The representative price observation covers nearly 1,300 economic units and more than 5,300 products monthly. The observed price, in the case of domestic sales, has been a basic price since 1994, excluding value added tax, and including price supplement and making part of sales revenue; in the case of external sales, it is a frontier price converted into forints at the rate of exchange valid on the day of fulfilment.
Producer price index: a weighted average of price indices of domestic sales and export sales.
Domestic sales price index: an index calculated from the net sales revenue of products and services sold inland, using base periods as weights.
Export sales price index: an index calculated from the sales revenue of products sold directly, through an agent or in a joint venture to external trade, using base periods as weights.
Calculation method: as a first step, the chain relative number for the respective month is calculated by representative item. Following this, the commodity-group indices are determined as arithmetic means of price ratios of the representative items, and then the price indices by class are calculated as weighted arithmetic means of the price indices of commodity groups.
Weights are revised annually, based on data from the ‘Annual statistical survey of industrial production’ (questionnaire No. 1039 in the National Statistical Data Collection Programme (OSAP in Hungarian)).
Weights are the values of annual sales of the products/services in a particular product group in the year two years prior to the reference year, in a particular sales direction.
As weights are changed annually, the change of the weight structure also has an effect on the base indices of aggregates.
Weights for particular years are shown in the attached table: weights.xlsx
Grouping by use: from 1998, covering NACE (3-digit) groups made according to the requirements of the European Union. From 2000, the EU modified the grouping of some divisions by use (MIG: Main Industrial Grouping). The most significant of these changes was that the collection, purification and distribution of water (division 41) was reclassified from the group of intermediate goods producer branches to the group of energy producer branches.
The Hungarian standard industrial classification of all economic activities’98 (TEÁOR’98) was introduced in the industrial producer price index computation in January 1999, which classification complies fully (at 4 digits, i.e. at class level) with the EU’s branch classification (NACE Rev.1). From January 2009, the branch classification is based on TEÁOR’08, which is consistent with NACE Rev.2.
Data suppliers: selected enterprises classified to sections mining (B), manufacturing (C), energy industry (D) and water and waste management (E).
