Energy is a basic need to continuity in economic development, supplying and providing welfare and comfort in human life. Due to the limitation and scarcity of resources and also considering the extended role and importance of energy in countries’ growth and economic development, determining the effective elements on energy demand is of a special importance. There have been many studies on energy demand in Iran. But this study has taken a different approach. This study deals with both the effect of energy market integration and the effect of economic growth on energy consumption in Iran’s economy during 1975 to 2014, using generalized method of moments. In this study, empirical results showed that integration of energy market and economic growth has significant positive effects on energy consumption. Also the price elasticity of energy demand in all models indicate the low elasticity in Iran’s economy during the mentioned years. Income elasticity has been estimated larger than one in final models.

The purpose of this paper is to determine the optimal time paths of economic variables such as production, inflation, money stock and government expenditures, and also sensitivity analysis of these paths. For this aim, a deterministic optimal control model is used. In this model, a quadratic objective functional, due to the constraint of dynamic macroeconomic equations system, will be minimized. In this method, the squared deviations of variables from their steady state values are weighted. Then, optimal paths of control and state variables are calculated by using Mathematica software. Optimization results indicate that if optimal policies are chosen, mentioned variables will considerably have less fluctuations. According to results of survey, analyzing the sensitivity of the model to policy weight emphasizes on inverse relationship between weight imposed by economic policy makers on the target variable, and standard deviation of values ofthe optimal paths for that variable. Also, this paper shows that mathematical economic models and techniques can be used in order to solve the problems of growth, production and inflation.
