Abstract

A hyperinflation model is developed where the money and goods markets clear
instantaneously, expectations are rational and there is inertia in the price system due to
wage indexation mechanisms. The model is described by a nonlinear system of differential
equations and Hopf bifurcation theorem, regarding the public deficit as a parameter, is used
to study the dynamic properties of the system. The dynamics of the model is capable of generating
hyperinflation processes, as well as other paths that are commonly observed in high
inflation countries.
