Air pollution concerns, climate change, and sustainable development necessitate the discussion of the dynamics of energy intensity. Nowadays, energy convergence is widely used as a tool for considering the dynamics of energy intensity. The energy intensity convergence in manufacturing industries is suitable to assess whether there is a knowledge spillover between manufacturing industries and whether government policies have been effective for reducing energy intensity in manufacturing industries. The purpose of the study is to examine energy intensity convergence in Iranian manufacturing industries. To do that, we collected data from nine manufacturing industries from 1995 to 2015 and employed the generalized method of moments in panel data (GMM) technique. The results of the model estimation show that there is convergence of energy intensity in the manufacturing industries.

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.

The main goal of this paper is to study the effect of social infrastructure on economic growth in a recourse-based economy. To this end, we introduce the quality of social infrastructure into an endogenous growth model. The set up allows us to see how the resource abundance can influence the quality of social infrastructure and hence economic growth. We use optimal control theory to solve the model. The analytical solution shows that the impact of non-renewable resources on economic growth depends on the models' parameters. More specifically, we find out that if natural resource abundance leads to deterioration of social infrastructure, it might offset the positive impact of natural resources on economic growth and even might result in lower economic growth rate. We finally calibrate the model for Iran as an energy-rich economy. The calibration results indicate that in order to achieve 8 percent average growth rate, the quality of social infrastructure should improve by at least 4.3 percent. Moreover, when we ignore the quality of social infrastructure, the optimum economic growth rate is found to be 6 percent. This shows that it is important to take into consideration the role of social infrastructure in estimating long run economic growth for Iran. The result of sensitivity analysis indicates that one percent improvement in the index of social infrastructure results in 0.42 percent increase in equilibrium growth rate in Iran. This finding has important policy implications for policymakers and social planners in Iran.

This study investigates the impact of oil price volatility on macroeconomic variables such as investment, unemployment and production based on quarterly data during the period 1386:4-1369:1. To achieve this, permanent and transitory volatility of OPEC oil price estimated by component GARCH model (CGARCH). Then, using the Impulse response function, the impact of permanent and transitory volatility of oil prices on macroeconomic variables has been analyzed. The results indicate that permanent uncertainty arising from changes in oil prices has led to decline investment and production and to rise unemployment. And the impact on these variables is permenant. It is indicated that investment and production has declined and unemployment has increased due to oil price uncertainty and this process is accompanied by a high volatility.
