Audacity of hope budgeting

Mankiw:

Here (in red) are the growth forecasts used to put out the new Obama administration budget, followed by the consensus forecast of a panel of "Blue Chip" private forecasters (in blue, naturally). (Source. Go to Table 3.)

2009: -1.2% -1.9%
2010: +3.2% +2.1%
2011: +4.0% +2.9%
2012: +4.6% +2.9%
2013: +4.2% +2.8%

Accumulating the difference, you find that Team Obama projects about 6 percent higher GDP in 2013 than do private forecasters.

As Frederick the Great would say: "L’audace, l’audace—toujours l’audace!"
