I don't think we'll attain the growth rates the CBO is forecasting -- an average of 3.6% from 2013 to 2016 is a lot to ask for (especially if there is substantial deficit reduction over that time period). But even the CBO's optimistic estimates imply we won't fully recover until 2017. And if growth is a bit slower, well, yikes!:
Lots of ground to cover: An update, David Altig: ...There are two pieces of information that emphasize the economy's recent weakness and potential slow growth going forward. The first is this week's revised forecasts and potential for gross domestic product (GDP) from the Congressional Budget Office (CBO), and the second is today's revision of second quarter GDP from the U.S. Bureau of Economic Analysis (BEA). Though estimates of potential GDP have not greatly changed, the CBO's downgrade in forecasts and BEA's report of much lower than potential growth in the second quarter have the current and prospective rates of resource utilization lower than when macroblog covered the issue just about a month ago.
Key to the CBO's estimates is a reasonably good outlook for GDP growth after we get past 2012:
"For the 2013–2016 period, CBO projects that real GDP will grow by an average of 3.6 percent a year, considerably faster than potential output. That growth will bring the economy to a high rate of resource use (that is, completely close the gap between the economy's actual and potential output) by 2017."
The margin for slippage, though, is not great. Assuming that GDP ends 2011 having grown by about 2.3 percent—as projected by the CBO—here's a look at gaps between actual and potential GDP for different, seemingly plausible growth rates:
Attaining 3.5 percent growth by next year moves the CBO's date for closing the output gap up by about a year. On the other hand, a fall in output growth to an average of 3 percent per year moves the date for eliminating resource slack back to 2020. If growth remains below that—well, let's hope it doesn't.
Maybe policymakers should do something to try and improve the odds?
