standard of teacher evaluation system. And many teachers predicted the dissatisfaction of teachers' job and excessive competition among teachers as a result of teacher evaluation system.

This research began by recognizing the development of telecommunication skill in a short period of time as one achievement of launching the national research and development (R&D) project for the diversification of telephone service and for the solution of telephone holdup rate. Under this concern, this research is focusing on searching the influential elements on successful outcome by analyzing the case of Time Division Exchange R&D Project carried out by Korea. Those variables for analyzing the case is limited to 7 definite variables, which are "willingness of policy making organization", "participation of manufacturers and buyers", "support from research and development group", "economy of operating methods and selection of machinery", "rate of technology transfer", "support from Fixer", and "quality management". Summarizing the result of analysis, in order to bring about technological innovation, knowledge creation activity leading to upward efficiency through competition and cooperation making a harmony should be done in one mechanism. I.e., launching an innovative policy should be done in an arena of competition and cooperation, where stability of implementing system is achieved, the entity of "Fixer" is an adequate operator, and competition and cooperation is efficiently managed, among where agreement on purpose and professional opinions are reflected.

The rapid expansion of regionalism has resulted in the creation of blocs of the global economy, so that those countries not belonging to one or more blocs can be discriminated. The purpose of this paper is to examine the competition policy theoretically, international background with issues, and discussion trend of global enterprise. By doing them, this paper suggests the responsive plan, future prospects, and policy directions for the competition policy by distribution service. There is not a statistically significant relationship between international diversification strategy and firm performance. However, we observed some tendency that the larger the firm size, the higher the firm performance, assuming the degree of international diversification or multinationality to be constant. However, the export productivity increase after 1~2 years, and there exits a clear evidence that the innovation investment increases a firm's export competitiveness as time goes on.
