People thought it was good news a few years back when housing starts – the supply side of the picture – were running about two million annually. But household formations – the demand side – only amounted to about 1.2 million. After a few years of such imbalances, the country unsurprisingly ended up with far too many houses.
There were three ways to cure this overhang: (1) blow up a lot of houses, a tactic similar to the destruction of autos that occurred with the “cash-for-clunkers” program; (2) speed up household formations by, say, encouraging teenagers to cohabitate, a program not likely to suffer from a lack of volunteers or; (3) reduce new housing starts to a number far below the rate of household formations.
