WTO system has just begun and the development for fishing industry is being carried out. The task of National Federation of Fisheries Cooperatives(NFFC ) is not only to support producers' competitive edge, but also to realize the efficiency embodied in the businesses of NFFC itself. Then it can continue to compete other firms and offer the comprehensive services only when it achieves its efficiency. The efficiency of NFFC is the economies of scale and scope. NFFC should achieve its scale and scope economies to be efficient. NFFC needs to expand its size in fish distribution and banking business to have scale economies. Also, the communication and coordination systems among member-supporting, fish distribution, and banking business need to be strengthened to get its scope economies. It is interesting theoretically and in policy making to test the hypotheses that cooperatives are capable of offering the comprehensive services such as distribution, credit, and insurance to the members. It is meaningful to their development for agricultural and small businesses cooperatives as well as fisheries cooperatives to survive the fierce competition under WTO system. National Federation of Agricultural Cooperatives(NFAC) is much greater in business size than NFFC. The estimation and test in the multiproduct cost function of NFAC will show interesting results.

Urban spatial structure is closely related to the spatial distribution of urban economic activities. The spatial distribution pattern is no more than an aggregated expression of the location and/or relocation behavior of individual firms and establishments. In this respect, it is important to identify and examine the factors that affect the spatial behavior of individual firms for a more comprehensive understanding of urban space. Agglomeration economies are one of the most prominent urban economic phenomena in the modern metropolitan area. Most firms in an urban space seek external economies through the spatial clustering of their activities. Agglomeration economies feature prominently in the analysis of urban economic structure across urban areas. While the agglomeration economies between cities focus at the macro-scale of analysis, such economies within any given city focus more on the micro geographical scale. There have been a number of researches on agglomeration economies, among which there are relatively few approaches based on an intra-urban context. This proper explores the agglomeration economies at the micro scale and tries to reseal the spatial realization of the agglomeration economies within and between sectors. Three sectors are considered in the analysis; manufacturing, retail and service. The model is based on simultaneous equation systems combined with spatially weighted variables and estimated by the KRP estimators.

This study is to evaluate whether economies of scale exist in four categories of university libraries in the Korea. Regression analysis is used to fit a log-log equation to the total budget-output (total circulation, interlibrary lending and borrowing, reference transactions, hours opened, volumes added, automation and information indicator) for all the types of libraries. In results of the analysis, returns to scale are almost constant in the national and public libraries and larger libraries. But there is presence of economics of scale in private libraries and all of the libraries. Except for hours opened, economies of scale decrease more rapidly.

Transportation Economies of scale are the essential properties of hub networks. One critical property of the hub network design problem is to quantify cost savings which stem from economies of scale, the costs of operating hub facilities and opportunity costs associated with delays stemming from consolidation of traffic flows. Due to the NP-complete property of the hub location problem, however, most previous researchers have focused on the development of heuristic algorithms for approximate solutions. The purpose of this paper is to develop a hub network design model considering transportation economies of scale from the consolidation of traffic flows. The model is designed to consider the uniqueness of hub networks and to determine several cost components. The heuristic algorithms for the developed model are suggested and the results of the model are compared with recently published studies using real data. Results of the analysis show that the proposed model reflects transportation economies of scale due to consolidation of flows. This study can form not only the theoretical basis of an effective and rational hub network design but contribute to the assessment of existing and planned logistics systems.

This study is to evaluate the economies of scale of the public libraries in metropolitan cities. The results of the regression analysis confirm that for all samples of libraries there is diseconomies of scale in library operations (${\Sigma}b_{n}$≒6.14∼10.91). Therefore, all the types of public libraries should be improve productivity by user-based collection development, increasing circulation turnover rate, activation of in-library use, strengthening mobile library services, rational planning of services area, development of reading programs connected with the curriculum, a new branch library plans, etc.

The aim of the research study is to carve sustainable business strategies for the fashion communities in Ethiopia and Ukraine which are suffering today due to ever-increasing share of fast fashion consumerism. Fashion houses and international brands propagandize sustainability and consumption for better consumer base, where as originally sustainable local-based craftsmen still stay in the shade. Four communities/local designers are selected from the countries through the method of purposive sampling. Qualitative analysis is the basis of the research as we performed personal interviews and in-depth analysis of the communities to diagnose the problems and subsequently devise the solutions. In this research, we have studied and analyzed the problems faced by hereditary communities and ethnic designers in small and medium scale enterprise sector from two emerging economies. After the grounding the difficulties faced we advised strategies for sustainable future growth to the companies. The current academic literature on small and medium scale enterprises highlights the problems and solutions for general industry sectors. This paper brings attention to fashion communities and designers who promote national heritage and are struggling to survive in emerging economies due to industrialization and globalization. Moreover the comparison of the two geographies is unique in nature.

Using a panel data set covering 19 Korean manufacturing sectors for the period 2009-2015, this paper investigates the extent to which industry characteristics affect the mode of entering foreign markets. The estimation results across various specifications show that firms prefer affiliate sales to export as firm heterogeneity increases, implying positive effects of productivity regarding foreign relative to domestic operations. The motive for overseas production is reinforced as economies of scale at the plant level decrease and economies of scale at the corporate level increase.

Using a generalized translog multiproduct cost function model, this paper examines economies of scale and scope in the vertically-integrated Korean railway industry. The paper then conceptualizes that the Korea National Railroad (KNR) produces four outputs (passenger-kilometers, ton-kilometers of freight, average length of passenger trips, and average length of freight haul) using three input factors(labor, fuel and maintenance, and rolling stock and capital). Using time series data collected from the KNR's annual records for the years from 1977 to 2002, the simultaneous equation system consisting of a cost function and two input share equatins is estimated with the Zellner's iterative seemingly unrelated regression. The findings show that the cost function corresponding to a non-Cobb-Douglas, non-homothetic, and non-homogeneous production technology adequately represents the KNR's cost structure. On the other hand, the Korean railway industry experiences sizeable overall scale economies, which result from substantial product-specific scale economies associated with passenger-kilometers and freight ton-kilometers and from scope economies associated with their joint production. In addition, the magnitude of economies of scope is influenced largely by the ratio of passenger trips, and has increased over time as the former has increased while the latter has decreased.

Using a multiproduct translog cost function model, this paper examines the existence or absence of scale and scope economies in Seoul's urban bus industry. The Paper then conceptualizes that the bus firm produces three outputs (city, seat and local bus-kilometers) using low input factors(labor, capital, fuel and maintenance). Using 1996 annual observations for 81 Seoul's bus firms, the equation system consisting of a cost function and three input share equations is estimated with the nonlinear iterative Zellner method. The findings show that the cost function corresponding to a non-homothetic production technology with separability between local bus outputs and inputs adequately represents the structure of cost for Seoul's bus firms, and that the demand lot all input factors is quite inelastic with respect to their own price. On the other hand, nearly all firms experience mild overall economies or scale, but rather marked product-specific economies of scale with respect to all the three outputs. In addition, there appear to be substantial economies or scope associated with the joint production of city and seat bus services, while considerable diseconomies of scope associated with that of city and local bus services. These results indicate that the merger of smaller firms into larger firms with a fleet of approximately 200 buses would result in more cost-efficient bus services.
