Abstract
This paper presents evidence of the stochastic discount factor approach to international risk-sharing applied to fixed exchange rate regimes. We calculate risk-sharing indices for two episodes of fixed or very rigid exchange rates: the Eurozone before and after the introduction of the Euro, and several emerging economies in the period 1993-2005. This approach suggests almost perfect bilateral risk-sharing among all countries from the Eurozone. Moreover, it implies that emerging markets with fixed/rigid nominal exchange rates against the US dollar in the period achieved almost perfect risk-sharing with the US. We conclude that risk-sharing measures crucially depend on the behavior of the nominal exchange rate, implying almost perfect risk-sharing among countries with fixed/rigid nominal exchange rates. Second, a counterintuitive ranking of the risk-sharing levels under different nominal exchange rate regimes suggests a limited use of this approach for cross-country risk-sharing comparisons. Real exchange rates might be very smooth, but risk-sharing across countries is not necessarily perfect.International Risk-Sharing, Stochastic Discount Factor, Fixed Exchange Rates, Exchange Rate Regimes
