Which dynamic pricing rule is most preferred by consumers?—Application of choice experiment

Abstract: This study investigates consumers’ preference for dynamic pricing rules using a choice experiment. Among alternative electricity pricing rules, time of use (TOU) is most preferred by consumers, and our estimation results show that TOU has the highest value of WTP among pricing rules. Furthermore, consumers’ characteristics affect their choice of a pricing rule. Our results show that risk preference in particular affects the choice probability of each pricing rule.

Supply-chain Simulation Integrated Discrete-event Modeling with System-Dynamics Modeling

Abstract: This paper describes a novel simulation framework that integrates discreteevent modeling with system-dynamics modeling. The former has strength in system performance evaluation; meanwhile, the later has an advantage of representing feedback mechanisms in complex systems. We are currently developing a hybrid-modeling framework, which combines discrete-event modeling with system dynamics modeling. The objectives of this framework are: (1) to simulate feedbacks of supply-chain activities in social system mechanisms, (2) to enable management simulation in long time terms, and finally (3) to clarify requirement specifications towards supply-chain management gaming. This paper summarizes this framework and represents application examples.

Responding to Hate in Contemporary Japan: Fragmenting Factors Obstructing Effective Ethnic Advocacy

Abstract: Zainichi Koreans, whose ancestral migration resulted from Japan’s colonization of the Korean Peninsula (1910–1945), are a culturally assimilated minority group now showing accelerated structural assimilation through naturalization and intermarriage with the Japanese majority. Nonetheless, since the mid-2000s, internet-mobilized right-wing activists have deployed hate campaigns against Zainichi Koreans or institutions they label as ‘anti-Japanese’. Conventional Zainichi Korean organizations, the pro-Democratic People’s Republic of Korea (DPRK) Chongryon and the pro-Republic of Korea (ROK) Mindan, have never formally collaborated to respond. Drawing on fieldwork (2011–2016) and secondary sources, this article explores factors that maintain fragmented ethnic advocacy. Focusing on Zainichi organizational responses to three hate incidents in Kyoto and Tokyo, I examine four dimensions: (a) preceding inter-organizational relationship, (b) bureaucratic inertia, (c) discordant framing strategies, and (d) external socio-political conditions. Organizational stances differ not just by pledged allegiance to different Korean nation-states, but also by organizational response to Japanese policy-making and the legislature. While both organizations adopt framing strategies based on the universal norm of human rights, Chongryon emphasizes minority education rights and Mindan problematizes hate speech per se. I argue that the contrasting strategies reflect broader socio-political factors more than organizational characteristics. Heavy reliance on the Japanese majority as the target audience maintains a fragmented Zainichi Korean advocacy.

Quality of Accounting Disclosures by Family Firms in Japan

Abstract: We investigate the quality of the accounting disclosures of publicly traded family firms in Japan. Family firms have strong incentives to create a long-term orientation and to bequeath their businesses to their descendants. This long-term orientation eliminates opportunistic earnings management and protects the firm’s reputation. These characteristics of family firms increase the effectiveness of monitoring and thus improve earnings quality. We find that, compared with non-family firms, family firms have high earnings quality on average. This finding is consistent with family firms’ effective monitoring, which stems from their above-described long-term orientation. We also find that the earnings quality of family firms in which the founder has executive authority over the firm is almost the same as it is for non-family firms. However, the long-term orientation of the founder could be different to that of the second generation.
