Revenue management (RM) has been widely used to model products characterized as perishable. Classical RM model assumed that price is the sole factor in the model. Thus price adjustment becomes a crucial and costly factor in business. In this paper, an optimal pricing model is developed based on minimization of soft customer cost, one kind of price adjustment cost and is solved by Lagrange multiplier method. It is formed by expected discounted revenue/bid price integrating quantity-based RM and pricing-based RM. Quantity-based RM consists of two capacity models, namely, booking limit and overbooking. Booking limit, built by assuming uncertain customer arrival, decides the optimal capacity allocation for two market segments. Overbooking determines the level of accepted order exceeding capacity to anticipate probability of cancellation. Furthermore, pricing-based RM models occupancy/demand rate influenced by internal and competitor price changes. In this paper, a mathematical model based on game theoretic approach is developed for two conditions of deterministic and stochastic demand. Based on the equilibrium point, the best strategy for both hotels can be determined.

Purpose - Typically, retailers will want PB(Private Brand) products to expand to the needs of low-PB loyal customers as well as existing PB(Private Brand) loyal customers. Therefore, a strategy of minimizing the share of the manufacturer brand in the distributor can be considered as a way to maximize the profit of the distributor. Research design, data, and methodology - In the previous study, the researches about the rivalry and conflict between the NB(National Brand) products and the PB products were mainly made. Previous studies did not model inter-national brand-level competition and inter-store competition. In addition, they have focused only on distributors' decisions from the manufacturer's perspective, and assume channel members have the same level of members(Choi, 1996). Results - This paper tries to apply the game theory to researches on how retailers can maximize the benefits of distributing NB(National Brand) products and PB(Private Brand) products, while distributors can also take advantage of their profits. Conclusions - It was found that providing cheap PBs did not help manufacturers and distributors. Distributors and manufacturers' profits were determined by consumers who purchased NB products that were higher in price and higher in perceived quality before providing existing PB products to consumers.

This paper illustrates the competition between the mobile pay and credit card systems by utilizing the theory of two-sided markets. Two firms, as platforms, maximize the profit collecting fees from consumers on one side and from retailers on the other side. Consumers pay to buy goods and services with mobile pay, credit card, or cash. The basic model is one that each platform maximizes its profit. We show that the fees for credit card holders and retailers are higher than the respective costs. The fee for retailers of the mobile payment is higher than its cost, while the buyer's fee may be higher or lower than its cost. Applied model is the one that employs the delegation game model. The total profit of the mobile pay system is composed of its profit and the weighted demand for the mobile pay. It is shown that buyers' fee under the applied model is lower than that under the basic model, resulting in an increase of the demand for the mobile pay. The fee for the retailers rises, albeit the sum of fees for the buyers and retailers falls. The profit for the mobile pay system is increased, while that for the credit card company stays the same.

Purpose - Against the backdrop of the recent intense political conflict in Korea's political circles, it is to reveal from an economic point of view the hidden aspects behind the hostile conflict between the two political forces. Design/methodology/approach - This paper is not a normative study to find a solution to political conflict, but a positive study to reveal the mechanism of reciprocity that exists between the two parties of conflict in real politics. Therefore, the analysis is based on game theory methodology. Findings - It is shown that the ruling party should choose a level of preemptive response that is neither insufficient nor excessive if it aims to avoid radical anti-government struggles by opposition parties. We also find that even if the chances of success of the opposition's radical offensive struggle are low, the use of that strategy is not necessarily reduced. In addition, we have obtained comparative static results that do not deviate much from our intuition. What's interesting is that unlike our intuition that the choice of the method will be indifferent if the marginal effects of radical and normal methods of struggle are the same, the opposition party rather chooses the normal method of struggle more often. Research implications or Originality - In forming the analytical model, it reflected the support of the general public following the opposition's struggle against the ruling party in order to capture real politics well in the conflict between the two opposing parties.

The purpose of this study is to provide basic data on sports entertainment programs by collecting data on unstructured data generated by Naver and Google for SBS entertainment program 'Women Who Score Goal', which began regular broadcast in June 2021, and analyzing public perceptions through data mining, semantic matrix, and CONCOR analysis. Data collection was conducted using Textom, and 27,911 cases of data accumulated for 16 months from June 16, 2021 to October 15, 2022. For the collected data, 80 key keywords related to 'Kick a Goal' were derived through simple frequency and TF-IDF analysis through data mining. Semantic network analysis was conducted to analyze the relationship between the top 80 keywords analyzed through this process. The centrality was derived through the UCINET 6.0 program using NetDraw of UCINET 6.0, understanding the characteristics of the network, and visualizing the connection relationship between keywords to express it clearly. CONCOR analysis was conducted to derive a cluster of words with similar characteristics based on the semantic network. As a result of the analysis, it was analyzed as a 'program' cluster related to the broadcast content of 'Kick a Goal' and a 'Soccer' cluster, a sports event of 'Kick a Goal'. In addition to the scenes about the game of the cast, it was analyzed as an 'Everyday Life' cluster about training and daily life, and a cluster about 'Broadcast Manipulation' that disappointed viewers with manipulation of the game content.

Purpose: This paper aims to reveal similarities and differences in behaviors in negative consumer-brand relationships. Thus, we focused on consumer motivation which includes intensity and direction of behaviors. The motivation for negative customer behavior has been discussed in the context of brand hate, but there is only limited research that has tried to measure it using quantitative methods. We are trying to measure customers' motivation in negative consumer-brand relationships and reveal the relationship between in-field customers' negative behaviors. Research design, data, and methodology: We adopt Reactive-Proactive aggression to measure the motivation of customers' behaviors in a negative consumer-brand relationship. Also, to reveal the relationship between in-field behavior and customer aggression, we survey Korean game communities to reactive-proactive aggression and behaviors, whether they participate, in each observed behavior during the serial negative consumer movements that occurred in the Korean game industry. As a methodology, we run multinomial logistic regression. Results: We observed 9 behaviors in this case, and we found that reactive-proactive aggression is related to participation and motivation of these behaviors. Conclusions: We suggest the potential of reactive-proactive aggression as motivation for customers' complex negative behaviors. Based on this potential, we hope reactive-proactive aggression could be used to reveal similarities and differences in behaviors in negative consumer-brand relationships.

With changing software industry structure, the emerging concept called Software Ecosystems (SECO) has various challenges that software engineers have to overcome. In market-driven software product development, they should have the capability to offer high value products to their own business and their customers in order to being competitive. Each stakeholder's perspectives and interests should be reconciled in terms of requirements so that engineers can offer high value products through requirements selection. Existing works have just mentioned the need of requirements negotiation between stakeholders without proposing detailed guidelines or practice. In this work, a systematic Requirements Negotiation process is proposed to resolve conflicts of interests of stakeholders in SECO. The interests of stakeholders are analyzed based on goal-based requirements engineering. The rationale of requirements conflict is structured for management. A stepwise requirements negotiation process aims at resolving requirements conflict by applying game theory concepts based on self-interested behaviors of stakeholders.

'Sportainment' like Golfzon, which combines the elements of sports and entertainment have a lot of potential and development as new business items in the view of overcome many limitations such as time and place in real sports. For ultimately developing baseball simulation game as 'sportainment', this paper as the early stage suggests the system which can analyze pitching and swing. Unlike speed-gun measurement for moving ball, it uses sensor technology to take information of ball speed and movement and reproduces graphic screen based on the information collected from sensors with graphic technology. Hitter's swing and hit-ball can be measured in the similar way. This baseball simulation game is expected to develop as one of successful indoor spotainment businesses such as Golfzon.
