The dynamics of hyperinflation

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.
