The purpose of this paper is to evaluate the role of ICT due to ecological footprint from the perspective of individual effect and the trend of the 113 countries' reserves and land production in selected developing countries using the data panel method in the period 1992-2018. The results showed that increasing the mobile penetration rate increased greenhouse gas and carbon dioxide emissions and increased the ecological footprint effect. However, increasing the Internet penetration rate has reduced carbon dioxide emissions, increased greenhouse gases, and increased ecological footprint. Therefore, ICT use in these countries has not yet been effective in improving the environment. In the short term, there is a positive relationship between economic growth and environmental degradation in these countries, and economic growth worsens the quality of the environment. And in the long term, there is evidence of the Kuznets hypothesis being correct. Dynamic analysis showed that the use of ICT has been effective in improving the environment and this effect lasts for at least a decade. Technology shocks have an immediate effect on improving some environmental indicators and the range of effects on some indicators appears in the long term. In these countries, the production of ICT has no relative advantage, but they can benefit from the economic and environmental benefits of ICT.

The growth and survival of a company are based on making appropriate and principled investment decisions. This is while a company always continues to operate in an unpredictable environment and under the influence of various shocks. In this regard, this issue has created a two-way relationship between investment and uncertainty. Therefore, this study examines the relationship between investment and uncertainty in the Iranian oil industry during the period 2010 to 2019 for 32 listed companies active in the oil industry. In this regard, using the vector auto-regression approach with generalized auto-regression conditional variance heterogeneity moment, first, the structural shocks of the oil market are extracted, and then using the generalized moments approach of the Tobin q investment model is estimated. Findings show that the shock caused by global demand (εpw), and the shock caused by the global stock market (εsp) have a negative and significant effect on the ratio of gross investment to corporate capital stock. The ratio of gross investment to the company's capital stock has a negative effect on its amount with a one-year delay, which is also statistically significant. Oil supply shock (εopw) and oil price shock (εrp) have a positive and significant effect on the ratio of gross investment to the company's capital stock. The ratio of market value to the replacement value of company assets has a positive and significant effect on the ratio of gross investment to capital stock. In this regard, due to the effectiveness of oil companies’ investments in global variables such as global oil price fluctuations and supply and demand shocks, investors' stock insurance against sudden fluctuations and shocks is recommended.

Energy-intensive industries in Iran are responsible for a significant share of energy consumption, especially oil products. Therefore, there is a major focus on promoting energy efficiency in such industries. Energy efficiency improvement results in rebound and backfire effects. In this paper we estimate the effects of fuel oil efficiency improvement in energy intensive industries based on intertemporal general equilibrium model. Simulation for long run period is done for two scenarios, including 3.1% efficiency improvement in energy intensive industries and all sectors of economy. Results show that the rebound effects in chemical industry, food and beverage, basic metal, paper, Rubber and plastic, non- metallic minerals, and wood industries leads to rebound effects in the first scenario. In the long-run, backfire effects are seen in the second scenario in which efficiency improvements for all sectors is considered. In addition, efficiency improvement will result in production cost decrease. Chemical and non- metallic mineral industries experiencing the most decreases of production cost around 1.1% and 0.7%, respectively.

The continuous growth of electricity consumption in Iran, due to the low and unreasonable prices, has created immense pressure on the national network of supplying electricity to meet the ever-increasing demand. The realistic and economically justifiable pricing of electricity has, therefore, become an urgent issue for managing supply and demand. The residential electricity consumption in the country is one of the main sources of such demand increase. The present study focuses on the impacts of government subsidies on electricity demand and consumption for the urban and rural households in Iran. Data used for this study include price index, urban and rural household expenditures, provided by the Iranian Center for Statistics, Central Bank of Iran during the period 1991-2012. The study utilizes Almost Ideal Demand System (AIDS) and Seemingly Unrelated Regression (SUR) estimation methods for data analyses. The results show that electricity is an essential good for both urban and rural households, and as such the demand and consumption levels for both urban and rural households in the country have very little (less than one) elasticity to prices. The conclusion is that the demand levels for residential electricity consumption are not meaningfully reduced by the price increase for customers created by elimination or reductions of governmental subsidies for electricity. Therefore, pricing policies alone would not be effective to reduce residential electricity consumption in the country, and there is a need for additional and supplemental policies.
