Category: Purchasing power parities

The preparatory survey carried out by participating countries prior to a price survey. The objective is for each country to investigate its national market to ascertain the availability, comparability and representativity of the products specified in a pre-survey questionnaire. It involves visiting outlets, including those that will be visited during the actual price collection, to obtain information on the products specified, on their replacements and on possible alternatives from sales personnel and through observation. It also involves consulting the internet, trade and consumer magazines, catalogues and brochures, importers and experts. Country responses to the pre-survey questionnaire are used to draw up the product list for the price survey (2012 Methodological manual on purchasing power parities).
