This paper uses the solution of the linear difference model under rational expectation of Blanchard and Kahn (1980) to test the validity of the inflation stickiness and the Rational Expectation Hypotheses for the Brazilian economy during the period from 06/95 to 09/02. Using the Fuhrer-Moore model and GMM we find evidence favoring both hypothesis.
