The purpose of this paper is to show the effect of information sharing strategy on the supply chain performances. While traditional information sharing models assumed centralized stock information, recent supply chain practices often implement fully shared stock information, where real-time stock information is accessible on retailers. When retailers are competing with each other, this fully shared stock information may incur retailers' strategic order behaviors. Thus, this paper analyzes a simple two-level supply chain consisting of one warehouse and two identical competing retailers where the real time stock information is fully shared. The warehouse uses the traditional echelon stock policy. Under this environment the retailers' reorder decisions are derived using the order risk concept and the retailer competition mechanism is analyzed. Computational results show that the supply chain performace degradation in the fully shared stock information is quite significant, implying the importance of designing information sharing strategies in the supply chain design phase.

As Asia becomes increasingly integrated economically, opportunity particularly in managing financial flows, as bases to coordinate regional production networks, and as staging points for the penetration of new markets. The paper argues for a path-dependent logic to understanding the efforts of the Singapore State in hosting hub functions. As a city-state without a national economic hinterland, Singapore's response to increasing business costs and regional competition has been to create a set of policies designed to encourage multinational companies to keep administrative control functions in Singapore while moving the more labour and land intensive production functions to nearby Malaysia and Indonesia. An understanding of the competition among cities in the Asia Pacific for hub functions must also take into account corporate strategy within particular industry dynamics. The second half of the paper provides a number of case studies to show this interplay between corporate strategy, industry dynamic and government policy.

Coping with the rapid change of competition in retail industry, retail firms have dreamed various differentiation strategy to obtain their added value and their life. And they have considered CRM strategy that can differentiate with other retail firms in order to develop some new differentiation factors. So we searched new factors that is best for "T store" and found CRM strategy such as the optimization for product portfolio considering private-brand products and the optimization for product display for customer demands. This study is meaningful in that it has suggested a new CRM strategy model, which can manage new various differentiation factors of a retail firms considering its core competence. We verified and altered retail firm's business model using system dynamics. By simulation results, CRM strategy need long time to obtain visible and satisfactory performance of "T store".

Nash Equilibrium (NE) is essential to investigate a participant's bidding strategy in a competitive electricity market. The transmission line constraints make it difficult to compute the NE due to causing a mixed strategy NE instead of a pure strategy NE. Computing a mixed strategy is more complicated in a multi-player game. The competition among multi-participants is modeled by a two-level hierarchical optimization problem. A mathematical programming approach is widely used in finding this equilibrium. However, there are difficulties to solving a mixed strategy NE. This paper presents two propositions to add heuristics to the mathematical programming method. The propositions are based on empirical studies on mixed strategies in numerous sample systems. Based on the propositions a new formulation is provided with a set of linear and nonlinear equations, and an algorithm is suggested for using the prepositions and the newly-formulated equations.

본 연구는 우리나라 제조업에 있어서 산업별 시장개방의 차이가 기업의 고용전략과 노사관계에 어떤 영향을 미치는지를 실증분석을 통하여 살펴본다. 우선 기업의 고용전략 면을 살펴보면 시장개방이 확대될 때 혁신전략 또는 노동비용절약적인 전략 중 어느 특정 전략을 선호하는 것으로는 나타나지 않는데 이는 시장개방이 임금이나 고용에 매우 미약한 영향을 미쳐왔다는 기존의 외국 연구와도 연관성을 갖는다. 또한 세계화 등으로 시장개방이 확대되면 기업이 노동비용절약적인 정책을 보다 더 확대할 것이라는 일반적 우려가 적어도 우리나라 제조업 부문에서는 실증적으로 증명되지 않는다는 것을 보여준다. 시장개방과 노사관계에 관한 연구 결과는 좀더 흥미로운데, 시장개방도가 높은 산업에 속하는 기업일수록 협력적 노사관계를 가질 가능성이 높게 나타나고 있다. 또한 시장개방이 확대될 때 노동조합이 존재하는 경우에 협력적인 노사관계가 보다 더 강해지는 것으로 나타나는데 이는 '대외경쟁'라는 공동의 적이 생기면 노동조합이 있는 경우 노사가 더 합심해서 타계하려고 노력한다는 것을 시사한다.

Lately there are many approaches for decreasing the retail prices for mobile telecommunication in response to higher demand of the consumer welfare. Related on this perspective, there have been many disputes how the MTR (mobile termination rate)s from the whole market has influences on the consumer prices at the retail market. Therefore, we need a timely review about the possibility of the reduction of retail prices with MTR policies. The purpose of this paper is to study the relationship between MTR and retail prices. For this purpose, we can identify three kinds of arguments by reviewing the previous literatures. We empirically analyze the relationship with latest European data and Korean annual data. Furthermore, we also examine whether the relationship would depend on the competition structure. The results imply that decreasing MTR would result in reduction of the retail prices but the effect would be enhanced by improvement of market concentration.

The purpose of this study is to examine the elements that satisfy customers in order for restaurants to survive in competition, and to examine effective positioning strategies. Since the designation of Haeundae in Busan as a Special Tourism Zone, diverse food service markets have been established and various marketing activities are anticipated accordingly. The results of this study can be summarized as follows: First, after the examination of the competitive relationships among restaurants, based on the image similarity data, it was found that Bennigan's, Outback Steakhouse, and T.G.I. Friday's are in close proximity with one another. Hence the fierce competition between them. Secondly, as a result of PC-MDS PROFIT analysis, a positioning map was drawn with image similarity measurement of the restaurants and scores 9 evaluation categories for each brand name as follows: food taste, food price, service, access convenience, hygienic condition and cleaning, atmosphere, various events, circumferential environment, and public image. Thirdly, as a result of MDPREFMAP analysis based on the customer preference, data from the restaurant brand names, an ideal location of a restaurant preferred by customers and the position of restaurant brand names were indicated at the same time.
