The empirical literature on price indices consistently finds that aggregation methods have a considerable impact … the appropriateness of aggregation. A hedonic regression framework is used to test for item homogeneity across four … supermarket chains and across stores within each of these supermarket chains. We find empirical support for the aggregation of …

The impact of weekly, monthly and quarterly time aggregation on estimates of price change is examined for nineteen … different supermarket item categories over a fifteen month period using scanner data. We find that time aggregation choices (the … superlative indexes. Monthly and (in some cases even) quarterly time aggregation were found to be insufficient to eliminate …
