This research investigates the effect of financial health and macroeconomic indicators on the profitability, efficiency and productivity of Iran’s banks. The statistical population in this research is private and government banks listed on the Tehran Stock Exchange. For this purpose, 20 banks were studied during the period 2013-2021, using the panel data method. The results of the data analysis show that the capital adequacy ratio has a negative and significant effect on the efficiency of the studied banks. Conversely, the quality of the bank's assets, the quality of the bank's management, and the quality of the bank's liquidity have a positive and significant effect on the technical efficiency of the bank. Moreover, the results indicate that interest rate, inflation rate, exchange rate and GDP per capita, as macroeconomic indicators, have a positive and significant effect on the technical efficiency of the bank. Financial health indicators such as capital adequacy ratio, bank assets, bank management quality and liquidity quality have a positive and significant effect on bank profitability and productivity. Macroeconomic indicators such as interest rate, inflation rate, exchange rate and GDP per capita affect positively and significantly the bank's profitability and productivity, while the exchange rate shows a negative and significant effect.

Due to the threat of Covid-19 to the public health of the world, the World Health Organization, in order to show international interest in coordinating international responses to this disease, raised the public health emergency and after that, the global issue of Covid-19 was declared. In a highly interconnected world with strong ties between countries, the effects of disease outbreaks go beyond mortality and morbidity. Because with the reduction of economic activities, the performance of the global supply chain will also be disrupted. Considering the importance of this issue and the destructive consequences of the spread of this virus on the global economy, it is necessary to take a step to reduce this problem. Therefore, the purpose of this study is to investigate and analyze the long-term effects of the human development index and its components (life expectancy, literacy, per capita income, urbanization and employment) on deaths caused by Corona in selected developing countries (30 developing countries). with a relatively high human development index) in the period of 2019-2022.

For this purpose, FMOLS and DOLS methods have been used.

The results indicate that the human development index and its components (life expectancy, literacy, per capita income, urbanization and employment) have a negative and significant effect on the death rate of Corona in selected developing countries in the long term.

Since the human development index has a negative and significant effect on corona deaths in selected developing countries in the long term, Therefore, the improvement of health, social and economic indicators can reduce the attenuation of Corona in societies. Therefore, it is necessary for governments to make interventions in the sectors of society, especially economy, education and security, in order to strengthen reforms in the health sector.

Energy is very important in the growth and development of countries. But the increase in energy consumption has caused environmental damage. Therefore, the use of renewable energy sources is a necessity. In the meantime, several components affect the use of this type of energy, of which social capital is one of the most important. In this regard, the present study was conducted with the aim of investigating the effect of social capital on the consumption of renewable energy in selected Islamic countries in the period of 2015-2022 and using the method of Dynamic common correlated effects. The results indicate that social capital has a positive effect on the consumption of renewable energy in selected Islamic countries in both short-term and long-term periods. Therefore, it is suggested that policymakers pay attention to the strengthening of social capital in selected Islamic countries. In this way, to speed up the transition to a revised energy consumption.

Among the growth and development of businesses, managing financial flows and increasing its effectiveness is an important achievement that causes value stability, efficiency of systems and procedures throughout the chains of Business. Therefore, paying attention to uncontrollable and controllable variables that lead to value creation is inevitable. The purpose of this study is to study the impact of social and biological factors (production and recycling of polymer parts) of environment on the value creation of the company along the supply chain. Also the key role of financial ratios has also been considered in this regard.The present research is of quantitative and applied types and is based on mathematical modeling. It is the result of a combination of genetic algorithms and Simulated Annealing. The financial analysis parameters of the model include current ratios, debt to equity, Instantaneous ratio, net profit margin, cash ratio and rate of return.The analysis of the results shows that considering financial goals and indicators leads to improved profitability and by removing financial indicators from the model, profitability is reduced. Therefore,this is means that the environmental and social performance of the supply chain is improved.Companies can pay special attention to social issues and environmental factors along with their profitability Increase their economic value. Profitability can also be improved by exposing social responsibilities and the mission of environmental protection.

Sustainable development through minimizing the negative externalities on the environment is one of the important topics of economic research in recent decades. The emission of carbon dioxide resulting from the combustion of fossil fuels in diverse sectors of the economy, which include industries, power stations, transportation, and even the household sector, as one of the externalities of human activities today, is known to be the cause of environmental destruction. This paper analyzes elements which affect the emission of carbon dioxide in MENA region countries, during 2004 to 2020 by expanding the spatial Green Solow model and using the dynamic spatial panel model (DSM). The results of the estimates imply that population growth, urbanization growth, the share of industry in the GDP and the degree of trade openness have a positive and significant effect on carbon dioxide emissions. However, no significant relationship was discovered between the two variables of democracy and physical investment with carbon dioxide emissions in the goal nation. On the other hand, the spatial correlation among sections was confirmed. In addition, the convergence of the factors affecting carbon dioxide emissions was confirmed in the investigation period, which means that nations have tried to reduce carbon dioxide emissions in the duration.

global warming and the greenhouse effect caused by the release of atmospheric pollutants and the subsequent threat to life on the planet have become one of the most important challenges facing governments and their economic decision makers. Emission of carbon dioxide from fossil fuels in industries plays a significant role in this pollution. Furthermore , in the countries that have sheltered the worn-out industries of the developed countries, the emission of carbon dioxide gas caused by the fuels used in the industry, inappropriate industrial infrastructure and high energy consumption are the main reasons that endanger the environmental conditions of these countries
this study has examined the effect of exchanges resulting from trade openness on carbon dioxide emissions in MENA countries during the period from 2004 to 2020. Meanwhile, by using spatial econometric techniques, it has paid attention to the mutual effect of countries on each other in the process of producing carbon dioxide gas. The results indicate the confirmation of the effect of spatial proximity and the positive effect of the degree of commercial openness on the emission of carbon dioxide in the studied countries.

Financial instability can lead to failure in financial markets and create macroeconomic costs. Therefore, by examining this harmful event, we can achieve conditions of economic stability and security. The main purpose of this study is to investigate the financial instability of Middle Eastern countries during the years 2000 to 2019 in a dynamic model and using a two-stage system of Generalized Method of Moments (GMM). To reach this goal, the index of instability and financial development was created on the basis of the influential variables of the banking sector and the stock market in two groups of oil exporting and non-exporting countries in the region. The estimation results show the different effects of variables on financial instability in exporting and non-exporting countries. Most countries in the region are oil exporters and the results of the estimate confirm the negative and significant impact of financial development and economic growth on financial instability. Also, in order to create a more comprehensive view, the control variables of the terms of trade, government spending and inflation have been used in the model. The first lag of financial instability and inflation variable have positive and significant effects and the terms of trade and government spending have negative and significant effects on financial instability. In oil non-exporting countries, due to less financial instability than exporting countries, the relationship between a number of variables and financial instability was not significant and different results were obtained. It is recommended that policy makers reduce financial instability by controlling prices and directing liquidity and credits to production, reforming the level and composition of government spending, and improving trade relations.

Financial development and stability and their relationship with economic growth is one of the most important and influential issues in economic growth. Therefore, economists have studied this issue by exerting different conditions. The main purpose of this study is to evaluate the impact of financial development and financial stability on Iranchr('39')s economic growth using the generalized method of moments (GMM) during 1992-2019. The results show positive and meaningful effects of financial development and financial stability on economic growth. The variables of lagged economic growth, education, fixed investment and trade liberalization have positive and significant effects on economic growth, while, inflation, government expenditure and active population have negative impacts on economic growth. Therefore, considering the important role of education, it is recommended to government to invest in this sector and upgrade the production structure, make the necessary structural reforms in the capital market and banking system, direct credit and liquidity to strengthen private sector production, as well as improve the level and composition of government spending in order to increase production efficiency.

The purpose of this paper is to examine the mechanism of monetary and fiscal policy transmission based on the framework of the new Keynesian model. The new Keynesian framework is a combination of the features of the dynamic stochastic general equilibrium of the real business cycle model and the Keynesian theory. In the New Keynesian dynamic general equilibrium model, the consumers face liquidity restriction and the firms face sticky prices. In this model, money has no obvious role. Of course, that doesn't mean money doesn't matter. Money is still the center of attention but invisible. The present paper studies the monetary policy rule jointly with fiscal rules through the estimation of a three-equation New Keynesian model (aggregate demand (IS), monetary rule, aggregate supply (Philips curve)). The presented model is estimated by systematic generalized methods of moments using Iran's data from 1989Q1-2017Q4. The obtained results show that the aggregate demand responds to the changes in interest rate and that the coefficient of consumers ‘consumption habits is significant. Also, inflation (regardless of its source) seems to be persistent and inertia. On the other hand, this research indicates that the monetary policy has a forward looking behavior; the output gap with a lag has a negative influence on government expenditure. The short term impact of output gap on government expenditure is less than its effect on taxation. That is tax reaction is positive and stronger compared to output gap reaction. Since monetary and fiscal policy can play a pivotal role in stabilizing the economy, it is recommended to implement a true and precise fiscal policy to pave the way for an active monetary policy using the new Keynesian model.

This research is designed and carried out to investigate the relationship between institutional quality, intellectual property rights and human capital with economic growth (case study of G7 countries). In this research, he studied the economic growth in the form of new theories of growth centered on institutional factors, and in addition to analyzing economic variables; Institutional variables in its two forms (economic institutions,property rights and political) were added to the model.Economic institutional variables are identified with the index of economic freedom and political institutions with the general title of rulers, which is based on six indicators of governance, of course, the index of democracy is The title of the political institutional variable was evaluated separately due to the different data source and the relative breadth of the discussion. The results obtained from the estimates made in this research indicate the important role of institutions in the economic performance of countries and the relevant coefficients show that good governance or in fact the institutions through which power is exercised in a country has positive effects on have economic growth and the coefficient related to the index of economic freedom and property rights as a positive economic institution is effective on economic growth among G7 countries.But in relation to the democracy index, as previous studies have shown,the effect of democracy on growth is ambiguous, but a relatively acceptable approach that can be relied on in this case is the indirect effect of democracy on growth through channels such as improving human capital

Sanctions are coercive contrivances that are applied by a country or a group of countries against another one which transgresses the international laws or contravenes the accepted ethical standards. The aim of sanction is to force the offender to cease its actions or at least to force the country to negotiate for ending its unaccepted actions. This study has been carried out to assess the effects of economic sanctions on the function of internal factors of small and medium size industries of Lorestan Province during 2001-2012. The study was performed in terms of five hypotheses. In order to collect data, the researchers used a questionnaire, the validity and reliability of which were confirmed by related tests. The questionnaire was distributed among the statistical population (managers of the small and medium industries of Lorestan Province), and 127 acceptable questionnaires were received. The data were analyzed by spss software and by using regression method. The results assert the existence of both positive and negative effects of economic sanctions on internal factors. While the sanctions have negatively influenced the performance of production, marketing and finance, they have improved the function of other internal factors such as management and research and development in the sample industries.
