The data are developed in compliance with the general requirements of Handbook of EU Agricultural Price Statistics, Version 2.0 March 2008.
Thus achieving harmonization in the field of price statistics and indices in agriculture with the EU practice regarding the definitions, techniques of price registration, type of calculated indices, survey periodicity and classifications used.
Data sets of quarterly and annual Producer Price Indices in Agriculture are calculated.
The main purpose of the Producer Price Indices in Agriculture is for:
· information about the change in trend in producer prices in agriculture;
· comparisons of price changes of different products within a country or between member states of the European Union;
· comparisons of the change in trends in producer prices and in the prices of goods and services currently consumed in agriculture;
· deflation of the agricultural output.
· Classification of Economic Activities - 2008 (CEA-2008, for international use NACE.BG-2008);
· Nomenclature of production in agriculture, forestry and fisheries (Prodagro);
· Annex 1 of the Handbook for EU agricultural prices, version 2.0, March 2008.
According to the Handbook for EU agricultural prices, version 2.0, March 2008 the scope of the Producer Price Indices in agriculture should:
- include the value of production sold to dealers;
- include the value of direct sales by farmers of crop products made to other agricultural units;
- include the value of direct sales by farmers on the domestic market;
- include the value of direct sales by farmers abroad (direct exports);
- include the value of products processed on the farm, which, except in the case of olive oil and grape must or wine, must be calculated on the basis of the quantities and prices of the raw materials from which they are made;
- include the value of product related levies/taxes (other than deductible VAT);
- exclude the value of any monetary compensation received by farmers in respect of the destruction of given quantities of products;
- exclude the value of subsidies on products which farmers might have received;
- exclude the value of consumption of own produce on agricultural holdings;
- exclude the value of products sold from private, non-agricultural gardens;
- exclude the value of changes in stock.
|Statistical concepts and definitions|
· Producer Price Indices in Agriculture
The indices are calculated by the Laspeyre?s formula. It can be calculated for a period of several years without being necessary to alter the basket of representative products or the weights. Furthermore the parameters used for the calculation of the indices are well known at the time the base is established. Changes only need to be made when the evolution of the products used and of their relative importance have made the basic structure inappropriate.
· A weighting scheme for calculating the Producer Price Indices in Agriculture.
For the calculation of Producer Price Indices in Agriculture (Annex 2 of the Handbook) a weighting scheme should be available. Weights are calculated within the frame of the economic accounts for agriculture and they reflect the value of sales of agricultural products during the period (base) - quarter or year.
· Agricultural holdings ? juridical and physical persons;
· Processing Industries;
· Wholesalers of agricultural products.
Framework of the study is:
· Annual Report of agricultural enterprises;
· Annual Report of non-financial enterprises.
Units for observation are selected through defining threshold in terms of value and with requirement to cover 75% of the channel realization.
For all territory of the country (NUTS0).
From 2005 onwards.
· 2005 = 100; 2010=100 (base of Eurostat)
· corresponding quarter of the previous year = 100
· previous year = 100
