摘要
In this article, we will show the Kaldor-Philips business cycle model with Hopf bifurcation theorem of the three dimensions, and the International trade model along with the dynamic IS-LM model by utilizing Hopf bifurcation theorem of the four dimensions. In section 2, we will present the Kaldor-Philips type dynamic IS-LM model. In section 3, we will also the dynamic IS-LM-international trade model of Hopf bifurcation theoremof four dimensions. In the last, but not least, I will present the policy implications of the Kaldor-Philips business cycle and International trade models along with the dynamic IS-LM model.
