The purpose of this study has been to consider the effects of non-price factors along with price factors on the demand of Iranian export from 1988 to 2017.In this research, a single error correction model is used to evaluate the short-term dynamics and long-term effects simultaneously. Moreover, in this study compare to previous researches, a more flexible approach has been included in the export function which is based on the structural time series' patterns which are the trends that express the effects of non-pricing factors. Then, the OXmetric software and the Kalman filter is utilized to estimate the amount of trend in each year, and the effect of each factor on the trend component is evaluated by the Ordinary Least Square Method. The results indicate that the price elasticity of the export is low. Also, the impact of non-pricing factors such as globalization, total productivity of production factors, innovation, electronic commerce and foreign direct investment on non-oil exports were assessed. The results have shown the significant effect of all factors and the negative impact of economic freedom, openness and foreign direct investment on the implicit process export.

Greenhouse gas emission abatement is an important issue at the center of attention worldwide with the aim of achieving sustainable economic growth. One of the policies put forward in this area is to subsidize investment in research and development and to levy tax on fossil fuels in order to make appropriate technical changes to reduce greenhouse gas emissions. The present paper determines the subsidy rate for investment in research and development to double it with using a computable general equilibrium model. It considers in the first scenarios subsidy payment for investment and in the second scenarios subsidy payment along with, the taxation of fossil fuel consumption. It then examines the economic, welfare and environmental impacts of these policies. The results of modeling and calibration show that in the first scenario, the subsidy rate for investment in research and development is 9.4% and in the second scenario it is 9. 1%. Meanwhile, the tax rate for fossil fuels in the second scenario is 2.5%. The results indicate a reduction in welfare in both scenarios, regardless of the social gains of reducing emissions. The results also show that both the energy tax policy, and research and development subsidy policy is able to reduce energy consumption and air pollution.
