소비자들의 다양한 요구와 국제적인 교류가 많아지면서 국제시장 개방등의 경제 환경으로 기업들간의 국 제적인 경쟁이 치열해지고 각종 제품들이 단수명화, 다양화함에 따라 전자 및 기타 제조업체들이 고임금, 고 물가, 고기술, 고기능화등의 어려움속에서도 지속적인 성장을 위한 방법을 강구하고 있다. 제조업들이 해결해 야할 문제는 품질 및 생산성의 향상, 소비자를 위한 서비스 개선, 수요창출을 도모할 수 있는 제품의 개발등 이다. 그중에서도 가장 큰 문제라고할수 있는 생산성에서는 선진 생산기술로써 가격경쟁력이 있어야한다는 숙제를 안고 있다. 본 연구 보고에서는 우리나라의 설계나 제조기술의 수준에 알맞는 업체 또는 제품제조업체에서 활용 가능하여 향후 국제 경쟁력(가격, 신뢰성, 품질)을 갖춘 제품을 개발할 수 있는 방법을 제안하고자 한다.

This study investigated a current situation of cable TV in order to seek and suggest cable TV's competitive superiority in the era of multiplatform media marketplace. This study suggested cable TV's direction from two aspects, short-term and mid and long-term strategies. As a result, it recommended that cable TV industry need to establish content circulation representatives, and reinforce multiformat contents suitable for various multiplatform uses, digital cable promotion, production of SO's originated programs, HD VOD, bundling services and diverse programs. As a long-term strategy, this study also suggested cable TV industry need to cooperate with smart TV industry in order to widen openness of its platform, and to provide not only diverse contents but also applications by offering two-way, mobile, and on-demand contents and services. Finally, this study proposed cable TV is needed to move towards a comprehensive media portal, which is a contents aggregator with the aforementioned business strategies.

Domestic coffee franchise market in South Korea has been rapidly growing along with developing the global coffee franchises as well as entering domestic franchise companies into the beverage market. Competitions in the markets are getting more accelerated and local franchises and owner-operated coffee shops are losing their market shares gradually as a result. Local franchises and owner-operated coffee shops in Daegu, however, are notable in that they are maintaining the competitiveness in the markets. This is a unique phenomenon, which deserves to be analyzed to identify the successful attributes as a case study. Important Performance Analysis (IPA) method has been employed for analyzing and its gap(i.e., difference between importance and performance) analysis shows that the price and quantity of coffee are the most important differentiating attributes of local and owner-operated coffee franchises in Daegu.

It is not valid to measure the degree of market power based on the markup of price over marginal market cost in an industry for which the market price of some inputs is not available because those inputs are then excluded in estimating the dual total cost function. If the roles of those inputs are ignored, the markup of price over marginal market cost is likely to be positive in the perfectly competitive industry. In order to have accurate market power markups for the environmentally regulated Korean iron and steel industry, in which the market price of raw material and the price of abatement capital are hard to obtain, in this paper, a dual cost function is derived given the optimal quantities of raw material and abatement capital, and then estimated jointly with the supply relation. The annual average degree of market power for the industry is estimated to be 0.49 over the period 1982~2001. Ignoring environmental regulation would overstate the degree of market power by about 8 percent.

본 논문에서는 서비스업의 매장에 설치된 POS(Point of sale) 또는 Smart device를 이용하여 빈 방 또는 빈 테이블 등의 서비스 가능 공간 수에 따라 실시간으로 가격이 변동되는 시스템을 제안한다. 고객 입장에서는 보다 싼 가격으로 서비스를 이용할 수 있으며, 매장주 입장에서는 한산한 시간에 경쟁력 있는 가격으로 고객을 유치할 수 있도록 도움을 준다. 고객은 애플리케이션에 접속하여 위치기반서비스를 통해 이용하고자하는 서비스 매장을 선택하여 실시간으로 변동되는 서비스 가격을 확인할 수 있으며, 예약 및 결제를 한 후, 일정 시간 내에 해당 매장에 가서 서비스를 이용할 수 있다. 매장주는 POS 또는 Smart device를 통해 자동 또는 수동으로 서비스 가격을 변동시킬 수 있다.

가전업의 CKD(Complete Knock Down)업무는 해외의 바이어나 현지공장에 가전제품을 구성하는 부품/반제품들을 개별 포장하여 수출하는 물류업무이다. 이러한 CKD 업무는 가격경쟁이 치열한 부분으로 경쟁력 강화를 위해 물류비의 절감이 요구되고 있다. 특히 CKD 업무의 경쟁력 강화를 위해서는 포장품질과 적재율 향상을 위한 포장/적재의 최적화가 이루어져야 하며, 이를 지원하는 Packing Optimization System 의 구축이 절실히 필요하다. 본 논문에서는 가전업 CKD의 업무특징과 업무환경의 변화에 대해 기술하였으며, 환경변화에 대한 대응방법으로 가전업 CKD 업무를 위한 Packing Optimization System 의 주요 기능과 업무 프로세스를 제시하였다. 그리고, 시뮬레이션 방법을 이용한 Packing Optimization system의 구현 사례를 예시하였다.

In this paper, we develop a dynamic structural model based on a dynamic supergame and measure market power for the Dallas-Forth Worth fluid milk market in the U.S. In particular, we compare the conduct parameter estimates from a static model with that from the dynamic model and illustrate bias in the market-power measure in a static model. And we also analyze the cyclical behavior of firm conduct. We find that the conduct parameter in a static model underestimates true market power if firms' behaviors are posited by a dynamic oligopoly game. We also verify that firm conduct in the Dallas-Forth Worth fluid milk market is countercyclical against demand shocks and expected future cost shocks. Our results indicate that the firms' conduct in the Dallas-Forth Worth fluid milk market is consistent with what dynamic oligopoly models predict. This implies that the firms consider not only the contemporary reactions of the other firms' but also future market competition. Therefore, the measurement of market power requires the specification of fully dynamic pricing relationship.

Environmental problems, such as the depletion of natural resources, global warming, and the destruction of ecological systems, are among the most serious problems facing the planet. Since the early 1990's, many OECD countries have undertaken green tax reforms by introducing new environmental taxes to protect the environment. Environmental taxes have been used as an instrument of environmental policy more than direct regulation because economic instruments have a comparative advantage over direct regulation in terms of cost effectiveness and pollution abatement incentives. However, one important reason why green tax reforms have not progressed is due to fears regarding the negative effect of environmental taxes on international competitiveness in the industry and trade sectors. The main purpose of this paper is to analyze the effects of environmental taxes on industry and trade by using a theoretical model to compare the effects of environmental taxes on pollution-intensive and energy-saving industries.

The purpose of this study is to investigate price transmissions between wholesale and retail markets regarding Jeju tangerines by employing co-integration analysis and vector error correction model. The results of this study are summarized as follows: First, the long-run equilibrium relationship was found among wholesale and retail markets in time series for level by distribution channel. Second, a short-run causality relationship was observed between wholesale and retail markets. Third, the long-run causality relationship between wholesale market and retail markets was found bidirectional and feedback effect. These results imply that the wholesale price performs a central role in establishing price in the tangerine market, and the wholesale market influences tangerine price. In conclusion, for the development of a competitive tangerine industry, it is necessary to aggressively promote the policy of supply and demand control of tangerine production through organizing producers.
