Purchasing Power of Currency
The "real exchange rate" (RER) is the purchasing power of a currency relative to another. It is based on the GDP deflator measurement of the price level in the domestic and foreign countries, which is arbitrarily set equal to 1 in a given base year. Therefore, the level of the RER is arbitrarily set depending on which year is chosen as the base year for the GDP deflator of two countries. The changes of the RER are instead informative on the evolution over time of the relative price of a unit of GDP in the foreign country in terms of GDP units of the domestic country. If all goods were freely tradable, and foreign and domestic residents purchased identical baskets of goods, purchasing power parity (PPP) would hold for the GDP deflators of the two countries, and the RER would be constant and equal to one.

Famous quotes containing the words purchasing power, purchasing, power and/or currency:
“At present cats have more purchasing power and influence than the poor of this planet. Accidents of geography and colonial history should no longer determine who gets the fish.”
—Derek Wall (b. 1965)
“Fashion is the most intense expression of the phenomenon of neomania, which has grown ever since the birth of capitalism. Neomania assumes that purchasing the new is the same as acquiring value.... If the purchase of a new garment coincides with the wearing out of an old one, then obviously there is no fashion. If a garment is worn beyond the moment of its natural replacement, there is pauperization. Fashion flourishes on surplus, when someone buys more than he or she needs.”
—Stephen Bayley (b. 1951)
“A submissive spirit might be patient, a strong understanding would supply resolution, but here was something more; here was that elasticity of mind, that disposition to be comforted, that power of turning readily from evil to good, and of finding employment which carried her out of herself, which was from Nature alone. It was the choicest gift of heaven.”
—Jane Austen (1775–1817)
“It is the international system of currency which determines the totality of life on this planet. That is the natural order of things today. That is the atomic, and sub-atomic, and galactic
structure of things today. And you have meddled with the primal forces of nature! And you will atone! Am I getting through to you, Mr. Beale?”
—Paddy Chayefsky (1923–1981)
