Four major home price indexes have been used in this study, and are based on different calculation methods and from different sources. The descriptive statistics indicate no meaningful differences among them. However, by analysing the orthogonalized impulse response and variance decomposition matrixes from the vector autoregressions, this study found some noticeable differences in the dynamic relationships between these indexes and three other housing factors – mortgage rates, existing home sales and new home sales – in addition to the inflation factor. The results may reflect the holding period effect in repeat sales house price indexes. Copyright © 2008 John Wiley & Sons, Ltd.
