Many researchers working with analyses and predictions of the prices o
f owner occupied houses have found that econometric models based on 'e
conomic fundamentals' fail to explain more than a fraction of the move
ments of the prices. This is especially the case in periods of rapid c
hange. Often, this failure is attributed to psychological factors such
as price expectations among the market participants. This paper compa
res observed market prices and equilibrium prices under three differen
t hypotheses of the formation of price expectations. The results from
the investigations indicate that price expectations are formed through
an extrapolation of the trend in house prices rather than through a p
rocess based on knowledge of the structure of the housing market, econ
omic fundamentals and demographic trends.
