An economic investigation of Japanese distribution systems in light of the development of information and communications technology

In this research project, the following three results have mainly been achieved by constructing economic models that describe the Japanese distribution systems. Firstly, I investigate the problem concerning the choice of desirable distribution channels for a general manufacturer, identifying the economic environment where the manufacturer should vertically integrate a retailer, that where the manufacturer should employ a direct channel. Secondly, I examine the role of a transfer price, which can be regarded as a wholesale price in a divisionalized firm, revealing which type of transfer prices the firm should use in a specific economic environment. Finally, with reference to international distribution systems, I identify the economic environment where parallel trade should be permitted to enhance social welfare. These results have been published in international academic journals and presented at international academic conferences.
