  It is more likely that the monetary policy in Iran is discretionary and not based on a rule or a target. Besides, what is clear is that there have been explicit targets for inflation and economic growth in all five-year development plans (except the fifth plan). However, the question is that do policy makers observe the targets of development plans? Using an adjusted New Keynesian DSGE model for Iran, in this study we investigate the monetary policy under fiscal dominance and implicit inflation targeting of Iran. The results show that in most plans monetary authorities do not observe the explicit targets of five-year plans. The estimated monetary reaction function is only able to explain the period 2001-2011. The other result is that implementation delays of public projects have considerable effects on output and private consumption.

After the imposed war, Iran's economy has seen two relatively successful experiences in controlling inflation. These two periods include the final years of the Third Development Program and the Joint Comprehensive Plan of Action (JCPOA) term. This is while we are seeing a relatively high inflation rate in other periods. In this paper, based on literature on monetary rules and using a Time-Varying Parameter Bayesian Structural Vector Auo Regressive (TVP-BSVAR) Model with stochastic volatilities, we study a rule-based monetary policy or a systematic monetary policy and a non-systematic monetary policy (based on the stochastic volatilities of monetary shocks). The results indicate that in addition to the systematic monetary policy obtained from the model, the success of monetary policymakers in controlling inflation is not only due to inflation control per se (thst is systematictic) but also for non-systematic reasons such as fiscal policy through fiscal discipline and oil revenue management by both monetary and fiscal policymakers that does not fit into the framework of systematic monetary policy.
