This paper examines the inflation in housing prices between 1998 and 2005 and investigates whether this run-up in prices can be ‘‘explained’’ by increases in demand fundamentals such as population, income growth, and the decline in interest rates over this period. Time series models are estimated for 59 MSA markets and price changes from 1998 to 2005 are dynamically forecast using actual economic fundamentals to drive the models. In all 59 markets, the growth in fundamentals from 1998 to 2005 forecasts price growth that is far below that which actually occurred. An examination of the 2005 forecast errors reveals they are greater in larger MSAs, in MSAs where second home and speculative buying was prevalent, and in MSAs where indicators suggest the sub-prime mortgage market was most active. These latter factors are unique to the recent housing market and hence make it difficult to asses if and how far housing prices will ‘‘correct’’ after 2005.
