| Outline of Final Research Achievements |
This study conducted three causal inferences on the impact of natural disasters for the wholesale prices of fishery resources. Initially, the specific natural disaster considered was the leakage of radioactive materials caused by the Great East Japan Earthquake. However, the COVID-19 pandemic that occurred in 2020 was newly added as a "natural disaster" for treatment. Additionally, the third factor examined was the marine release of ALPS-treated water resulting from the decontamination work at the Fukushima Daiichi Nuclear Power Plant in the summer of 2023. While a clear impact was not necessarily identified in all cases, the most significant impact was observed during the first state of emergency due to COVID-19.

| Academic Significance and Societal Importance of the Research Achievements |
これまで自然災害の影響に関する経済学の研究は、水害や地震による不動産価値形成に与える影響を分析するものが多かった。影響が受ける期間を鑑みれば、農業・水産業へのインパクトを正確に評価することは重要な意義を持つ。Tajima et al. (2016)によれば、福島県産の野菜の卸売価格への影響は事故から５年以上を経た後も一部で拡大しており、風評被害と呼べる状況が続いていることを指摘している。現状では、自然資源、とりわけ農産物及び漁業資源へのインパクトを評価した研究は極めて限られていることを考慮すれば、本研究は数少ない評価事例として意義があると考える。
