We shed light on housing price inertia by investigating how the home-sale mechanism affects housing price dynamics. Using Australian data, we find that auction prices forecast better and display less momentum than negotiated prices. These findings are robust to alternative price measurements and different sample selection corrections. Motivated by micro-theory that predicts different weights for buyer and seller values in auction and negotiated prices, we decompose housing prices into two diffusion processes and interpret them as buyer value and seller value, respectively. The seller value updates much more slowly, which could be an important driver of housing price inertia.

This paper contributes to the empirical literature on price stickiness by documenting a high rate of nominal rigidity among housing rents in the United States between 1974 and 1981. Of the units studied, 29% had no change in nominal rents from year to year. The incidence was much higher (a) in years and cities with a low median nominal rent growth rate, and among (b) units whose tenants continued from the previous year and (c) units in small buildings. A little less than half of the nominal rigidity can be ascribed to grid pricing. Possible explanations, as well as the likely distributive and allocative implications, are discussed.
