Just How Bad Will It Get?

Via Brad DeLong, Menzie Chinn compares the CBO's February and March projections of economic disaster and notes that they've become considerably more disastrous in only a month:

Notice that the no-stimulus counterfactual output gap and unemployment rates are noticeably worse now than only a month ago (see this post). For 2010, the February counterfactual was -6.3% of GDP, now around -10%; the February counterfactual for 2010 was 8.7% unemployment, now it's nearly 11% (I'm eyeballing the current counterfactuals off of Figures 2-1 and 2-2)....My guess is that that "massive" stimulus is going to look a lot less "massive" given the severity and duration of this recession.

A month ago CBO estimated that unemployment would hit 8.7% in the absence of a stimulus package.  Now they think it would have been around 10.5%.  With the stimulus, they think it will top out at a little over 9%.
