The green shoots of recovery are growing a little taller. Newly released gross domestic product estimates   measuring consumer and government spending, investments and net exports   show the economy growing at 2 percent in the third quarter, up from 1.3 percent in the second. In normal times, this would be nothing to get excited about; average GDP growth between 1947 and 2012 was 3.25 percent. But we are recovering from a systemic financial crisis, not a routine dip of the business cycle, and in such cases recovery is noticeably more sluggish. Don’t believe Cassandras who suggest the good news is a chimera. We are in  an “L”-shaped recovery rather than a “V”-shaped one, and the fact that GDP is steadily rising is in itself encouraging.
