5/15/2011 02:41:00 PM On Friday, Dave Altig asked Just how out of line are house prices?. Dr. Altig's post featured both a price-to-rent graph and the following real house price graph based on Professor Robert Shiller's work (credits: the graph is from Barry Ritholtz's The Big Picture blog and is an update of a New York Times graphic with a possible projection by Steve Barry). Click on graph for larger image in new window. For the underlying data for the NY Times graphic, please see Professor Shiller's Irrational Exuberance website. This graph has suggested to many observers that house prices track inflation (i.e. that house price adjusted for inflation are stable - except for bubbles).
