Stephen Roach of Yale University, here, points out that the rate of growth in personal consumption is just 25% of what it used to be:
Over the 21 quarters since the beginning of 2008, real (inflation-adjusted) personal consumption has risen at an average annual rate of just 0.9%. That is by far the most protracted period of weakness in real US consumer demand since the end of World War II – and a massive slowdown from the pre-crisis pace of 3.6% annual real consumption growth from 1996 to 2007. ...
[T]he release of pent-up demand in the current cycle amounted to just 3% annualized growth in the five quarters from early 2010 to early 2011. Moreover, the strongest quarterly gain was a 4.1% increase in the fourth quarter of 2010.
This is a stunning result. The worst consumer recession in modern history, featuring a record collapse in durable-goods expenditures in 2008-2009, should have triggered an outsize surge of pent-up demand. Yet it did anything but that. Instead, the release of pent-up consumer demand was literally half that of previous business cycles.
