Oil prices and export revenues have an important role in exporting countries. A fluctuation in oil prices leads to imbalances and economic crisis in these countries. In this study, we analyze the effects of oil price fluctuations in the energy consumption of OPEC countries for the period 1998 to 2013. For this purpose, the panel data and generalized method of moments (GMM) is used. In this study, using EGARCH model, estimated the effect of fluctuations in oil revenues on three sub-energy, including oil, gas and electricity consumption. Then, analysis is continued on the symmetry or asymmetry effects of oil revenue by GJR model. Results show that fluctuations had different effects in this country. As in oil revenue fluctuations model on crude oil consumption, this fluctuations effects, except, the Algeria, Iran, Libya, United Arab Emirates and Venezuela in other countries were symmetrical. The other result shows that in country with asymmetric fluctuations, the negative oil price shock has larger impact.

Fluctuations in oil revenues are one of the most important economic issues in oil producing countries. Sound fiscal and monetary policy to soften the effects of exogenous fluctuations in oil revenues in the domestic economy has been a controversial issue in economic policy-making bodies. The main purpose of this study is investigating the effects of oil revenue on liquidity in Iran during 1990-2012 using Engle (2002) dynamic conditional correlation method. As this method assumes correlations varying during time, it makes it possible to enhance the analyzing power of phenomena during studied period Such as wars, business cycles, economic, political, and environmental phenomena. The results show that despite the volatile nature of the relationship between oil revenues and liquidity, correlation between these two variables has been always positive. That is, oil with the severity of different impacts, has always been one of the factors increasing liquidity.
