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 Papers; Working Paper ;No. 2009/019Index numbers (Economics)Economic indicatorsMacroeconomicsimfIndex Numbers and Aggregationimfleading indicatorsimfMethodology for Collecting, Estimating, and Organizing Microeconomic DataimfPrice LevelimfInflationimfDeflationimfProduction, Pricing, and Market StructureimfSize Distribution of FirmsimfInformation and Product QualityimfStandardization and CompatibilityimfPrice indexesimfExport price indexesimfIndex numbers (Economics)Economic indicators.MacroeconomicsIndex Numbers and Aggregationleading indicatorsMethodology for Collecting, Estimating, and Organizing Microeconomic DataPrice LevelInflationDeflationProduction, Pricing, and Market StructureSize Distribution of FirmsInformation and Product QualityStandardization and CompatibilityPrice indexesExport price indexesSilver Mick1449453DcWaIMFBOOK9910788349703321An Index Number Formula Problem3712976UNINA
