Tax Changes and the Housing Boom
The good news about this factor is that it gets the timing right for the beginning of the housing boom, unlike the attempt to pin the blame on Greenspan's monetary policy. The bad news, as Mark Brady has pointed out, is that U.S. tax changes can only explain the U.S. housing boom and not the European housing booms. Moreover, it can only explain a boom and not a bubble. A tax change should cause a real appreciation in home values that is permanent (until the exemption is repealed), not self-reversing. But then again, that should help prevent real housing prices from returning to their 1997 level.
