The goal of this article is to test the empirical validity of the absolute version of Purchasing Power Parity (PPP) and Uncovered Interest Parity (UIP) to Brazilian data using the cointegration analysis developed by Johansen. The period covered by the sample was 1980:1 to 1994:2 (quarterly data). Some of the series used in this work are I(2) and the cointegration analysis become more complex. The methodology to treat this problem will be discussed briefly. The results of the tests are not favorable to absolute version of the Purchasing Power Parity. The results show that deviations from PPP are related to interest rate differentials.
