Keywords: mechanism design, cumulative cultural evolution, blockchain, economic growth

Kensuke ITO is a Ph.D. student in the Graduate School of Interdisciplinary Information Studies at The University of Tokyo, whose main interest is the mechanism design to stimulate cultural accumulation. He has been doing the theoretical research on cumulative cultural evolution that aims to clarify determinants of the accumulation speed of cultural traits. His main contribution to the field is the use of the methodology of economic growth theory in which rational agents try to maximize their utility. In order for a practical application of the proposed theories, he also researches the incentive design behind blockchain technologies. His another recent study intends to extend Bitcoin’s protocol to citation network formation and thereby design a decentralized autonomous reward system which further promotes cultural accumulation.    

伊東の主な関心は、文化の累積を促すメカニズムの設計である。 彼はこれまで文化的形質の蓄積速度の決定要因を明らかにすることを目指す累積的文化進化に関する研究を行ってきた。当分野に対する彼の主な貢献は、合理的なエージェントが効用最大化を試みる経済成長理論の手法を用いたことである。 また、提案した理論を現実に応用すべく、彼はブロックチェーン技術の背後にあるインセンティブ設計に関しても研究を行っている。最近の別の研究では、ビットコインのプロトコルを引用ネットワークの形成へと拡張することで、文化の蓄積をさらに促進する自律分散型報酬システムの設計を志向している。
