Depending on the method used to produce export price indices, however, the latter may not be available at a detailed industry level. This is particularly the case if indices are derived from trade data using a unit value approach. Table 17 shows information regarding OECD countries that publish output series including or excluding exports, and separate series for the domestic and export markets. Though incomplete, it can be seen that in at least eight OECD Member countries, PPIs cover prices that are charged in domestic markets only, i.e. export prices are not included.

Their use gives a measure of price change of all transactions for those products (i.e., inter- plus intra-industry sales). Net sector weights are based on the value of sales to establishments outside the industry or group of industries in question (inter-industry sales only). The differences between gross and net weights depends on the level of aggregation being considered in the industrial classification and on the extent of intra-industry transactions. Obviously gross weights will always be larger for a particular industry heading but to a varying degree across industries depending on the number of establishments, complexity of the activity, degree of horizontal or vertical integration, etc. within each industry heading. Industries where horizontal or vertical integration is increasing within the industry heading will show declining gross weights but constant net weights. Net weights will also decline where the integration results in reclassification of units to other industry headings, but the size of this effect will obviously depend on the levels of aggregation. The differences between gross and net weights will become larger at successively higher levels of aggregation. MEI Methodological Analysis - Supplement 2 © 2002 76 Gross output indices are needed for deflation of industry output in the national accounts, where indices are used at a disaggregated (4-digit ISIC) level. However, aggregation of industry or group indices using gross weights will result in some degree of double-counting of the price changes of raw materials, i.e., the higher the number of transactions involved in the production of a finished good, the higher the effective weight of the raw materials of that good in any aggregate indices across stages of production. The double-counting will be greater in industries with high raw material costs (high input-output ratios). To avoid the double-counting problem, net sector weights should be used in the compilation of higher level aggregates and for indices used to analyse how inflationary pressures are transmitted from one sector to another. Ideally, stage of processing indices should also be compiled using net sector weights. Increasingly, countries are moving towards the use of net weights for compiling aggregate indices for inflation monitoring but since detailed input-output tables are needed to derive net weights, not all countries are in a position to do this. The stage of processing concept categorises flows of goods and services according to their economic destination in a sequential basis along the production chain. Input-output tables form the basis for the categorisation. The most common categorisation is: • raw materials, where it may be useful to compile separate indices for domestic production and imports; • intermediate goods, where again, it may be useful to compile separate indices for domestic production and imports; • finished goods, often split into consumer and investment goods, for which separate indices for exports may be useful. This range of indices is compiled for specific industries where possible, otherwise for the whole economy. Download 465.51 Kb. Do'stlaringiz bilan baham: |
