3.1. Data description | |||
The purpose of producer price index survey is to collect the data on monthly price changes of industrial products produced and sold by enterprises on the domestic market. Producer price index of industrial products represent important economic indicator which can be used as an inflation measure; as time series deflator, especially for needs of National Accounts and industry, and as a tool for harmonising prices when concluding various sales contracts. |
|||
3.2. Classification system | |||
NACE Rev. 2, CPA Version 2008 |
|||
3.3. Coverage - sector | |||
Indices are calculated for the following sections of industrial activity: B (Mining and quarrying), C (Manufacturing), and D (Electricity, gas, steam and air conditioning supply) of NACE Rev. 2 classification. |
|||
3.4. Statistical concepts and definitions | |||
Producer prices of manufactured products are the prices that industrial manufacturers apply in selling the products of their own production range to commercial and other enterprises in the domestic market. The selling price is increased for the amount of the compensation obtained by the seller and deducted for the amount of the discount and rebate as well as the value added tax and excises. Producer price indices are relative numbers that show changes in producer prices from period to period. Price indices are calculated for certain products (individual indices), for groups of products and for all products included in the list (total index). The monthly index shows by how much on average prices in the current month changed in comparison with the previous month. The quarterly index shows by how much on average prices in the current quarter changed in comparison with the previous quarter. The annual index shows by how much on average prices changed in the last 12 months. The average annual index shows by how much on average prices changed in the last n months of the current year compared to the same period of the previous year. |

|||
12.3. Completeness | |||
All national requirements are fulfilled. |
|
|||
13.1. Accuracy - overall | |||
The accuracy of Producer price index survey is generally considered to be high. The accuracy of source data is monitored by assessing the methodological soundness of price and weight sources and the adherence to the methodological recommendations. Appropriate actions are taken to identify and eliminate potential sources of errors. |
|||
13.2. Sampling error | |||
Sampling error cannot be calculated because the survey was not conducted on the basis of a random sample. |
|||
13.3. Non-sampling error | |||
The response rate is about 70%. Depending on size or representativeness, companies are contacted by phone in order to provide data on time. The price of the temporarily unavailable product is determined by contacting the company from which it is required to estimate/assess the missing price or to repeat the last declared price. In cases where an industrial enterprise ceases to produce a product of a certain quality for which prices are collected, or if the product of that quality is 'non-marketable goods' then a new product of a certain quality that is best sold is defined, and it is expected to be sold in a longer period of time and in large quantities. Prices for the new selected quality product are given simultaneously for the current and previous month. Companies are obliged to explain any change in quality. |

|||
18.1. Source data | |||
The main source of data for the calculation of the Producer price index of industrial products is the monthly survey on producer prices of industrial products. This survey includes companies classified in the sections of mining and quarrying, manufacturing and supply of electricity, gas, steam and air of the NACE Rev. 2 classification, with more than five employees that meet the unit of measurement prescribed by the Nomenclature of industrial products per unit of product. It also includes companies classified in other sections of the NACE Rev. 2 classification, which are composed of industrial drives or other organizational forms that are engaged in industrial production. Sample and weights are based on annual industrial survey. The most important products in each division have been selected for price changes monitoring, i.e. products with the highest sale on the domestic market. Producers are selected according to their participation in the production of certain products. |
|||
18.2. Frequency of data collection | |||
Monthly. |
|||
18.3. Data collection | |||
Reporting method is used for data collection. Questionnaires are filled by reporting units between the 14th and 16th of each month for the current month. The selling prices of manufactured products are the prices at which the producers sell their products to regular customers on the domestic market in the largest quantities. Reporting unites provide prices for the current and previous month. If there were no sales in the reporting month, the reporting unit should enter the price at which sales would be carried out if the customer appeared. |
|||
18.4. Data validation | |||
Data validation is performed in accordance with defined criteria of control. The validation is performed before and after the data are entered. Reporting units confirm the price of products by entering the prices for the current and previous month and, if any changes occur, they need to be explained in the questionnaire. In case of major deviations, reporting units are contacted. Calculated indices are also checked before publishing. |
|||
18.5. Data compilation | |||
Producer price indices are relative numbers that show changes in producer prices from period to period. Price indices are calculated for certain products (individual indices), for groups of products and for all products included in the index list (total index). Prices of products are used for calculation of elementary indices, and calculation of aggregate indices is carried out by weighting individual indices according to the Laspeyeres formula. For the purposes of this survey, December of the previous year is used as a price reference period. Weights are based on annual industrial survey. |
