This paper analyzes the existence of an asymmetric causality relationship between the consumption of hydrocarbon products in four sectors: residential-commercial, manufacturing, agricultural, and transportation, and the economic growth of Iran during the years 1981-2017. To achieve this goal, the effect of positive and negative shocks of the mentioned variables is investigated using the asymmetric causality approach of Hatemi-J (2012). Research results suggest a two-way causal relationship between the positive shocks of economic growth and the consumption of carriers of hydrocarbons in all four residential-commercial, manufacturing, agricultural and transportation sectors. There is a two-way causal relationship between negative economic growth shocks and hydrocarbon carriers’ consumption in agriculture and transportation, and a one-way causal relationship between hydrocarbon energy carriers’ consumption and economic growth in the residential-commercial and industrial sectors. There is no causal relationship between non-directional shocks of hydrocarbon consumption and economic growth.

Foreign investment contracts are one of the major ways to absorb the technology in the oil and gas industry. Studies show that governments and investing companies prefer to gain more profit, control economic resources and political influence by investing financially and technically in developing countries unless buying foreign technology and intellectual property rights directly. On the other hand, for developing countries, the sum of foreign capital and technology within a contract is a great opportunity for advancement, provided that the choice of technology transfer is made with due regard to the country's needs, requirements and economic future. In this article, after examining the relationship between investment and technology transfer and its various methods in the oil and gas industry, we will analyze the constraints and barriers of technology transfer through foreign investment in developing countries (including Iranian law) and provide a solution. Keywords: Foreign Investment, Technology Transfer, Oil & Gas Industry, Mutual Trade, Intellectual Property Rights.

The main purpose of this research is to explain why and how the stock liquidity affects the default risk of petrochemical and petroleum products companies listed in Tehran Stock Exchange. The study used experimental data and parametric tests in order to estimate the relationship between stock liquidity and default risk through information efficiency and corporate governance roles of stock liquidity. The present research is applied in terms of purpose and is a descriptive-correlative study. All data required regarding the stock liquidity, price, trading volume and days, stockholder ownerships, etc., were extracted from Rahavard Novin database software. To investigate the relationship between variables, the multivariate regression analysis model using OLS method was applied in Eviews platform. The empirical findings showed that there is a significantly negative relationship between stock liquidity and default risk of petrochemical and petroleum product companies listed in TSE and also stock liquidity can affect the default risk through reducing the information asymmetry in the stock pricing process and strengthen the corporate governance. These results could provide visible signals based on the realities of the market in order to improve models to assess and predict the risk of default and lead managers and decision makers of suppliers, customers, partners and stakeholders, to conclude more flexible contracts with petrochemical and petroleum products companies and ultimately better mitigate business risks.

The purpose of this study is to evaluate the financial performance of provincial gas distribution companies as affiliates for National Iranian Gas Company. To this end, we identified financial performance indicators in accordance with the requirements of NIGC through a review of theoretical foundations and interviews with a number of financial and planning experts and then prioritized using the Analytical Hierarchy Process method. These indicators lied in four groups of liquidity, capital structure, profitability and activity criteria, respectively. Then, the weighted indicators were analyzed using TOPSIS technique in Expert-Choice software and the final ranking of the companies was provided. The results showed that based on the identified criteria, provincial gas companies of Hormozgan, Yazd, Markazi, and Kermanshah had a favorable financial performance and Ilam, Mazandaran, Chaharmahal and Bakhtiari and Zanjan provincial gas companies had a weak financial performance with respect to other companies in three years under review and some suggestions have been made in this regard.

This study aimed to evaluate the effects of environmental policies including price and non-price policies on natural gas demand in Iranian industrial sector. For this purpose, considering the dynamic nature of our panel data, we adopted Generalized Method of Moments (GMM) method to estimate natural gas consumption for 22 Iranian industries from 2005 to 2015. The results illustrated that the annual average of natural gas consumption has been rising, reaching five times higher than the consumption of other fossil fuels. Among the industries, other non-metallic minerals industry with 8 percent of the total production and more than 25 percent natural gas consumption have been regarded as the most natural gas consumer industry. The results of our GMM model showed that non-price environmental policies are more effective than the price policies on natural gas consumption. Overall, in non-price policies, energy intensity seems more important comparing to CO2 emission reduction. We recommend that governmental energy policies should focus more on energy intensity improvement in Iranian industries through technological enhancement and fuel energy saving regulations.

The present paper is meant to answer the question: How fluctuation in economic growth rate increased the risk of instability in Iran in the Post-JCPOA? In response and based on reliable data and taking a political economy approach, it is hypothesized that the high fluctuations in the economic growth rate associated with JCPOA has led to the political instability through deepening and intensification of expectations gap. To do so and using a comparative method, a number of factors associated with calculating modes of added value (sub-sectors including agriculture, oil, industry and mining, and ) as well as international indicators affecting the economic growth are analyzed in the two time spans of pre and post JCPOA. For further validity, reference is made to the results of some polls conducted by some credible institutes. The findings show that the sudden rise and fall of the economic growth rate due to oil revenues after the agreement turned the hope created in the context of the expected gap formed by the promises of the agreement into disappointment; and paved the way for street unrests
