Implications of Monetary Union for Catching-up Member States

We examine the implications of monetary union for macroeconomic stabilization in catching-up participating countries. We allow member states’ supply conditions to differ, especially with regard to sectoral characteristics. Sectoral productivity shocks of the type associated with the Balassa–Samuelson effect tend to hamper the stabilization properties of a currency union. In the face of aggregate supply disturbances, the stabilization costs of renouncing monetary autonomy diminish with a steeper supply curve (as induced by higher trade openness) and—barring idiosyncratic shocks—with a larger reference country size, more homogeneous supply slopes and a higher preference for price stability.
