| Outline of Final Research Achievements |
To summarize the research achievements during the funding period, on Project 1 ``Instability of intermediated and intermediation mode," I developed thepretical models that enable us to analyze: the endogenous formation of market structure from the perspective of the selection of intermediation modes; the conditions under which instability occurs, in particular the mechanism by which reputation substitutes for intermediary skills; the relationship between the emergence and collapse of reputation mechanisms in a platform, and the frequency and scale of such instabilities. On Project 2: ``Information overload and the intermediated market that induces search addiction,'' I analyzed the mechanisms by which excessive search occurs on platforms, its efficiency property, and the relationship between sales constraints and price mechanisms in intermediated search markets.

| Academic Significance and Societal Importance of the Research Achievements |
取引仲介の理論として、レモンの市場における評判や市場の不安定性、また、サーチ市場を効率化する副産物としての情報過多やサーチ中毒を明示的に考慮したモデルは、既存研究では今のところ開発されておらず、本研究は学術的意義を有している。現実には、取引仲介という経済行為には必ずしも好意的に受け取られない帰結が伴う。さらに、これら諸問題は取引仲介の技術革新によって深刻化するケースも多い。このような問題意識からモノやサービスの仲介についての経済分析を行うことで、なぜこうした現象が起こるのか、それは政策介入が必要なものなのか、もし必要だとしたらどのような政策がベストであろうかを考えている点で社会的意義がある。
