For fun … tomorrow is the tenth anniversary of then Fed Chairman Alan Greenspan’s “Froth” testimony on June 9, 2005:
Although a “bubble” in home prices for the nation as a whole does not appear likely, there do appear to be, at a minimum, signs of froth in some local markets where home prices seem to have risen to unsustainable levels.
The housing market in the United States is quite heterogeneous, and it does not have the capacity to move excesses easily from one area to another. Instead, we have a collection of only loosely connected local markets. Thus, while investors can arbitrage the price of a commodity such as aluminium between Portland, Maine, and Portland, Oregon, they cannot do that with home prices because they cannot move the houses. As a consequence, unlike the behaviour of commodity prices, which varies little from place to place, the behaviour of home prices varies widely across the nation.
Speculation in homes is largely local, especially for owner-occupied residences. For homeowners to realise accumulated capital gains on a residence–a precondition of a speculative market–they must move. Another formidable barrier to the emergence of speculative activity in housing markets is that home sales involve significant commissions and closing costs, which average in the neighbourhood of 10 per cent of the sales price. Where homeowner sales predominate, speculative turnover of homes is difficult.
But in recent years, the pace of turnover of existing homes has quickened. It appears that a substantial part of the acceleration in turnover reflects the purchase of second homes–either for investment or vacation purposes. Transactions in second homes, of course, are not restrained by the same forces that restrict the purchases or sales of primary residences–an individual can sell without having to move. This suggests that speculative activity may have had a greater role in generating the recent price increases than it has customarily had in the past.
The apparent froth in housing markets may have spilled over into mortgage markets. The dramatic increase in the prevalence of interest-only loans, as well as the introduction of other relatively exotic forms of adjustable-rate mortgages, are developments of particular concern. To be sure, these financing vehicles have their appropriate uses. But to the extent that some households may be employing these instruments to purchase a home that would otherwise be unaffordable, their use is beginning to add to the pressures in the marketplace.
The U.S. economy has weathered such episodes before without experiencing significant declines in the national average level of home prices. In part, this is explained by an underlying uptrend in home prices. Because of the degree of customisation of homes, it is difficult to achieve significant productivity gains in residential building despite the ongoing technological advances in other areas of our economy. As a result, productivity gains in residential construction have lagged behind the average productivity increases in the United States for many decades. This shortfall has been one of the reasons that house prices have consistently outpaced the general price level for many decades.
Although we certainly cannot rule out home price declines, especially in some local markets, these declines, were they to occur, likely would not have substantial macroeconomic implications.
Yes. Maybe a little “froth” in housing, but no “substantial macroeconomic implications”! Oops …
