The impact of technological advances on energy consumption is one of the topics that has been considered by many researchers and policymakers. Numerous researchers have tried to evaluate this relationship based on various technology indicators. The index of economic complexity is one of the new indicators that has been used in recent years to measure the level of knowledge and technology in the production structure. In this paper, the index of economic complexity along with energy prices and GDP have been used as determining factors of energy consumption in Iran during the period 1976 to 2018. Quantile regression results show that the coefficients of the variables are different in the deciles. The impact of economic complexity on energy consumption in all deciles has been positive, indicating the dominance of the rebound effect on energy consumption. Price elasticity is less than one in all deciles and less in the higher consumption deciles. In contrast, the income elasticity of energy demand was higher in the upper deciles

One of the important issues in the energy economy for policy making is the proper understanding of energy demand and the correct estimation of price and income elasticity. So far, extensive efforts have been made to estimate the elasticity of the energy demand in Iran, but the problem of the asymmetry of the demand dynamics and the change in the coefficients of the model during the boom and recession have been less widely considered. Therefore, in the present paper, considering the threshold error correction model, the dynamics of energy demand in Iran during the period of 1978-2014, is estimated with the consideration of the difference in the recession and economic boom. The results of this study indicate that there are two different regimes in energy demand dynamics in Iran. In recession, price and income elasticity of demand as well as the speed of adjustment is lower. While at the time of the boom, the flexibility of the demanders for reaction was greater, and so the price and income elasticity and speed of adjustment were higher. On this basis, although energy demand is inelastic at the time of the boom and in recession, and hence the implementation of pricing policies cannot be effective on demand, the effectiveness of these policies can be greater during the economic boom than the recession.

Energy intensity is one of the important and attractive indicators in energy economics. According to the abundance of energy resources in Iran, these resources are not used properly and therefore energy intensity is very high compared to other countries. Hence in this paper using a nonlinear regression method, we study the factors affecting energy intensity in Iran during the period 1979-2013. The results indicate that the existence of two regimes by considering relative price of energy as transition variable with the threshold about 1.58. The rate of urbanization and industrialization had positive effect and the level of technology and relative price of energy had negative effect on energy intensity in Iran. The effectiveness of relative price in the high price regime is intensified and the effectiveness of industrialization and technology is dropped. These results would suggest the important role of price regime on the effectiveness of energy intensity determinants in Iran and leads policy makers to prevent the decrease in the relative price of energy in the years following the implementation of targeted subsidies.

The relationship between energy consumption and economic growth is one of the important issues in energy economics. Total energy consumption and its utilization in various sectors can affect this relationship. Therfore it may imply that this relationship can considered in a nonlinear framework. In this paper we investigate the nonlinearity of the relationship between energy consumption and economic growth using a smooth transition regression model, where the non-productive part of energy use (i.e. final use) is assumed as the transition variable. The results indicates that there is a positive nonlinear relationship between energy consumption and economic growth in Iran. The effect of energy on economic growth is negative as the share of nonproductive sector’s energy use rises. Estimated output elasticity of energy in our sample (1967-2008) is between 0.14 and 0.88, and its mean is about 0.325.
