However, in practice the real exchange rates exhibit twain short spring and long run deviations from this value, for example repayable to reasons illuminated in the Bala ssaSamuelson theorem. There can be mark ! differences between purchasing power adjusted incomes and those converted via market exchange rates.[4] For example, the creation Banks World Development Indicators 2005 estimated that in 2003, one Geary-Khamis dollar was kindred to about 1.8 Chinese yuan by purchasing power parity[5]considerably different from the nominal exchange rate.
