This chapter compares the existing treatment for quality adjustment and sample maintenance for televisions in the Canadian Consumer Price Index (CPI) with what might be feasible using scanner data. Televisions exhibit relatively uncommon price behavior. If prices generally are rising, the stretch-link method will tend to keep the index down, and if they are falling it will tend to keep it up. Prices for 20-inch TVs have fallen substantially less than prices for 27-inch TVs. The cost savings in using scanner data are the field expenses currently incurred in collecting data and the processing and editing costs. Any method that depends on using all scanner data requires an increase in resources or a simpler approach. Yet, there are challenging questions to answer referring to the choice of data to be included in the calculations, how to group together different products, and how to describe them.
