Nonetheless, the Fed and ECB actions sent three messages that should have given the markets pause. First, they were saying that previous actions have not worked; indeed, the major central banks deserve much of the blame for the crisis. But their ability to undo their mistakes is limited.
Second, the Fed’s announcement that it will keep interest rates at extraordinarily low levels through mid-2015 implied that it does not expect recovery anytime soon. That should be a warning for Europe, whose economy is now far weaker than America’s.
Finally, the Fed and the ECB were saying that markets will not quickly restore full employment on their own. A stimulus is needed. That should serve as a rejoinder to those in Europe and America who are calling for just the opposite – further austerity.
But the stimulus that is needed – on both sides of the Atlantic – is a fiscal stimulus. Monetary policy has proven ineffective, and more of it is unlikely to return the economy to sustainable growth.
