In the present study, the approach of a recursive dynamic computable general equilibrium was used in order to simulate the economic and welfare effects of the allocation of oil revenues in the Iranian economy. Accordingly, changes in the production index of different economic sectors, changes in consumption and price levels in the form of 4 scenarios of different combinations of depositing oil revenues to the National Development Fund of Iran, and using the social accounting matrix (SAM) related to the year 2011 were considered. The results showed that by using different scenarios of oil revenue allocation, the highest growth of production and consumption of the studied sectors compared to the basic scenario of the fourth scenario (save 20% of oil revenues in the country's foreign exchange fund and invest 30% of the fund's resources in the industry) will be. Meanwhile, the highest rate of price reduction in the production sector is related to the fact that 20% of oil revenues are saved in the country's foreign exchange fund and no amount has been invested in the economic sectors. In fact, the increase in production and boom is due to the increase in investment in the industrial sector of inflation and will lead to the growth of prices of manufactured products. Therefore, by allocating the fund's resources in the industrial sector, the goal of economic growth and increasing household welfare will be achieved. In fact, due to the strong links between the industrial sector and other sectors, including agriculture and services, by investing to improve the productivity of the industrial sector, all economic sectors have benefited from this issue and by increasing production while growing demand for investment and increasing household consumption will bring greater welfare to consumers.

The main objectives of the present study were evaluation of the economic, welfare and environmental effects of applying Feed-in tariff policy in the Iranian Economy. In this regard, the E3 type of hybrid recursive dynamic model was studied. Therefore, the model is used for the period of 1390-1404, to evaluate the effects of FIT policy under two different scenarios, similar and different guaranteed purchase price, in order to achieve 10% share for renewable energy in total electricity production in 1404. The result shows that in in both cases, pollution and its social cost reduction has been mainly caused because of the reduction in the sectorial GDP. Therefore, a definitive statement about the selection of a proper policy depends on the environmental purposes of the country.

The main purpose of this paper is to determine the amount of subsidy required to promote the share of renewable energy in total electricity production. To do so, different scenarios have been studied by a hybrid approach of Computable General Equilibrium model. The results have been created by entering the details of technology-specific information for electricity generation into this model. The result of codification and calibration of the model shows that in the case of applying same subsidy to achieve 10 present shares of renewable energies in total electricity production, there is a need for 851 percent subsidy rate. Although in this case the wind energy is the only activated resource and the solar and biogas sections have not succeeded in achieving any rise in production rate. The other scenario was based on the unequal subsidy, proportional to disadvantage of different renewable energy. The result shows that, to achieve a balance growth of 4 percent energy productions from renewable sources, the rate of subsidy for wind energy should be 887 present. This rate for solar is 1776 present and for biogas is 1585 present. So, in the first scenario, the proper tariff for purchase of electricity from renewable energy is 4100 Rials per kWh. This tariff in the second scenario is 4260, 8520 and 7600 Rials per kWh respectively.
