بررسی مقایسه‌ای اثرگذاری سیاست‌های پولی و مالی بر اقتصاد ایران در قالب یک الگوی DSGE

In this research, the effect of monetary and fiscal policies on the macroeconomic variables of Iran is compared. changes in money supply as monetary policy and changes in government spending as fiscal policy have been investigated on Iran's economy. The research has been done in the framework of a new Keynesian dynamic stochastic general equilibrium model using time series data during 1979-2013. The economy's general equilibrium contains 15 equations which have been extracted from behaviors optimization of households and firms besides government and Central Bank policy rules. Estimation of the parameters of the model was carried out using the Bayesian method and calibration. The results showed that the shock of increasing money supply would increase production, investment, employment, and inflation. Also, the shock of rising government spending has increased production, employment and inflation, but it also reduces private investment. Results indicate that the impact of government spending shock is more than the money supply shock. Also, durability of government spending shock is more than the same in money supply shock.
