IMPLICATIONS FOR CPI COMPILATION""; ""VI. SUMMARY""; ""Data Annex""The Consumer Price Index Manual (2004) provides guidelines for aggregation formulas that are promulgated at IMF training courses and technical assistance missions. This paper develops elementary level aggregation theory to better inform users and compilers. Most countries use either the Dutot or Jevons index formula. These formulas generally give different results; advice on choice of formula matters. Using an approach based on sample estimators, and an illustration based on scanner data, the paper shows how differences in these formulas can be explained by changes in price dispersion and, in turn, by product heterogeneity. Implications for choice of formula are considered.IMF Working Papers; Working Paper ;No. 2006/174Consumer price indexesPrice indexesConsumer price indexesimfDeflationimfDemographic Economics: GeneralimfDemographyimfExpenditureimfExpenditures, PublicimfIncome economicsimfInflationimfLabor economicsimfLabor Economics: GeneralimfLaborimfLabourimfMacroeconomicsimfNational Government Expenditures and Related Policies: GeneralimfPopulation & demographyimfPopulation and demographicsimfPopulationimfPrice indexesimfPrice LevelimfPublic finance & taxationimfPublic FinanceimfUnited KingdomimfConsumer price indexes.Price indexes.Consumer price indexesDeflationDemographic Economics: GeneralDemographyExpenditureExpenditures, PublicIncome economicsInflationLabor economicsLabor Economics: GeneralLaborLabourMacroeconomicsNational Government Expenditures and Related Policies: GeneralPopulation & demographyPopulation and demographicsPopulationPrice indexesPrice LevelPublic finance & taxationPublic FinanceSilver Mick1449453Heravi Saeed1816317DcWaIMFBOOK9910968073303321Why Elementary Price Index Number Formulas Differ4372361UNINA
