Outline of Final Research Achievements

It has long been an open question whether any Pareto-efficienct and strategy-proof allocation mechanisms are dictatorial in economies with many agents while the dictatorship result in two-agent economies is well known. This is what I tried to clarify in this research. I showed that any Pareto-efficient and strategy-proof allocation mechanisms are alternately dictatorial. This result implies that Pareto efficiency and strategy-proofness are incompatible properties of allocation mechanisms even in many-agent economies.

Academic Significance and Societal Importance of the Research Achievements

社会の構成員に財を配分することは、経済の最も根源的な行為でり、どのような配分メカニズムにより、どのような配分が可能になるかという事は、きわめて重要な問題である。これまで、消費者が2人の場合の配分メカニズムは十分に研究がなされ最適性と耐戦略性が両立し難い性質であることはよく知られていたが、それが多人数の場合にもいえるのかどうかは永らく未解決であった。当研究がはじめて多人数経済であっても最適性と耐戦略性は両立し得ないことを明らかにした。
