Principal Component Analysis (PCA) and Artificial Neural Network (ANN) methods were used to obtain this composite index. This study used six environmental indicators from two groups of Organization of Petroleum Exporting Countries (OPEC) and Organization for Economic Cooperation and Development (OECD) during 2008-2019. According to the obtained error criteria related to the two methods, ANN method was used to calculate the weight of environmental indicators due to having the lowest error criteria and therefore reliable results. Finally, using this composite index, the trend of economic growth and environmental quality were analyzed graphically. The results showed that along with the upward trend of economic growth, the quality of environment follows a downward trend in OPEC countries and an upward trend in OECD countries. At the end of this paper, some limitations of study are presented, and some suggestions for future studies are provided as well.

On the other hand, the issue of budget deficit was introduced in economic literature since 1980s. Within this decade, current budget deficit significantly increased in the USA. Emerging of this phenomenon prompted many economists to establish public sector as the macroeconomic unbalancing factor, on the contrary to Keynesy who regarded public sector as the balance factor, particularly in developing countries since developing countries deal with specific problems such as foreign debt, high inflation, difficulties of payment balances, exchange parallel markets as well as various external shocks. Therefore, this research tried to study the effect of growth, efficiency and government budget deficit in MENA selected countries within 2000-2013 by using the recommended static panel models. Results of the estimated relations for the first model in which government budget deficit is the dependent variable indicate positive effect of economic growth and inflation rate variables as well as the negative effect of labor productivity and government budget deficit. Moreover, the second model in which economic growth is the dependent variable demonstrates the positive effect of labor productivity index and economic growth. In addition, negative correlation of government budget deficit with economic growth is also maintained.

This issue is a major challenging one in the economic–environmental literature. This study investigates the role of financial development in economic growth effect on the composite environmental quality index (CEQI) in two groups of selected Organization of the Petroleum Exporting Countries (OPEC) and Organization for Economic Co-operation and Development (OECD) countries. In this regard, System Generalized Method of Moment (SYS-GMM) is applied to fit the research models. According to the findings, in the selected OPEC countries, financial development reinforces negative impacts of economic growth on environmental quality. In the selected OECD countries, economic growth has negative effect on the environmental quality and financial development weakens this effect. The effect of financial development on the CEQI is respectively negative and positive in OPEC and OECD countries. Moreover, in both groups of selected countries, energy consumption and economic growth have a negative impact on the CEQI; nonetheless, trade openness has a positive effect. Accordingly, some policy suggestions and new recommendations are presented for future studies, which would contribute to the better implementation of economic–environmental policies.

Previous studies only employed a single environmental indicator for analyzing the correlation between economic factors and environmental quality. However, six environmental indicators are adopted in this study to evaluate environmental quality and to reach major goals of this research. To this end, using 2-stage system generalized technique of moment estimator, the association of economic growth, energy consumption, financial development, environmental indicators, and trade openness is determined in selected OPEC countries for years 2010 to 2019. Findings indicated that accompanied by the effects of economic growth on any EFI, ANS, PN, and EPI variables, the financial development enhances such effect. This is while, the financial development would weaken the economic growth effect on the ESI variable. Regarding EVI, no significant association was observed. Regarding to ESI, EPI, and PN, trade openness applies a significantly positive impact on environmental quality; on the other hand, it has positive role in environmental degradation based on EFI and ANS. This is while, according to the EVI variable, trade openness has not meaningful impact on environmental status. Finally, energy use has significant and positive effects on environmental degradation in each of environmental indicators. However, this variable has not shown significant impact on EPI and ANS. Alternatively, findings indicated that financial development can be considered an important and key variable in improvement of the environmental quality due to the moderating role it plays relative to the negative economic growth effect on the environmental quality. At the end of this paper, some limitations are presented, and some suggestions for further studies are provided as well.

The present study will answer the following two questions. 1- Is increasing the share of ICT sector in GDP necessary? 2- How much does the economic growth change with one percentage increase in share of ICT sector in GDP? To answer these two questions, contribution of ICT sector on economic growth in Iran is first calculated through two methods of actual and potential contribution and then compared with each other. The results show that average GDP growth in Iran is about 3.8% for the period of 1990-2015 and, based on growth accounting, the potential contribution of ICT on economic growth is about half a percent. Actual contribution of ICT sector...

Because of that, it is of sensitive role in national economy. In addition to implementing dictated monetary policies of central banks, they as any economic business, pursue the goal of increasing their profitability. In this study, we use Dynamic Stochastic General Equilibrium (DSGE) and take into account five economic sectors, namely households, entrepreneurs, mediator banks, distributors and government, to study the reaction of banks to emergence of monetary shocks. For this purpose, the authors seek to make use of long-term macroeconomic parameters. The results of our model show that, upon emergence of a positive shock on interest rate, due to the decrease of request for loan and the amount of lent money, the rate of loaning and as a result, the profit of banks is reduced, and in the case of a positive oil shock, ...
