prices for individual items are collected every month to support production of the index. Items are selected on the basis of local purchasing patterns, which means that different products and services may be priced in different areas. With some effort, these data could be used to compute average prices for selected specific services that are priced in multiple areas.
Clearly, there are data problems with both input- and output-based approaches to the construction of a satellite account that reflects household production. Again, however, we believe these are no more difficult to surmount than were the problems that faced those who constructed the initial versions of the NIPAs. Moreover, undertaking both would provide an illuminating check on the accuracy of the household production satellite account.
