This is a very interesting Blog from The WSJ.
On the Economix blog, Ed Glaeser says even hindsight isn’t 20-20 when it comes to housing. “At this point, not only is our foresight limited but our hindsight isn’t exactly 20-20 either. The housing price volatility of the last six years has been so extreme that it confounds conventional economic explanations. Over a four-year period — from February 2002 to February 2006 — the Case-Shiller index increased 68 percent in nominal terms or about 50 percent in constant dollars. Certainly, those price increases cannot be explained by increases in average income. Income growth was quite modest from 2002 to 2006. Nor can the boom be explained by a dearth of new housing supply. Construction rose dramatically during the boom, and we built hundreds of thousands of additional homes. Our current low levels of construction will continue until we work through all of this extra housing stock. “
