Has Monetary Policy Become More Efficient? A Cross-Country Analysis
26 Pages Posted: 8 May 2006
Over the past 20 years, macroeconomic performance has improved in industrialised and developing countries alike. In a broad cross-section of countries inflation volatility has fallen markedly while output variability has either fallen or risen only slightly. This increased stability can be attributed to some combination of more efficient monetary policy making, a reduction in the variability of supply shocks, and changes in the structure of the economy. We develop a method for allocating performance changes among these factors. For 21 of the 24 countries we study, more efficient monetary policy has been the driving force behind improved performance.
