Is your supply chain resilient to weather fluctuations? How can you quantify this risk exposure?
Extreme weather shocks don’t just affect yields—they reshape global supply chains.
How resilient are those networks?
...
While we focus on ag commodities and international trade, the framework applies broadly to other supply chain networks...
Joint work with Kristiina Ala-Kokko, Shawn Arita, Vincent Breneman, Joseph Cooper, and Grant Gardner; published in the recent special issue of the Agricultural Finance Review on Financing Resilient Food Systems. Link here:

Pest damage isn’t static — it moves in cycles. And so does resilience. The catch? We rarely know which phase we’re in—and the hidden production losses can be substantial. A 🧵 for our new paper in @NatureComms ...
In fact, the erosion phase alone implies massive (often latent) aggregate losses in production, which we quantify in millions(!) of lost food rations.
So the real question isn’t just:
“What is the yield gain from Bt?”
It’s:
“What is the value of staying ahead of resistance?”
Because in agriculture, technology doesn’t just diffuse; it evolves in a biological arms race.

One section of our recent @_Food_Policy review article focuses on #ClimateChange econometrics in agriculture, in which we highlight how the Schlenker–Roberts approach has proven robust across multiple crops, regions, and empirical strategies 🧵
It reveals a clear lineage of applied climate–agriculture econometrics that has grown from this work.
