Consequent to the financial crises, nominal feedback rules received considerable attention consideration from many of the monetary authorities in many countries. The innovation of these rules is a feedback mechanism that allocates precise adjustments to the monetary policy instruments where target variable deviates from its desired path. Mc Callum's rule can be taken as one of the most prominent feedback models in monetary economics. In the present study, the experimental behavior of the policymakers in the Iranian Central Bank will be investigated applying nonlinear Mc Callum's rule in the period of 1368:4 (1990:1) to 1396:4 (2018:1) using Markov-switching model. Considering that the Iranian Central Bank does not announce the precise production and inflation targets, the model estimation will be carried out based on the assumption of unobservable target variable. In this regard, for estimation of the two unobservable variables of nominal production growth and inflation, Bayesian Kalman filter will be employed. Then model will be stimated with markov switching approach in different rejime. The analysis of the model coefficients shows that the central bank during the recession assigned more weight to the nominal output growth variable and in the boom period more weight was assigned to the inflation gap variable. This illustrates the correct response of the central bank of Iran to these variables base of theoretical expectation. Therefore, in this paper and base on estimation results of nonlinear McCallum rule, the asymmetric behavior of the central bank with respect to the monetary reaction function is confirmed.

The study of the sources of exchange rate fluctuation is of great importance to the monetary authorities of a country. In the present study, Taylor and Mccallum rules are used to examine exchange rate fluctuations, including the impulses of oil, the impulses of risk premium, the impulses of supply, the impulses of demand, and the impulse of monetary policy in a structural vector auto-regressive framework in the period 1991:1-2017:4. The results of the shock reaction indicate that the exchange rate reaction to the impulses of risk, demand and monetary policy is positive but negative to the impulse of oil. This result is the same according to both Taylor and Mccallum rules, although there are differences in the size of the reaction. The exchange rate reaction to the impulses of supply is negative in the Taylor model and positive in the Mccallum model. The results of variance decomposition also show that, in the Taylor model, the demand and monetary policy shocks, and, in the Mccallum model, the risk premium shock have the largest share in the exchange rate fluctuation. In this study, Taylor and Mccallum models are compared, and it is concluded that the Mccallum rule is more powerful than the Taylor rule in Iran's economy to control the impulses. Indeed, due to the fixed interest rate system, the interest rate mechanism is not effective in the Iranian economy, but the liquidity control policy is a rational policy.

Economists have reached a consensus that an independent central bank could improve its policy efficiency by following a monetary policy rule. One of the important rules is McCallum rule where that requires central banks to target the growth rate of nominal GDP using the monetary base as its instrument. One of the features of the McCallum rule uses the monetary base rather than the interest rates as the monetary policy instrument that is consistent with the Interest-free banking system in Iran. This paper utilizes a counterfactual simulation method to evaluate the feasibility of McCallum rule as a policy guideline for Iran in two simple macroeconomic models. The simulation results show that following the McCallum rule could significantly reduce Iran’s nominal GDP fluctuations. The analysis shows that rule-specified path for the monetary base changes could be used as a benchmark for the Central Bank of Iran policy decision.

Inflation targeting is a monetary policy system that the central bank independence, the absence of fiscal dominance, the determinate and unique target and the efficient outline for prediction of inflationa are its requirements. However the target should be determine and checked by the monetary strategy. Also in successful countries to reducing inflation, structural reforms in economy such as public and banking sectors, have had an important role.
Meanwhile the investigation of other countries experience in regards inflation targeting, the study tries to suggest a monetary policy rule that its coefficients are time-varying. Hence using state space model and Kalman filter, the study tries to investigate Taylor and McCallum rules for Iranian economy during 1378:01-1393:04 which their coefficients are time-varying.
The results show that the monetary policy according to Taylor's and McCallum’s time-varying rules has respond to inflation and exchange rate changes and the non-time-varying coefficients such as GDP gap, dummy variable and the lag of policy variable.

The most important objectives of monetary policy are to provide price stability, economic growth and favorable employment levels. Since achieving these goals is not directly accessible for policy makers, so introducing and studying the appropriate tools and intermediate targets seem necessary. For this reason, this paper tries to answer this question: Whether can we introduce an appropriate rule/procedure as monetary policy [or not]. Therefore, this paper applied the well-known procedure of McCallum [a rule based on the optimum monetary rate] as well studied its fitness with the economic system of Iran over 1984-2013 by the use of GMM method. The results show that the defined optimum path by McCallum procedure [for the monetary growth rate] can be accounted as the appropriate strategy for the monetary policy in Iran and the economy of Iran can use it as a proper benchmark in its policy decisions.
