Mathematical analysis of a spatiotemporal dynamics of a delayed IS-LM model in economics
The purpose of this research is to suggest and analyze a spatiotemporal of an IS-LM model with two delays, interest rate, liquidity preference and general investment function. The first delay into the proposed model refers to the time delay between the decision of investment and his implementation. However, the second one represents the delay in investment production. The well posedness of the model is proved. The stability analysis and the existence of Hopf bifurcation are obtained. Furthermore, numerical examples that confirm the analytical results are shown.
