From the WSJ:

Economists expect Thursday’s GDP report from the Commerce Department will show the economy grew at a 2.7% annual rate in the third quarter. That would still leave economic output 6.7% below what the Congressional Budget Office estimates its potential is.  In other words, in a world where employment and economic activity were as high as they could be without the economy running into inflationary trouble, the U.S. would be producing about $900 billion more in goods and services a year than it is now.

Would it have been 2.7% without QE1 and 2?
