The impact on central macroeconomic variables from changes in the monetary-policy regime in the OECD countries in the period 1970-2005 is estimated using the difference-in-difference method. We find that both shifts to a fixed-exchange-rate policy and to inflationtargeting have led to a decline in inflation beyond the global trend in the following years. Furthermore, we find a significant reduction in the volatilities in both inflation and output-gap, beyond the global trend, after the adoption of a consistent fixed-exchange-rate policy, while no such effect can be found from a move to inflation targeting. The results are robust to several changes in the classification of the individual countries. In important respects, the results are at odds with recent literature on monetary policy and inflation targeting. This raises some questions: Does the exchange rate in practice absorb or create shocks? Should the role of fiscal policy be reconsidered? Are the concepts of robustness and optimality inadequately mixed? The answers can hopefully be found via future research. Revised December 2007.
