Many studies have shown that economic conditions affect energy intensity.As a fundamental component of macroeconomics, business cycles are a fundamental factor in energy intensity.The present study examines the asymmetric effect of business cycles on energy intensity in Iran in the period 1972-2020. In order to analyze the relationships between the variables, Nonlinear Autoregressive Distributed Lag (NARDL)was used.The results of the model show that in the short term, the impact of the negative impulse of the business cycle on the energy intensity has a negative effect until the first break and then a positive effect until the third break, while it is positive in the long term. But the positive impulse to the business cycle in the short and long term has a negative effect on energy intensity. Also the results show that the coefficients related to the logarithm variable of OPEC oil price in the short and long term are positive. But the short-term and long-term coefficients of the logarithm of the industrial structure index show that energy intensity decreases by 0.12%and increases by 0.04%in the short-term and long-term, respectively.Finally the results of Wald's test show that the effects of positive and negative impulses of business cycles on the energy intensity index are asymmetric in the longterm,but in the short term, this effect is symmetrical.Recognizing business cycles can lead to correct decision-making by policy makers in the development of the energy industry and at the same time, it can effectively prevent and even reduce the excessive growth of energy intensity

Attention to water resources and consumption in Iran's industrial sector is important due to the existence of severe tensions in the country's water resources. Therefore, the purpose of this study is to evaluate the virtual water trade in the oil industry of Iran. For this purpose, the technical-basic approach has been used to measure virtual water and the special water demand and virtual water trade of Iran's oil sector has been calculated from 1978 to 2019. The results show that due to the high volume of oil exports, Iran is a net exporter of virtual water. The amount of water consumed in the oil industry and the process of extraction and production of crude oil in the years under review averaged 594 million cubic meters per year and the amount of virtual water that left the country following the export of crude oil in these years averaged 356 million cubic meters per year. Also, the export value of virtual water in the oil sector has a value of 1838 thousand Rials per cubic meter. To manage the country's water resources and the leading crises in this sector of the industry, it is possible to greatly increase water efficiency in this sector by modifying production processes and updating equipment, facilities, and methods used to optimally consume water in this sector.

The impact of technological advances on energy consumption is one of the topics that has been considered by many researchers and policymakers. Numerous researchers have tried to evaluate this relationship based on various technology indicators. The index of economic complexity is one of the new indicators that has been used in recent years to measure the level of knowledge and technology in the production structure. In this paper, the index of economic complexity along with energy prices and GDP have been used as determining factors of energy consumption in Iran during the period 1976 to 2018. Quantile regression results show that the coefficients of the variables are different in the deciles. The impact of economic complexity on energy consumption in all deciles has been positive, indicating the dominance of the rebound effect on energy consumption. Price elasticity is less than one in all deciles and less in the higher consumption deciles. In contrast, the income elasticity of energy demand was higher in the upper deciles

There have been many studies on economic sanctions and the effectiveness of these sanctions. In these studies, the sanction variable treats as one or two dummy variables (binary), to indicate at most four levels (no sanctions-mild sanctions-severe sanctions-comprehensive sanctions). Studying the effectiveness of economic sanctions requires recognizing the extent and severity of sanctions in various sectors, so it is not possible to examine the effectiveness of sanctions and any review of economic sanctions independent of the severity and extent of sanctions. To this end, in this article, we present the severity of sanctions imposed on the energy sector to a variable between zero to five to provide a better indicator to understand the pressure of economic sanctions imposed on the energy sector of Iran. We examine the effectiveness of sanctions by entering the sanctions severity variable on Iran's foreign trade with five major trading partners, including Germany, China, India, United Arab Emirates, and Turkey, based on the gravity equation through an interactive dummy variable method. We tried to present all the sanctions imposed on Iran's energy sector, between 1992 and 2018. The results show a significant and negative effect of the intensity of energy sector sanctions on Iran's foreign trade. China and UAE have the lowest response to sanctions on Iran’s Energy sector. Also, the highest reduction of trade with Iran due to energy sector sanctions is dedicated to India and Germany.

Investigating the relationship between oil revenues and financialization in countries with abundant natural resources is particularly important. Considering the dependence of Iran's economy on oil rent, this paper examines the effect of oil revenues on financialization. The simultaneous equations system approach and time series data for 1979 through 2018 were used to analyze the relationship between variables. The research findings show that oil revenues positively and significantly affect financialization. Also, economic growth, human capital, and institutional quality have a negative and significant impact on financialization. But, physical capital and inflation impress positive and significant effects on financialization. Therefore, oil revenues along with the low quality of institutions, extensive sanctions, and oil price fluctuations conduct in an increase in rents and corruption, weakening of property rights, distrust of government policies, and an increase in speculative incentives. A rise in speculative incentives leads to the deviation of capital from the real to the financial sector; finally, the capital transfer to the financial sector also directs to an increase in financialization.

The green economy is a concept introduced in recent decades and has been defined as a framework for improving social welfare and justice by reducing environmental risks. Green growth has become the economic development strategy of many countries worldwide. In the meantime, FinTech can be effective in promoting green growth. Considering the development of FinTech in Iran, this article tries to examine the effect of the development of FinTech innovation on green growth in Iran. For this purpose, quarterly research data analysis was performed from 2013 to 2022 using the ARDL model. The results show that with a one percent expansion of FinTech services development, green growth will improve by 0.44 percent. FinTech innovation can reduce costs and improve the quality of financial services. It can also lead to green economic growth through green credit and green investment. Therefore, measures for systematization, integration, and synergy of Fintech services development to expand green investment and improve the environment can help improve green growth

In analyzing the efficiency of electricity distribution companies, according to the economies of scale hypothesis, due to the existence of natural monopoly properties, larger firms are expected to be technically more efficient (ceteris paribus). To investigate this issue, this study assessed the technical efficiency, economies of scale, and economies of scope of Iranian electricity distribution companies during 2011-2017 and examined their relationship with company size. For this purpose, the stochastic frontier analysis technique and the input distance function approach were used. The results show that technical efficiency first decreases and then increases with increasing company size. The results also show that economies of scale are present in most companies, although the use of economies of scale decreases as company size increases. Finally, economies of scope were observed in all the companies studied, and their magnitude decreases as company size increases. Therefore, it can be said that the hypothesis of economies of scale implying higher technical efficiency of larger companies, is not confirmed, although the necessary condition for the establishment of a natural monopoly is present in Iranian electricity distribution companies

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.

Pollutants emissions intensity in Iran which is mainly originated from energy consumption is higher than those of the global one. In this context, the current study aims at investigating emissions intensity determinants in the Iranian economy. To get the objective, decomposition analysis (index decomposition technique) was applied to decompose the energy intensity to its components. Then, the determinants of emissions intensity were examined using the regression model. The selected pollutants are NOx, SO2, CO, CO2. The data were related to 1367-96 (1988-2017). The results for all pollutants revealed that emission coefficient (emission per unit of energy) and energy intensity in services and manufacturing sectors have the highest contribution to emissions intensity. The findings suggested that the manufacturing sector plays a central role in SO2 emissions and a 1% increase in emission coefficient and energy intensity in the sector will increase emissions intensity by 0.6 and 0.5%, respectively. The services sector has a more important role in the emissions of the remaining pollutants and the corresponding values are 0.8% and 0.45-0.9%, respectively. Furthermore, urbanization could increase emissions intensity significantly. However, economy openness failed to affect emissions intensity significantly..

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.

Assessing the value of petrochemical industries on the one hand as strategic industries in the provision of raw materials of other parts and on the other hand, given the high weight of the formation of the stock market in Tehran, it is important. This industry, while influencing developments in other markets, especially the oil market, which has a significant impact on other markets, in particular the financial market. The stock prices of the petrochemicals in the stock market are heavily dependent on the price of petrochemical products, as well as the high dependence on oil price changes on global markets. Therefore, the analysis of the relationship between petrochemical price and oil price requires an asymmetrical model. In this study, the effect of oil price on value of the petrochemical industry in asymmetric shape in 2008-2017 periods daily basis has been analyzed using model Shin et al (2014). For this purpose, a nonlinear autoregressive distributed lag (NARDL) approach has been used. The findings indicate that these industries could be the channel for transferring global oil price fluctuations to the total stock market in Tehran. In the short term, anonymity is confirmed by the impact of the oil price on the value of the petrochemical industry. As oil prices decline, the value of petrochemicals decreases, but with increasing oil prices there will not be an increase in the value of petrochemicals. In the long run, oil prices are ............

With increasing competition in the wholesale Electricity markets and advances in behavioral economics in recent years, the multi-agent modeling approach has been applied widely to simulate the outcome of the markets. The electricity market consists of power generating agents that compete over production in daily auction conducted by an independent system operator (ISO). The market clearing mechanism can be seen as a static game that repeats every hour. In this game, an agent proposes her price for the next day and the ISO chooses the best proposals that minimizes the total costs given the demand and the technical constraints. Agents are also assumed to learn from the outcomes and adjust their biding strategy accordingly. In this paper, we develop an agent-based model for the day-ahead and pay-as-bid electricity market in Iran. The objective is to compare the outcome of the market measured by the agents profit and the time to converge using three different strategies: greedy, random and reinforcement learning. The simulation results indicate that the reinforcement learning leads to higher profits with a faster convergence rate than the other two strategies.

Since electricity distribution companies operate in various environmental conditions, their relative efficiency scores used for regulation purposes, should be corrected for environmental factors that could influence the underlying efficiency of them. This paper conducts efficiency correction for 39 Iranian electricity distribution companies applying two stage (DEA and Tobit) analysis in 2015. Accordingly, first to the efficiency performances of the electricity distribution companies are determined using DEA. In the second stage, the Tobit model is emploied to determine the environment factors which may explain the calculated efficiency scores. Based on the results, the rainfall level and the customer mix have negative and positive effects on efficiency of electricity distribution companies, respectively. Hence, the primary efficiency scores of DEA are corrected for environmental influences. The comparison of the primary and the corrected efficiencies indicate a significant changes in the efficiency scores and the ranking of the Iranian electricity distribution companies, such that the efficiency of companies with higher rainfall and lower industrial customers relative to their average, have increased, and vice versa.

Human capital is one of the most important inputs in production function that this factor has a crucial role in economic development process. Human capital in oil-dependent countries such as Iran could be affected by oil revenues as well as the form of distribution of oil rent. These evidences accompanied with contradictory and ambiguous impacts. The aim of this paper is to investigate the nonlinear impact of oil revenue on human capital in Iran during the period of 1975-2014. For this purpose, by using a threshold regression model, human capital has been modeled. The empirical results indicate that when the share of oil revenues in GDP is less than about 0.09, increasing share of oil revenues in GDP has a positive significant impact on human capital that the estimated coefficient is 20.21. But after the threshold level, increasing the share of oil revenue in GDP has a significant positive impact on human capital that the estimated coefficient is 5.37. Therefore, the intensity of oil revenue effect on human capital has been dramatically decreased in high oil revenue regime rather than the low oil revenue regime. Therefore, decreasing dependency to oil revenues increases human capital.

Development of renewable energy would help to achieve the goals of economic, social and ecological development which are considered as the most important factors in achieving sustainable development in each country. This article examines the impact of real economic growth per capita on the country's clean energy deals during the period 1967-2012 in Iran. To this end, the pattern Auto Regressive Distributed Lag (ARDL) and Co-Integration method are employed to determine the presence of short and long-term relations among the variables. The results show that the speed of adjustment is relatively high error correction model and the model is able to adjust the 61% of short-term imbalance error, to achieve long-run equilibrium. According to the corresponding estimations, the relationship between real economic growth per capita and renewable energy consumption, combustible renewable and waste consumption and electrical energy consumption in both short-term and long-term is negative. Also Long-term results have showed a significant negative relationship between electrical energy consumption, renewable energy consumption combustible renewable and waste consumption and real economic growth per capita. So, in long- term, increasing one percent consumption of the mentioned variables, cause to decrease the real economic growth per capita to 0.71, 0.72 and 0.79 respectively.

Fiscal regime is one of the main differences between petroleum contracts. Fiscal regimes in oil contracts are divided in two main categories namely Concessionary and Contractual Systems. In contractual systems, the main difference between service and production sharing contracts is the way of compensation of contractor services which could be in cash or in kind. In production sharing contracts the contractor receives a portion of produced oil. One of the main criteria to compare fiscal regimes is government and contractor takes in real values. Comparing the net present value of contractor take shows that PSC could have been more desirable and cost effective in Azadegan, Soroush & Norouz, Forouzan & Esfandyar oil fields than Buy-Back contracts.

Environmental tax and subsidy are two key instruments used in many countries to prevent environmental degradation and to achieve sustainable development. Using game theoretic approach, this paper develops and calibrates a model to determine optimum indirect environmental tax for Iran. More specifically, in the first stage the government sets green taxes and subsides, and in the second stage, the final goods and energy producing firms take these rates and choose their inputs. This dynamic game is solved by backward induction. Prior to our calibration, the production functions for fossil energy, renewable energy - as an intermediate goods - and final goods are estimated. The model is calibrated by using the Iranian data for the period 2015. The results indicate that the optimum green tax rate on fossil energy producing firm and final goods firm are 18 and 9 percent, respectively. These results have important policy implications for policymakers and social planners in Iran.

In spite the global efforts to reduce energy intensity; Iran’s energy intensity has been increasing during the recent decades. To get a more detailed investigation of energy intensity, this study aims at decomposing energy intensity into its components including efficiency and structural change as well as at examining driving forces behind Iran’s energy intensity components during 1973-2011. Energy intensity decomposition showed that efficiency changes accounts for the most of increased energy intensity. It is found in this study that income (GDP), capital- labor ratio and urbanization are the most determinants of energy intensity and its components. Regarding the non-linear relationship between energy intensity and driving forces of income and capital-labor ratio as well as the estimated turning points, income plays a significant role in increase of energy intensity while capital-labor ratio tends to induce a reduction in energy intensity. Although urbanization has a positive contribution to energy intensity via structural changes component, its dominant effect on improved energy efficiency leads to an overall effect of reduced energy intensity by more than 1.8% as 1% increase in urbanization. The results showed a limited effect for price and share of industry in GDP and left no significant role for economic integration and foreign direct investment. The corresponding value for these variables remain less than 0.05%. 1.0pt;line-height:85%;font-family:"B Zar";letter-spacing: -.2pt;mso-bidi-language:FA;mso-ansi-font-style:italic'>کار با شاخصهای شدت انرژی و نقطه عطف مترتب بر آنها در مجموع اثر درآمد در جهت افزایش شدت انرژی و اثر سرمایه در جهت کاهش شدت انرژی ارزیابی شد. اما شهرنشینی با وجود افزایش شدت انرژی از طریق تغییرات ساختاری از طریق بهبود کارایی در مجموع موجب کاهش شدت انرژی فراتر از 8/1 درصد به ازای 1 درصد افزایش شهرنشینی خواهد شد. اثر قیمت و سهم صنعت از تولید ناخالص داخلی بر شاخصهای فوق محدود و اثر متغیرهای شاخص ادغام تجاری و سرمایهگذاری خارجی قابل اغماض ارزیابی شد. رقم متناظر برای متغیرهای یاد شده بیشتر کمتر از 05/0 درصد به دست آمد.

Signing Oil Contracts with international oil companies for upstream and downstream operations in Iran's oil industry has a long history. After the discovery of oil, the first international oil contract was signed in Iran. Different types of oil contracts have been used in Iran. In most cases, the adequacy of contracts in terms of economic benefits has raised questions and ambiguities for Iran. To investigate this topic, the gas buyback contracts are evaluated from an economic point of view. In order to assess the results more carefully, these contracts are compared with the Production Sharing Contracts. Phases 2 and 3, and also 4 and 5 of South Pars Gas Field have been selected for this paper. Since these projects have been awarded in the form of buy-back contract, in addition of defining different scenarios, the Production Sharing Contract for the project has been simulated. After finding the best scenario in terms of the production sharing contracts for both projects, we found that for phases 2 and 3 of the South Pars, the Production Sharing Contract and for phases 4 and 5, the buyback contract, are proved to be more favorable for Iran.

The impact of information & communication technology (ICT) on people's lives can be study in different aspects. From economic and environmental perspective, the outcomes of the efficiency and productivity activities, has an important role because the improvement of efficiency provides a basis for reducing energy consumption .This Paper examines the impact of information & communication technology (ICT) on petroleum products in transportation Sector of the selected OECD & OPEC countries for the period 2000-2010 , and for this purpose ,dynamic panel modes are used. The results show that ICT has different rules in the samples. In the selected OECD countries, more use of information and communication technology can increase the intensity of consumption of petroleum products of the transportation sector, while in the selected OPEC countries more use of ICT can reduce the intensity of consumption of petroleum products of the transportation sector and ICT has the potential for reduction of energy intensity in the transportation sector of these countries that have high energy intensity.

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.

With regard to the ever-increasing need for energy in current societies to satisfy various requirements, scientists and researchers from different countries, such as Iran, have a basic approach in their agenda to achieve renewable energies. The scientists believe that with regard to the limited fossil fuels and their environmental pollutions, renewable and clean energies can be the first alternative to generate energy. Our country, Iran, has numerous capabilities in the field of generating new and renewable energies. This fact emphasizes the need for an optimum model to develop the use of renewable energies. In line with this objective the costfunction is chosenas the objective function. Given the potential and limits ofrenewable energy (resources Limited), Consumptionof electricpowerin each of16regions (apply Limited) confidencelimits of renewable energy (technical limitations), the model was designed and with use Robust optimization model was solved in LINGO software.The optimum of using renewable energies suggests the 36.71% generation of small hydropower energy, 18.22% wind energy, 17.19% biomass energy, 13.43% geothermal energy, 12.53% tidal energy, and 1% solar energy.

Oil revenues make up the major part of revenues of the oil exporting countries. So, the fluctuation of oil price is very important for these countries. This study investigates the asymmetric effects of oil shocks on output in Iran over the period of 1369:1-1386:6 using the Markov switching approach. The results suggest that the effects of oil shocks on output are separable into two regimes. In addition, the results also show that the effect of oil shocks over the recessions is significantly higher than that over the booms. In other words, the impacts of oil shocks on output in the Iranian economy over the booms and recessions are asymmetric.

This paper uses the growth model of Stokey (1998) extended by Deng and Huang (2009) to examine the dynamic relationship between output and environmental pollution in Iran. After solving the model and deriving the necessary conditions for sustainable growth path, the model is used to examine the presence of Environmental Kuznets Curve (EKC) for Iran. Using MATLAB software, the model is calibrated for the Iranian economy for the period 1959-2008. This allows us to find optimal paths for key variables. The result shows that that the Iranian economy is not on its optimal sustainable growth path. Moreover, simulation results indicate that there is a positive relationship between income per capita and CO2 per capita over time. Hence, we might claim that the Iranian economy is probably on its early stage of growth. In other words, Iran might still be on the negative part of EKC. In addition, our simulation result shows that there will be a threshold level for per capita income in which the quality of environment starts improving after this point. Hence, one might conclude that the EKC might be true for Iran.
