PPPBasedEconomicValuation
PPPBasedEconomicValuation
is a class of relations used to state international economic information in U.S. dollar amounts. The U.S. dollar amounts are derived from Purchasing Power Parity conversions of economic totals (e.g., GDP) given in local currency. This contrasts with a method of conversion based on currency exchange rates. The PPP method is used by the CIA World Fact Book for the purpose of presenting economic data for all countries covered. Their basis for PPP dollar price weights is the UN International Comparison Program (UNICP) and the work of Professors Robert Summers and Alan Heston of the University of Pennsylvania.
