Dynamic Microsimulation Modeling for Policy Support: An Application to Belgium and possibilities for Japan

This paper provides an overview of dynamic microsimulation modeling as well as its recent developments. It then discusses in detail a recent trend in microsimulation research, which uses alignment methodologies to simulate microsimulation models in conjunction with macro-economic models. The goal of this ??top down-integrated approach?? is to jointly assess the budgetary costs of demographic ageing and pension reform, as well as their consequences on the adequacy of pensions. This paper then discusses, also in detail, how such an integrated approach using shared demographic and macroeconomic assumptions has been developed in Belgium. It describes the dynamic microsimulation model MIDAS, highlighting how it aligns to the simulation results of the semi-aggregate model MALTESE. Finally, this paper suggests that the joint assessment using the joint application of two similar models might be useful to assess pension reform in the Japanese context.

Impact of Online Customer Reviews on Sales Outcomes: An Empirical Study Based on Prospect Theory

This study examines the influence of the valence of online customer reviews on sales outcomes based on prospect theory. Numerous studies have revealed the importance of customer reviews in online marketing. However, only few studies have explored the impact of online customer reviews on sales outcomes in the dynamic process. Prior studies in behavioral economics literature have indicated that people differently value gains and losses and that losses have more emotional impact than an equivalent amount of gains. This study verifies whether prospect theory applies to the relation between online customer reviews and sales outcomes. Relevant data were collected from Amazon.co.jp, and three statistical models were employed to investigate the relation between the two factors. Major findings confirm that negative customer reviews considerably impact online sales than positive reviews. Furthermore, the findings indicate that the marginal effects of positive and negative reviews decrease with the increase in their volume. The results of this study will enable marketers to compare the relative sales effects of different types of customer reviews and improve the effectiveness of customer service management.

An Internet Access Solution: MANET Routing and a Gateway Selection Approach for Disaster Scenarios

After natural and man-made disasters, the telecommunication infrastructure is usually severely damaged, thus hampering communication and rescue services. It is impossible for disaster victims to make use of communication devices such as cellular phones, iPads, or their laptops to make a connection with the outside world (Internet). With infrastructure less and decentralized features, the mobile ad hoc network (MANET) can play an important role in improving communication in post-disaster affected areas. Therefore, the important functionalities of a MANET that allow users to create dynamically configurable wireless networks without fixed infrastructure using common devices such as mobile phones is necessary. This paper reports on the development of new techniques for routing selection and gateway load balancing in MANETs. Network fairness, throughput, and packet delays are measured empirically. The proposed mechanisms can reduce network congestion and consequently improve communication in affected areas.     

The Substitution Effect of Mobile Games on Console Games: An Empirical Analysis of the Japanese Video Game Industry

In this paper, we discuss the substitution effects between mobile games and console games. We estimate such effects by a fixed-effect regression with instrumental variables using panel data of about 100,000 observations. The results showed that the substitution effects of playing smart devices on 3DS, Wii, and PSP were recognizable, but did not have significant effects on PS3, and the substitution effects on PSP were very small. Therefore, mobile games had a substitution effect on casual console games, or on console games in which the play situation resembled mobile games. In addition, the substitution effects were at most about 0.1. The substitution effects were small. Our results indicate that mobile games represent the pioneers in the new market of gaming at least during our observation period. But new games and traditional games will coexist for a while.     

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.
