In recent years, technology firms have been facing a highly competitive environment on a global scale. The firms are accelerating to establish R&D sites abroad in order to access global knowledge resources. In this context, global R&D projects have become more complex and R&D bridge managers (BMs), who facilitate global research collaboration, play a pivotal role here. This study aims to investigate the difficulties that BMs are facing and to explore the roles of BMs in global R&D projects. We interviewed nine BMs who have facilitated global R&D projects and propose a model depicting four common and critical difficulties present in facilitating research collaboration between teams in the home country and foreign R&D teams. The unique contribution of this paper focuses on the individual managerial level, while most previous studies on global R&D mainly focused on an organizational level.

<p>By using a travel demand forecasting model that covers both inner-city and inter-city transportations of whole of Japan, we discuss economically efficient regional CO₂ emissions reduction quotas. We calculate the CO₂ emissions reduction by introducing a fuel tax as a countermeasure against global warming at each region and illustrate the results can be applied to decide the regional quotas. In our analysis, it has been shown that the CO₂ emissions reduction per capita due to the taxation, which is equal to the region's reduction quota per capita, is bigger in rural areas than in urban areas.</p>

The purpose of this paper is to develop the SCGE model for finely-divided regions in order to conduct positive analysis and estimate economic impacts. In our study, the model deals with 2,342 cites in Japan and takes into account inter-regional freight transport, commuting and capital flows between each city.<br>In the positive analysis, the developed model is applied to the case of Great East Japan Earthquake. The damage of the earthquake is expressed as decrease in the production efficiency of firms, which is assumed to be equivalent to the rate of capital stock decrease in the inland and coast regions in the suffered area, i.e., Iwate, Miyagi, Fukushima, and Ibaraki Prefecture. The result shows not only that large economic damage has occurred in these suffered areas, but also that the economic damage has affected all East Japan and industrial areas of Chubu, Kinki, Chugoku and Kyushu District.

本稿では,相互意思決定状況を主観的に認識する主体を想定したハイパーゲーム理論を紹介する.通常のゲーム理論は,ゲームのルールが主体間で共有されている際の合理的な意思決定を追求するのに対し,ハイパーゲーム理論では,そもそもゲームの構造に関する認識に主体間で差異があるような状況を考え,そのことが主体の意思決定やゲームの結果に及ぼす影響について分析する.さらにゲームの結果の認識のあり方へのフィードバックについても扱い,認識と意思決定の相互関係を論じるものである.具体的な事例をもとにいくつかのハイパーゲームモデルを紹介しながら,その独自の問題意識について解説する.
