Nowadays, banks are considered as one of the major components of the financial system of a country and any deficits and malfunction in the banking system will negatively affect the performance of the real sector. Therefore, there is a need for more investigation on the behavior of banks and factors affecting those behaviors in a country. One of the issues that affect the behavior of banks is symmetric information. Thus, the main aim of the present study was to investigate the impact of asymmetric information in the money markets on investment, production, and employment. Hence, based on the New-Keynesian framework, a Dynamic Stochastic General Equilibrium (DSGE) model was adopted in accordance with the structure of the economy of Iran. The designed model entailed nine sectors including households, firms, banks, the Central Bank, oil, the government, exports, imports, and other countries of the world. Moreover, the rigidities of the prices and wages, and the rigidities of the imported and exported goods were taken into account in the model. By using the Bayesian method and data gathered from Iran during 1974-2017, the parameters of equations were estimated and the impact of symmetric information was investigated. The results indicated that increasing the asymmetric information and reducing the honesty in the society through decreasing the resources available to the banks and increasing the cost of banks will lead to an increase in the profit of the facilities. Also, increasing the profit of banks concessional loans decreases investment, production, and employment.

Opportunity inequality and its relationship with economic growth is a concept to which not enough attention has been paid in the previous studies. This study attempts to investigate the effects of opportunity inequality index on economic growth in 15 developing and 15 developed countries over the years 1995-2015. Accordingly, the mean group (MG) estimator within the framework of panel data was used and a new index for opportunity inequality was created. Furthermore, the effects of opportunity inequality and its sub-indices on per capita GDP were compared with the results of the model when economic growth was a dependent variable. The results showed that inequality of opportunities and its sub-indices on economic growth and per capita GDP had different effects in the developed and developing countries.

The purpose of this paper is to investigate the optimal monetary and fiscal policies with emphasis on a non-inflationary exit from economic stagnation in Iran. In the first stage, Iran’s economy has been modeled in the form of a New Keynesian Dynamic Stochastic General Equilibrium model (NK-DSGE). After modeling and extracting the system of equations, the structural parameters of the model have been estimated by using seasonal data from 1989 to 2016 and also the Bayesian approach. The results show that monetary and fiscal expansionary policies increase production though they are associated with inflation. In the second stage, the optimal monetary and fiscal rules have been extracted from a social loss function, and accordingly the conditions of a non-inflationary exit from stagnation have been investigated. The results of the simulation show that the optimal monetary policy cannot by itself lead to the exit of the economy from stagnation without inflation. However, if this policy is applied along with an optimal fiscal policy, a non-inflationary exit from economic stagnation can be achieved.

Subsidies reform in Iran started in 2010 after the implementation of the Targeted Subsidies Plan. Increasing the efficiency and productivity of production units through price realization was a main objective of this policy. However, the resulting spike in input and output prices challenged the achievement of the policy goals. The main purpose of this article is to compare the efficiency of the dairy farms in Iran before and after the Targeted Subsidies Plan was implemented. We used a sample of longitudinal data over the years 1990, 1993, 2000, 2007, 2013, 2016, and 2019 covering 11 regions in 18 provinces and applied stochastic frontier analysis by imposing the monotonicity condition to evaluate efficiency and productivity of the farms. The estimation results show that the unrestricted production frontier is not monotonic in energy and labor. Therefore, imposing a monotonicity condition reduces estimation bias which is critical for policymaking. Unbiased estimation of productive efficiency resulting from imposing the monotonicity condition ranges from 0.72 to 0.86, depending on the region. Results also show a 17% reduction in the production efficiency of the examined dairy farms after the subsidy reform plan which is against the policy goals. The regional differences in the efficiency of intensive dairy farming indicate the need for the more regionally specific supplementary policy, in terms of support schemes and subsidy reforms.

The article is grounded on the rapid demand growth and supply constraints, which have imposed unprecedented pressure on water resources in Iran. Virtual water import has been recently discussed as a policy to tackle water scarcity and so the study calculates (with input-output technique) virtual water flows between Iran and European Union (EU 28) in 2011. The results show that Iran has been a net importer of virtual water in trade with the EU28, with net imports of about 667 million m3. The largest Virtual Water Export from Iran to the EU28 are respectively to Germany, Spain and Italy, which accounted for more than 74% of the total virtual water exports. By contrast, the Netherlands, Germany and Austria have been the largest virtual water exporters to Iran, with a total share of over 68.8% of the total. In any case, while Iran's virtual water import from the EU28 is about 2 times as much as virtual water exports, the value of Iran's imports from the EU28 is more than 7.6 times of its exports. An indicator developed shows that Iran's exports to the EU are high water-intensive but Iran's imports from the European Union are low water intensive.

The countercyclical monetary policy is a policy that economists recommend to adopt in order to slow down the economic fluctuations. The aim of this study is to address the question that, in the presence of fiscal dominance and considering institutional quality (IQL), what the optimal monetary policy should be during the business cycles? To find the appropriate answer, first, in the framework of a Dynamic Stochastic General Equilibrium (DSGE) model, proportional to the structure of the Iranian economy, the parameters of the model are derived. Then, considering fiscal dominance and institutional quality, the optimal monetary policy during the business cycles is calculated and by using the equilibrium parameters, using data of Iran during 1991:2-2016:1, it is calibrated. The results show that the optimal monetary policy during business cycles of Iran is a countercyclical monetary policy. The optimal monetary policy coefficient during the business cycles decreases by a decline in institutional quality and an increase in fiscal dominance. In addition, when the policymaker's goal is only stabilizing inflation, the optimal monetary policy is independent of the business cycles. In addition, when the monetary policy is assumed completely independent, the optimal policy coefficient takes the highest value compared to the other assumed conditions.

Examining society’s preferences for any change in the status of wetlands, can translate their direct and indirect benefits into monetary values and provide useful information for the policy makers and planners. Hoor-al-Azim Wetland (also Hoor-al-Hoveizeh) is one of the four large wetlands with an area of over 125 thousand hectares located in Khuzestan province located in southwestern Iran on its border with Iraq. In this study, using market-pricing method, the direct use value of the wetland including agriculture, horticulture, animal husbandry, fishing and hunting was calculated for the year 2015. Also, using choice modeling analysis, indirect use values, option values and non-use values of the wetland were estimated for the non-market attributes including natural landscape, ecological function, biodiversity and education services. The values obtained are indicative of the value that Hourol-Azim wetland has for the society. Therefore, any conservation program of the wetland is supported by the society.

Covid-19 has affected the world’s economy since 2019. The coronavirus pandemic is one of the most severe and dangerous problems that humanity has faced in the last century. Therefore, this paper aims to investigate the impact of Covid-19 on the inflation rate in the 36 OECD member countries. Monthly data on Covid-19 and the inflation rate from February 2020 to August 2021 and the quantile panel regression method have been used to achieve this purpose. The results show that new cases of Covid-19 decrease the inflation rate in all quantiles, which means that by increasing the number of Covid-19 cases, economic activities decrease because of the business restrictions. Moreover, the new deaths of Covid-19 have a dual impact on the inflation rate in OECD countries. With increasing in Covid-19 deaths, business restrictions have increased, the economy has entered a recession, and inflation has decreased. On the other hand, the growth of Covid-19 casualties could increase economic uncertainty and inflation. Furthermore, Covid-19 vaccinations have positive and significant effects on the inflation rate in OECD countries. Accordingly, policymakers are advised to include increasing vaccine injections, especially booster doses, to increase economic activity and prosperity in OECD and world economies. Furthermore, Covid-19 showed the necessity of preparing the world against infectious diseases in the future.

It is obvious that an optimal policy should consider main dimensions of the phenomenon that can affect the transmission mechanism of that policy. In an open economy, it is expected that variables of the foreign sector play important role in its economic behavior. Therefore, it needs that any optimal policy in an open economy to design in such a way which involves changes in the foreign sector. Due to this fact, this paper aims at assessing the monetary policy of Central Bank of Iran to find that whether this policy takes a right way or not. To do so, a DSGE model along with MCMC criteria are employed.The main result indicates that the Central Bank decision on monetary policy follows McCallum rule without any respond to exchange rate shocks.

Abstract On 6 December 2006, Australia and Korea announced a joint study on a possible Australia-Korea free trade agreement (AKFTA) to promote trade and economic relations between the two countries. The paper provides empirical evidence on the possible gains and their transmission mechanism from this agreement. Significantly, it uses a new economic policy modelling approach, the endogenous gravity theory (Tran Van Hoa, 2004) to provide credible and substantive causal findings and subsequent forecasts, as distinct from geopolitical economy arguments and scenarios, to evaluate the possible gains of the AKFTA to inform discussion and policy advice.

Energy plays a significant role in today's developing societies. The role of energy demands to make decisions and policy with regard to its production, distribution, and supply. The vital importance of energy, especially fossil fuels, is a factor affecting agricultural production. This factor has a great influence on the production of agricultural products in Iran. The forecast of the consumption of oil products by the agricultural sector can help managers and planners to adopt sound management practices for their consumption. Presently, artificial neural networks are regarded as a powerful tool for the analysis and modeling of nonlinear relationships. The present study employed GMDH and RBF artificial neural networks to estimate the consumption of oil products by the agricultural sector. The underpinning parameters were selected to include the value added to the fixed price, rural population, agricultural land area, agricultural mechanization (tractor), and the consumption rate of oil products, electricity, price of oil products, and total energy use by the agricultural sector for the period of 1967-2017. The comparison of MSE, MAE, and MAPE for the GMDH and RBF models showed that the GMDH neural network was highly capable of modeling the energy consumption of the agricultural sector.

Domestic innovations and technology imports play important roles in boosting relative demand for skilled labor force. These factors are in turn influenced by domestic R&D investments and international trade. Using a translog cost function, this paper studies the effect of technology imports and other factors including output level and physical capital stock on the shares of skilled labor force employment. The data for technology imports are gathered based on ISIC (International Standard Industry Classification) 2-digit codes for the period 1971-2013. Our translog cost function is estimated by seemingly unrelated regressions (SUR) method. The estimation results show that an increase in technology imports raises the share of skilled labor force and decreases the production cost. Moreover, our result indicates that domestic R&D has no effect on employment level of skilled labor force in Iran.

Given the 95% share of electricity generation from non-renewable energies, implementing effective policies to motivate electricity generation from sustainable energy resources is essential. Since the current Feed-in Tariff (FiT) policy increases the government’s expenditures to support renewable energies, a real options (RO) model is proposed to estimate solar power generation incentive subsidy. Moreover, establishing a carbon emission trading (CET) scheme under uncertainty is proposed, and sensitivity analysis is conducted for the project value, threshold value, and subsidy. Our results show that establishing a CET market could significantly reduce the economic costs of achieving renewable energy promotion goals. Based on the net present value (NPV) and RO criteria, in the case “with the possibility of CET,” the amount of incentive subsidy that should be paid to electricity generation from a solar project (case of a 5 kW plant) are 37.49 and 42.42 million Rials/kW, indicating 20% and 12% reduction compared to the base case (without the possibility of CET), respectively. The results also indicate that more electricity price volatility can increase the incentive subsidy while enhancing the market price of electricity can slightly decrease the required subsidy, which triggers solar investment.

There is a long tradition in economics about the question of whether intergenerational discounting is fair or not. Ramsey (1928) was the first economist that criticized the discounting and mentioned that the just rate of discounting is zero. In this paper it was tried to calculate the just rate of discounting for Iran with respect to Islamic thoughts. According to Islam, intergenerational justice had been regarded when oil revenue was totally invested in other kinds of capital. So, we tried to calculate the social discount rate for Iran in current situations and after imposing the Islamic condition of intergenerational justice an overlapping generations’ model was used. Finally, our calculation showed that the value of social discount rate is 0.04 before imposing the intergenerational justice condition and -0.014 after it. Then, it was explained that in current economic situations of Iran, the best social discount rate which can satisfy the intergenerational justice, was an amount between zero and minus one.

This paper estimates the effects of increase in Iran’s non-oil exports on its economic growth as well as sectoral outputs, using a single country, comparative static, exogenous policy Computable General Equilibrium (CGE) model. The paper also investigates the share of tradable sectors in reaching to the targeted growth rate (8%) in 5th socio-economic development plan. For this purpose, the parameters of the model are calibrated based on Iran’s Social Accounting Matrix (SAM) which carries a snapshot of the Iran’s economy. The model is then used to simulate the impact of increasing the exports uniformly across all sectors by 10, 20, and 30 percent on endogenous variables, including sectoral outputs, and GDP. Results suggest that 2.03% of targeted economic growth rate would be achieved by encouraging a 6% growth in exports. Our founding also indicates that industry and mine sector in Iran, would have more influence on growth than other non-oil sectors.

Government expense is an important financial tool for empowering the poor. In such a way that the government provides a suitable environment for the business of people by investing in the fields of defense, judiciary, legislation, order and security. In addition, by providing social services such as education, health, social security, and transportation, communication, energy and infrastructure, the government causes an increase in human capacity for earning more money leading to the reduction of poverty and inequality. The purpose of this study is to estimate the optimal amount of government expenses in economic, social and cultural, defense and security, public affairs. Related chapters aim at minimizing income inequality. In this regard, the threshold regression model and the simplex linear programming algorithm are used for estimating the time series data during the period 1971-2019. The results reveal that the optimal amount of government expenditure total should be equal to 19.2% of GDP to reduce the income inequality. Also, for reducing the income inequality, the optimal amount of public, defense, social and economic expenses in GDP should reach 1.1, 2.35, 10.2 and 5.5 percent, respectively. Moreover, among the chapters, the optimal amount of education, health and defense chapters with the highest priority should be 6.5, 2.25, 1.79% of GDP, respectively. Furthermore, other chapters have different effects on income inequality.

This paper presents an economic evaluation of gas to liquids (GTL) project using “South-Pars” gas field of Iran based on the latest actual performing GTL projects. Iran has the world’s largest reserves of natural gas and can satisfy the projected long-term market demand of GTL products which have lower pollution and higher quality than refinery products. The results of cost-benefit analysis show that GTL project in Iran is fully economical. Sensitivity analyses are conducted and the results show that the capital expenditure is the most sensitive factor in this project, followed by the price of crude oil and the price of feed gas respectively.

The banking sector is one of the important financial intermediaries in an economic system. Improvement in the banking sector can achieve optimal allocation of financial resources. The performance of banks and other financial service providers has direct effect on economic growth. One of the factors that can affect the banks operation is economic freedom. Economic freedom and freedom of private property rights can influence the quality of financial institutions such as banks. Using panel data model, this paper attempts to study the effect of the economic freedom index on the performance of banks in selected developed and developing countries for the period 2001-2011. According to our finding, countries with higher degree of economic freedom index have better financial performance. Moreover, economic freedom indexes have positive effects on bank′s profitability in both groups of countries.

Although the implementation of targeted energy subsidies plan has been considered by policymakers since the First 5-year Economic, Social and Cultural Development Plan in Iran, it is only partially implemented in 2010. This issue has great importance for industry sector that has benefited from subsidized energy prices. This research attempts to investigate the possible impact of implementing Subsidy Reform Plan on manufacture of non-metal mineral products industry by using Artificial Neural Network approach. This investigation focuses on new entered firms into this industry as one of the most energy intensive industries. The results indicate that by replacing subsidized prices with electricity real price, the consumption of this energy carrier will generally decline by 16 percent. Despite this, the large entrance of new firms has raised the energy consumption in some years. Therefore, the results show that targeted subsidies plan does not have a large impact on energy consumption in non-metal mineral manufacturing industries. Furthermore, we find out that the impact of this policy depends on combination of firms in each industry.

The main objective of this paper is to investigate the effects of technology transfer through the imports of intermediate goods by developing countries developed countries with the emphasis on Iran economy. For this purpose, we used multi-sectoral and multi–regional computable general equilibrium GTAP model (multi-sectoral and multi-regional CGE model). The paper examined the effect of a ten percent productivity shock in high-tech industries of industrial countries on economic sectors of Iran. The result shows that technology transfer embodied in Iran’s imports of intermediate goods leads to increase in outputs and decrease in prices. Factors such as absorptive capacity, structural similarity and effectiveness contributed to the spillover effects of technological improvements in Iran.

The ICT is one of the main determinant factors of e-commerce industry such as tourism industry in developing countries like Iran. For this purpose, the main objective of this paper is to investigate the long-run relationship between ICT indices such as internet users, government expenditures on ICT to the GDP and mobile cellular in Iranian economy during the 1976-2014. The empirical model has been estimated by applying FMOLS co-integrating method as a sophisticated econometric methodology. The results of empirical results indicate that there is a long-run relationship between ICT indices and tourism demand indicators like number of tourist arrival in Iran. Moreover, the other explanatory variables such as living cost, real exchange rate and behavioral habit have negative and positive effects on the tourism demand respectively. The investment of government in ICT indices such as improving the share of ICT expenditures in GDP and enhancing the ICT quality are the important policy implications of this study

Oil and Gas sector, with notable participation in national product and funding public expenditures, plays a seminal role in Iran's economy. Although there is a relative lag in providing proportionate supply, Iran stands at the highest rank of owning world's related proven reserves. Using a Computable General Equilibrium (CGE) model, this study was aimed to investigate the effects of the increase in the acquisition rate of Iran's oil and gas upstream affairs from oil revenues on GNP and public budget, which are supposed to help the government keep its main obligations often funded from oil revenues. By applying the 18% gain, instead of the current 14.5%, to the oil and gas upstream affairs, short-run recession against long-run booming effects would emerge. Accordingly, maintaining the initial level of either the Public Goods and Services (PGS) output or Government Financial Supports on PGS, GNP could boost up to 5% with over 15% of required contraction in the public budget. On the contrary, maintaining the initial level of either the Transfer Payments or Transfer Payments and Financial Supports on PGS (simultaneously), GNP would rise only 1%, due to the negligible required contraction in the public budget. Therefore, allocating more oil revenues to developing upstream affairs (even under the presence of the contemporary main obligations) is recommended due to its potential to spur notable growth in GNP.

This paper focuses on strategic trade policy in the form of export subsidies in Cournot duopoly structure for differentiated goods. Export subsidies affect social welfare in both static and dynamic situations , and the aim of this paper is to analyze and compare the welfare effects of export subsidies in one-period and multi-period games in differentiated goods markets. To analyze the welfare effects of export subsidies, a two-stage game of complete but inperfect information is considered. In the first stage, two governments determine the amount of export subsidies and in the second stage, two firms determine the product level. The results show that, given that the firms’ competitiveness do not differ so much, export subsidies by both governments increase the firms’ profits and decrease social welfare of both countries. In an infinitely repeated game with different discount factors for both countries, and by adopting trigger strategy, we create some conditions, in which both governments commit free trade. However, if the competitiveness of one firm is so greater than the other, free trade using trigger strategy is not stable and the country with more competitive firm has incentive to deviate.

The Earth's temperature has climbed by 0.7 degrees Celsius (°C) during the last 100 years, and the worldwide average temperature is expected to rise between 1.8 and 6.4 degrees °C by 2100. Climate change, particularly rising temperatures, according to IPCC , the Middle East and North Africa (MENA) area will face challenges throughout the twenty-first century. As a result, the study's aims are to evaluate the impact of policies which eliminate or targetize fossil fuel subsidies in order to reduce global warming, as well as the impact of these policies on economic variables (GDP, consumption, capital accumulation, employment, and environmental impact) in the MENA until 2100. For this purpose, a Dynamic Regional Integrated Climate-Economy Model (RICE) is utilized to do this. The findings suggest that in the long run, if no strategy to limit temperature rise is enacted and carbon subsidies persist, the average world temperature would rise by 4.74 degrees °C, while an optimal policy based on fossil fuel taxation will increase the average global temperature by 4.49 °C, and a policy reforming fossil fuel subsidies will increase the average global temperature by 4.24 °C. Generally, carbon tax measures in the MENA area will lower average world temperature increase by 0.5°C compared to other scenarios.
