The enlargement of the European monetary union to include the accession countries (ACs) will not lead to higher average inflation in the enlarged euro area, but only to inflation redistribution across countries if continuity of the monetary policy framework is preserved. In the short term,...

It is commonly thought that an open economy can accommodate output shocks through either exchange rate or real sector adjustments. We formalise this notion by incorporating labour market rigidities into an “escape clause” model of currency crises. We show that the absence of structural...
