Outline of Final Research Achievements

In this research, we build a New Keynesian model with banks and investigate the infuence of possible bank default and bank leverage constraints on monetary and macroprudential policy prescriptions. We find that a macroprudential policy that limits bank leverage reduces the risk of bank default and improves long-run welfare. In the short run, a macroprudential-flavored" monetary policy can reduce financial propagation by affecting bank shadow values, while countercyclical capital regulation is effective for stabilizing bank leverage. Our study shows that introducing countercyclicality to bank capital regulation achieves little welfare improvement if monetary policy is already used to mitigate financial acceleration. The jointly optimal policies suggest that policymakers assign countercyclical macroprudential roles to monetary policy, and bank capital regulation should focus on the desired level of prudence.

Academic Significance and Societal Importance of the Research Achievements

本研究では比較的シンプルなモデルにおいて金融政策とマクロプルーデンス政策の効果を同時にシミュレートする枠組みを提供するとともに、シミュレーションにおいて一定の政策インプリケーションを得た。当然シミュレーションの結果はモデルの様々な仮定に依存するものであり、そのまま現実の政策に当てはめることはできないが、金融政策がプルーデンス政策の役割も果たしうる可能性や、プルーデンス政策が景気変動の安定化よりも、むしろ経済状態に依らない一定のプルーデンスの達成に向いている可能性に関しては、一定の示唆がある。今後異なる設定で同様のシミュレーションを行っていくような研究につながっていくものと考える。
