This paper analyzes how the international callback services affect on the international telecommunications market. We present a simple game-theoretic model to compare the equilibrium outcomes before and after the arrival of callback operator. We find that the callback service arises from the inefficiencies in the national telecommunications market and the accounting rate system between international telecommunications carriers. Also, we identify the conflicting interests among the governments and carriers, by examining how the callback service affects the collection rate, quantities demanded, carrier's profit and social welfare of each country.

Recently, FTA is quickly spreading out all over the world. In Korea, roles of trade in the economy are significantly important. Therefore, in order to adapt quickly to changed international trade environment, FTA negotiation and its agreements have been accelerated. In Korea, the trade deficit is expected to continue in telecommunications services sector. Meanwhile, pressures to open the market have been intensified in telecommunications services at WTO and FTA negotiations. Therefore, in the middle of opening the market, the expansion plans to increase the competitiveness of our telecommunications services are required to be searched. Thus, in this paper, we reviewed the Korea trade policy status related to telecommunications services based on realistic situation. Also, after reviewing the trade issues which are raised in the WTO and FTA negotiations, the major issues in WTO and FTA were driven to the lessons.

The consumer surplus under the open economy is greater than that under the closed economy from the viewpoint of social welfare. This indication has been proved when only the product market is considered. This article is to show how this result is changed if the R&D market as well as the product market is considered. We find the possibility that the closed economy is preferred to the open economy in case of the (international) R&D joint venture.

본 연구에서는 타 기술과의 융합을 통하여 그 영역이 지속적으로 확대되고 있는 정보보호 산업의 글로벌 시장동향을 분석하였다. 국내 정보보호 산업 시장은 2013년 현재 국내시장이 세계시장에서 차지하는 점유율이 매우 낮다는 점과 수차례의 보안사고로 인한 경각심 고조, 물리보안 수출의 확대 등의 요인을 고려하면 세계 정보보호 산업에 비해 높은 성장률을 보일 것으로 전망된다. 주목해야 할 점은 국내 시장은 제품시장이 주도하지만, 세계시장은 서비스 시장이 주도할 것이라는 전망이다. 따라서 국내 정보보호 산업의 현재의 부진을 극복하기 위해서는 상대적으로 부가가치가 높은 서비스 시장에 보다 중점을 둔 시장육성 전략이 요구된다.

이동통신시장의 산업구조가 스마트폰이 중심이 되는 ICT 생태계로 변화하면서, 새로운 ICT 환경에 부합하는 규제체계가 주요 선진국을 중심으로 다각적으로 논의되고 있다. 이 중에서, EU에서는 이동전화서비스를 도매와 소매로 구분하고, 세분화된 시장에서 이동통신사업자의 시장지배력 보유를 평가함으로써, 이동통신시장의 경쟁을 활성화하기 위한 규제제도 개선을 지속적으로 추진하고 있다. 이러한 가운데, 국내에서도 EU 방식을 도입하여 이동전화의 시장획정(market definition)을 현재보다 세분화하고, 객관적 평가기준에 따라 해당 사업자의 시장지배력 보유여부를 공정하게 판단하기 위한 방안이 논의되고 있다. 이에 본 연구에서는 ICT 생태계 환경 하에서 국내 이동통신 착신도매시장의 현행 시장지배력 평가를 위한 판단기준이 통신환경에 적합한지를 분석하고, 이론적으로 제기되는 새로운 평가요소의 반영 등을 포함한 시장지배력 평가에 대한 합리적 제도개선 및 시사점을 제시하고 있다.

As needs for telecommunications services diversify, an increasingly wide range of telecommunications services is becoming available in the market. Any subscriber can find a service to satisfy his/her telecommunication requirements and competition between providers to retain heavy users is increasing. Service price reductions are one retention strategy, although price reductions for one service can affect the individual-level usage for other services. Price reductions can also be imposed on a service provider by regulation. For these reasons, understanding how price reductions affect service usage is of growing importance to the telecommunications industry for purposes of pricing and tariff development. In this paper, we develop an individual-level usage model for telecommunications services and analyze the effects on usage of a price reduction. We apply the model to age-stratified aggregate traffic data for a Korean mobile telecommunication service provider. Finally, we develop a model to support a market segmentation and price reduction strategy.

Korean mobile telecommunications market is shifting from 2G to 3G service. Considering the revenue of voice-based communication has reached its maximum, 3G services can provide telecommunication companies with the opportunity to increase their revenues. As the competition in the market is becoming fierce, mobile carriers are trying to increase their profits by preventing their customers from switching to rivals. In this regard, managing customer can be a key success factor of the mobile telecommunications business by retaining existing customer. In this research, we tried to develop and test a model that aids further understanding of the determinants of continuance intention to use the current 3G service. We conducted empirical study through the analysis of 3G service users' data in Korea. The results indicated that continuance intention to use the current 3G is dependent on the customer's satisfaction with the service quality, handset, and brand image. We hope that analysis results will have significant implications in terms of both practical and theoretical aspects.

Market-oriented networks support various tasks in the market domain. We analyze trends in structural changes of such networks to adapt to preferences in general market movements. This analysis is different from conventional ones that focus on specific technologies. Instead, we focus on the paradigm shift of network technology from connectivity functionalities to platforms supporting business domains for direct modeling. Moreover, we analyze current development efforts of technologies based on popular and realistic solutions such as FIWARE, 5GinFIRE, IBN, IDN, and HNSP. Remarkably, we detail HNSP as an open research and development platform to experiment with business models and enable co-building with developers. We observe a clear paradigm shift of communications technology from a closed to an open job-shop style.

통신시장의 경쟁구조가 결합상품 시장을 중심으로 재편되면서 경품제공을 비롯하여 소비자를 위한 다양한 맞춤형 마케팅 전략이 시행되고 있다. 이러한 가운데, 최근 방송통신위원회에서는 통신사업자들의 마케팅 전략 중에서 과도한 경품지급에 대해 이용자차별 등을 근거로 과징금을 부여하였는데, 이와 관련하여 통신시장에서 현행 경품규제의 적합성 및 적정한 상한수준 등의 쟁점이슈가 다각적으로 제기되고 있다. 특히 2016년 7월부터 방송통신위원회와 유사한 제도를 유지했던 공정거래위원회에서 경품규제를 폐지함에 따라 현행 경품규제가 소비자후생의 관점에서 실질적으로 유효한지에 대한 논란도 나타나고 있는 실정이다. 즉, 다른 일반상품 시장과 달리 통신시장에만 경품규제를 유지해야 하는 이론적 및 실증적 근거의 타당성에 대한 논의가 필요하다는 것이다. 이에 본 연구에서는 결합상품 위주의 새로운 경쟁 환경 하에서 국내 통신시장에서 시행되는 현행 경품규제의 타당성을 실증적 근거를 기반으로 분석하고, 이를 기반으로 통신시장의 경품규제에 대한 합리적 개선방안 및 시사점을 모색하고자 한다.

Purpose - This paper analyzes the effect of the handset subsidy and the Mobile Number Portability subscriber subsidy regulation, which are the main regulation adopted in "Law on the Improvement of the Mobile Terminal Distribution System" (Mobile Terminal Distribution Act), on the social surplus, the consumer surplus and profits of telecommunications carriers. We focus our analysis on whether the service charge competition is stimulated enough so that it can compensate for the loss of subsidies. Research design, data, and methodology - We use simple economic model to assess the impact of the handset subsidy and the Mobile Number Portability subscriber subsidy regulation. Unlike the former researches on this topic, we depart from using Hotelling model, and instead use the switching cost model, which uses switching cost as a parameter of market powers of telecommunications carriers. We also study the effect of the two different regulations when they are adopted both independently and concurrently. Results - If the market powers of telecommunications carriers are over certain threshold, contrary to the regulatory agency's assertion, the service charge competition would not be stimulated enough to compensate for the deduction in the subsidies, and thus the consumer surplus is compromised. Number Portability subsidy, especially, undermines the rival's market power and thus reduces the service charge. On the other hand, the regulations will also increase the profits of telecommunications carriers. However, social surplus is maximized when both of the regulations are present because the regulations reduces the frequency of switching handsets inefficiently. Conclusions - In enacting the Mobile Terminal Distribution Act, the telecommunications regulatory agency asserted that the regulation on subsidies will stimulate service charge competition, and in the long run, enhance the consumer surplus. However, contrary to the regulatory agency's assertion, subsidy regulation, especially the regulation on Number Portability subsidy, reduces consumer surplus. On the other hand, the Mobile Terminal Distribution Act can also increase the profits of telecommunications carriers because it decreases competition among the telecommunications carriers. However, the Mobile Terminal Distribution Act can increase the social surplus because it reduces inefficient switching of handsets.
