Monetary and fiscal policies are channels that government through them affects the macroeconomic variables, such as production, employment, investment, consumption, export, import and general price level to promote economic development and economic growth.
In this study by using the macroeconomic model and system dynamic methods, we try to analyze the effect of government consumption and investment expenditure on the economic growth and macroeconomic variables. There are four sectors that constitute the structure of the model, namely: Production, Monetary, Government and Foreign Trade sectors. Each sector plays special role in the model and affects the economic growth directly or indirectly. Each sector contains several subsystems that interact with each other.
The economic theories are basis for specifying structural equations. The equations are estimated by ARDL method. The model contains two types of long run equations and dynamic short run equations. All variables are simulated in the model, for 10 years from 1375 to 1385. Then validity of the model is evaluated by the statistical criteria.
Simulation results show that an increase in government investment spending has more effect on GDP growth, than government consumption, during the simulation period. When government deficit is financed through borrowing from central bank, it still has less effect on economic growth, during the simulation period.
