Sound Fiscal Reactions to Stochastic Shocks: A DSGE Approach

Using a New Keynesian dynamic stochastic general equilibrium of Iran with price rigidity and imperfect markets, this paper shows how different stochastic shocks affect main macroeconomic variables in presence of variety of reaction functions. In this way, we compare the response of those variables to the shocks in baseline scenario (which the government does not perform any reaction) with an alternative; when government reacts counter-cyclically through back ward looking fiscal rules. Our findings was in favor of active counter-cyclical fiscal policy, by showing that the deviations from target values decrease when government reacts actively.
