While the Fed doesn't have explicit targets such as we have, the basic objective of every central bank is to keep the economy operating reasonably close to potential and to hold inflation at very low levels. That's essentially the game we're in.
Going back to your previous question, that becomes much easier to do, from the standpoint of monetary policy, if the economy is very flexible and adjustments can take place. While we've had a lot of success, as Mr. McCallum pointed out, over the last decade, a lot of that success is not due to absolute brilliance on the part of the Bank of Canada but is due to the fact that a lot of Canadians worked very hard to make this economy more flexible over that period. This doesn't mean life is easy, but there's been a lot of hard work going on, and that is really the key to success.
