In this study the effects of levying various green taxes (base, 5%, 10% and 20%) on Iran’s fossil energy consumption (oil gas (OG), natural gas (NG) and gasoline (GA)), pollutant gas emission and social welfare was studied using a Recursive Dynamic Computable General Equilibrium (RDCGE) model. In order to RDCGE calibration, the Iran’s social accounting matrix (SAM)) and base scenario was used. Required data was gathered from central bank of Iran (CBI), Iran’s statistic center and ministry of energy during 2008-2016 seasonality. Also, for data analyzing Matlab software was applied. Results indicate that in while increasing green tax, a positive shock of economic growth (1%), reduces the increasing trend of OG, NG and GA. Also, levying 0% and 5% green tax couldn’t make the consumption of mentioned energies efficient, levyeing 10% green tax makes the consumption of NG and GA efficient and levying 20% green tax makes the consumption of mentioned energies efficient. In addition, while increasing green tax, a positive shock of economic growth (1%), reduces the increasing trend of gas pullotants emission and in orther to decreasing gas pollutants emission during economic growth, 10% green tax should be levy. Finally, while increasing green tax from 0% to 5%, 10% and 20%, a positive shock of economic growth (1%) increases the social welfare, less than 1%, more than 1% and less than 1%, respectively. Therefore, between studied scenarios, levying 10% green tax is the best for increasing social welfare.

This paper investigates the effects of trade liberalization and economic growth on non-oil bilateral trade balance of Iran and China over the period 1981-2012. For checking the stationarity of the variables and validity of the obtained results, the Augmented Dicky-Fuller test (ADF) and Perrone structural break test is employed respectively. To estimate the coefficients of the variables, ARDL model has been used. Using the framework of Oskooee and Brooks model, the findings of this paper show that increasing trade liberalization in short run and long run causes trade deficit for Iran. It means that from the view of demand side economists, higher trade liberalization deteriorates the trade balance of the country. Also, based on the obtained results, economic growth in both short run and long run has negative effect on non-oil bilateral trade balance of Iran and China. In addition, the real exchange rate has positive effect on the trade balance of Iran. It means that depreciation of national currency improves trade balance of Iran.
