In this study, the methodology for measuring the structure of the Korean defense market and the competition status, and the characteristics of the Korean defense industry and the market are examined. To analyze the structure of the Korean defense market and the competition status, the market share, concentration ratio, and the Herfindal-Hirschman index are employed based on the annual sales of major Korean defense companies. On a basis of the result of the analysis, the suggestions for the Korean defense market to escape from the monopolistic market to be a competitive geographical market are presented. To present the suggestions, markets that have a similarity with the dense market are analyzed. The government's support policy, the selection of the companies led by the government, and the cost of the military are suggested for the defense market on a basis of analyzing similar markets. With the suggestions, when the government pursues the policies, the defense market sticking to principles and fairness is created and the efficiency of the companies operation is achieved, by enhancing the structure of the market fundamentally and the development of the policies in the industry's perspective.

Previous research on two-sided markets has, for the most part, concentrated on indirect network externalities between buyers and sellers. This paper considers direct competition effect among sellers and among buyers as well as indirect network externalities. We develop an analytic model of C2C e-marketplaces and examine whether a monopolistic incumbent could successfully deter new entry into its market. We find that the effect of the number of sellers or buyers on the price of goods depends on whether sellers have decided to sell the goods using an auction or fixed pricing rule and on the characteristics of the goods. We argue that when the effect of the number of sellers on the price of goods is significantly larger than that of buyers, there is a high possibility of entry. In particular, we show that entry becomes more difficult to deter as fixed-price format is adopted more frequently or the proportion of collectables is relatively low.

Into the telecommunications industry, which had been monopolistic, a few advanced countries introduced competition through 70's and 80's. And this trend is going on worldwide. The introduction of competition into the industry is made mainly in the long distance, international and enhanced market. This liberalisation results from the fundamental change of the cost function. Suggesting that the cost comprises of that of the facility sector and that of the operation sector there exists the economies of scale in the facility sector in general. The major ground for the monopolistic industrial structure in the past was the natural monopoly depending on the economies of scale. But the rapid advance of the technology by a large margin. This decrease has resulted in the change of the cost function. That is while there exists the economies of scale in the smaller production scale, the average cost increases beyond a certain scale. This means that the natural monopoly collapsed, and that the competitive structure is more efficient than the monopolistic structure. But, because there exists economies of scale in the smaller scale, the desirable number of players, which could result in efficient industry structure depends on the market size. Such correlation between technological level market size and the degree of regulation is found in the case of U.S.A., Japan and U.K., where deregulation policy of the telecommunications market has already been carried out. In U.S.A., which has the largest market and the highest technological level the degree of regulation is lowest. Also in the order of Japan and U.K. the regulation is severer. Japan and U.K. are likely to liberalize still more, as the technology advances and the market grows. This article is just the beginning of the research, and this hypothesis requires more detailed research.

Purpose - The purpose of this paper is to seek some alternative to overcome difficult shipping situations for overcapacity pursuing economy of scale, which is widely spread in world shipping. Research design, data, and methodology - The research method to be adopted is first to review evolution of larger ships in terms of theoretical overview, and shipping market is examined, and it is studied some problems and solutions in relation to larger ship as field research aspects. Results - Supply and demand of shipping market is flexible and unpredictable nature of market. Sometime fierce competition has spread out the market, and shipowner may deploy mega ship in terms of economy of scale, etc., to overcome the difficult market situations. Both carrier and shipper have their own positions in this matter concerned. However, it causes some problems in the market including port matters, etc. Therefore, it is asked to solve this problems of larger ship employed in the markets, throughout shipping alliances, etc. Conclusions - Over tonnage done by larger ship has caused some problems in the shipping markets, forming monopolistic market by small number of larger shipping companies, destroying oligopolistic nature of shipping business, therefore, the answer is strategic alliance to collaborate each other.

For the purpose of analyzing the influence of the recent environmental changes of container logistics system in container terminal, the simulation model of container logistics system on BCTOC is developed in this paper. The simulation model is accomplished by the AweSim simulation language, and the several data which have been used in simulation gained through spot research and basic statistic analysis using the first half of 1998 electronic data in BCTOC. The results of this study are as follows; (1) In the case of BCTOC, the decreasing of container volumes is observed during the first half of 1998 compare with that of 1997. (2) In the container handling service market, the monopolistic market system in the past rapidly diverts to the competition market system from now. (3) From the simulation results, the improving of container logistics system is observed. (4) Because of these results, BCTOC will come to strengthen customer service and competitive power through starting On-Dock service system and operating the team of customer management in the long term.

This study examines whether or not the South Korean major fishery product import markets; Frozen Pollock, Frozen Long Arm Octopus, and Frozen Hairtail are integrated. We are utilizing the Multivariate and Bivariate Johansen Co-integration test to see if the law of one price(LOP) holds in each market or not. The empirical results show that even though import prices from different countries affect each other in each South Korean major fishery product import market, there is no evidence of LOP in any fishery product import market, which means that none of the markets are integrated. Based on these results, we could expect that the three major fishery product import markets show monopolistic competition among import countries. we would also see whether or not any country plays the role of a price leader in any of the markets. Based on weak exogeneity test results, we might expect that the United States and Malaysia are price leaders in the South Korean Frozen Pollock Import Market and Frozen Long Arm Octopus Import Market, respectively; however, we need to study more on this in the future.

The Internet is taking up every single life of us with a huge speed of growth. If the ideal market called 'perfect competition' in economics will ever come true in this digital world, the sellers won't be able to have monopolistic profits above the marginal cost any more, letting the resource allocation much more efficient. This paper attempts to test whether this theory is true in e-market as well through observing price differences between online and offline retailers of extremely homogeneous products, CDs. Since most results from previous research were supporting the inefficiency of e-market in price level, price adjustment, and especially price dispersion, this article designed the research methodology most carefully. The results of pervious works are partly due to the immaturity of the Internet market or due to the uniqueness of the American CD market, where oligopolistic market players are significantly dominant. The analysis of price data of 20 titles from 20 retailers for five weeks supports that online market is more efficient than offline market with statistical significance in all the three dimensions. We could conclude that the e-market is going much more efficient at least compared to the offline market and the more would it be unless the sellers resist and prevent comparison-shopping.

Purpose - The movie market has the characteristics of being a perfectly competitive market as well as a pure monopolistic market at the same time. This is because there are competitors in the industry but prices, although not fixed, have not changed a lot. Price competition may not have spread, but the competition is focused on artistic value, and the degree of box office success is most important. The artistic value is determined in the course of the production process. However, the degree of box office success is dependent upon the marketing manager. The marketing strategy represents the difference in the standard or quality of the movie. Inherently, the marketing manager adopts the entertainment strategy based on the quality of the foundation of the completed movie. At this time, the marketing manager knows the pertinent information (high quality/low quality) regarding the movie. This research study tries to reveal what should be the reasonable movie marketing expense, dependent on the quality of the movie. Research design, data, and methodology - Using a game scenario with different market players, the goal of the research analysis is to find out the following. First, the marketing expense is determined to maximize the profits after film production. Second, after the production costs are already committed, the manufacturer gets to choose the marketing level. At this time, there will be a profit maximization point, considering the competition. The premise of the research is as follows: if it is a good movie of quality, positive word of mouth increasing the audience continuously slows down the speed of the demand curve. If the movie quality is bad, the negative word of mouth decreasing the audience gradually hastens the speed of the demand curve. On the marketing side, when the manufacturer invests heavily in the marketing expense of the movie, consumer expectations increase to drive up the audience numbers. On the other hand, it is difficult to improve the profits excessively. When the manufacturer invests in marketing a little bit, the marketing expense is only relatively committed, therefore a lot of demand cannot be gained. Results - If a fixed market share is in a competitive situation, a low quality manufacturer expends relatively more marketing expense. If the situation assumes two manufacturers spend the same for the cost of production, the high quality manufacturer takes more profit. If the manufacturer expends less marketing budget to save costs, the optimum profit cannot be achieved since the other party (opponent) grabs the initial market share. Conclusions - In conclusion, investment is essential for market share to increase. We must refrain from a zero-sum game and have models where the game participants pursue the creative profits together. In the current film industry, there is the dominating logic of winner and loser but we have to create a film industry environment where the participants can be altogether satisfied and live together.

This study empirically analyzes the relationship between market structure and R&D activities. Especially, the outcome of R&D activities could be imitated or plagiarized by nearby competitors before it is protected legally through patenting, it would work as a club good and its market structure need to be defined at the geographic level of city, county or ward rather than the whole nation. According to the regression results of this study using Survey on Technology Statistics of Small- and Medium-Sized Firms, individual firms' R&D investment is more active when market structure of area(city, county, or ward)-industry(two-digit industry) is monopolistic or oligopolistic rather than competitive. However, as the variable representing market structure is redefined over a geographic scope of 16 metropolitan areas or provinces, 6 regions, or the whole nation, the relationship between market structure and R&D activities seems to become weak. Moreover, when the R&D expenditure is divided by its source, more active R&D spending in a less competitive market is observed as long as it is procured by internal fund of the firm in question.
