Constructing quality adjusted price indexes: a comparison of hedonic and discrete choice

ABSTRACT CONSTRUCTING QUALITY ADJUSTED PRICE INDEXES: a comparison,of hedonic and discrete choice models Nicole Jonker The Boskin report (1996) concluded that the US consumer,price index (CPI) overestimated the inflation by 1.1 percentage points. This was due to several measurement,errors in the CPI. One of them is called quality change bias. In this paper two methods,are compared,which can be used to eliminate quality change bias, namely the hedonic method and a method based on the use of discrete choice models. The underlying micro-economic fundations of the two methods,are compared,as well as their empirical implementation. Although the discrete choice model has not often been used in order to calculate quality adjusted price indexes it seems to be quite promising to do so. Keywords: logit models, cpi, consumenter behaviour, producer behaviour

A Reconsideration of Hedonic Price Indexes with an Application to PC's

SSRN Electronic Journal, 2003

This paper compares hedonic to matched model indexes. Matched model indexes are averages of the price changes of goods that remain on sampled stores' shelves. Since goods that disappear tend to have falling market values, matched model indexes select from the right tail of price changes. The BLS can construct hedonic indexes that correct for this selection and are justified

The Impact of the Price Index Formula on the Consumer Price Index Measurement

Statistika: Statistics and Economy Journal, 2019

The Consumer Price Index (CPI) is a common measure of inflation. Similarly to the Harmonised Index of Consumer Prices (HICP), it is determined using the Laspeyres index, thus data on the consumption of the basket of goods do not have to be current. The Laspeyres index, using weights only from the base period, may not reflect changes in consumer preferences that occurred in the studied year. In the ideal case, the CPI should be measured by one of the so called superlative price indices, such as the Fisher, Törnqvist or Walsh index formulas. The main problem with such indices is that they need expenditure data from the current period. The aim of the article is to assess the impact of the choice of the price index formula on the CPI measurement. We verify differences among known index formulas at the lowest and some higher data aggregation levels. We use known bilateral unweighted and weighted formulas together with their chained versions.
