Inflation Targets in a Monetary Union with Endogenous Entry

This paper shows that in a monetary union the interest rate rule of the Central Bank should react to the in°ation rate of the Harmonized Index of Consumption Price (HICP) rather than to the inflation rate of the Welfare-Based Consumption Price (WBCP). In a two{country general equilibrium model of the EMU with endogenous entry, we compare both monetary policy regimes and find that targeting the HICP inflation rate reduces the volatility of the Producer Price Index (PPI) in°ation rate and the volatility of the nominal .
