A Neoclassical Model of the World Financial Cycle
Emerging markets face large and persistent fluctuations in sovereign spreads. To what extent are these fluctuations driven by local shocks versus financial conditions in advanced economies? To answer this question, we develop a neoclassical business cycle model of a world economy with an advanced country, the North, and many emerging market economies, the South. Northern households invest in domestic stocks, domestic defaultable bonds, and international sovereign debt. Over the 2008-2016 period, the global cycle phase, the North accounts for 68% of Southern spreads’ fluctuations. Over the ...

In Search of Dominant Drivers of the Real Exchange Rate
We uncover the major drivers of macro aggregates and the real exchange rate at business cycle frequencies in Group of Seven countries. The estimated main drivers of key macro variables resemble each other and account for a modest fraction of the real exchange rate variances. Dominant drivers of the real exchange rate are orthogonal to main drivers of business cycles, generate a significant deviation of the uncovered interest parity condition, and lead to small movements in net exports. We use these facts to evaluate international business cycle models accounting for the dynamics of both macro ...

Trade in Commodities and Business Cycle Volatility
This paper studies the role of differences in the patterns of production and international trade on the business cycle volatility of emerging and developed economies. We study a multi-sector small open economy in which firms produce and trade commodities and manufactures. We estimate the model to match key cross-sectional and time-series differences across countries. Emerging economies run trade surpluses in commodities and trade deficits in manufactures, while sectoral trade flows are balanced in developed economies. We find that these differences amplify the response of emerging economies ...
