Abstract: I extend the Bayoumi-Eichengreen (1993) approach by extracting new information from a scatter plot of correlation coefficients between shocks in order to better visualize how far a given country is from a monetary union. Indexes of distance and relative strength can be derived from either a nonlinear or a linear combination of correlations in connexion with distinct welfare loss functions. Using quarterly data on ten countries over 1979:I-2011:IV, shocks have become more symmetric within, but also outside, the euro area. Despite less asymmetry in shock asymmetry since 1999, new statistical tests support the idea of a two-speed EMU.
