  • Research for establishing a legal framework for law, transactions, and enterprises in the era of the globalization - from the view point of private law, private international law, financial law and insolvency law

     View Summary

    This research project aimed at analysis of legal problems under the influence of the globalization. After many discussions we decided to focus on legal issues, which are being and will be caused by the development of the E-commerce. Since the E-commerce is in a sense an extreme way, in which the globalization has emerged, since the border does not have meaning any more. We discussed about financial law, insolvency law, contract law and tort law. We invited also some foreign colleagues to our meetings. The fruits of our final meeting will be published in coming summer as a book, Kono/Paulus/Rajak (ed.), Legal Problems of E-Commerce. I myself published two articles on the Internet auction and legal issues from the viewpoint of civil and commercial laws

  • Development of Economical Evaluation Method on Information System Investment during Monetary Crisis

     View Summary

    This research started from the recognition that the measurement of information technology assets contribution to the firms' value in the stock market is proper to the evaluation of industries' information system investment but not to one of firms' specific information system. At first, we selected technical efficiency index defined by the distance of the actual inputs and output combination from the production frontier in order to take cross section analyses of the interaction between individual banks' several types of assets and this efficiency during the time of 1993-99. Our statistical computer software was LIMDEP ver.8.0, Econometric Software Inc. the most difficult condition to this efficiency was how to define the production of bank. We tried five types of definition to measure it. The largest number of the statistically significant cases was founded when we used the definition of total value of deposit and net loans: loans deducted by nonperforming loans. It was also cleared that the computer software asset always had stable positive effect to this efficiency. This evaluation method will be applied to time series analysis of individual bank.Second, we realized that organization constitution and human capital of individual bank were decisive factors to information system working. We developed a statistical evaluation method of these factors. We mailed 600 IT strategy questionnaires to the blanch bureaus of Japan Postal Service by stratified sampling. The final number of returned answers was 326. The analyses of cross tabulation for these answers derived our third finding that on the job training and management decentralization were important to improve the technical efficiency concerning IT investment. Finally, balanced scorecards of four largest Japanese banking groups were introduced in order to diversify IT investment evaluation. Financial data were reciprocal movement to the other data including IT index. This was our forth finding

  • Joint Research on Policy in Converging Telecom and Broadcast

     View Summary

    Digital convergence poses a challenge to broadcasting and telecommunications policy on a global scale. Particularly digital innovation in the broadcasting sector enhances a rapid market convergence, which makes the boundary between the carriages of telecommunications and television signals blurry. Not only does digital convergence change the size and scope of telecommunications and broadcasting markets but it also has a great impact on our economic society. In order to enjoy the potential benefits of digital convergence, the public policy should be a pro-competitive one, since competitive pressures in the markets will bring opportunities for market players to provide new services and improve the quality of services, It is important to let competition work and let the players experiment with new ideas because it is competition that stimulates efficiency and ensures consumer sovereignty. We have organized an international research group to examine the current situation of digital convergence of telecommunications and broadcasting in Japan, United Kingdom and Germany, and to study the major policy issues, focusing on regulatory challenges those nations face from the international comparative point of view. The major implication that were distilled from our international comparative study is that a new regulatory paradigm is needed because competition can no longer be defined in terms of traditional markets alone. Competition policy must be analyzed across broadcasting and telecommunications industries. Since it is difficult to envisage the future deployment of digital convergence, reliance on competition policy would be the best solution. The immediate task of the government is to set the rules of the game as a way of enhancing fair competition and innovation. It is competition rather than regulation that simulates efficiency and diversification. Our study is published a book entitled Convergence of Telecommunications and Broadcasting in Japan, United Kingdom and Germany, Curzon Press, UK, 2001
