The characteristics of macroeconomic shocks in the CFA Franc Zone

In this paper we fit a vector error correction model (VECM) in output and prices to data from 10 countries of the CFA Franc Zone. This model allows for various cross-couutry interactions ill both Hie short run and the long run. The VECM parameters are used to estimate persistence profiles of different kinds, in order to identify the degree of homogeneity in the way in which the countries respond to macroeconomic shocks. In this way we call shed light oil questions about the likely size of the costs incurred from these countries' membership of a monetary union.
