This is vital in CGE modeling where it is conventional to take elasticities from other studies. In the present study, the robustness of model results with respect to the functional form is checked. In one scenario, the production function is represented by CES function (a globally regular functional form) and in the other by Translog function (a flexible functional form). The model results are found to be sensitive to the chosen functional form, especially in the oil sector. Thus, only the functional forms that historical data approve their validity for Iran should be employed in CGE models of Iran. One of the main sources of information employed in general equilibrium modeling is the functional structure.
