The OECD, Eurostat, and 47 participating countries work together in establishing purchasing power parities, or PPPs, in order to compare the price and volume levels of the GDPs. This programme is called the Eurostat-OECD PPP Programme. The manual gives a complete, detailed and up-to-date description of the functioning of the programme. This includes its organisation, the various surveys carried out by participating countries and the ways PPPs are calculated and disseminated. It also provides guidance on the use of PPPs.




Health expenditure accounts for a large share of GDP in EU Member States and OECD Member Countries. Both governments, as providers of health services, and households, as recipients of the services, are interested in knowing whether the differences in expenditure across countries reflect different amounts of health services being consumed or health services having different price levels. International price and volume comparisons of health expenditures provide countries with a means to assess their national health systems – at least in principle. In practice, inter-country comparisons of health expenditures are difficult to carry out because health services are comparison resistant with the institutional arrangements for their provision and payment varying from country to country.
