The tress of having a single monetary policy in Europe

This paper estimates forward-looking Taylor rules for the euro area. Using the asymmetries in inflation and cyclical output developments across countries, we investigate the adequacy of the single monetary policy for each of the EuropeanMonetary Union (EMU) member countries. Notable differences emerge across the countries. Taking a euro area perspective, we also show that it depends upon the underlying country weighting scheme in the monetary decision process of the ECB whether or not there has been a synchronisation of business and inflation cycles among the EMU member countries over the years. Finally, we produce an estimate of the actual policy weights the ECB has implicitly attached to each of the member countries. Developments in small member countries have received more than proportional weights in actual monetary policy decisions of the ECB.
