Some may call this news, but I would call it common sense. The lesson learned here applies a lot more broadly than just to the city of Seattle.

An intriguing new analysis by a University of Washington economics professor argues that home prices have, perhaps inadvertently, been driven up $200,000 by good intentions.

Between 1989 and 2006, the median inflation-adjusted price of a Seattle house rose from $221,000 to $447,800. Fully $200,000 of that increase was the result of land-use regulations, says Theo Eicher — twice the financial impact that regulation has had on other major U.S. cities.

"In a nationwide study, it can be shown that Seattle is one of the most regulated cities and a city whose housing prices are profoundly influenced by regulations," he says.
