Abstract
This paper studies to what extent the diversity of exchange rate regimes within Mercosur exerts an influence on the feasibility of a monetary union in this area. A semi-structural VAR model is built for each country, including a set of international and domestic variables. Based on impulse response functions and forecast error decomposition, we conclude that differences of exchange rate regime explain significantly the divergences of economic dynamics triggered by foreign or domestic shocks. Second, we decompose the structural innovations generated by each country model into unobservable common and idiosyncratic components, using a state-space model. This last exercise, intended to assess the degree of policy coordination between the Mercosur members, did not disclose any common component for the structural innovations generated by the three national models.
