A period of higher short-run price volatility

Robert Shiller writing for the New York Times:

Could the more extreme recent shift mean that home prices will just keep rising this time?

For a home buyer who borrows 90 percent of the money to acquire a house, an appreciation rate of 11.2 percent offers an investment bonanza. By putting a small amount of money down, investors stand to make a large gain if home prices climb. That is the power of leveraging. Recently, however, home buyers have also experienced the unpleasant consequences of leverage when home prices fall. Investing in a home during the wild past few years has been like gambling in a casino: You can leave with riches or empty pockets.

At the moment, it appears that the extreme ups and downs of the housing market have turned many Americans into housing speculators. Many people are still playing a leverage game, watching various economic indicators as well as the state of federal bailout programs […] in an effort to time their home-buying decisions.
