In this paper, firstly, the impact of government expenditure on economic growth in Iran (1980-2016) and MENA countries (2000-2016) is investigated using VAR and PVAR models. Further, the government expenditure multiplier are calculated and compared comparatively using the impulse response functions of each model. At the end, the effect of each factor is investigated determining the government expenditure multiplier in separate models for Iran and selected countries of the MENA for a better analysis and a closer investigation of the subject. According to the literature, results indicate that: Firstly, the shock of government expenditure in MENA selected countries and Iran, together, led to a relatively strong increase in economic growth. Secondly, in developing countries such as the countries of MENA region, especially in Iran, government- expenditure multipliers were smaller than one and close to zero. The government expenditure multiplier in MENA selected countries is more than Iran in short-term, but in the long run, the government expenditure mulitiplier, in Iran is larger than MENA selected countries. Thirdly, trade openness, public debt, and savings rate both in MENA and in Iran reduce the government expenditure multiplier, but unemployment and financial development increase the multiplier. Public debt has the most impact on the Iranian government expenditure multiplier and trade openness has the most impact in MENA expenditure multiplier.

Planning and policy making in the field of economic growth as one of the major macroeconomic goals requires special attention to the energy sector, the environment and its relation to production. Hence, in this paper, the effects of energy consumption shocks on carbon dioxide emissions and economic growth in selected countries of the MENA have been studied using the PVAR approach as well as Iran using the VAR method, and the results indicate that the energy shocks would initially lead to a relatively high increase and then a decrease in per capita GDP in the selected countries. The energy shock also initially increased carbon dioxide emissions and subsequently reduced pollution in subsequent periods and will move to the balance in long-term; also, in the Iranian economy, a shock to energy consumption first begans to sharply increase in economic growth after four periods, and eventually returns to a long-term equilibrium. Eventually, with a shock in total energy consumption, carbon dioxide emissions are mildly increased and then begin to decrease from the third period. Total energy consumption, foreign direct investment, labor force, and capital stock have a direct and significant relationship with economic growth, but carbon dioxide emissions have a significant negative relationship in Iran's economy.
