The rise in GDP during the third quarter prompted the Room for Debate blog of the New York Times to ask whether the Obama Administration's $787 billion stimulus plan worked. MIT and Baseline Scenario 's Simon Johnson says the stimulus package worked on both an economic front and a political front (which then led to larger stimulus effects globally). Harvard University Economist Jeffrey Miron says no, look to monetary policy. Russell Roberts , economist at George Mason University, is sekptical of the stimulus plans power and suggests the growth might have occurred without it. And Mark Thoma says that "the stimulus programs in place now are probably too small." Read the full "debate" here . Meanwhile, James Hamilton had one of the most instructive pieces on the GDP numbers at the Econbrowser blog. Hamilton feels very positive about the GDP growth, and he neatly breaks down, and illustrates, the various contributors to the growth: Consumption spending is the biggest component of GDP and the main contributor to third quarter growth, accounting by itself for 2.4 percentage points out of the 3.5% total, and with consumer purchases of motor vehicles and parts alone 3/5 of the contribution of consumption. Next in importance was inventory rebuilding, which added 0.9 percentage points to the total and could make a significant further contribution in the quarters ahead. Housing is finally making a positive rather than a negative contribution, and nonresidential fixed investment was a smaller drag than I had been expecting. Imports grew faster than exports, though I'm relieved that trade overall is coming back. The government sector made a smaller contribution than one might have thought given the fiscal stimulus, in part because lower state and local spending offset some of the increased federal spending. For a healthier long-run growth path I'd prefer to see business fixed investment and net exports adding rather than subtracting. But, compared with what we've been seeing recently, this overall is a quite welcome report. Hamilton and Menzie Chin n track recessions through their Econbrowser Recession Indicator Index --a pattern recognition algorithm for identifying recessions that waits one quarter for data revisions and clear trend identification before making an assessment. With the third quarter GDP numbers out they looked at the revised second quarter figures. And they conclude that the recession did not end during the second quarter. Read the full GDP analysis here .
