The purpose of this paper is to investigate the relationship between the inflation and inflation uncertainty in Iran. Using mixed models of self-exciting threshold autoregressive (SETAR) and generalized autoregressive conditional heteroskedasticity (GARCH), the inflation behaviors are examined for the period 1990M05-2013M10. This approach allows testing the hypotheses of Friedman-Ball, Pourgera...

today, the discussion of regularity monetary policy in achieving inflation and output gap stabilization is important. in this paper, we investigated the persistence of the output gap in iran economy and then by using a hybrid new keynesian model based on quarterly data for 1990:1- 2011:3. we compared three alternative instrumental rules in monetary policy for iran economy. the results indicated...

The purpose of this study is to investigate the impact of exchange rate misalignment on inflation persistence. For this purpose, Vector Auto Regression method and Markov Switching model is used for quarterly data during 1989:4 -2014:3. The results show that, the impact of liquidity growth and exchange rate misalignment on inflation persistence is positive. On the other hand, GDP growth has a ne...

The aim of this study is to examine the nonlinear effects of fiscal and monetary policies on inflation during 1990:3 to 2013:1 based on threshold model. First lag of the liquidity growth is recognized as threshold variable with threshold value estimated at 6.37 percent. In low liquidity growth, the results indicate that inflation expectations and the lagged liquidity growth are the most importa...

in this paper, by using dynamic stochastic general equilibrium, optimal monetary rule derived for central bank of iran. monetary transmission mechanism of the model includes four equations, aggregate demand, aggregate supply, oil price and taylor rule. we have proved that dynamic structure of aggregate demand relation, regarding monetary inflation in iran, is a function of money growth rate. wi...

What measure of output, if any, should central banks target in simple interest rate rules? This paper analyzes the welfare consequences of responding to different measures of real economic activity in simple interest rate rules in a conventional New Keynesian model. Responding to the level of output is always welfare-reducing, while reacting to the level of the output gap reduces welfare if cos...
