CONCLUSIONS""; ""References""Statistical offices try to match item models when measuring inflation between two periods. For product areas with a high turnover of differentiated models, however, the use of hedonic indexes is more appropriate since they include the prices and quantities of unmatched new and old models. The two main approaches to hedonic indexes are hedonic imputation (HI) indexes and dummy time hedonic (DTH) indexes. This study provides a formal analysis of the difference between the two approaches for alternative implementations of the Törnqvist "superlative" index. It shows why the results may differ and discusses the issue of choice between these approaches.IMF Working Papers; Working Paper ;No. 2006/181Inflation (Finance)Price indexesCementimfCeramicsimfCommodity exchangesimfCommodity marketsimfConsumer price indexesimfDeflationimfFinanceimfFinance: GeneralimfGeneral Financial Markets: General (includes Measurement and Data)imfGlassimfInflationimfInvestment & securitiesimfInvestments: MetalsimfMacroeconomicsimfMetals and Metal ProductsimfPrice indexesimfPrice LevelimfSilverimfUnited StatesimfInflation (Finance)Price indexes.CementCeramicsCommodity exchangesCommodity marketsConsumer price indexesDeflationFinanceFinance: GeneralGeneral Financial Markets: General (includes Measurement and Data)GlassInflationInvestment & securitiesInvestments: MetalsMacroeconomicsMetals and Metal ProductsPrice indexesPrice LevelSilverHeravi Saeed1674631Silver Mick1449453International Monetary Fund.Statistics Dept.DcWaIMFBOOK9910821246803321The Difference Between Hedonic Imputation Indexes and Time Dummy Hedonic Indexes4238549UNINA
