This paper experimentally studies the performance of negotiation considering individual and party, like a country, share of benefit over the best ones. It experiments two-stage bargaining games, internal and external negotiations. From the experimental results, this paper shows strong tendency to select fair allocation in the internal negotiations, but the tendency would be weaker with attractive outside option. In addition, the outside option may claim difference in individual benefit. From the regressions on individual performance in the negotiations, being a proposing party would matter to enhance the performance. However, relative individual performance within party fairness matters. Still attractive no-agreement options happen to break the tendency. As policy implication for trade negotiation, this paper warns that possible loss in individual benefit from not active participation to the external negotiations, no active role of proposer in case that players stick to internal allocations, and deviation of advantageous sector due to attractive outside options.

This paper suggests that the profit sharing contract can be Pareto optimal for both supplier and the purchaser. It is shown that Pareto optimal risk sharing contract can be obtained even though the decisions are made in a decentralized manner. The effect of risk attitude of the members of the supply chain is discussed. We examined various aspects of the risk sharing contract such as risk altitude, bargaining power, and cost of information system. The different risk attitude changes the optimal parameters and decision variables. Especially, we proved that, when both the supplier and the purchaser are risk averse, the purchaser orders less quantity than when the one is risk neutral and the other is risk averse. If the fixed cost for the information system is big enough to satisfy a certain condition, it is Pareto optimal not to share the profit and the purchaser takes all the risk even though he is risk averse.

The economic operation of a utility in a deregulated environment brings about optimization problems different from those in vertically integrated one［1］. While each utility operates its own generation capacity to maximize profit, the market operator (or system operator) manages and allocates all the system resources and facilities to achieve the maximum social welfare. This paper presents a sequential application of non-cooperative and cooperative game theories in analyzing the entire power transaction process.

Pooling system of jointly shipping farm products aims to realize economies of scale for it's farm products and strengthen bargaining power for the farmers. As adapting to pooling system, price received by farmers and competitive power of our farm products can be enhanced. Pooling system especially in Cheon-an pear and horticultural primary cooperatives is found to be required, because the pooling system is not introduced yet although the area is main region for domestic pear production. This study aims at establishing the appropriate pooling system and it's strengthening strategies in this cooperatives through survey of local producers' group in this cooperatives and case studies of successful pear primary cooperatives.

The objective of this study is to analyze factors affecting usage of b2b e-marketplace. For this purpose, we suggest a research framework where the factors are e-business infrastructure, expectation of competitive advantages and perceived barriers with current and future usages as result variables. For empirical test, 219 companies are surveyed and 177 valid ones among them are analyzed. In result, e-business infrastructure and competitive advantage affect to both current and future usage positively and perceived barriers affect to future usage negatively. The results shows the following two: First, many companies expect improvement of competitive advantages such as bargaining power and efficiency by usage of e-marketplace. Second, for more aggressive usage of e-marketplace, it is important not only to build e-business infrastructure but also to resolve perceived barriers.

The purpose of this research is to investigate consumers' experience of using Internet used-item markets in order to determine their motives in such activity. In terms of the Internet used-item market, (1) it contributes to a sound culture of consumption by recycling, (2) as a C2C market, it retains characteristics fundamentally different from the existing one-way type of market, (3) and it offers different characteristics from existing offline-based flea markets. Two significant themes emerged from the study results. First, users of Internet used-item markets passed through various stages such as novice, addict, and expert and learned the techniques for utilizing the used-item market. Second, for fast transactions with generalized Internet banking and the increasing trend for price bargaining emotional exchange among members is being transformed into the pursuit of transactional efficiency.

This study is to establish the validity of EDI adoption model Korean Companies. The research model is hypothesized in the external factors of company directly affect on EDI adoaption and the internal factors of company moderately affect on the direct effect. The external factors of company consists of economic factors, organizational power factors, and technological factor. The internal factors of company consists of the size of the company, innovative tendency of the top management, and maturity of the information technology. In the result of data analysis-the data were collected from a total of 81 companies in 6 industries adopted variables are the existence of EDI standard, transaction frequency, inter-organizational bargaining power, and pressure from industry association. Also size of the company and innovative tendency of the top management in a company's internal factors were adopted as moderate variables.

This study investigates the effect of power dynamics on R&D and market performances. Various types of relationships in a supply chain are considered. An R&D company offering new technology for product quality and a manufacturer responsible for both production and sales are utilized as subjects. The company with bargaining power differs with respect to the supply chain situation in practice, and no fixed single relationship and supply chain structure exist. However, only a few studies have considered the various relationships among players in a supply chain and their effects on performance. Therefore, we propose three models with different supply chain structures and power dynamics among players. This study contributes to the academia and supply chain practice by revealing the different characteristics of supply chain models.

In this study, we developed hybrid control algorithms in smart base stations (SBSs) along with devised communication, caching, and computing techniques. In the proposed scheme, SBSs are equipped with computing power and data storage to collectively offload the computation from mobile user equipment and to cache the data from clouds. To combine in a refined manner the communication, caching, and computing algorithms, game theory is adopted to characterize competitive and cooperative interactions. The main contribution of our proposed scheme is to illuminate the ultimate synergy behind a fully integrated approach, while providing excellent adaptability and flexibility to satisfy the different performance requirements. Simulation results demonstrate that the proposed approach can outperform existing schemes by approximately 5% to 15% in terms of bandwidth utilization, access delay, and system throughput.

Psycho-social-spiritual care should be included with comprehensive nursing care of cancer patient. Because of human being have four dimensions as physical, psychological, social and spiritual dimension and they do interactional relationship with themselves, others and God. So caregivers of cancer patient have to recognize what they have psycho-social-spiritual needs and have to consider how caregivers can combine these in comprehensive nursing care. Cancer patient will be experienced shock, feeling of crisis and fear of death and will be showed denial, anger, bargaining, depression, accept or give-up, hope, spiritual distress and spiritual needs to which help them to do some rituals or interactions according their religion. Loving attitude is essential of cancer patient care especially of psycho-social-spiritual care. Dr. Kim and her some colleques investigated about this and find out 10 concepts(Caring Behaviors) by Graunded Theory Methodology. They are Noticing, Participating, Sharing, Active Listening, Complimenting, Companioning, Comforting, Hoping, Forgiving, Accepting.
