Outline of Final Research Achievements |
We consider multi-sided platform competition as allowing participants (consumers and upstream firms) to multi-home. We established a basic model which is tractable and can be applied to further theoretical and empirical research. We focus on the mechanism of vertical restrains and vertical integration between upstream firms and platforms in such markets. Our results sharply contrast with the results of existing literature in which all participants are assumed to single-home or multi-home. We also apply our theoretical results to the real world examples, which include pay-TV market and video game market. These case studies based on our theoretical model help us to obtain policy implications.

Academic Significance and Societal Importance of the Research Achievements |
近年の技術革新に伴う取引のデジタル化は、多くの売り手や買い手が従来よりも低いコストで複数のプラットフォームに参加することを可能にした。その結果、多くの市場において、参加者のプラットフォーム選択は柔軟になり、参加者がマルチホーミングする状況が多く観察されるようになってきた。その一方で、既存の経済理論モデルでは、内生的なマルチホーミングが考慮されてこなかった。本研究で構築した理論モデルは、より現実に近い状況を説明することが可能になり、また、既存理論モデルとは異なる競争メカニズムがあることも明らかになった。これにより、より現実に即した政策的インプリケーションを導くことが可能になった。
