Research Note: Analysis of the Characteristics of Victims in Information Security Incident Damages: The Case of Japanese Internet Users

In this article, the authors investigate the attributes of victims in information security incident damages for the purpose of reducing the damages. The Information-Technology Promotion Agency, Japan, in 2010, conducted an Internet survey targeted to Japanese Internet home users entitled, “Survey of awareness toward information security incidents” that is used in this article. Using micro data collected from this survey, they employed multinomial logit regression analysis to show factors affecting the user’s experience of the incidents of damage through particular incidents. They concluded that the overconfidence regarding information security knowledge increased the probability for phishing and spoofing.     

Research Note: A High Resolution Graph Viewer for Multi-monitor Visualization Environment

Bigdata analysis is a hot topic in all fields of science. Particularly in scientific fields investigating data relations, observation and analysis of relation among diverse data sets has begun to play a role of great importance. A graph is a representative expression for the purpose and many graph viewers and tools prevail today. However, most of these graph viewers do not offer the capability for displaying graphs on a multi-monitor visualization environment, even though multi-monitor visualization environment facilitates scientists in understanding data in a more detailed and intuitive manner. In this paper, our first exploration towards a high resolution graph viewer for a multi-monitor visualization environment is explored and reported.     

Research Note: Statistical Analysis on E-mail Magazines used by Japanese Prime Ministers

This paper presents a multiple regression analysis of the relationship between the frequencies of political keywords on cabinet e-mail magazines and cabinet approval ratings from the period of April 2001 to September 2009 in Japan. The authors found that Prime Minister Junichiro Koizumi was the only Prime Minister who utilized a cabinet e-mail magazine as a strong political tool. Other prime ministers from the Liberal Democratic Party failed to utilize this type of magazine as a tool. In addition, we concluded that Japanese voters did not highly value the Koizumi Cabinet’s economic performance, but highly evaluated its message in the electronic information space of political economy.

The Boosting Effect of E-WOM on Macro-level Consumption: A Cross-Industry Empirical Analysis in Japan

In this study, we carry out an empirical analysis on how electronic word-of-mouth (hereinafter “e-WOM”) marketing on e-WOM websites and electronic-commerce websites on the Internet boosts consumption on a macro-level. In our analysis, we conduct a model analysis of consumer behavior using data composed of more than 30,000 questionnaire surveys and quantitatively find the elasticity coefficient of the boost to consumption by performing a two-step GMM (generalized method of moments), which uses instrumental variables. The results of the analysis show e-WOM significantly increased expenditures in six fields: computers, electrical appliances, etc.; music; hobbies; clothing, accessories, etc.; beauty products, etc.; and goods for everyday life, etc. Furthermore, there was no field that had a significantly negative value. These results showed that, in the majority of the target fields, e-WOM had not only the effect of winning customers from the competition, but also the effect of boosting consumption on a macro-level. In addition, even from people’s subjective evaluations, there were many in all the generational groups who said that e-WOM boosted expenditures.     

The Effect of Information Communication Technology and Corporate Organizational Reforms on Productivity in Japan: Firm- level Evidence

Our main objective in this paper is to understand how Japanese firms can increase productivity by utilizing Information and Communication Technology (ICT). E-commerce, BPO (Business Process Outsourcing), and SCM (Supply Chain Management) are popular in Japan, so a new type of ICT might offer an opportunity for Japanese firms to change current business relations or to start up new ones. The novelty of this paper is in its empirical study of the combination of ICT promotion and a variety of business organizational changes needed to discover which type of business organizational change is suitable for raising productivity in Japan. For workplace organization within firms, we discuss the decentralization or centralization of decision-making power and the flattening of the corporate hierarchy. For business relational changes, we discuss the outsourcing of the business process and the start up of new business relations. Our main result is that in general, the promotion of ICT has better effects in reforms related to changes in business relations among business partners, rather than to reforms within a firm. Starting up new business relations that require planning and R&D show the best chances of raising productivity using ICT promotion.     

The Effects of Proposals for Basic Pension Reform on the Income Distribution of the Elderly in Japan

The aging of the population in Japan is a serious problem, and the reform of the public pension scheme is a major political issue. Although the 2004 pension reform was enforced to ensure a sustainable pension system in such an aging society, people remain quite apprehensive about the pension system. Consequently, various sectors have created new proposals for pension reform to overcome these problems, and it has become a recent policy debate. The objective of this article is to prepare projections for the income distribution of households containing elderly people using the Japanese microsimulation model, INAHSIM (Integrated Analytical Model for Household Simulation), and to evaluate the effect of the proposals on the living standards of the elderly. According to the simulation results, the problem of very low pension amounts for the elderly does not appear to be growing. However, changes in co-resident families of the elderly, such as the increase in the number of people living alone, may cause a decline in their standard of living. The author points out the problems of the previously proposed reform plans and proposes an alternative reform plan based on the perspective used in this paper.     

科研经费不是“唐僧肉”

郭沫若诗云“千刀当剐唐僧肉”,那是因为陈玄奘虔信佛教,立志取经西天,可是他恪守佛家“慈悲”之说,迂拘软弱,不明事理,易受愚弄,屡为妖魔所欺骗。毛主席答诗则认为“僧是愚氓犹可训”,把矛头对准了妖魔鬼蜮。由此想开去,我感到时下的“科研经费管理”,那些把握“财政大权”的“高官”,     

A Conjoint Analysis of a Next Generation Network (NGN) in Japan

A conjoint analysis on a Web survey in 2010 with 160 participants and 8 questions shows that a Marginal Willingness To Pay (MWTP) on a Next Generation Network (NGN) of Flet’s Hikari Next is lower than its actual price as provided by NTT East. Conjoint analysis is one application of conditional logit. MWTP is WTP when one unit of property is increased, and MWTP is used to verify how much each person evaluates each property. Higher transmission speed, digital TV availability, and higher Internet security affect the MWTP positively, and the amount of the monthly payment of NGN affects the MWTP negatively. Therefore, it is assumed that the NGN of Flet’s Hikari Next by NTT East will be accepted by potential customers and diffused as a major communications service of NTT East and NTT West. NGN providers may be able to maximize their benefits by adjusting the NGN of Flet’s Hikari Next property to meet customer demands, especially in digital TV availability, higher transmission speed, and communications security.     

The Effect of Changes in Nuptiality Behavior after the 1980s on the Poverty Rate for the Elderly in Japan -Analysis Using a Dynamic Microsimulation Model-

The social security system in Japan was developed under the premise that postwar families represented the most common type of family. A “postwar famil” refers to a family in which: (1) men and women are married; (2) husbands work as regular employees and wives are dependent homemakers; and (3) husbands and wives seldom get divorced. Therefore, the social security system is particularly generous towards dependent wives and widows. However, these premises are no longer valid because Japanese nuptiality behavior has completely changed since the 1980s. Marriage rates have decreased and divorce rates have significantly increased. Nevertheless, society still suffers from a wage inequality between men and women. As a result, the number of never-married or divorced elderly women will increase, and these women might face a serious poverty risk in the future. In this study, the author makes simulations of the living arrangements and poverty rates for the elderly in Japan and evaluates the effect of changes in nuptiality behavior on these poverty rates using a dynamic microsimulation model. The simulation results indicate that changes in nuptiality behavior will affect the poverty rate for elderly women, but not for elderly men.
