Changes in behaviour under EMU

Using a simple model of the euro area economy, we explore whether EMU has been associated with changes in behaviour both in the run up to Stage 3 and since it started operating. We find that some behaviour has indeed changed; expectations formation, inflation, country dispersion of behaviour, fiscal policy (although the run up to Stage 3 shows a greater change than within it) and monetary policy (with several caveats). However, EMU does not appear to be associated with changes in the labour markets; employment, output growth and productivity. Substantial caution is needed in attributing these changes to EMU as much of the rest of OECD enjoyed similar changes over the same period.
