Cases
Nine research findings, measured again on the trade network
Each case takes a paper’s finding or scenario, rebuilds it on UN Comtrade records and gives you a scenario to move: cut a supplier, close a route, add a tariff.

Case 1
Lockdowns travel along supply chains
How much of the 2020 trade collapse came from lockdowns abroad rather than from demand, and through which flows?
Case 2
After Japan's 2011 quake, buyers switched suppliers
After the earthquake, did buyers of Japanese car parts and electronics bring production home, move it nearby, or switch suppliers?
Case 3
Trade is splitting into blocs, with connectors between
Is trade splitting along geopolitical lines, and are “connector” economies bridging the blocs or just relabelling Chinese goods?
Case 4
Europe could replace most of its Russian gas
Could Europe replace Russian gas, and who paid for it elsewhere?
Case 5
Closing Hormuz cut Asia's crude from the Gulf
Who depends on goods that pass the Strait, and what did the 2026 closure change?
Case 6
Rare-earth controls bite hard but briefly
How exposed are magnet and motor makers to China's controls, and who could supply instead?
Case 7
A chip shortage costs several times its size
Why does a chip shortage hurt more than its size, and how did controls reshape the trade?
Case 8
Chinese exports ran ahead of the tariffs, then around them
How did Chinese exports and US imports move around the 2025 tariffs, month by month?
Case 9
Concentrated stages are where supply breaks first
Which traded goods, and which economies' import baskets, are most fragile to a supply shock?
