Delayed Keen Model with Inflation
Keen's model describes the dynamics between wage share, employment rate and debt ratio. In literature, the model was extended to represent the effects of inflation and also the speculative money flow. Based on the inflationary model, we take into account a time delay in the inflation term which stands for the period before the effects of inflation are seen. We observe that, the delayed system may experience a Hopf bifurcation and exhibit cyclic behavior around an equilibrium point, although the non-delayed model is stable under the same conditions.
