Staff Working Paper No. 1,159
By Richard Baldwin, Rebecca Freeman and Angelos Theodorakopoulos
This paper develops a new toolkit for analysing how global shocks affect the geographical and functional distribution of global value chains (GVCs) at the subnational level. Using the toolkit, which we call the shocks approach to indicator design, we derive a family of GVC indicators that distinguish between import and export‑side GVC exposure, direct (face‑value) and indirect (hidden exposure) linkages, and gross versus value‑added GVC trade flows. Applying the indicators to multi‑regional multi‑country input‑output data and analysing EU‑UK and EU‑China trade, we show that inferences about regional vulnerability depend critically on the type of exposure measured. The results highlight how global disruptions propagate unevenly across regions and provide a foundation for place‑based policies that strengthen resilience through targeted diversification and smarter supply‑chain monitoring.
