Modeling and analysis of macroeconomic system dynamics in MATLAB/SIMULINK environment

Abstract

The general theory of cyclic processes is examined in an economy. The simulation model of solutions of differential equations describing the cyclic vibrations of business activity and the trend curve of GDP growth is built in MATLAB/Simulink environment. Stability of the system is investigated. The graphic image of solutions of differential equations is brought, the influence of accelerator power on the dynamics of the economic system is analyzed.
