摘要

This paper evaluates the inertial inflation hypothesis for Brazil. The hypothesis posits that indexation created a feedback mechanism such that one-time supply shocks were fully transmitted into permanent changes in inflation. A theoretical model is used to show that this outcome is based on the assumption of perfect price flexibility. However, with price stickiness indexation does not produce inertial inflation. The degree of inertia is then compared for two periods: one without indexation (1945-1963), and one with indexation (1969-1985). Finally. vector-autoregressive representations are estimated for the latter period, allowing lot price stickiness. The empirical results do not support the hypothesis.
