Backcasting upward bias in price index over long periods of time yields levels of real consumption two or four centuries ago that are implausibly low, raising the possibility that price index bias for important products may have been zero or even negative at some point in the past. This paper...

Results of hedonic price regressions for personal computer operating systems and productivity suites advertised in PC World magazine by retail vendors during the time period 1984 to 2000 are reported. Among the quality attribute variables we use are new measures capturing the presence of network...

Article Classification: Research Paper (Construction or testing of a model or framework).Purpose: The repeat sales house price index has been widely used to measure house price movements on the assumption that the quality of properties does not change over time. This study aims to develop a...

We show that hedonic price indexes may be biased when not all product characteristics are observed. We derive two primary sources of bias. The first is a classical selection problem that arises due to changes over time in the values of unobserved characteristics. The second comes from changes in...

The price index for dwelling rents in Finland have been measured from data that is collected in connection with the Labour Force Survey (LFS). The construction of index series is based on the base strategy with log-Laspeyres as the index number formula. Some problems have emerged: First, the...

Measurement of price change is based on averages - also, hedonic price index numbers. As NSIs obtain scannerdata having varying content, question arise: what is correct average to use? We compare in this paper price change estimates based on most known averages and index numbers including...

Statistics Finland has a relatively long experience in constructing indices of prices of old dwellings and old one-family detached houses using the hedonic approach where regression analysis and classification of flats are combined. Also, for new one-family detached houses a bilateral...

Statistics Finland has relatively long experience in constructing indices of prices of old flats using the hedonic approach where regression analysis and classification of flats (i.e. stratification) are combined. Practically this means: First the price model is based on the fixed effect model...
