The four states where investors contributed the most to housing price increases during the housing boom were California, Nevada, Florida and Arizona. As a result, these states had some of the highest rates of housing price increase during the boom. They are also expected to suffer more than other states as a result of the current wave of housing price declines.

Is it possible to measure the relative impact of the housing bust on a state versus the nation as a whole?

Economic theory says that one of the first areas to suffer as the economy weakens is spending on durable goods. 'Durable goods' are goods that last a long time -- think big ticket items like autos, where the purchase represents a significant commitment of finances. When the economy weakens, durable good purchases are expected to react first, because they are more expensive and they are easier to delay due to their longer life.

One of the ways economists track durable goods is to watch auto sales, because sales data for autos is available nationally and by state. The volume of auto sales is estimated nationally based on a survey of retailers. But these surveys are not conducted on a state level. In states like Arizona, information on auto sales is collected as a result of the state sales tax. Even though these two measures are not precisely comparable, taken together they do illustrate broad trends.

In Arizona auto sales have been flat or negative since December 2006. Year to date through September 2007 sales were down 6.2 percent compared to the same period last year. In contrast, national auto sales are actually doing better than last year -- up 2.6 percent for the year through September.

When auto sales are subtracted from total retail sales, Arizona shows an increase of 3.6 percent year to date, a period when retail minus auto nationally showed a 4.0 percent increase. Retail sales growth in Arizona typically outpaces sales activity for the nation as a whole by a significant margin, due to our greater population growth. This past year, however, while Arizona absorbed the shock of the housing downturn, auto sales are fared much worse than the national average, while non auto sales simply slowed to the national average.

The housing bust hit incomes because people can no longer refinance their homes. People working in real estate and real estate related areas saw their earnings drop, and investors watched income from real estate related investments evaporate. The sign on the street that people are in pain is fewer new cars. It appears that the impact of the housing bust on Arizona is greater than the national average, particularly with regard to durables like autos.
