The Role of Structural and Exchange Shocks on Macroeconomic Variables Dynamics

This paper has investigated the effects of structural and exchange shocks on the macroeconomic variables by using a DSGE model. In macroeconomic dynamics, three assumptions had made. First, economy faces nominal rigidities, second, because of fiscal dominance in Iran, defining monetary policy is not possible, and third, Iran economy is an small open economy that its macro variables have been affected by exchange shocks. In this way and by using quarterly data in the 1369-91 period, model parameters has estimated and the results show the effectiveness of real exchange rate, law of one price gap, and nominal exchange rate on inflation and economic growth. Moreover, based on simulation results, exchange rate fluctuations cause change in the equilibrium path of inflation and output.
