Investigating the Effect of International Agreements on the Quality of the Environment from the Foreign Direct Investment Channel with the CGE Model Approach: Case of JCPOA

The absorption of FDI is possible only in the light of the widespread international relations and the stability of the domestic political and economic situation. In this regard, it is expected that the conclusion of international agreements will pave the way for FDI and, subsequently, technological overflows eventually lead to economic growth. Theories related to environmental economics show that the above process can be accompanied by a reduction in the quality of the environment. In this study, the environmental and economic impacts of FDI and the improvement of TFP in the six scenarios were evaluated in the framework of the general equilibrium model. The results show that the entry of FDI in a situation where there is little technological overflow and poor productivity, the economic growth is accompanied by an increase in carbon emissions. Therefore, technology overflows in the FDI process have a substantial effect on improving environmental quality. JEL Classification: C68, D58, Q58
