Paul Krugman writes:
Europe’s Gap: a huge gap has opened up between a reasonable estimate of potential output and actual output. Even if you believe that growth in Europe has picked up since the first quarter — and that the pickup will continue — it will take years to close that gap. The only way you could justify not doing more to promote growth is to assume that potential output has been drastically reduced by the crisis — and if you believe that, you should be working day and night to reverse that decline.
The idea that policy has done enough is just crazy.
