What drives the resilience of international trade against increasingly destructive natural disasters? In this study, I investigate the dynamics and spatial distribution of Hurricane Katrina's trade effects across United States infrastructure and break new ground on the mechanisms underlying the static and dynamic trade resilience. Analyzing port-level data, I find that ports subject to this calamity experience significant and lasting trade reductions, while export and import shipments handled by the adjacent ports exhibit significant increases. Interestingly, the duration of this rerouting effect is persistent for 8 years uncovering novel path dependencies and providing important policy insights in light of recent events.

自然灾害、总体贸易弹性和当地破坏：来自卡特里娜飓风的证据

是什么推动了国际贸易抵御日益严重的自然灾害的能力？在这项研究中，我调查了卡特里娜飓风对美国基础设施贸易影响的动态和空间分布，并在静态和动态贸易弹性的潜在机制上开辟了新天地。分析港口层面的数据，我发现受灾港口的贸易量显着且持久地减少，而相邻港口处理的进出口货物则显着增加。有趣的是，这种重新路由效应的持续时间持续了 8 年，揭示了新的路径依赖关系，并根据最近发生的事件提供了重要的政策见解。
