Exchange rates, purchasing power parities (PPPs) for GDP, for private consumption and for actual individual consumption.  Exchanges rates are collected from the IMF publication “International Financial Statistics” and refer to IMF series “rf”: year average national currency per U.S. dollars. PPPs are the rates of currency conversion that equalise the purchasing power of different countries by eliminating differences in price levels between countries. When converted by means of PPPs, the expenditures on GDP for different countries are in effect expressed at the same set of prices so that comparisons between countries reflect only differences in the volume of goods and services purchased.
