Outline of Final Research Achievements

Government bonds not only serve as debt but also play a role in facilitating financial intermediation as safe assets (collateral) based on the creditworthiness of the country. In this project, we first theoretically elucidated the role of government bonds as safe assets. Furthermore, as the outstanding government bond balances of advanced countries continue to increase, there are signs of changes in the international capital flows that have made this possible. These issues are difficult to resolve through the policies of individual countries alone. Therefore, we also presented a possible framework for international policy coordination. Additionally, we clarified how such policies should be announced and communicated.

Academic Significance and Societal Importance of the Research Achievements

先進国(特に、日本)では、債務残高が歴史的にみても非常に高い水準にあり、これをどのように削減していくかが、政策の大きな関心事項となっている。将来、なんらかの財政再建は不可避であるが、債務残高をどこまで削減していくべきなのか、といった点については明らかになっていない。本研究プロジェクトは、最適な債務残高がどのような要因に左右されて決定されるかを示したという点で、学術的な意義のみならず、その政策へのインプリケーションの大きさから、社会的意義も大きいと考えている。
