His consistent interest is consensus-building in cumulative culture. Cumulative culture, by its nature, requires expertise in one’s own context when evaluating new works (e.g., peer-review of academic papers, critique of contemporary art). For such expertise-dependent consensus-building, can we (i) discover common laws or features across disciplines (positive analysis), or (ii) define and design “better” mechanisms (normative analysis)? To the former, he modeled the dynamic process of consensus-building, with economic growth theory and cumulative cultural evolution. To the latter, he proposed incentive mechanisms for the consensus-building on citation relationships, with random walks on graphs and peer-prediction methods. These studies are important because the consensus-building in cumulative culture could be a fundamental topic for cultural economics and cultural policy.
伊東の一貫した関心は累積的な文化における合意形成である。累積的な文化はその性質上、新たな作品を評価する際に自身の文脈に関する専門知識を必要とする (e.g., 学術論文の査読, 現代美術の批評)。専門知識に依存するこのような合意形成について (i) 事実解明的分析として分野を超えた共通の法則や特徴を発見したり (ii) 規範的分析として「より良い」制度を定義・設計することは可能なのだろうか。前者に対し、彼は経済成長理論と累積文化進化論を組み合わせて合意形成の動学的なプロセスをモデル化した。また後者に対し、彼はグラフ上のランダムウォークとピア予測法を組み合わせて引用関係の合意形成に用いるインセンティブ・メカニズムを提案した。累積的な文化における合意形成は文化経済学および文化政策の基礎的な主題となりうるため、これらの研究は重要である。
