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.

Recently, the Korea's economy concerns the second money crisis because of the rapid increase of the exchange rate. The Korea's economy which is very dependent on the foreign trade is more sensitive to the change of exchange rates. There are many literatures which analyze the effects of variations of the exchange rates on the secondary and tertiary industries such as the manufacturing industry and IT(Information Technology). But there have been no studies which try to figure out the effects of variations of exchange rate on the primary industries, especially, fisheries' industry. Therefore this paper tries to analyze the effect of price competition structure and the change of exchange rate on foreign fisheries exporting prices in Korea's fisheries import market. This study utilizes OLS(Ordinary Least Squares Analysis) for the analysis in the market of frozen yellow corvina, hairtail, angler fish which are major fisheries importable in Korea. The results show that the exporting country which has the highest market share is more sensitive to the change of the exchange rates itself than that of the other exporting countries' price when it starts to set up its exporting price. And the exporting countries which have low market share are more sensitive to the change of price which country has the highest market share than that of price whose countries have low market share and those of their exchange rate. Also we can find out that the countries which have similar market share try to set up price-setting strategy in the opposite direction. In other words, one country tries to bid up its price, other countries response to rival country by lowering their prices. In the consideration of the fact that most exporting countries aren't affected by Korea's fisheries' prices, the exporting countries in Korea's fisheries import market are more sensitive to the prices of other exporting countries than that of Korea's. This result indicates that the price leader-follower model could be applicable to the Korea's fisheries import market.

빙그레는 국내 최초로 떠먹는 요구르트인 요플레를 출시한 후 지금까지 요구르트시장에서 요플레의 막강한 브랜드 파워와 함께 확고한 시장지위를 차지하고 있다. 본 연구에서는 더욱 치열해지고 있는 요구르트시장의 경쟁 속에서 빙그레가 시장선도자(떠먹는 요구르트시장)로서 또한 시장후발주자(드링킹 요구르트시장)로서 어떻게 시장을 개척하고 대응해왔는지를 분석하였다. 연구 결과, 빙그레 요플레는 기존의 경쟁논리에 얽매이지 않고 새로운 가치를 제공하면서 시장의 경쟁패러다임을 변화시키기 위해 시장을 선도하는 차별적인 신제품 마케팅전략을 실시하고 있음을 알 수 있었다. 앞으로도 빙그레 요플레는 장기적으로 요플레의 브랜드 자산을 관리하기 위한 보다 정교한 마케팅전략적 관리와 함께 시장을 이끌어가기 위한 지속적인 마케팅 노력이 병행되어야 할 것이다.

Purpose - Our Research is a study on the competition structure between retailers in traditional markets. Specifically, this study examined the effects of SSM, commodity supply store, Hanaro mart, food mart and other mart in traditional markets on retail stores of small businesses. The purpose of this study is to provide a solution to the market encroachment of large retailers in traditional markets. Research design, data, and methodology - This study is based on the data of 'Market Survey of Traditional Market·Shopping Mall and Store Management in 2016' and 'Current status of SSM(Super SuperMarket), commodity supply store, Hanaro mart, food mart and other mart in the traditional market in 2017' conducted by Small Enterprise and Market Service. In this study, a multiple regression equation was constructed using the number of SSM, commodity supply store, Hanaro mart, food mart and other mart as an independent variable and sales, number of customers as a dependent variable for analysis. Results - The increase of SSM and commodity supply stores in the traditional market affects the sales decrease of the surrounding small merchants in the traditional market. This means that the SSM and commodity supply stores can lead to the decline of the traditional market. However, it has been found that the penetration of these companies in traditional markets does not affect the number of visitors. Second, Hanaro mart's entry into the traditional market has a negative impact on the sales and visitor numbers of the surrounding small-scale merchants. The increase in the number of food mart has a significant effect on the sales and the number of visitors to the small stores. The results of this study indicate that the food mart can contribute to the revitalization of traditional markets. Lastly, other mart with more than medium size were found to affect the sales of small stores, the number of visitors. Conclusions - We examines the competitive structure among retailers in traditional markets. The penetration of large retailers in traditional markets has a negative impact on traditional markets, particularly Hanaro mart has a greater impact than SSM. We provide practical and theoretical implications for the retail competition structure in traditional markets.

This study aims to investigate the effects of market commonality and resource similarity on price competition and the recursive consequences in the Korean lodging market. Price comparison among hotels in the same geographic market has been facilitated through the development of information technology, rendering little search cost of consumers. While the literature implies the heterogeneous price attack and response among hotels, a limited number of empirical researches focus on the asymmetric and recursive pattern in the competitive dynamics. This study empirically examines the price interactions in the Korean lodging market based on the theoretical framework of competitive price interactions and countervailing power. Demonstrating superiority to the spatial lag model and the ordinary least squares in the estimation, the results from spatial error model suggest that the hotels with longer operational history pose an asymmetric impact on the price of the newer hotels. The asymmetry is also found in chain hotels over the independent, further implying the possibility of predatory pricing. The findings of this study provide the evidence of a hierarchical structure in the price competition, with different countervailing power by the resources of the hotels. Theoretical and managerial implications are discussed, with suggestions for future study.

MVNO제도는 선발사업자인 MNO가 보유한 필수설비를 후발사업자가 임대하여 무선통신서비스를 제공하는 이동통신시장의 서비스기반 경쟁정책이다. 서비스기반 경쟁정책은 신규사업자에게 설비를 제공하여 시장 내 경쟁을 촉진시키는 장점과 더불어 기존사업자의 투자의욕을 저하시켜 시장성장을 더디게 하는 단점도 동시에 지니고 있다. 경쟁정책의 도입과 적용이 시장구조에 미치는 영향을 고려해볼 때 도입 이전단계에서 면밀한 검토가 이루어져야 한다. 따라서 본 연구에서는 이론모형 설정을 통해 MVNO가 시장효율성에 미치는 파급효과와 효과적인 MVNO 실시방안에 대해 객관적인 분석을 시도해보고자 한다. 이를 위해 Laffont, Rey and Tirole(1998)과 Armstrong(1998)의 모형을 기초로 MVNO의 특성을 반영한 모형을 설정하여 MVNO 제도 도입 후 상호접속료, 시장가격, 수량, 일방접속료 등에 대한 시사점을 도출하였다. 연구결과 MVNO 제도가 도입될 경우 MNO간 담합 유인이 완화되어 가격이 낮아지고 수량이 증가하는 등 정태적 효율성이 향상되는 것으로 나타났다. 구체적인 MVNO의 실행과 관련하여 한 사업자만 MVNO를 실시하는 경우, 두 사업자 모두가 실시하는 경우, MNO와 MVNO를 구조적으로 분리하는 경우의 시장구조를 살펴본 결과 가격과 수량 측면에서 모든 사업자가 MVNO를 실시하는 경우가 가장 효율적인 것으로 나타났다.

Recently, Korea's electric industry has experienced substantial changes in its structure and function including the introduction of competition in the generation sector. Korea is in the early stages of market competition where the market price is determined by generation costs. In the future, the market Price will be determined by generators'bids. Therefore, the generators'profit is determined by market pool price, the prospects of pool price are very important for new capacity investment decision made by generators and IPPS. This study analyzes hourly marginal costs and LOLP considering basic generation mix and characteristics develops the relationship of pool price and Profit by generation-type using the change in reserve margin, and proposes basic direction for profits variation and supply-demand analysis in the electricity market in future.
