This article first considers why central European countries wish to join EMU soon. The main reasons are the risk of macroeconomic instability they face outside the euro zone if they wish to grow quickly. At the same time, central Europe is highly integrated with regard to trade with EMU, so it is little exposed to asymmetric shocks that would require a realignment of exchange rates. Finally, it is argued that there is no cost in terms of slower growth from EMU accession, so that there is no trade-off, as has been claimed, between nominal convergence to EMU and real convergence to EU average GDP levels. Second, the article assesses whether central European accession to EMU would be disadvantageous to current members. It concludes that accession cannot increase inflationary pressure on existing EMU members, also as claimed, but that slow growing members of EMU might suffer increased unemployment, unless they increase the flexibility of their labour markets. Incumbent members may also be unwilling to share power with central Europeans in EMU institutions.
