This article examines the relation between systematic price changes and the
heterogeneity of investors' information sets in real estate asset markets.
The empirical implications rely on a theoretical economy in which informat
ion asymmetry alters the dynamic relation between returns and trading volum
e. We employ a filter-rule methodology to determine predictability in retur
ns and augment the return-based conditioning set with trading volume. The a
dditional conditioning information is necessary since the model is underspe
cified when predictability is based on returns alone. Our results provide n
ew insight into the coexistence of informational and noninformational excha
nge in the speculative markets for real estate assets. Specifically, we fin
d that the predictability of real estate returns is generally more indicati
ve of portfolio rebalancing effects than an adverse-selection problem. Thes
e results are unique in addressing the time-variation in information asymme
try.
