Energy supply and ensuring energy security for countries is a vital goal to achieve growth and sustainable development. Energy security provides a country's ability to meet current and future energy demand, resilience, and responsiveness to minimize systematic shocks to supply disruptions. This study uses five dimensions; Availability, Accessibility, Affordability, Acceptability, and Develop-ability, as well as by using entropy-weight and TOPSIS method, the composite index of Iran's energy security for the period 1980-2019 has been measured. The results show that Iran's energy security has decreased in the period under review. The highest level of energy security was 0.716 in 1982 and the lowest level was 0.272 in 2018. Also, the level of energy security was higher than 0.5 in the periods 1980 to 1987 and 1991 to 1993, and lower than 0.5 in the periods 1988 to 1990 and 1994 to 2019.

Energy is used as an input in the production, distribution and consumption of all goods and services. Therefore, it has a wide importance in the supply chain both from the perspective of the final product for consumers and from the perspective of production input for producers (Adom et al, 2019).This importance has caused the excessive use of energy to achieve higher economic growth and development, and has resulted in the destruction of the environment and the loss of natural resources. Indeed, although energy is necessary for economic growth and development, it can be said that it is necessary to worry about its lack and pay attention to environmental issues. Indeed, the limitation and depletion of energy resources has made the management of energy consumption one of the most important issues in the global economy (Harati et al, 2017). Therefore, studying the factors affecting efficiency in energy consumption and reducing energy intensity is one of the essential prerequisites for efficient management of energy consumption and reduction of environmental pollutants. Among various factors, the impact of financial development on energy intensity is one of the important issues that has been raised and shown its importance in the last few years. Therefore, this can have optimal policies in energy consumption and environmental efficiency.Therefore, the present research investigate the impact of financial development on energy intensity in Iran during the period of 1350-1397 under regime conditions.

To investigate the impact of financial development on energy intensity in Iran under regime conditions, vector auto regression model based on error correction (MS-VECM) has been used. The statistical data of financial development variables were collected from the WDI(2020) and energy consumption intensity from the energy balance sheet, as well as the statistics of economic growth variables, urbanization, industrialization and commercial openness from the WDI (2020).

According to the estimation model, the impact of financial development on energy intensity has been analyzed in three different regimes. According to the results, financial development in zero regimes has a negative and significant effect on energy intensity. In this regime, improving financial development has reduced energy intensity. In regime one, the impact of financial development on energy intensity is positive and significant, and the improvement of financial development environment has increased energy intensity. In regime two, financial development has a negative effect on energy intensity, but its effect coefficient is different compared to regime zero. Therefore, the results showed that energy intensity is affected by different regimes of financial development.

According to the results of the study, it can be said that financial development has an important and significant effect on energy consumption and intensity. When financial development is around its stable state and has little fluctuation, the impact of financial development on energy intensity is negative. It is important to pay attention to this point in Iran, where energy consumption and intensity are not in a good condition compared to other countries. Therefore, the results show that economic policy makers, in addition to paying attention to financial development, should also focus on the volatility and changeability of this variable and try to implement policies that do not cause large fluctuations in the financial markets. A momentary increase or decrease in credits, a sudden change in debts or a sudden change in bank assets can cause financial development to be in a single regime and have a positive effect on energy intensity. Therefore, the policy of paying attention to financial market variables and financial development indicators can improve energy intensity and increase energy efficiency.

In recent years, financial development and its effects on the environment have received increasing attention. Indeed, financial development directly affects economic growth and energy consumption, so that affects the release of environmental pollutants. On the other hand, developed financial markets and an efficient banking system improve productivity and reduce environmental pollutants. Therefore, the present paper investigates the impact of financial development on carbon dioxide emissions in Iran under regime conditions during the period 1971-2018.

In the present study, in order to investigate the effect of financial development on carbon dioxide emissions in Iran, the Markov-switching vector error correction method was used under regimes conditions.

The results showed that financial development under two regime conditions affects carbon dioxide emissions. This means that in the zero regime has a positive and significant effect on carbon dioxide emissions. While in regime one, financial development has a negative and significant impact on carbon dioxide emissions. Thus; Carbon dioxide emissions in Iran are affected by financial development regimes.

According to the results of financial development in different regimes have different effects on carbon dioxide emissions, so it is appropriate in situations where financial development reduces carbon dioxide emissions, strengthen financial development to achieve both economic growth and development and Environmental protection also happens.

The impact of the development of information and communication technology on the labor market and social security has been the focus of international labor and social security organizations. This study examines the impact of ICT on Social Security Resources in the context of Iran’s economy during the period 1999 to 2019, using the Stochastic Dynamic General Equilibrium (DSGE) model, focused on duality of labor market (formal and informal).  The results of the study show that the development of information and communication technology affects social security resources by changing the structure of employment. A survey on the variables response to the positive impulse of ICT shows that the further increase in job opportunities in the informal sector provides more access to jobs in this sector and increasing in the participation rate, the number of informal workers increases. The finding show increasing in informal employment causes an increase in the lost resources of social security. Based on the results, it is suggested that policymakers and insurance funds develop flexible programs in order to expand insurance coverage and support informal workers with the participation of employers and the government.

The information and communication technology are one of the major factors that impacts the labor market. It has always affected the nature and type of employment in the labor market, changing the type of employment from permanent, stable and formal to contractual, temporary, unstable and informal. Therefore, it is important to study the impact of information and communication technology on the labor market. This study examines the impact of information and communication technology on labor market in the context of Iran’s economy during the period 2009 to 2019, using the Stochastic Dynamic General Equilibrium (DSGE) model, focused on duality of labor market (formal and informal). The results of the study show that the development of information and communication technology impacts both formal and informal sectors through creating job opportunities, employment, production and consumption. A survey on response functions shows that an ICT impulse initially increases formal and informal employment, but the rate of formal employment decreases after a while, and the rate of informal employment increases. It will also shift the population outside the labor force in to the labor force population, contributing to the increase of labor supply.

The use of natural resource revenues for achievement of development has been challenging issue for resource abound countries. These a challenging stem from the fact that incomes from natural resources are non-durable, unpredictable and uncertain. Many countries have pursued approaches and tools for managing these revenues to prevent economic fluctuations. The international organizations and economic experts propose a diversification into resource revenues in the form of different approaches for public investment. The present study evaluates the policy of increasing public investment in Iran in the form of three gradual, aggressive and conservative approaches for the period of 1978-2015 using a dynamic stochastic general equilibrium method. The results showed that after an oil revenue shock, the status of economic variables in the gradual increase approach is better than the other two approaches. In a gradual approach, in addition to increasing GDP and private and public consumption, public debt is also declining.

The present paper examines the effect of culture on the relationship between income and carbon dioxide emissions in the framework of the Environmental Kuznets Curve (EKC) using dynamic panel and system GMM estimator for 77 developed and developing countries for the period 1990 to 2014. Results of estimation by system GMM indicate: (i) the existence of EKC, and (ii) significant impact of culture on the relationship between income and CO2 emissions. The impact of six dimensions of culture on EKC can be classified into two categories: (i) masculinity, power distance and indulgence move the EKC upward and shift the income turning point to the left; and (ii) individualism, uncertainty, and long-term orientation move the EKC downward while shifting the income turning point to the right.

Studies on the relationship between energy consumption and economic growth have mostly used per capita gross domestic product or GDP to measure economic growth. Such an approach cannot explain the increase in economic development and human development. This paper uses ARDL method and Bound tests to examine the relationship between per capita energy consumption, per capita electricity consumption and human development as a proxy of human well-being for period 1971 to 2011 in Iran. Results indicate that per capita consumption of energy in the short-term and in the long-term have a negative impact on the human development index. Per capita electricity consumption has a significant positive impact on human development in the short-term and in the long-term. Results also show that in the long-term, the impact of per capita electricity consumption is about two times the impact of energy consumption. Results of causality tests show a two-way causality relationship between energy consumption and human development and, a two-way causality relationship between electricity consumption and human development in the long-term.

This paper investigates the effect of modified human development on sustainability of economic growth for the period of 1980 to 2008 in developed and developing countries by using a system of simultaneous equations. Results of the estimations using a 3SLS method indicate that modified human development index has a positive effect on economic growth in the three groups of countries: the coefficient for high per capita income countries is 12.4; in countries with average per capita income it is 5.2; and it is 5.8 for countries with low per capita income. In other words, the effect of modified human development index on economic growth in developed countries is tow times higher than of developing countries. For the non-sustainability, results indicate that there is an inverse N relationship between non-sustainability and modified human development index in high per capita income countries; but for countries with average and low per capita income, there is a simple N shape relationship.
