| A Dynamic Macroeconomic Model with Time Lag in Investment Processes |

|
| Abstract: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. |
