| Outline of Final Research Achievements |
This study aimed to unravel the "retirement consumption puzzle," the decline in consumption observed at retirement, and was tested using long-term household panel data from Japan. In addition to factors that can be explained by life-cycle models, behavioral economic factors were also analyzed. In addition, a natural experiment using the Great East Japan Earthquake revealed the impact of economic disadvantage on marital relationships and the redistribution of resources within households. This study advances the integration of life-cycle and behavioral economic models and provides new theoretical predictions.

本研究は、退職時に消費が減少する「退職消費パズル」の理由を明らかにすることを目的としている。標準的なライフサイクルモデルと行動経済学モデルを統合し、日本の長期家計パネルデータを用いて分析を行った。結果として、仕事に関連する支出の減少や予期せぬショックなど、多岐にわたる要因が退職後の消費低下に影響を及ぼしていることが確認された。この研究は、高齢者の生活水準の変化を理解し、将来の政策策定に貢献する学術的・社会的な意義が大きい。
