What does the survey comprise?
The survey provides monthly data on terms of trade in goods.
The survey covers total imports and exports of goods.
Year survey started
The series based on 2010=100 started in January 1990 and was first published on 28 June 2013.
The figures are published about six or seven weeks after the end of the month under review.
The figures are consistent with data on import and export prices in the quarterly and annual National Accounts. As a result, figures remain “provisional” for a relatively long period of time. The figures are adjusted to the provisional, revised provisional and definite estimates (and subsequent revisions) of the National Accounts.
How is the survey conducted?
Calculations are based on value figures in euros as measured by Statistics Netherlands in its monthly statistics on international trade in goods. First, value changes are calculated, which are subsequently adjusted for price changes at a detailed level of the goods classification used for National Accounts purposes. This results in figures on the volume changes of imports and exports. Changes in export/import prices are calculated by dividing the total value of exports/ imports of goods by the volume of exports/imports of goods. The change in the terms of trade results from dividing prices of exports by prices of imports.
Quality of the results
The figures are comparable over time.
Terms of trade figures, import prices and export prices may be adjusted once new or updated source information becomes available in the monthly international trade statistics or producer prices. In addition, monthly price changes are adjusted retrospectively to fit those of imports and exports of goods in the quarterly National Accounts and the annual National Accounts. A complete revision of the National Accounts is done once every five or ten years.
