The main purpose of this study is to investigate the migration of bubbles from the oil market to the stock exchange. First, using the method of Phillips et al. (2015), bubbles were discovered and dated in the Iranian heavy oil market in the monthly period 1980-2020 and the Tehran Stock Exchange in the period 2008-2020. Then, using the method presented by Gomez-Gonzales et al. (2018), the migration of bubbles from the oil market to the Tehran Stock Exchange in the period 2020-2008 was investigated. The results showed that Iranian heavy oil has 9 bubble cycles in the period under study. Also, six bubbles were observed in the period under review for the Tehran Stock Exchange. The findings indicate the closeness of the ninth bubble in the oil market and the fourth bubble in the Tehran Stock Exchange. The hypothesis of bubble migration from the oil market to the Tehran Stock Exchange was tested in this period. The results of the hypothesis test indicate the acceptance of bubble migration from the oil market to the Tehran Stock Exchange.

The increasing population and rising demand for water and energy supply, along with the exacerbation of environmental pollution effects on natural and human resources, demonstrate the vital need for a cohesive movement toward the water, energy, and environment Nexus (WEEN). Since the electricity generation industry has a significant share in water and fuel consumption and CO2 emissions in Iran, in this study, the application of a combined renewable system in the Zarand Steam Power Plant was evaluated based on the Nexus approach. Solar system designing and carbon balance evaluation during plant lifetime was conducted via PVSyst software in 2021. Also, an environmental model of ReCipe was applied to evaluate the effect of carbon reduction on the ecosystem. The results have shown that replacement of at least 1% of the nominal capacity of the fossil power plant with renewable sources, will significantly prevent 1249/46 t CO2 emission annually in this power plant which is equivalent to 362/160 m3 fossil resources storage and 373/73 TOE.year-1 energy savings. Also, the results showed that in addition to protecting valuable natural resources, the combined cycle will lead to a significant reduction in water demand equivalent to 3660 m3 having the capacity of supplying underground water resources. Considering the benefits of saving water and energy resources and reducing carbon emissions, from the NEXUS approach, in addition to managing energy supply through replacing resources and using water and heat recovery technologies, applying energy demand management policies based on energy efficiency and its environmental effects is suggested..

The study of Iran's position in the international trade network of natural gas shows that although Iran is the second country with natural gas resources in the world and has a special position in the transit of natural gas, it is not an important player in the international trade network of natural gas. One of the most important issues for the development of international gas trade is to examine the possibility of exporting Iran's natural gas in the near future. The present study tries to estimate and simulate an econometric model including macroeconomic and energy variables, analyze the outlook of domestic demand and balance of natural gas in different conditions of Iran's macroeconomics, and assess the feasibility of exporting natural gas. The simulation of different scenarios for the period 2022-2032 shows three findings. Firstly, continuing the current policies result in the undesirable trend of the TFP at the macroeconomic level and economic inefficiency in the energy sector. Secondly, macroeconomic policy reforms in order to raise economic growth result in a negative natural gas balance. Thirdly, for the reduction of energy intensity, the energy price reform is not a sufficient policy, and emphasizing the non-price factors towards technical progress in order to rise energy efficiency is important. In addition, making an investment decision for infrastructure development of potential natural gas supply is important as a necessary condition.

The existence of a comprehensive model that enables the calculation of the real price of electricity production along with its environmental costs is one of the most important analytical tools in energy economics. It is now different from when virtual water costs and other environmental costs of power generation are taken into account. In this article, information from 56 power plants across the country was used. In this paper, an algorithm for calculating the Levelized Cost of Electricity (LCOE) is presented. Among these, common technologies in the production sector, including heating, gas, combined cycle, wind, and photovoltaic power plants, have been studied from an economic perspective and the results of calculating their cost price have been presented. The results show that the highest costs are related to electricity generation using gas technology (18.86 cents per kilowatt hour with subsidized fuel and 35.98 cents per kilowatt hour with exported fuel) and the lowest cost of generating electricity through a wind farm is 6.59 cents per kilowatt hour. In the calculations, the cost of fuel in the form of subsidies and exports and the cost of virtual water in the production process are also considered. One of the reasons for the slow growth of renewable energy development is that the fuel price of gas and oil for power plants in Iran was not realistic despite the fuel subsidy, so electricity production in thermal power plants is cost-effective and electricity production from renewable energies such as wind and photovoltaic power plants in a superficial view has no economic justification..

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.

Firm investment is one of the important financial decisions in the economy, which affects the value of companies and the wealth of shareholders, which can result in increasing welfare. Despite neglecting the effects of uncertainty in traditional investment theories, modern theories have introduced various mechanisms for the impact of uncertainty on investment expenditures. Using the daily data of oil prices and the data of 131 companies listed on the Tehran Stock Exchange market during the period of 2008-2020, the factors affecting the investment of the companies are identified by emphasizing the oil price uncertainty. For this purpose, in the first step, the stochastic volatility model in the framework of the space-state approach is the basis for estimating the oil price uncertainty, and in the next, according to the results of the Hausman endogeneity test, the instrumental variable method is used to estimate the coefficients of the variables affecting investment. The findings indicate that first, the volatility of oil prices has no significant effect on investment. Second, firm size, profitability, inflation, and Tobin’s Q affect investment positively and significantly. Third, the financial leverage, which is reflected in the capital structure polices, has a significant negative effect on investment, meaning that more focus on debt financing leads to less corporate investment expenditures.

This study examines the interrelationships of clean energy, domestic and foreign capital, economic growth, and environmental quality in a group of developing countries during 1995-2018. In this regard, the GMM method has been used. To estimate the impact of domestic and foreign capital development, three different indicators such as foreign direct investment, stock markets, and credits allocated to the private sector have been used. The results show that the increase in clean energy by one to two percent, the emission of carbon dioxide by four, and the increase of foreign direct investment by one percent have increased economic growth. On the other hand, economic growth, while increasing clean energy consumption by an average of 11 percent, has also increased carbon dioxide emissions. Despite the positive mutual relationship between clean energy and economic growth, fossil fuels are still used more in the selected countries. Clean energy projects have lower efficiency and higher financing than other energy supply projects. Therefore, in developing countries, due to a lack of enough capital, few investments are made in these projects.

Increasing global warming is the result of the gradual accumulation of greenhouse gases in the living environment. Energy production systems in general and electricity production in particular is one of the effective factors in the production of greenhouse gases. Therefore, on the one hand, environmental considerations and on the other hand, the limitation of fossil resources have made it necessary to change the energy production system and replace fossil fuels. In this regard, the use of renewable energy resources such as hydropower can be a good alternative to fossil fuels. This article has studied the effect of hydropower consumption on Iran's environment. Hence article has estimated the short-run and long-run relationship between hydropower consumption and different measures of environmental degradation including ecological footprint, carbon footprint, and CO2 emission in the Iranian economy during 1980-2018. For this purpose, the Autoregressive distributed lag (ARDL) approach has been used. The estimation of the specified models indicates the existence of a long-run relationship between the variables included in these models and shows that in the short and long run, there is a significant negative relationship between hydropower consumption and carbon dioxide emissions, and carbon footprints. In other words, the use of hydropower in the short and long run reduces the carbon footprint and emissions of carbon dioxide. Hydropower also affects the ecological footprint in the short run.

This study examines the correlation and causal relationship between energy carriers' consumption and Iran’s provinces' gross product for the period 1988-2017 using wavelet analysis with panel data and the Dumitrescu-Hurlin causality test. The results of correlation analysis show that the correlation pattern between energy consumption and GDP, in different energy carriers, is different. The correlation between natural gas, gasoline, kerosene, and electricity with GDP is strong at all energy intensity levels. The correlation between furnace oil and GDP is reported to be low and weak for all provinces in the long run. Furthermore, the findings show that in provinces with high energy consumption intensity, consumption of gasoline, fuel oil and total energy have led to GDP in the short run. In high-intensity cases, consumption of kerosene, gas oil, fuel oil and natural gas, in medium intensity all types of energy, and in low intensity, consumption of kerosene, furnace oil and gasoline have led to GDP. In provinces with very low energy consumption, energy carriers' consumption has not led to GDP while in the medium and long term, the feedback hypothesis is proven

In the new century, consumer concerns about environmental accountability, which are also aligned with environmental laws, have pushed a growing number of companies to design and create environmentally friendly programs. Accordingly, this study examines how to implement a green marketing mix to sell a product and stay in the market. Based on this, a sample of 90 investment marketing specialists in the field of green marketing in the field of energy was randomly selected and examined according to the volume of each category. The conceptual model of the research was designed based on the combined theoretical studies of green marketing and consumer intention and based on it, questionnaires were designed and the desired data were collected. The results show that in order to research the objectives of the research, the following items should be considered in such a way that they can compete with similar types: the use of recyclable materials to produce the product to reduce environmental damage, the introduction and presentation of environmentally friendly energy in exhibitions, conferences and seminars, the use of update transportation system to distribute products in the market to do less harm to the environment, appropriate pricing of green products.

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

Given the importance of oil prices, proper prediction of the OPEC Reference Basket can have an essential role in the immunization of economies in these countries against the effects of these fluctuations. This research is an effort to introduce an optimal model for modeling and predicting the fluctuations in OPEC crude oil prices. In this regard, we used data of daily oil prices between 2/1/1986 and 13/2/2017. According to this, the existence of long-term memory in the average equations and variance of crude oil prices were assessed and modeled and the result of the ARFIMA, confirms the existence of long-term memory in both the average equation and series variance. However, tests confirm non-linear and exponential behavior in crude oil prices. For this reason, results are specifically based on the information criteria and also MAPE and indicate the selection of a mixed model of partial augmented average movement and the model of conditional exponential Heteroscedasticity EGARCH (1,1) AFIRMA (4,0.09,3) as the best model for modeling and predicting the OPEC crude oil fluctuations in prices and lack of attention to exponential non-linear variance in the long term memory of crude oil prices can cause an error in the calculation of analysts and especially economic decision maker and deviation optimal policies.

Due to the problems and limitations of using fossil energy sources, the use of biofuels in order to achieve the goals of sustainable development, reducing greenhouse gas emissions, regional development, and security of energy supply, has received more attention. Therefore, considering the importance of the issue, in the present study, while determining the effective factors on the tendency of farmers to accept the supply of crop residues of wheat and barley products for bioenergy production, the economic value of residues of selected products in biogas and bioethanol energy production is estimated. Accordingly, using a survey approach and by completing a questionnaire by farmers in Boroujerd in 1399, data collection and research hypotheses were tested using the logit regression model. The results of the study indicate that the variables of collection cost (with a final effect of -0.097 and elasticity of -7.39%), non-agricultural income (with a final effect of -0.028 and elasticity of -6.37%), and use from residues (with a final effect of -0.014 and a tensile strength of -11.6%) have a negative effect on the supply of agricultural residues for bioenergy production. Meanwhile, education (with a final effect of 0.09 and elasticity of 4.4%) and farmer experience (with a final effect of 0.022 and elasticity of 17.32%) have a positive effect on the supply of agricultural residues for bioenergy production. According to the results of traction, farmers' experience and farmers' use of agricultural residues have the greatest effect on the supply of agricultural residues in bioenergy production. The results also show that the annual production potential of bioethanol from wheat and barley residues is equal to 63.96 million liters. So that if the same residues are used in biogas production, the annual biogas production potential is equal to 88.98 million cubic meters. Accordingly, the economic value of bioethanol and biogas energy production from wheat and barley residues in the study area has been calculated equal to 15349 and 430 billion rials, respectively. Therefore, based on the results, by planning for the principled management of agricultural residues and investing in the use of biomass as clean sources for bioenergy production, effective measures can be taken to reduce the dependence of the country's economy on fossil energy and provide the energy needs of people in remote areas.

The aim of this study was to estimate the nonlinear effect of oil, gas, electricity, and coal energy consumption on carbon dioxide emissions in ten energy-intensive countries (Iran, South Korea, Japan, Germany-Russia-USA-India-Canada-Brazil and China) in the world. Statistics and information used to estimate the nonlinear autoregressive panel model with distributed intervals (PANEL NARDL) have been extracted from the database of the World Bank and the World Energy Organization for the period 1985-2019. The results show that increased consumption of gas, electricity, coal, and oil leads to increased carbon dioxide emissions, while a decrease in their consumption reduces carbon dioxide emissions in the long run. Also, the nonlinear relationship between the per capita of consumption of these four types of energy and the emission of carbon dioxide in high-consumption countries was confirmed by the parent test in the long run. Therefore, reducing the use of fossil fuels and shifting the focus to clean and renewable energy consumption is proposed for the five selected countries, especially Iran, and economic policymakers should prioritize environmental protection by enacting applicable laws. In this way, the creation and development of intelligent infrastructure for the carbon economy and industry are essential.

It is necessary to develop the photovoltaic industry due to the criticality of reducing economic dependence on fossil fuels and mitigating air pollution. Therefore, the present study aims to propose a financing model for this industry in Iran. This is an applied-developmental study, in terms of purpose. It is developmental because it provides a framework for financing the industry. On the other hand, it is of an applied nature, as its results find direct application in developing this industry. The modeling draws on a mixed-method approach combining the qualitative methodology of grounded theory and the quantitative method of artificial neural networks. The study's population comprises the financial, economic, and technical experts of the photovoltaic industry. Semi-structured interviews took place with 25 experts chosen through targeted sampling, combining maximum variation with snowball sampling methods. The findings indicate that the investment funds (one of the primary strategies of community financing), bank loans (one of the private financing strategies), power purchase agreements (a government incentive), public funding by modifying the fossil power tariffs, along with guarantees and insurances are among the strategic priorities for financing this industry. In sum, the financing model of the photovoltaic industry demonstrates that based on the current context in Iran, it is possible to create a profitability perspective and a supportive atmosphere for the photovoltaic industry by adopting diverse strategies.

The global interest in using natural gas has increased considerably, and some factors such as low cost, safety, availability, environmental advantages, technological development, and its applications especially for gas turbines, have caused petroleum fuels replaced by natural gas. Many technologic solutions proposed in the market are reviewing the challenges and opportunities of using natural gas for the sake of knowing the relevant productive ways. As one of these solutions, in this article, a model for selecting the best fuel in the natural gas value chain through four options has been introduced, Compressed Natural Gas, Liquefied Natural Gas, Dimethyl Ether, and Gas-To-Liquids. Based on a comprehensive study, the criteria affecting the decision are determined. Then, using a Delphi method and expert judgments, 20 final criteria were selected. After that, the criteria were ranked; using a group consensus among the experts with Kendall's coefficient of concordance equal to 0.808. To transform the ranks into the weights, the paper uses the Rank Order Centroid (ROC) method. Finally, the best fuel is determined, with the use of the Combined Compromise Solution (COCOSO) method. The results have shown that at first LNG and then CNG is the best options for Iran. The realities of the world are verifying the accuracy of the model.

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.

In economic theories, Fiscal decentralization represents the shifting of decision-making power about the composition of tax revenues and non-tax revenues or expenditures are from the government to local units to provincial government officials, which leads to increased efficiency in resource allocation. And, since the pioneering study of Oates (1972), fiscal decentralization and its effects have garnered significant attention among economists. In the past years, global warming, carbon emissions, climate change due to increased energy consumption have brought the issues of fiscal federalism versus provincial institutions to the agenda of policymakers and energy research institutes. Because fiscal federalism can play a crucial role in reducing non-renewable energy consumption, promoting renewable energy, and reducing carbon emissions. Hence, energy economists have endeavored to shed on the association between fiscal decentralization and energy consumption and carbon emissions. In this way, this paper examines the effect of fiscal decentralization, in the form of shifting revenues and tax incomes responsibilities from the government to provincial institutions, as well as raising of the urbanization, GDP, and energy price on energy consumption for 31 Iran provinces from 2006 to 2020. To this end, this paper employs Quantile Regression with Non-additive Fixed Effects to analyze the impact of fiscal decentralization on energy consumption. The results of this study show that fiscal decentralization has a non-linear relationship with energy consumption. In addition, the rising urbanization and GDP lead to high demand for energy consumption. Moreover, the rising energy price leads to low energy consumption.

According to apposite and ambiguous opinions about the effects of foreign direct investment and innovation on environmental performance in developing countries, in this research despite the environmental Kuznets curve (EKC) hypothesis, pollution haven hypothesis (PHH), and rebound effects hypothesis (REH) in D8 countries (Iran, Turkey, Malaysia, Indonesia, Egypt, Pakistan, Bangladesh, and Nigeria) were studied. For this purpose, the required data was gathered from World Bank during the years 2000-2018. Also, the fully modified ordinary least squares (FMLOS) model and STATA software were applied for analyzing data. Results of variables description indicated that during the studied period, Iran has the lowest average amount of FDI to GDP, the lowest average amount of per capita GDP growth, the highest average of the proportion of fossil energies to total energy consumption, and the highest average of the proportion of per capita CO2 emission. In addition, the results of the specification of the econometrics model showed that there is a U inverse relationship between GDP and CO2 in D8 countries. Therefore, the EKC hypothesis is approved for studied countries. Also, foreign direct investment has a positive significant effect (in 10%) on CO2 emission. Hence, the PHH hypothesis is approved for studied countries. Finally, innovation has a negative significant effect (in 5%) on CO2 emission. Hence, the REH hypothesis didn’t approve for studied countries.

Energy consumption in the world is increasing for economic growth, and as a result of the emission of greenhouse gases, especially carbon dioxide, which has destructive environmental effects, the consumption of fossil fuels has an increasing trend. Present study tries to find the effect of renewable and non-renewable energy consumption on air pollution with respect to the moderating role of economic growth, utilizing the data of time series from 1990 to 2017 in Iran and with the generalized method of moments and in terms of some control variables such as energy efficiency coefficient and urbanization, the hypotheses were tested. Findings indicate that, the effect of renewable energy consumption in reducing carbon dioxide emissions (negative coefficient at a significant level of 10%) and the effect of non-renewable energy consumption in increasing carbon dioxide emissions (positive coefficient at a significant level of 5%). Also, the role of economic growth as a moderating variable on the relationship between renewable energy consumption and carbon dioxide emissions is positive and on the relationship between non-renewable energy consumption and carbon dioxide emissions is negative and significant. Developing investment and increasing the share of the renewable energy sector in the country along with improving energy efficiency and technology level can be effective in reducing air pollution.

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..

The main purpose of this study is to identify and prioritize different gasoline pricing policies in Iran based on sustainable development indicators using the Delphi method and Analytical Hierarchy Process (AHP). To this end, first, various types of gasoline pricing options along with evaluation indicators of these options were extracted separately in economic, social, and environmental terms by the Delphi method based on reviewing studies and interviews with specialists and experts. In this section, four pricing options for gasoline pricing were extracted entitled (i) “Double pricing of gasoline or continuation of the current trend; (ii) “Single rate gasoline price and cash payment of subsidies to cars; (iii) “Proportional pricing for gasoline consumption; (iv) “Single price of gasoline and allocation of quotas to people instead of cars. Then, these options were evaluated and prioritized in terms of economic, social, and environmental indicators in the framework of the AHP method. The results show that pricing commensurate with gasoline consumption or consumption tax (third option) is the best pricing option among the mentioned options. In this option, environmental and economic indicators are of great importance, and the price of gasoline between the quota price and FOB is determined in proportion to the consumption of individuals and sudden price changes do not occur for all consumers and the price of gasoline is completely dependent on the consumption behavior of individuals. Thus high consumption is always faced with higher taxes and allows for a fairer distribution of subsidies and reduced smuggling incentives for this fuel.

Due to the importance of economic relations and environmental potential issues, the relationship between economic growth and environmental degradation is a very important issue. Therefore, understanding the relationship between GDP growth, consumption and extraction of fossil fuels, use of renewable energy, and emissions in the Iranian economy are very important for sustainable development. In this study, we try to investigate how emissions (as the main cause of pollution) are affected by per capita income growth, innovation, renewable energy consumption, and extraction from non-renewable energy resources in a model with four equations (for Iran in period 1979 to 2019). By reviewing the wide range of studies, the framework developed in this paper has not been investigated in domestic or international studies. On the other hand, in this research, for estimating nonlinear simultaneous equations, the multi-objective optimization method and its application for estimating simultaneous equations in econometrics have been developed. (This method can be a way to estimate nonlinear simultaneous equations in future studies). The results showed innovation activities have not been able to have a significant effect on reducing pollution emissions for the Iranian economy. Also, we found out the consumption of renewable energy has not had a significant effect on reducing pollution emissions. Also, the existence of the Kuznets environmental hypothesis was confirmed and Iran is in the upward part of this curve.

Half a century after the oil crisis in the 1970s, there is still not any agreement among economists when it comes to the type and existence of any relationship between energy consumption and economic growth. In this regard, many studies have been conducted, and many methods have also been adopted to find this relationship, most of which are now proved to be inappropriate and inefficient. Having utilized a new causality approach proposed by Konya (2006), this study investigated the relationship between three energy carriers, natural gas, electricity, oil products, as well as considering the value-added of sixteen main industrial sub-sectors in the period 1995-2017, via the bootstrap panel approach. Comparison to the traditional methods, one of Konya's merits is paying attention to the two categories of heterogeneity of coefficients and cross-sectional correlation, making the estimation of parameters more efficient. The results show that in five sub-sectors of the industry, including “rubber and plastic”, “other non-metallic mineral products”, “manufacture of machines and unclassified equipment”, “machinery generator, electric transmission, and unclassified electrical appliances”, “manufacture of motor vehicles, trailers and semi-trailers” there is a one-way causal relationship from value-added to natural gas consumption. On the other hand, in an industrial sub-sector of “manufacture of chemical products”, this relationship is two-way. Also, there is a lack of causal relationship between electricity consumption and value-added in sixteen industrial sub-sectors. Moreover, a one-way relationship from value-added to the consumption of oil products can be seen only in the industrial sub-sector of “manufacture of other transport equipment”. According to the results of this study, it seems that energy consumption is not dominant in the economic growth of the Iranian economy, and the government can adopt necessary policies regarding energy price liberalization and demand management without worrying about its dire consequences.

Considering the critical role of energy consumption and productivity in economic growth, the central purpose of this study is to investigate the effect of some key macroeconomic variables and energy consumption on the total factor productivity of the agriculture sector in Iran. First, the Solo residual parametric method is employed to estimate the total factor productivity index. Subsequently, the quantile regression method is applied to time series data for the period 1967-2016 in order to investigate the impact of mentioned variables on the total factor productivity. The main results showed that energy consumption and lagged inflation rate have a negative and significant impact on the total factor productivity in agriculture in the 0.25 and 0.5 quantiles. On the contrary, market exchange rate, foreign investment, and lagged TFP exhibit a positive and significant impact on the total factor productivity of the agricultural sector.
