The Relationship between Inflation Gap Persistence and Central Bank Monetary Policy through 1st to 4th Economic, Social and Cultural Development Programs in Iran

In this paper, the aim is to investigate the relationship between Taylor rule for monetary policy and inflation gap persistence in a simple new Keynesian model. This rule is a function of inflation and production gap specifying the weights to these two variables. By estimating these weights via a simultaneous equation system and seasonal data during 1368-1389, the relationship has been investigated between four development programs.According to the results obtained, inflation gap is not persistent in none of the development programs and so there is no significant relationship between inflation gap persistence and the weights of inflation and production gap in monetary policy. That is, the increase and decrease of persistence parameter is under the effect of economy structure of the country. Lack of a significant relationship indicates the imprecision of monetary policy implemented by Central Bank and the failure of the impact of this policy.
