Supply chain disruptions: Shocks, links, and hidden exposure
The exposure of US manufacturing to foreign supply chains, especially China, is much larger than previously thought, according to a study using a global input-output database. The study also suggests that the increase in supply chain disruptions in recent years is due to changes in the nature of the shocks, not the supply chains themselves. G7 leaders have expressed concerns about vulnerabilities and non-market policies in supply chains. The study highlights the importance of differentiating between "face value" and "look through" measures when assessing supply chain linkages.

Frequently Asked Questions (FAQ)
FAQ 1: What are the main causes of recent supply chain disruptions?
Answer: Recent supply chain disruptions have been primarily caused by the COVID-19 pandemic and geopolitical events such as the Ukraine-Russia war. The pandemic has affected global supply chains due to lockdowns and labor shortages, while the war has exacerbated already-strained global supply chains and prompted sanctions that have frozen Russian assets abroad.

FAQ 2: How do supply chain disruptions impact the global economy?
Answer: Supply chain disruptions can lead to a shortage of critical goods, increase in prices, and inflation. They exacerbate financial turmoil and affect international trade patterns. Global trade interdependencies mean that a disruption in one part can have far-reaching effects on economic stability and growth. (Sources: IMF, European Parliament)
FAQ 3: What are some strategies to mitigate the negative impacts of supply chain disruptions?
Answer: Strategies to mitigate the negative impacts include diversifying supply sources (multisourcing) to spread risk, improving supply chain visibility, and employing flexible supply chain strategies such as reshoring or nearshoring. There is also a need for better measurement of foreign supply chain exposure to understand vulnerabilities. (Sources: MIT, NBER)
FAQ 4: How has the COVID-19 pandemic uniquely affected supply chains?
Answer: The COVID-19 pandemic has uniquely affected supply chains by causing sudden and widespread disruptions due to factory shutdowns, transportation halts, and sudden shifts in demand for various goods. It challenged the resilience of the global supply chain and revealed hidden exposures and dependencies. (Sources: NCBI, Food Quality and Safety)
FAQ 5: Can supply chain models predict disruptions effectively?
Answer: While existing supply chain models, such as input-output (IO) models, attempt to predict disruptions, they have several drawbacks and may not fully account for complex global interdependencies and the propagation of negative shocks. Newer methodologies and more comprehensive data are needed for better predictions. (Sources: CEPR VoxEU, IMF)
