Environmental problems are one of the most challenging issues for the entire world and each country. In economic studies, environmental issues are analyzed as negative externalities. In this article, the negative externalities of electricity production on the output growth of different sectors and household’s welfare in Iran’s economy have been studied through price system using Computable General Equilibrium (CGE) model empirically. In this regard, Iran’s Social Accounting Matrix of 2011 and GAMS software by introducing five scenarios related to environmental effects of electricity production have been used. The results show that firstly, the internalization of electricity production externalities reduces the output of agriculture and industry sectors in all scenarios, while the output of services will increase. Secondly, internalization of electricity production externalities increases total economy’s output and declines the household’s welfare.

The main objective of this paper is to investigate the effects of technology transfer through the imports of intermediate goods by developing countries developed countries with the emphasis on Iran economy. For this purpose, we used multi-sectoral and multi–regional computable general equilibrium GTAP model (multi-sectoral and multi-regional CGE model). The paper examined the effect of a ten percent productivity shock in high-tech industries of industrial countries on economic sectors of Iran. The result shows that technology transfer embodied in Iran’s imports of intermediate goods leads to increase in outputs and decrease in prices. Factors such as absorptive capacity, structural similarity and effectiveness contributed to the spillover effects of technological improvements in Iran.

Despite the implementation of the first phase of fuel subsidy targeting in December 2010, there are still debates over the economic impact of this project in Iran. A CGE model is used to analyze the impact of fuel subsidy targeting in Iran in four different scenarios. The data are used in the framework of SAM for the year 2001. In all scenarios, indirect subsidies are removed completely and replared with direct subsidies to households, manufacturing and service sectors and government institutions. The findings of this paper show that the effect of fuel subsidy targeting on economic variables depends on the way this policy is implemented. We find that an increase in the income of low-income household results in an increase in the production level of basic goods. Moreover, the result shows that the mining industry, glass and other non-metallic minerals and other service sectors have comparative advantages. In all senatrios, the elimination of in direct subsidies results in stagflation. The inflation rate resulted from this policy is predicted to be between 16.1 to 21.1 percent. Furthermore, in all senariors, higher direct payments of subsidies to households are associated with higher growth and inflation rates and lower balance of payments.
