<P>此贴单列的原因：</P>
<P>特征价格是微观经济学价格理论在异质化产品分析中应用的一个重要领域。该领域不同于一般的微观分析。在国外基于hedonic price 的分析也没有被并入微观经济学的主流。如果版主没有意见，我下面将陆续发一些这方面的专题。所以才单列的。不知道这样合适否？如果不合适，我只好认罚了。</P>
<P>Hedonic Price Index and The Matched Models Approach</P>
<P>We consider three approaches to estimating quality-adjusted price changes:
(i) the dummy variable approach from a hedonic regression, (ii) a superlative
or exact hedonic index and (iii) a matching technique—a technique akin to
that used by statistical offices. The dummy variable approach is prevalent in
the literature and has been used for independent estimates of quality changes
when commenting on sources of error in consumer price indexes. However,
the availability of scanner data provides an opportunity to utilize data on the
prices (unit values), volumes and quality characteristics of a much wider
range of transactions and to consider methods less restrictive than the
dummy variable approach. The practical use of superlative or exact hedonic
index and matching techniques using scanner data is explored, and the results
from all three methods are compared. A feature of the paper is the breadth
of the empirical work. It not only encompasses three different approaches,
but extends across four different types of consumer durables. The manner in
which the three approaches relate to each other is explored and the implications
for quality-adjusted price changes is discussed.</P>
