Abstract In this paper by using a dynamic stochastic general equilibrium model we study how macroeconomic variables are affected by different shocks using fiscal reaction functions for Iran’s economy. For this purpose we compare the results of a real business cycles model in a baseline scenario, in which the government does not follow any specific reaction to the shocks and alternatives in which the government reacts counter and pro cyclically to the shocks. Results of the simulations indicate that when the government follows backward looking fiscal rules the deviation of the variables from steady state increases. In other words, in a real business cycle model for the Iranian economy, we show that the consequence of the government’s intervention in the economy is economic instability in Iran.
