Abstract:
In hedonic housing price
modeling, real estate researchers and practitioners are often not
completely ignorant about the parameters to be estimated. Experience and
expertise usually
provide them with tacit understanding of the likely values of the true
parameters. Under this scenario, the subjective knowledge about the
parameter value can be incorporated as non-sample
information in the hedonic price model. This paper considers a class of
Generalized Stein Variance Double k-class (GSVKK) estimators, which
allows real estate practitioners to introduce potentially useful
information about the parameter values into the estimation of hedonic
pricing models. Data from the Hong Kong real estate market are used to
investigate the estimators’ performance empirically. Compared with the
traditional Ordinary Lease Squares approach, the GSVKK estimators have
smaller predictive mean squared errors and lead to more precise
parameter estimates. Some results on the theoretical properties of the
GSVKK estimators are also presented.
