In this paper, by using a model of the new Keynesians, we investigated the role of the central bank's accountability to shocks that causes deviations in the performance of the monetary policymakers. For this purpose, we used quarterly data for 69: 1 to 93: 3, and estimated the basic equations of the new Keynesians model. Then, By calculating the optimal values for the central bank's accountability to the two potential sources of deviations from the goals of economic stability and deviation of commitment to rules, we compared the loss of central bank to the loss of social. The results showed that the degree of central bank's accountability to commitment an instrumental rule is less than the degree of the accountability to achieve the goals of economic stability. Also, the central bank with applying Reforms in the implementation of its policy by optimal response to both types of deviations can be close to the results of the welfare society.
Then, in order to compare the importance of accountability of the central bank to achieve both goals, we considered two cases. The results showed that in the period of study in Iranian economy, the main objective of monetary policymaking has been more focused on stability of the economic goals but, the importance of commitment to follow an announced rule and accountability to that rule is too low, so that, it had no impact on the welfare function of the central bank.
