This paper studies ECB and Bundesbank communication on monetary policy during the first years of the European Economic and Monetary Union. We study whether statements by different (groups of) central bankers have been contradictory and whether differences have diminished over time. We find that...

Business climate indicators are used to receive early signals for turning points in the general business cycle. Therefore methods for the detection of turning points in time series are required. Estimations of slopes of a smooth component in the data can be calculated with local polynomial...
