Abstract

The aim of this article is to determine the optimal monetary policy rule when there is oil revenues shock by new Keynesian dynamic stochastic general equilibrium model through Bayesian approach with emphasis on Home Bias in Consumption. In this study, household consumption is divided into two parts; consumption of domestic goods and the consumption of the imported goods. After specifying the model, the parameters of proposed model are estimated using Bayesian methods and real data where Optimal Monetary Policy will be the policy which makes the welfare loss function minimized. The results show with the entrance of oil revenues shock, Optimal Monetary Policy is the central banks’ response to the inflation and exchange rate gap. By increasing Home Bias parameter in the model, welfare loss in all the policy rules is significantly reduced. The policy recommendations of this study are that, with exogenous shocks (in particular oil revenue shock) to the economy, in addition to inflation targeting, the exchange rate should be considered by central bank.
