Abstract
The fluctuations in the oil price with uncertainty, as an exogenous variable, is the most important factor affecting the fluctuations in the GDP of the countries especially OPEC. This study examines the effect of oil price uncertainty on the Iran’s GDP growth using the seasonal data for the period 1988(1)-2011(4). The model used in this study is the asymmetric VARMA, MVGARCH-M and the estimated method is quasi maximum likelihood (QML). The results indicated that there is a negative and significant relationship between oil price and economic growth over the period. Furthermore, the results show that the conditional variance-covariance process underlying output growth and change in oil price exhibits non-diagonality and asymmetry.

Abstract
Monetary policy is one of the most important macroeconomic policies which could be used for achieving economic targets such as reducing the output gap and reducing the inflation's deviation from it's target level. These policies can be implemented through the control of volume of money or the rate of interest. Based on economic theories, the Central Bank should conduct monetary policies within a rule-based framework. In periods of positive or negative output gap or when inflation's deviation from it's target level is positive or negative, different monetary policies should be adopted. Assessment of Central Bank monetary policy's conformity to rules and the consistency of these policies with economic theories like Taylor's theory, is of vital importance. In order to evaluate the consistency of central bank monetary policies with economic theories, this study investigates the monetary strategies of Central Bank regarding the inflation's deviation and output gap during the period 1974-2013. It applies the Bootstrap method for this purpose. The result shows that Central Bank does not counteract the output gap during the periods of recession and boom and it's reactions to the inflation's deviation is in the reverse direction.
