2.13.4 Should expenditure weights, and thus prices, be imputed in CPIs?
The standard definition of HFCE in the 1993 SNA includes many imputed expenditures for which prices are also imputed, principally goods and services that households produce for their own consumption, such as agricultural goods and household services (actual final consumption also includes social transfers in kind). Thus, a deflator for HFCE in the national accounts should cover the goods and services consumed by households, rather than those purchased by monetary transaction, and should therefore include imputed weights and prices for goods and services produced by households for their own consumption. However, deflation of the national accounts is rarely the principal role for a CPI. In his 1997 paper “Non-market Goods and Services in CPIs” 38 Peter Hill argues that the most objective measure of consumer inflation is provided by a price index based on goods and services purchased by households only in monetary transactions. Hill argues that imputed prices contribute no information about 38 Paper submitted by the ECE secretariat (prepared by Peter Hill) to the Joint ECE/ILO Meeting on CPIs, Geneva , November, 1997. 59 Price Indices © 2002 inflation and should thus be excluded from a CPI whether it is designed to measure inflation or the cost of living (a household does not need compensation for increases in its imputed expenditures). Thus, the index will not cover consumption of goods and services produced by households for their own use. It should, however, cover expenditure on the inputs to this production (but not expenditure on capital formation). The majority of members of a 1997 CPI advisory committee in New Zealand agreed that the credibility of a CPI is enhanced by its use of prices paid in market transactions, and reduced by the use of imputed prices and notional transactions. CPIs should, however, cover household expenditure on non-market goods and services sold by governments and non-profit institutions, despite the fact that the prices are reduced and may be independent of the general rate of inflation. These prices are an essential part of inflation experienced by households. There may be a need, however, to produce subsidiary indices excluding these prices for the purposes of analysing inflationary pressures. Download 465.51 Kb. Do'stlaringiz bilan baham: |
