Occasionally, inflation is stubborn. For many years it was hard to bring under control, but in the last decade has been low and stable. The latest Geneva Report on the World Economy studies the latest bout of stubbornness, asking why inflation has remained in such a narrow range. It shows that a large number of diverse shocks have hit developed economies during the last decade, which have more or less cancelled each other out. One of these 'shocks' has been monetary policy, which was skilfully used in response to wider macroeconomic events. Central banks, in other words, combined good policies and good luck. Next time, however, we may not be so lucky.
