Abstract

T





he world economy has experienced a bulk of positive and negative shocks in crude oil prices and exchange rates over the years, and that global inflation has undergone some changes. Such shocks have affected the macroeconomic variables in the countries of the world and have challenged the economies of these countries, and have led them to take different measures to protect themselves against the devastative effects of these shocks. Accordingly, the main objective of the current study was to analyze the dynamic effects of three external shocks (global oil price shock, euro / dollar exchange rate shock and global inflation shock) as well as to investigate the appropriate monetary policy strategy for the Iranian economy, given the structural characteristics and patterns of external shocks. In so doing, we analyzed the responses of external responses to external shocks according to alternative monetary rules, including Headline Inflation Targeting (IT), Core Inflation Targeting (CIT), and Exchange Rate (ER) rule. Therefore, in this research, the goal was to determine the monetary policy rule to minimize both macroeconomic fluctuations and keep inflation at a low level. Furthermore, we strived to answer the question that whether the inflation criterion in Iran should be headline inflation, core inflation or exchange rate. To answer this question, using the DYNARE software, we estimated a multiplicative New Keynesian Dynamic Stochastic General Equilibrium model based on the characteristics of Iranian economy. Our primary finding showed that core inflation rule was the best monetary rule for stabilizing both macroeconomics and inflation.
