Definition: Comparison resistant

Category: Purchasing power parities

A term first used to describe non-market services which are difficult to compare across countries because: they have no economically- significant prices with which to value outputs, their units of output cannot be otherwise defined and measured, the institutional arrangements for their provision and the conditions of payment differ from country to country, and their quality varies between countries but the differences cannot be identified and quantified. Increasingly, the term is being used to	describe construction and market services such as telecommunications whose complexity, variation and country specificity make it difficult for them to be price comparably across countries (2012 Methodological manual on purchasing power parities).

Increasingly, the term is being used to describe capital goods and many market services whose complexity, variation and country specificity make it difficult for them to be price comparably across countries (2005 Methodological manual on purchasing power parities). http://ec.europa.eu/eurostat/product?code=KS-RA-12-023&mode=view Eurostat and Organization for Economic Cooperation and Development (OECD), "Eurostat - OECD Methodological manual on purchasing power parities (2005 Edition)", Methods and Nomenclatures, Office for Official Publications of the European Communities, Luxembourg, 2006European Union, Regulation (EC) No 1445/2007 establishing rules for the provision of basic information on PPPs, Official Journal of the European Union No L 336, 20.12.2007, p. 1 - 24
