投资过程中具有时滞的一类动态宏观经济模型

根据Klecki思想,对投资过程中具有常数时滞的一类动态宏观经济模型进行了讨论.通过选择时滞作为Hopf分歧参数,当时滞经过临界值时周期行为产生.并用数值例子解释了理论结果.

A Dynamic Macroeconomic Model with Time Lag in Investment Processes

This paper discussed the dynamic macroeconomic model with constant time delay in investment processes according to Kalecki''s idea. By choosing time delay as the Hopf bifurcation parameter, it is found that a periodic behavior occurs when time delay takes certain critical values. Numerical simulations were then provided to verify the theoretical results.
