There is an ongoing debate among economists whether international trade contributes to business cycles synchronisation. So far, causal evidence has been limited. This column presents new research on the role of multinational firms in the transmission of shocks. The authors use a rich firm-level dataset from the US Census Bureau and the 2011 Japanese earthquake/tsunami as a natural experiment. They find that US firms with high dependence on Japanese inputs suffered large output losses following the earthquake. Global supply chains, therefore, play an important role in the cross-country transmission of shocks.
