Setting aside this logical inconsistency (or is it denial?), there is plenty of precedent for long declines in home prices. Take a look at the chart, below, which shows the Case Shiller home price index for Los Angeles.

Of course, this doesn't mean that we should expect the same course of events for Bay Area home prices. For starters, prices here have already fallen more than 25%. But it does highlight the fact that home prices tend to move in lengthy cycles. We shouldn't assume that they'll quickly adjust to the latest economic news, whether good or bad. And remember, most economists are expecting a long, grinding recovery from the current recession. Why should the housing market do any better?
