In the case of the United States, the level of real GDP has reached its pre-crisis peak, but it took three years to do so. In the United Kingdom and the major continental economies, levels of real GDP remain well below their peaks of three or so years ago. In some other cases in Europe the declines are larger and, in fact, are continuing.
In all these cases the level of output remains well below what policy-makers would regard as their respective economies’ “potential” level. A corollary of that is the rate of unemployment in most cases remains unusually high after a year or more of recovery.
