For Demark, the "price index for domestic supply" is used to analyze price trends related to the first commercial transaction of each commodity, i.e., producers' selling prices and importers' purchase prices exclusive of VAT and excise duties. This is not a Eurostat-standard PPI, which measures selling prices in the domestic and export markets. Monthly from 1981.
Statistics Denmark has calculated these monthly indices for various forms of this index since 1925 based on prices reported by selected producers and importers.
National accounts statistics use commodity price indices as the main source of calculations at constant prices, i.e. calculation of the actual economic development in Denmark. The business community often uses sub-indices for contract adjustment.
In the system for price indices on the producer- and import level the following prices are collected:
The calculation of the Price index for domestic supply is based on a and b to determine trends in prices relating to the first commercial transaction of a given commodity. Sub-indices are used to show distributions by use and origin (Danish commodities and imported commodities) as well as commodity groups.
The units used in the index are each individual companies, as determined by an outside legal entity. However, some of these companies may be combined into a single unit in certain situations, e.g. if they have centralized administration or are frachised.
The populations cover those commodities that are imported or Danish produced for the domestic market, with a few well-defined exemptions. Some commodities are not included because the turnover is too small or due to the nature of the commodities.
The exempted commodities can be found at http://www.dst.dk/en/Statistik/dokumentation/documentationofstatistics/price-index-for-domestic-supply/statistical-presentation
Commodity: The Customs Cooperation Council's 6-digit nomenclature Harmonized System (HS) from 1998. In some few cases where HS is not considered sufficiently detailed, subdivisions have been undertaken.
Nationality: A distinction is made between imported commodities and Danish commodities for the domestic market
Use: The breakdown of the Price index for domestic supply according to use is based on BEC (Broad Economic Categories prepared by the UN).
Elementary aggregate weights: Weights used for weighting the elementary aggregate indices, which are then used for compiling sub-indices and an aggregated Price index for domestic supply. The weights, which are based on the supply and use tables from national accounts for 2005, are equal to the sum of the import values and production values for the home market excluding VAT and excise duties.
Using a hierachical method, the different goods are first grouped into elementary aggregate indices, calculated based on a number of basic prices as geomentric indices, and are subsequently weighted as aggregate price indices. These are then calculated as Laspeyres indices for the final release.
Statistics Denmark revises published figures in accordance with the Revision Policy for Statistics Denmark. The common procedures and principles of the Revision Policy are in this case supplemented by a specific revision practice which states only final figures are published.
The index base year is advanced periodically.
At the same time, the sample is evaluated, and a disclosure analysis is performed. Detailed series that would violate confidentiality are suppressed.
