Oil revenue can play an important role in the economy of Iran. Oil revenues are the main source of government expenditure and exports. On average about 60 percent of government revenue and about 80 percent of Iran’s export income comes from oil and gas. Because of the importance of oil income shocks on macroeconomic variables such as economic growth, government expenditure, investment and liquidity, in this paper these effects have been investigated. We use quarterly data from central bank of the Islamic republic of Iran for the period of 1990-2010 and the method of vector auto regressive model (VAR) has been used. The results indicate that oil revenue shocks have major effect on these macroeconomic variables.

Trade openness, economic growth and environment are known as the major issues in recent decads. We considered the effect of expanding trade and economic growth on environmental quality for 11 country in the Middle East during the period of 1980 to 2010. Panel data econometric method and STATA software were used. Econometric tests confirmed fixed effects model among the pooled, fixed and random effects models. Each Arellano-Bond GMM regression model and Newey- West with 5 lags allowed were estimated beacuase of dynamic panel data and their results were compared with the results of fixed effects model and then were evaluated. We found per capita income has a significant positive impact on environmental pollution but further rise in income will reduce environmental pollution. Trade openness has negative effect and there is a non-significant effect on environmental pollution.
