Central Bank Communication & Monetary Policy

An interesting survey article by Blinder, Ehrmann, Fratzscher, De Haan and Jansen that appeared in the Journal of Economic Literature of December 2008 talks about how central bank communication has been shown to be an important component of the monetary policy toolbox:
Over the last two decades, communication has become an increasingly important aspect of monetary policy. These real-world developments have spawned a huge new scholarly literature on central bank communication—mostly empirical, and almost all of it written in this decade. We survey this ever-growing literature. The evidence suggests that communication can be an important and powerful part of the central bank’s toolkit since it has the ability to move financial markets, to enhance the predictability of monetary policy decisions, and potentially to help achieve central banks’ macroeconomic objectives. However, the large variation in communication strategies across central banks suggests that a consensus has yet to emerge on what constitutes an optimal communication strategy.
