🚨Job Market 2025-26🚨 ⛴️🌪️How vulnerable is transportation and global trade to extreme weather? My JMP studies how tropical cyclones disrupt maritime transportation, and how private adaptation shapes welfare and investment under climate change. 🧵 A JMP thread (link below)

Thank you @kielinstitute! I am glad to participate to the Kiel Trade Talks -- see you on Friday!

Thank you @DSE_Unibo for the support! Here is my job market paper thread with more details 👇 🔗

🏗️ Policy takeaway? I derive first-order welfare gains from port capacity = a guide for future port-investment allocation. Ignoring future weather risk / adaptation causes investment misallocation (up to 50%)! 📸 Global welfare gains to port capacity

🌍 Calibrated globally, under unmitigated climate change: Rerouting absorbs most welfare losses = a key private adaptation margin! 📸 Counterfactual weather at ports and welfare change with rerouting

💡 But rerouting has costs: it creates congestion spillovers! ⚙️To capture these effects, I build a model of production networks where firms choose least-cost routes across congested, weather-exposed ports. 📸 Congestion forces rationalize well maritime traffic data

🔁 Firms reroute shipments to avoid exposed ports, especially the first time they face a cyclone. Yet, buyer-supplier links survive: adaptation happens through routing, not sourcing. 📸 Probability of using the exposed port (firm-to-firm)

⚡ When cyclones hit, ports shut down for safety (1–2 weeks). Activity rebounds quickly once winds drop, but the shock triggers adjustments far beyond the port itself. 📸 Temporary drop in the probability that the port operates

🌪️ I combine Brazilian firm-to-firm shipment data (2014–2023) with daily port operations and tropical cyclone tracks. This gives me a high-frequency, global view of how weather shocks hit transportation and how firms respond in real time. 📸 Tropical cyclone tracks (2014–2023)

I am honoured to have participated in the GEP/CEPR PhD Conference at @UoN_GEP and to have received the Best Paper Award. I extend my congratulations to @cespinosad for sharing the award, and my sincere thanks to the organizers for hosting such an outstanding conference!

I often hear Americans & rich brits justify buying oversized, polluting vehicles by claiming they need them because they live in the "countryside". I call bullshit, Ladies and Gentlemen, allow me to introduce, the Citroen C15⬇
