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

One of the requirements for the formation of stability in regions and sub-regions is the creation of regional security complexes. The necessity of creation these regional security complexes is the existence of security orders which are outcomes of regional actors’ agreements to control internal crisis and challenges and to manage the level of external interventions in regional affairs. Due to its geopolitical, geo-strategic and geo-economic importance, especially in the oil field, the West Asian region has a great impact on the international security of the oil market, and the formation of an endogenous regional security complex can provide the necessary basis for oil security. The strengthening and expansion of the Axis of Resistance strategy under Islamic Republic of Iran leadership in formation a regional security complex could ensure oil security, as much as possible. This article studies the central impact of the Axis of Resistance strategies, especially the Islamic Republic of Iran in ensuring oil security through the formation of regional security complex. Countering unilateralism in oil market management, countering US-managed chaos to gain new customers in the oil market, and countering oil conversion as a financial source for international terrorism are some of the strategies of the Axis of Resistance and the Islamic Republic of Iran in this regard.  

The present research seeks to assess the relationship between the Individual value system and decision-making styles. The statistical population (190 people) consists of Pars Special Economic Energy Zone (PSEEZ) Organization managers who were assessed using the Census Method. The Myers and Myers cognitive demographic and value systems questionnaire and Scott and Bruce’s decision-making questionnaire were used with a response rate of 90%.. Data was analyzed with the SPSS and Smart Planning softwares. It was found that the dominant Individual value system is success-oriented, followed respectively by system-oriented, realistic, tribal, community-oriented, and autocentric.Also, the dominant decision-making style in the statistical population is rational, followed by intuitive, dependent, avoidant, and spontaneous decision-making styles respectively. It was also concluded that success-oriented and tribal value systems had the most significant relationship with decision-making styles and the community-oriented value system the least. Only the individual variables of race (ethnicity) and field of study had a significant relationship with the Individual value system. The other personal and organizational variables had no significant relationship with the Individual value system. Creating motivation and a sense of employee participation in the future of the organization is proposed as the most important way of improving the value system of the statistical population so that the tendency to make spontaneous decisions can lean more towards making rational decisions to the same extent. Investigating the relationship between decision-making styles is another effective topic in improving these in an organization and is thus recommended to other researchers in the field.

Environmental tax reform can be used in a fundamental transformation towards a green economy. Green tax may reduce the energy consumption and pollution emissions, as well as other economic benefits. This study mainly focused on the effects of green taxes on labor demand in Iranian industry sector during 1980 – 2015. Regarding the double dividend hypothesis, green taxes may improve the employment by substitution between labor and energy. Using CES production function, the elasticity of substitution between labor and energy is estimated 0.48 percent for industry sector. Then, the effect of green taxes on labor demand is investigated subject to government’s fixed budget constraint and labor demand function. The results show that green tax will have positive effects on employment in the industry. During the transfer of the labor tax system to the green tax system, the environment and employment may improve, without additional cost to the government and producer.

By intensifying sanctions against Islamic Republic of Iran, identification and development of mechanisms to sell crude oil has gained attention among most experts and oil industry activists. Limitations for financial transactions and settlements are one of the fundamental challenges in international oil transactions; thus, various solutions are proposed to solve the limitation. Using capability of virtual currencies is one of the proposed suggestions for petroleum transaction under sanctions but there is a research gap in finding whether and which one of these currencies are able to be used in petroleum transactions in present condition. In this study, performed by analysis and quantitative approach, indices are introduced for choosing a valid currency for international transactions, and subsequently are confirmed by experts. The indices are ranked by the experts through TOPSIS method and are studied on the most suitable virtual currencies to find the best suit for petroleum transactions. The results reveal that Bitcoin, Ethereum and Tether are respectively the best, second and third choice for this end. It is noteworthy that some experts might believe the virtual currency market size may not meet the high volume of crude oil transactions, making it unsuitable. Although current study has shown that there would be no problem in covering the whole petroleum market for Iran’s crude oil by virtual currencies platform, if the concerns remain, virtual currency platform could be used for selling Iran’s crude oil temporarily and partially through various channels.

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.

South Pars gas field is the largest gas field in the world and is shared between Iran and Qatar.One of the most important projects in this field is the development of Phases 17 and 18. This mega project is one of the most important projects implemented in the South Pars gas field.This paper examines the impact of domestic inflation on the costs of implementing these phases over a period of ten years(2003-2013) .The main purpose of this study is to calculate and compare the costs of implementing this project under non-inflationary conditions.For this purpose, the main and standard activities of this phases is selected and its costs calculated and then neutralize inflation indicators for the desired time period to be compared between inflation and non-inflationary states.Wilcoxon test used to compare two dependent groups.Based on statistical analysis,assuming the absence of other factors,the expenditures of selected activities in phases 17and 18 of South Pars in the inflationary state were significantly higher than the non-inflationary state Keywords:South Pars Gas Field, Domestic Inflation
