Business Cycle Synchronisation: Disentangling Trade and Financial Linkages

Drawing on a large cross-section of countries, this paper explores whether closer economic ties between countries foster business cycle synchronisation and disentangles the role of the various channels, including trade and financial linkages as well as the similarity in sectoral specialisation. Our results confirm that output comovement is higher for country pairs with closer trade linkages and similar patterns of sectoral specialisation. By contrast, it remains difficult to find a direct relationship between bilateral financial linkages and output correlation. However, our results suggest that financial integration spurs business cycle synchronisation indirectly by raising the similarity in sectoral specialisation. Notably, the main findings hold regardless of whether financial linkages are captured in terms of FDI or portfolio holdings.
