Thus several countries include a purely notional cost of depreciation as an additional index component, applying an arbitrarily estimated, or rather guessed, depreciation rate to the value of the stock of owner-occupied dwellings.
If one or other of these measures of the consumption of the services of owner-occupied dwellings is included in consumption, then it must be included in income too, for income equals consumption plus saving. This turns out to be quite complicated, conceptually as well as in practice.
A consumer price index compares how much it would cost now to do exactly what consumers did in the reference-period with what it cost then. The different indices differ only in the weights applied to the different 8, item—area indices.
It is said that this is more than just a matter of terminological uniformity.
Variants of the debt profile method are employed or have been proposed. The application of this principle in the owner-occupied dwellings component of a consumer price index is known as the "debt profile" method. The point is to make the best use of whatever data are available.
The other, the "rental equivalent" approach, is to let it to someone else for the year, in which case the cost is the rent that could be obtained for it. Although the argument has been expressed in connection with owner-occupied dwellings, the logic applies equally to all durable consumer goods and services.
It does not require an estimate of how much that identical person is paying now on the actual house she bought ineven though that is what personally concerns her now. On the other hand, with the rental equivalent approach, there may be difficulty in estimating the movement of rental values Consumer price index research papers types of property which are not actually rented.
There are only two general principles for the estimation of weights: Since these accounts include the equivalent rental value of owner-occupied dwellings, the Consumer price index research papers rental approach would have to be applied in the consumer price index too. Only a large-sample Household Expenditure survey can provide a regional breakdown.
Thus, with the alternative cost approach, if house prices are rising fast the cost can be negative and then become sharply positive once house prices start to fall, so such an index would be very volatile. Owner-occupiers and the price index[ edit ] The way in which owner-occupied dwellings should be dealt with in a consumer price index has been, and remains, a subject of heated controversy in many countries.
Products bought on credit would then be treated in the same way as owner-occupied dwellings. An example might be an elementary aggregate for sliced bread sold in supermarkets in the Northern region.
Even obtaining mortgage interest rate data can be a major task in a country with a multitude of mortgage lenders and many types of mortgage. This development makes possible improved Household Expenditure surveys, as Statistics Iceland has demonstrated.
The other argument is that the prices of new dwellings should exclude that part reflecting the value of the land, since this is an irreproducible and permanent asset that cannot be said to be consumed.
Consumer price indices in the United States[ edit ] Main article: In the second stage, weighted averages are computed of these 8, item—area indices. Some countries have used a three-year average in recognition of the fact that household survey estimates are of poor quality.
Estimating weights[ edit ] The outlet and regional dimensions noted above mean that the estimation of weights involves a lot more than just the breakdown of expenditure by types of goods and services, and the number of separately weighted indices composing the overall index depends upon two factors: Some people regard this as odd.
The statistical sources required for regional and outlet-type breakdowns are usually weak. This is not necessarily the kind of classification that is most appropriate for a consumer price index. One example is to include down payments as well as interest.
It accounts for 88 percent of the U. Furthermore, the weight for owner-occupied dwellings could be altered considerably when reweighting was undertaken.
Similarly, if the market shares of the different types of product represented by product types are known, even only approximately, the number of observed products to be priced for each of them can be made proportional to those shares.
The nature of the data used for weighing[ edit ] No firm rules can be suggested on this issue for the simple reason that the available statistical sources differ between countries. Weight averages of these in turn provide sub-indices at a higher, more aggregated level, e.
In the UK the retail price index RPI does not relate to the whole of consumption, for the reference population is all private households with the exception of a pensioner households that derive at least three-quarters of their total income from state pensions and benefits and b "high income households" whose total household income lies within the top four per cent of all households.
Application of the principle thus requires that the index for our one house owner should reflect the movement of the prices of houses like hers from to and the change in interest rates.
These reports cover areas with large populations and represent a particular region subset. Then, there is the point that a rise in interest rates designed to halt inflation could paradoxically make inflation appear higher if current interest rates showed up in the index.
Two arguments of an almost theological character are advanced in connection with this transactions approach. Furthermore, since strict logic is to be adhered to, there are durable services as well that ought to be treated in the same way; the service consumers derive from appendectomies or crowned teeth continue for a long time.
Thus response burden is markedly reduced, accuracy is increased, product description is more specific and point of purchase data are obtained, facilitating the estimation of outlet-type weights. Thus only new dwellings would be included.The Consumer Price Index is a measure of the prices of a fixed market basket of some consumer goods and services purchased by a "typical" urban consumer 2 / Rural Marketing In India.
The Consumer Price Index (CPI) is a measure of the average change over time in the prices paid by urban consumers for a market basket of consumer goods and services. Indexes are available for the U.S. and various geographic areas. As inflation approaches zero, it becomes increasingly important to examine the price indices on which monetary policy is based.
The most popularly used aggregate price statistic in the U.S. is the Consumer Price Index (CPI), a statistic that appears to be a focal point in monetary policy deliberations.
Since the publication of the Consumer Price Index (CPI) Manual, methods and best practices have continued to evolve. Any relevant technical material and research papers can also be forwarded to this mail box. Draft Chapters for Comments.
