Overall home sales have fallen a remarkable 33 percent since the summer of 2005. Home prices, on the other hand, continued to rise until 2006 and are now only 5 to 10 percent below where they were in mid-2005, according to various measures.
In most other areas of the economy, this combination of plummeting sales and stable prices would not happen. When demand for airline tickets drops, the airlines cut their prices until they have sold their seats. When stocks become less appealing, share prices fall, sometimes sharply.
People are not dispassionate investors, especially when it comes to their homes, and are obsessed with at least breaking even.
