In the long run, does it matter whether a policy action was anticipated or not?

What will be an ideal response?

ANSWER

In the long run, output is potential output. The response to an anticipated policy action comes sooner, but is ultimately no different than the delayed response to a “recognized” policy. Nonetheless, it does matter whether or not the policy had been anticipated, because anticipated policies are less destabilizing to output.
