Abstract:
We examine real business cycle convergence for 41 euro area regions and 48 US states.Results obtained by a panel model with spatial correlation indicate that the relevance ofcommon business cycle factors is rather stable over the past two decades in the euro area andthe US. Ongoing business cycle convergence often detected in cross-country data is notconfirmed at the regional level. The degree of synchronization across the euro area is similarto that to be found for the US states. Thus, the lack of convergence does not seem to be animpediment to a common monetary policy.
