This chapter illustrates the dynamic properties of the HRL formulation by means of a detailed numerical example based on the hyperinflation observed in Zimbabwe between 2000 and 2008. It first presents the results of dynamic equilibrium and dynamic disequilibrium simulations. It shows that the perceived rate of inflation converged asymptotically toward the instantaneous rate of inflation. This asymptotic convergence happens because the rate of memory decay grows exponentially and the elasticity of the perceived rate of inflation with respect to the instantaneous rate of inflation converges toward unity. The duration of the memory of inflation is also computed, along with the distribution of forecasting errors in the HRL formulation. Finally, the chapter examines how the HRL formulation sheds light on what Charles P. Kindleberger calls “some historical puzzles in macroeconomic behavior”.Less
