A central puzzle in international finance is that real exchange rates are volatile and, in stark contradiction to efficient risk-sharing, negatively correlated with relative consumptions across countries. This paper shows that a model with incomplete markets and a low price elasticity of imports...

We decompose the correlation between relative consumption and the real exchange rate into its dynamic components at different frequencies. Using multivariate spectral analysis techniques we show that, at odds with a high degree of risk-sharing, in most OECD countries the dynamic correlation...

Sylvain Leduc notes that the extent of international risk-sharing remains surprisingly small. This appears to be the case even though the development of international financial markets should better equip households to pool their resources so that their level of consumption varies less from year...
