| Outline of Final Research Achievements |
We heavily rely on digital platform companies in almost every situation. However, we also worry about monopolization by these companies through network externalities. In response to this trend, we propose several analytical frameworks that capture the essence of these platform companies and then theoretically investigate them. Given that some platform companies use algorithmic pricing, we examine the effects of algorithmic personalized pricing on welfare in various competitive environments, including two-sided markets. We clarify the conditions under which such pricing harms consumer welfare. Additionally, because some platform companies utilize customer data to achieve high profitability, we explore market environments where consumers can manage their data in transactions with platform companies. We specify the conditions under which such data management benefits firms and consumers.

プラットフォーム企業への依存度が高まっているが、これら企業による市場独占化への懸念もある。また、データをテコにして事業を拡大している企業が存在する中で、その利活用の影響と規制の在り方も議論されている。このような状況を踏まえて、本研究課題ではプラットフォーム企業による市場集中度が高くなりやすい競争環境を明らかにしつつ、データ利用規制が市場環境に与える影響も明らかにしている。現在注目されているプラットフォーム企業を取り巻く競争政策上の課題に対していくつかの知見をもたらしている点で、学術にとどまらず政策上の貢献もしている。
