This paper shows evidence with respect to the Purchasing Power of Parity (PPP) hypothesis in twelve Latin American countries. The variance ratio statistic is used to gauge the stationary component in the real exchange rate, as well as the real exchange rate dynamics after an innovation occurs. In most of the cases, the results show that the real exchange rate can be modeled as a cuasi-stationary process with a significative mean-reverting component that cancel part of the shock. Therefore, the nominal exchange rate and/or the internal price index do not fully adjust to the inflation differentials. Thus, short run deviations from the PPP are no¡ completely offset in the long run. The expected real exchange rate stationarity suggested by the PPP was only found in two of the analyzed cases.
