This paper studies the relationship between inflation, output, money and interest rates in the euro area, using data spanning 1980 2000. The P* model is shown to have considerable empirical support. Thus, the price gap' or, equivalently, the real money gap' (the gap between current real balances and long-run equilibrium real balances), has substantial predictive power for future inflation. The real money gap contains more information about future inflation than the output gap and the Eurosystem's money-growth indicator (the gap between current M3 growth and a reference value). The results suggest that the Eurosystem's money-growth indicator is an inferior indicator of future inflation.
