Who is responsible for the quality and the accuracy of the PPP results?
The accuracy of the PPP results depends both on the extent to which the OECD and Eurostat have used correct procedures for editing the data supplied by countries and for combining them to calculate parities at the different levels of aggregation and on the extent to which Member countries have supplied representative price data and accurate expenditure data. It is a shared responsibility and the shared nature of the Programme has been emphasised by the extensive consultations that take place at all stages of the work from the initial definitions of the goods and services to be priced up to the final review of each country’s PPP results for basic headings. Experts from participating countries have also played a major role in the periodic reviews of technical issues that have been held in the past.
