Quality Adjusted Unit Value and Fisher Price IndicesReferencesIndex number theory informs us that if data on matched prices and quantities are available, a superlative index number formula is best to aggregate heterogeneous items, and a unit value index to aggregate homogeneous ones. The formulas can give very different results. Neglected is the practical case of broadly comparable items. This paper provides a formal analysis as to why such formulas differ and proposes a solution to this index number problem.IMF working paper ;WP/09/19.Index numbers (Economics)Economic indicatorsElectronic books.Index numbers (Economics)Economic indicators.Silver M.
