The China Shock
Autor, Dorn, and Hanson's empirical demonstration that Chinese import competition produced persistent, decades-long damage to the local labor markets most exposed to it — the research that transformed economists' understanding of how transitions actually unfold, and the template for understanding AI's geographic effects.
The China shock is the body of empirical research, led by Autor with David Dorn and Gordon Hanson, documenting the labor-market effects of China's entry into the World Trade Organization in 2001. The research tracked the US communities most exposed to Chinese import competition and found effects dramatically worse than standard trade models had predicted. Manufacturing employment collapsed in exposed regions; displaced workers did not move to other areas or retrain into new industries; wages fell, marriage rates declined, deaths of despair rose, and local economies entered cascades of decline that persisted for decades. The research shattered the assumption that labor markets adjust smoothly to trade shocks and established the empirical basis for taking transition costs seriously. For AI, the China shock serves as a warning: major technological or economic shocks can produce persistent damage to specific populations and places even when aggregate effects are positive.
