Global supply chain (GSC) trade results from decisions by firms producing final goods to allocate underlying tasks to dedicated facilities in different countries. These decisions create cross-border flows of products at various stages of completion. We demonstrate a divide-and-conquer approach to integrating GSC and computable general equilibrium (CGE) models: the models are solved separately and information is passed between them. A stylized integrated model suggests that by providing low-skilled jobs in developing countries, GSC trade accelerates the transfer of labour out of low-marginal-productivity agriculture in these countries into higher-marginal-productivity manufacturing. At the same time, GSC trade can leave high-income countries having to transfer considerable fractions of their workforce out of manufacturing and into services. After potentially expensive structural adjustment, high-income countries may be left in the long run with no more than a small equilibrium welfare gain or even a loss.
