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.

In recent years, privatization in the downstream industries of oil and gas , has been one of the most important measures taken to change and improve the business environment and remove barriers of production, as well as to implement of the general policies of Article 44 of the Constitution. This study intends to check out eleven variables related to the performance of six companies: Isfahan Oil Refinery, Bandar Abbas Oil Refinery, Tehran Oil Refinery, Lavan Oil Refinery, Shiraz Oil Refinery and Tabriz Oil Refinery by DID (fuzzy) method and compare it with control groups in order to Assess the privatization status of these companies. The results of this study show that two variables out of the eleven variables -, the ratio of general administrative and sales costs to revenues and the number of staff before and after the transfer, were significant for the control group. In other words, the employment situation and general administrative and sales costs in the companies under review were more unsatisfactory than the control group and in this regard, they had poor performance. This shows that in practice, the transfer of these companies has not affected the employment situation, positively.
