The methodological explanation
Consumer's prices index (CPI) - is concerning exponent that measures general modification cost of the fix admission goods and services, are being bought by an average consumer, that is it characterizes modification of total sum consumer's expenses of population at a certain time under invariable number of consumption goods and services. It characterizes modification at time of total level prices for goods and services are being acquired by population for unproductive consumption. The main prescription CPI is the appreciation of the dynamics of prices for consumer goods and services. It is calculated on Laspayres's formula. 569 representative groups of goods and services are used in calculation CPI.
CPI is one of the most important exponent characterized the level of inflation and it is used for the purposes of the state policy, analysis and prognosis prices processes in economy, revision of minimum social guarantees, decision juridical controversial questions.
CPI is used as well on calculation of exponents system of national calculations for appraisal of expenditures in constant prices for final consumption of housekeeping that is that is one of the most important components of final using of gross output and for indication of the population income.
The point of information for the calculation CPI is statistics of registration prices for concrete goods and services. In virtue of these data we define average compare prices for concrete goods and services of the current and previous period. The compare price is that being registrated at one and the same enter price of trade for one and the same or analogous goods in quality. For the purpose of getting objective information about standard of prices and their dynamics, selection of trade enter prices for registration prices is made thus the results of this selection would reflect more exactly as possible local specific of trade and service.
It is necessary trade units are being present that are situated in different regions of the city, different in the size (large, middle and small) and of different forms property and types (state, cooperative, commercial and private commission property; town and unformal markets).
For each goods (service) 2-3 prices are being registered in deferent trade units in the centre of the town and 3-4 prices in the outskirts. It is necessary with this that only one registration about each goods, in one trade unit to be made.
While to select base enter prices of service it is necessary to take one's bearing (for example Everyday Service Centre, Personal Service Shop) those are being the most visiting enter prices or of all the year round function. Taking into consideration that lately unformal market (or street trade has widely spread, it is necessary to registrate prices of goods there too.
For definition of the structure consumer outlay and calculation indexes of consumer prices data of statistics budgets about money outlay of the population having been used for buying goods and payment made services are used. Registration of prices and tariffs for consumer goods and pain services to population and calculation of average prices as well as the index of prices depending on goods and services are made weekly and monthly on special forms of registation of consumer prices.
Produce price indices (PPI) - is counted on the base of industrial institutes and price registration of presented products. In registration it is taken the real prices of produced in current month products.
Produce price indexes was worked out on both products and types of economical activity affording opportunity for accounting to international methodology. Goods selected for price collection was koded 10 number industry products, and the institutes on the base of widen and classificatory system of 5 number industry for economical activity.
For global pricing based on industrial activity of price changes of PPI producers is considered the main and the term indexes, concrete goods or the it is used as indicators of price changes of goods' groups. Every month, secsions of types economical activity classification C, D, E (extract, manyfacture, power engineering) and down secsions it is counted 17 indexes and its dynamic terms, and month the produced average weight computer production from the side of republic industry institutions forms base information the PPI account on the field of methodology, and also in the system of codification of primary informations the using of international standarts gave a possibility to State Statistic Committee to take indicators wich would be compared in the international level.
Producer prices indices of agricultural products (APPI) - characterize level and dynamics of prices of agricultural products realized by different ways by agriculture enterprices, farmers' economy and households. Observation of the prices of agricultural products in conducted on the base of sample of agriculture enterprices, peasant (farmer) farms and households.
The obtained information is used on analysis of changes in realization of agricultural products as well as definition of role of price in changes of incomes of producers' of agricultural products.
Indices of tariffs for cargo transportation is considered for estimation of the change rate of transportation tariff of different type of transport as well as calculation of growth (decrease) rate of GDP and definition of the deflationary indicators and other macroeconomic indicators. These indices are used for describing of basic prices of transportation by different transport types of transport enterprises. Indices of transportation tariff are applied on forecast at macro level and implementation of different economic calculations. Indices of transportation tariff give possibility to determine its change during the report period without consideration of change in structure of transported freight by type of freight, size package, delivery date, distance of transportation, transportation territory, movement, level of load lifting and etc.
Total index of transportation tariff of all transport types is defined based on indices of transportation tariff of railway, pipeline, sea, motorway, and airway.
Registration of transportation tariff of each transport type is conducted according to representative services.
Representative services means transportation of freights more than one tone by concrete transport. Representative service by motor transport means transportation of freight of one tone by defined distance or operation during one hour depends its payment. By foreign sea transport it is observed average monthly income by transportation of one tone cargo.
