Utilization management of Persian Gulf oil and gas reserves is important, because of the importance of this area owing to the fact that it comprised 60% of the proven oil reserves and 40% of the proven gas reserves of the world and it determines the world's oil and gas strategies. By using game theory, this paper seeks to achieve the best strategy that Iran could use in confronting other partners of common fields. Moreover, it seems to find the best approach for Iran and other countries in cooperation and non-cooperation conditions in extraction. The results showed that the higher the number of countries for a common resource, the less the attempt of each country would be; however, the more the total attempt of countries will be, which means more waste of attempt. Overall, partner countries in a resource are recommended to take actions to extract common resource via agreement and mutual cooperation; so that they could extract the same amount of common resources exercising less effort.

Industrial subsidy is one of the important tools in support of the national production that plays a crucial role in the realization of a resilient economy. Regarding limited financial resources, it is important to determine how these subsidies can be distributed efficiently. Accordingly, the purpose of this study is to provide a model for allocating industrial subsidy among 22 manufacturing industries at the level of 2-digit ISIC codes using the ZSG-DEA model based on the merging of the concepts of game theory with the DEA, and also four effective criteria in allocating public resources namely, industrial added value, the number of industrial employees, the amount of direct export and the amount of industrial taxes and duties. The results of the study show that the food and beverage industry should receive the highest proportion of the optimum subsidy, whereas industries related to manufacturing office machines, accounting and computing machinery, radio, television, communication devices, wearing apparel, tanning and polishing leather and leather goods, fur, and manufacturing tobacco products should receive the lowest proportion of industrial subsidies.

In this study, the social welfare impacts of the interaction of Iranian rice import policies and Thai export policies are analyzed using a game theoretic approach in conjunction with econometric supply and demand models. The joint impacts of increasing the world price of rice, resulting from the export policies in Thailand along with changes in tariff rates in Iran, on social welfare are analyzed in the two countries. Because Iran is a small country in terms of the volume of world rice trade its policies do not influence Thai social welfare. Results of this study show that in order to maximize its own social welfare, the government should impose a modest tariff rate of approximately 3%. This is much less than the actual tariff rate applied in recent years, e.g. 19% in 2007.
