the effect of gas pricing on the export of gas from Iran and Qatar: integration of dynamic Computable general equilibrium (CGE) approach and game theory

Considering the existence of oil and gas fields between iran and qatar and the impact on the market through a higher export share, the purpose of this research is to investigate the optimal gas price on the amount of gas exports of these countries. therefore, in the present study the dcge model and the 2014 social accounting matrix were used to investigate the impact of gas price shocks on the gas exports of these two countries. as iran and qatar are known as main competitors in the natural gas sector of world energy market, it is necessary to specify a win-win pricing strategy for both countries. taking this into account, in the present study a model that incorporates both the dynamic computable general equilibrium and game theory is used for investigation purposes in 2022-2024. at first, in the dynamic computable general equilibrium model, price increase scenarios of 0.5, 0.7, and 1 percent were performed on iran and qatar's gas exports, and then using these results, the pay-off matrix was obtained for these countries.the results indicate that, 0.5% price increase would be the best strategy from among the wide range of gas price scenarios presented for 2022-2024, because a 0.5% increase in gas prices in general would further increase the exports of iran and qatar as two competitors. thus, based on the equilibrium forms, stepwise price rise over a specific time interval can help these two countries maximize their interests.
