Over the past decades, the economies of the world have continually experienced economic fluctuations, business cycles, and cycles of boom and recession. Fiscal rules are one of the most important tools of the government with the goal of stabilizing and reducing fluctuations during the business cycle. It is always the minds of many policymakers who are involved in the question of how a policy should be considered during a period of boom or recession. In fact, policy makers are confronted with the question of whether fiscal rules should be used during business cycles. In response to this question, the present study uses a dynamic stochastic general equilibrium (DSGE) model and modeling the National Development Fund to scenario in two modes of applying counterycyclical fiscal rule and its non-implementation. The findings of the study showed that, in the case of petty impacts, a counterycyclical fiscal rule based on oil revenues has reduced the intensity of fluctuations of macroeconomic variables compared to the absence of a fiscal rule. Also, in the case of monetary impulse, there is a significant difference in the effectiveness of the implementation of the fiscal rules there is no indication of its non-application.
