Japan University of Economics

Gojo, Japan

Japan University of Economics , abbreviated as Nikkeidai , is a private university in Dazaifu, Fukuoka, Japan. The school was established in 1968 and adopted the present name in 2007, to reflect its nationwide character following the successful establishment of campuses in both Kobe and Tokyo . It is officially the Fukuoka campus of the Japan University of Economics which is run by the Tsuzuki Integrated Educational Corporation, a major supplier of higher education in Japan. Students live in one of two dormitories, called Oxford House and Cambridge House, to in honor of the famous Oxford and Cambridge universities. The current chancellor of the university is the daughter of Yasuhisa Tsuzuki, who had resigned to pursue private interests following allegations of molesting staff that were ultimately unproven in court but damaging nonetheless to the image of the institution.The university under the leadership of the new Chancellor, has gone on to become one of the three largest providers in Japan of education to overseas students.

Internet of Things (IoT) is now making a new industrial revolution, which includes 'Industrie4.0' in Germany, 'Industrial Internet' in US, 'Made in China 2025' in China, and the 'Industrial Value Chain Initiative (IVI)' in Japan. In the modern global, competitive, and collaborative business environment, IoT services must be designed as a business ecosystem. Although many business-model design methods, including our own design method presented in PICMET2015, have been proposed, there exist few business-ecosystem design methods that target IoT services especially. Here, a business-ecosystem design method is proposed for IoT services using an 'Open & Closed Strategy Canvas,' on which designers can recognize both a closed area where the company keeps and strengthens their core competence, and an open area, where complementary companies provide resources (knowledge resource, manufacturing resource, and deployment resource) to the business ecosystem. © 2016 Portland International Conference on Management of Engineering and Technology, Inc.

We apply a choice experiment to estimate additional willingness to pay for Campylobacter-reduced chicken compared with normal chicken. We select Japanese consumers as an example because Japan is the world's largest chicken importer. The additional willingness to pay is estimated to be 38.87 JPY (about 0.39 USD)/150 g (when food poisoning levels reduced from 1/500 to 1/1,000) and 80.29 JPY (about 0.80 USD)/150 g (1/2,000). These values are high enough to cover additional associated costs, implying that producers' spontaneous provision of Campylobacter-reduced chicken is feasible. Our study is the first to confirm this fact. In addition, we elucidate consumers' characteristics that push up additional willingness to pay, thereby drawing useful implications for promoting safer chicken. Good progress in providing safer chicken in Japan would create more global business opportunities for companies and might trigger expansion of pathogen-reduced table meat worldwide. © 2017 by Wiley Periodicals, Inc.

With the popularization of high-speed and high-capacity communication networks, machine-to-machine (M2M) communication has received significant attention. However, although the related technologies have been actively investigated, creating new businesses based on M2M communication is difficult. The information and communication technology community should take not only system modeling but also business modeling into account for monetization. This study proposes a service design and modeling method of M2M businesses based on the SCAI (Share-Connect-Analyze-Identify) model, which was proposed in PICMET 2014 [10]. The proposed method is explained using a trial application to smart home M2M services. © 2014 Portland International Conference on Management of Engineering and Technology.

Focusing on the case of Senegal under the former President, Abdoulaye Wade, this article examines the impact party politics has on service delivery in urban areas controlled by opposition parties. Senegal's decentralisation process provided opportunities for the central government to deliberately reduce the autonomy of local government under conditions in which the latter could be held accountable for good service delivery and increase autonomy when local government could be targeted for poor performance - actions manifested through backtracking on political decentralisation, undermining fiscal decentralisation, and augmenting administrative ambiguity. The case offers useful implications for donors involved in decentralisation and urban service-delivery projects in opposition-controlled cities. © 2014 Overseas Development Institute.

This paper measures the technical efficiency of joint public-private venture railways and private railways in Japan using the Stochastic Frontier Analysis. We compare the following four groups using student’s t-tests : Group 1 is composed of rural railways operated by joint public-private ventures, Group 2 is composed of rural railways operated by the private sector, Group 3 is composed of urban rapid transit railways operated by joint publicprivate ventures, and Group 4 is composed of urban rapid transit railways operated by the private sector. The null hypothesis that there is no difference between Group 3 and Group 4 on mean efficiency is not rejected. © 2015, Japan Section of the Regional Science Association International.

Recent empirics report that transport cost reductions significantly contribute to rapidly growing world trade. This article develops a reciprocal market model of intra-industry trade with transboundary pollution from consumption to consider how market integration in the form of transport cost reductions affects the noncooperative choice of an environmental policy and the equilibrium welfare. I show that market integration can improve welfare locally, but that welfare under any non-prohibitive trade cost can not be higher than welfare under autarky. This possibility of trade losses exhibits a sharp contrast to the case of production-generated pollution. © 2012 Copyright Taylor and Francis Group, LLC.

There exist a lot of incremental innovations to solve superficial problems. Breakthrough type innovation, however, is expected to solve latent problems. Consequently it realizes safe and wealthy society and competitive economy. Incremental innovation is realized by summation of several solutions in a conventional fixed dimension. The authors think that breakthrough type innovation is realized by expanding this dimension to missing dimension. © 2014 Portland International Conference on Management of Engineering and Technology.

Clark and Konrad (2007) introduce the weakest link against the best shot property to the Colonel Blotto game where the defendant has to win all the battle fields while the attacker only needs to win at least one battlefield. They characterize the Nash equilibrium assuming that the attacker attacks all the battlefields simultaneously. We construct a two stage model and endogenize the attacker's attack pattern. We show that the attacker chooses a sequential attack pattern in the subgame perfect Nash equilibrium. Therefore, the game analyzed by Clark and Konrad (2007) is never realized. We also conducted experiments and found that the subjects' behavior was inconsistent to theoretical predictions. Both players overinvested and the variances were large. In the simultaneous game, the attackers took a guerrira strategy at 30% of the time in which they invested only in one battlefield and the defenders took a surrender strategy at 11% of the time in which they invested nothing in the simultaneous game. Both players invested more in period 1 than in period 2 in the sequential game. Although all of these are inconsistent to the theoretical predictions, the winning probability of a game was consistent to the theoretical prediction in the simultaneous games, but it was lower than the theoretical prediction in the sequential games. We conclude that the subjects' irrational behavior is mainly a rational response to his/her opponent's irrational behavior. Our model can explain terrorism, cyber terrorism, lobbying, and patent trolls and the huge gap between the theory and the experiments are important considering the significance of the problems.

Economic growth is stalling globally. New business schemes and/or new industrial architectures must be created to resolve this situation; innovation is necessary. Conventional innovation has been created mainly by technologies. Future innovation or new industries, however, will be born through non-technology fields. The authors propose a cultural study approach to create new industrial architectures. Recently almost all Otaku-based anime characters and games are actually combinations of earlier characters and plots, which constitute a database. This kind of sub-culture, postmodern culture, is a world of reference and remixes. Neither grand narratives nor objectives are necessary. What comes from the database, grand non-narrative, is designated as a "simulacre" or secondary creation from originals. The authors applied this "simulacre" model to industrial architecture. More than 30 years ago, industry sought and achieved vertical integration. Large computer companies served all sectors of computer production and merchant such as IC chips, OS, and applications. Modern architecture has become horizontal integrated, where IC chip OEMs provide only chips, and OS suppliers serve the OS business. The postmodern culture suggests that the new industrial architecture is based on a "simulacre" of these conventional sectors. This model is verified to explain recent innovations such as i-Phones and cloud computing businesses. © 2013 PICMET.
