Actually, now that I look at the data again, I see that I misstated. The NBER says that the economic peak began in Dec. 2007, and that the economic decline that has happened since then qualifies as a recession. But the BEA says that GDP has actually increased at a 3.2% since then:
So yes, we are in a recession, but the GDP is still increasing at a pretty healthy rate, at least as of the end of the third quarter.
The 2nd quarter bump was the $300 billion stimulus (annualized at 1.2 trillion). That was nothing but borrowing from future GDP.
