At one extreme would be a central bank that is completely rules-based. There will be no room to maneuver and the reaction function would be clear for everyone. There would not be any need for speeches. At the other extreme would be a Fed that does not communicate any intentions or communicates regularly but in a inconsistent manner. A variation on this theme would be a Fed that does to have creditability.
We believe that there are a number of descriptions for who the Fed is trying to be. These are sometimes in the form a metaphor for their behavior. Unfortunately, the description of the Fed at different times may be in conflict. Hence, it is not clear what their behavior will be at any particular time when there are multiple descriptors.
