Investigation and Evaluation of Monetary Policy Transmission Channels in the Economy of Iran

Monetary policy plays an important role in managing the economy, but success in applying this policy requires that the monetary authority understands the process of monetary transmission in the economy. Thus, it is not possible to study the effects of monetary policy on the economy without studying the channels of monetary policy transmission. Therefore, in this paper, the effect of a monetary policy through differ-ent channels of monetary policy transmission on inflation and production in terms of time process and extent of effectiveness by using Iran s data over the period of (1960 to 2018) through the method of new Keynesian dynamic stochastic general equilibri-um have been investigated. The accuracy of the model was confirmed by analysing the impulse-response functions and calculating the method of moments of the second order. The results of the model show that the effects of monetary policy shock are transmitted through the nominal growth rate of money, the real exchange rate on infla-tion and production without oil. Also, this effects by increasing the interest rates on bank deposits through the monetary base lead to increase production without oil, and through the monetary base, the exchange rate and the price index of domestic goods reduce inflation.
