Application Study on Signal Analysis of Multiplier-accelerator Model
As it is difficult to solve the system of difference equation of multiplier-accelerator model, it is difficult to thoroughly and comprehensively analyze the effect of typical macro economic model on economic parameter, and the accuracy of model is diminished. In this paper macro economic typical model proposed by Keynes is analyzed by signals and system theory, model is analyzed from a systemic perspective, so effect of system parameter and input signals on macro economic operation can be clearly analyzed. Through analysis of system structure and system response characteristic, effect of system parameter on economic operation can be determined. Calculation result shows that series drawbacks which occur while model is directly analyzed by matrix theory in t raditional way is conquered by this new method, and accuracy of the model is improved. Deciders can refer to the study result.
