Shocked by COVID: exporting along global value chains
CEPR
2025.05.21
This paper examines the impact of protectionist policies on exports within global value chains (GVCs), using the COVID-19 pandemic as a natural experiment. Leveraging UK customs data (2017?2020) and a shift-share identification strategy, we estimate an elasticity of exports with respect to intermediate imports of 0.4. A one standard-deviation increase in COVID restrictions in sourcing countries led to a 3.7% decline in intermediate exports. These findings reveal a paradox: policies aimed at self-sufficiency can harm export performance by disrupting supply chains. The study highlights the vulnerabilities of GVCs and the unintended consequences of protectionist trade policies, offering insights into the trade-offs between resilience and open trade networks.
