In this paper, we propose the coordination scheme in a single-manufacturer-multiple-retailer supply chain system. Traditionally, the bargaining power of the single manufacturer is superior to those of retailers. The business environment supported by the e-business scheme may give rise to new business behavior. The multitude of retailer requests the manufacturer to relax the his unilateral lot-sizing policy while they are willing to compensate more than the manufacturer's expected loss caused by abandon his superior bargaining power. The side payment aggregated by the multiple retailers is transferred to the manufacturer according to the degree of the manufacturer's relaxation from the current unilateral lot-sizing policy.

Game theory is adapted to a variety of domains such as economics, biology, engineering, political science, computer science, and philosophy in order to analyze economic behaviors. This research is an application of game theory to wireless communication. In particular, in terms of bargaining game we dealt with a multimedia resource allocation problem in wireless communication, which is rapidly spreading such as Wibro, WCDML, IPTV, etc. The algorithm is assumed to allocate multimedia resources to users who can choose and access differentiated media services. For this purpose, 3 utility function of users is devised to reflect quality of service (QoS) and price. We illustrated experimental results with synthesis data which were made to mimic real multimedia data, and analyzed differentiated service providing and the effect of the utility function.

Purpose - This study examines a bundling effect on production and distribution in a patent-protected industry. Despite the heavy use of bundling strategies in the information and technology industry, literature has paid scant attention to bundling of intellectual property rights. This study examines a theoretical exploration of the bundling effect on licensing behavior. Research design, data, and methodology - To address this behavior, we build a simplified model consisting of three stages: 1) bundling decision, 2) licensing agreement, and 3) competition. The subgame perfect Nash equilibrium is applied to the model. Results - A single-patent holder with superior technology grants its own license to the multiple-patent firm, thereby leaving the market. Anticipating the single right holder's licensing strategy, the multiple-patent firm offers a bundle, making the single-right holder's bargaining position weaker. Conclusions - Bundling is an effective business strategy, resulting in multiple products for a firm as it faces other firms with single-product lines in each market. Taking advantage of the multi-patent or multi-product lines, the firm utilizes the bundling strategy obtaining better technology from the standalone single-patent firms.

In order to ensure the wireless connectivity and seamless service to mobile users, the next generation network system will be an integration of multiple wireless access networks. In a heterogeneous wireless access system, bandwidth allocation becomes crucial for load balancing to avoid network congestion and improve system utilization efficiency. In this article, we propose a new dynamic bandwidth allocation scheme for hierarchical wireless network systems. First, we derive a multi-objective decision criterion for each access point. Second, a bargaining strategy selection algorithm is developed for the dynamic bandwidth re-allocation. Based on the intervenient Stackelberg game model, the proposed scheme effectively formulates the competitive interaction situation between several access points. The system performance of proposed scheme is evaluated by using extensive simulations. With a simulation study, it is confirmed that the proposed scheme can achieve better performance than other existing schemes under widely diverse network environments.

In this paper, a cross-layer resource allocation mechanism is proposed for wireless multimedia service. In particular, a game theory based on quality of service (QoS) for multimedia users is introduced to deal with the fairness of network resource allocation in wireless networks. Moreover, the channel states of wireless users are additionally regarded under the cross-layer design in WiMAX environment. In details, the bargaining solution is adopted to discover the efficient and fair resource allocation strategy for multimedia service in considering QoS in the peak signal-to-noise ratio (PSNR) and the channel states in the carrier-to-interface ratio (CINR). The proposed mechanism is illustrated and evaluated by simulation results of transmitting video sequences in WiMAX environment.

Negotiation is a process of reaching an agreement on the terms of a transaction. such as price, quantity, for two or more parties. Negotiation tries to maximize the benefits for all parties concerned. instead of using human-based negotiation. the e-commerce environment provides such an environment as adopting automated negotiation. Thus. choosing agent technology is appropriate for an automatic electronic negotiation platform. since autonomous software agents strive for the best deal on behalf of the human participants. Negotiation agents need a clear-cut definition of negotiation models or strategies. In reality, most bargaining systems embody nearly one negotiation model. In this article. we present a mobile agent negotiation system with reusable negotiation strategies that allows agents to dynamically embody a user's favorite negotiation strategy which can be preinstalled as a component in the system. We develop a prototype system, which is fully implemented in compliance with FIPA specifications, and then. describe the benefits of using the system.

Smart grid (SG) technology is now elevating the conventional power grid system to one that functions more cooperatively, responsively, and economically. When applied in an SG the demand side management (DSM) technique can improve its reliability by dynamically changing electricity consumption or rescheduling it. In this paper, we propose a new SG scheduling scheme that uses the DSM technique. To achieve effective SG management, we adopt a mixed pricing strategy based on the Rubinstein-Stahl bargaining game and a repeated game model. The proposed game-based pricing strategy provides energy routing for effective energy sharing and allows consumers to make informed decisions regarding their power consumption. Our approach can encourage consumers to schedule their power consumption profiles independently while minimizing their payment and the peak-to-average ratio (PAR). Through a simulation study, it is demonstrated that the proposed scheme can obtain a better performance than other existing schemes in terms of power consumption, price, average payment, etc.

최근 임금 인상과 고용증대에 중점을 두어 온 종래의 노동조합 활동의 영역이 환경보호와 빈곤퇴치와 같은 사회 현안으로 확대되면서 노동조합의 적극적인 사회 참여가 주목을 받고 있다. 이는 노동조합이 새로운 사회 문제에 고유의 단체교섭력을 바탕으로 그 책임을 담당하고 긍정적인 역할을 할 수 있는 경제주체로 인식되고 있기 때문이다. 본 논문은 미시적 경제 분석모형을 통하여 노동조합 운동이 지구 환경문제와 같은 사회적 이슈에도 기여할 수 있음을 설명한다. 국제 과점 무역 이론을 바탕으로 정부의 오염배출규제 정책 수립과정에서 기업과 노동조합이 자신들의 이익에 따른 전략적 선택을 추구하여 규제 정책 입안에 영향력을 행사하는 주인-대리인 모형을 분석한다. 이 분석으로부터 노동조합의 단체교섭력과 국제적 협력이 전지구적 배출오염을 완화하며 사회후생을 증진하는데 중요한 요인임을 확인하였으며, 이것은 WILL 2006에서 논의된 환경문제 완화를 위한 노동조합의 참여와 협력을 요청하는데 긍정적인 논거로서 제시될 수 있을 것이다.

우리 나라 5대 재벌그룹 기업들의 노동자 경영의사결정 참가의 실정을 단체협약과 노사협의회 규정들을 중심으로 살펴본 결과 다음의 결론들을 얻었다. 첫째, 분석대상 기업들은 장기전략 수준 및 작업현장 수준의 노사관계에서 노동자들의 경영의사결정 참가가 매우 저조한 상황에 처하여 있으므로 노사관계 주체들이 경영환경이 급변하고 있는 최근의 상황에 대하여 능동적 적극적 협력적으로 대처하지 못하는 등 대처능력 부족을 심각하게 드러내고 있다. 둘째, 이들 기업에서 단체교섭 수준의 사항들에 대하여는 단체교섭 수단으로, 장기전략 수준 및 작업현장 수준의 사항들에 대하여는 노사협의회 수단이 상대적으로 많이 활용되고 있다는 점이 발견되었다. 셋째, 노사협의회를 통한 노동자 경영의사결정 참가방식으로는 좀더 대립적인 분위기를 지닌 단체교섭과 충분한 거리를 유지할 수 있는 분리형의 형태가 참가범위의 확장이라는 면에서 보다 효율적인 것으로 생각되었다.
