Changing product quality poses a challenge for the computation of price indexes, in particular in technologically advanced industries. We assess the differences between traditional and quality-corrected indexes by computing hedonic and matched-model price indexes for personal computer database...

Changing product quality, rapid technological progress, and short product life cycles make it difficult to compute indices that correctly reflect the true price movements of IT products. This paper assesses the differences between traditional and quality adjusted indices by providing results for...
