This is a condensed version of the original article.
The Federal Reserve is not formally inflation targeting. Nevertheless, it is commonly believed to be an implicit inflation targeter. The evolution to inflation targeting occurred because central banks, most importantly the Federal Reserve, demonstrated that monetary policy could control inflation. As central banks’ credibility for keeping inflation low increased, policy actions became increasingly focused on affecting the growth rate of employment or the unemployment rate. The author argues that this change in emphasis is unlikely to generate positive benefits; more importantly, it endangers the continued effectiveness, and perhaps even the viability, of inflation targeting.
