| Outline of Final Research Achievements |
The project has elucidated some key features such as network governance, heterogeneity and diversity in demand, big data and freemium pricing, by examining some platform businesses (called a two-sided market) with innovation and network externality such as telecommunication and game software in Japan. Also, it has developed theoretical models with an application to dynamic model, which included those additional characteristics as well as network externality and innovation.
Based on the theoretical and empirical analyses, we have examined necessary enforcement of competition policy toward two-sided markets, and also existing policies enforced in US, EU and Japan. Finally, the relation between a two-sided market and small and medium-sized firms, and mobility (entry and growth) in market structure of a two-sided market have been analyzed as well.
