| Research Abstract |
It was the purpose of this study to lay bare the nature and problems in the transformation of market system in the digital society by theoretical, institutional and empirical studies.
In the second year of the study, we continued to organize the research seminar as a platform for discussions focusing on the information and communication policy of the government. Specialists from economic, legal, policy, business and industrial organization studies exchanged their views on this platform. Furthermore, we kept contact with a group of researchers in University of California at Berkeley to enhance mutual understanding in the two countries. We invited Professor John Zysman to Tokyo and gave seminars to those who are interested in the academia and research institutions.
Part of our research resulted in the book, Toshihiko Hayashi ed., Competition Policy for the Next Generation Network, in which we advocated the necessary competition policy in the telecommunications industry which will deeply be affected by the advent of the next generation network. A more technical paper has been written by Toshihiko Hayashi, "NO and VNO : Interference, Competition and Growth. " The paper introduces a predator-prey model into the relationship between a network operator and a virtual network operator who borrows the network facilities from NO. The main conclusion is that by easing the term of access to NO facilities, encouraging the growth strategy of NO and VNO and leading NO to diversify its services, we can attain a long run equilibrium in which NO and VNO coexist in an expanded market.
The joint study arrangement that resulted from this study will be continued between UC Berkeley and Toshihiko Hayashi, who is planning a trip to Berkeley in October to discuss the possible agenda of further research.
