In macroeconomics, the Okun's Law and Verdoorn's Law are used as methods for studying the relationship between economic growth and unemployment and employment. The necessity of studying these two laws together, in a threshold econometric model and considering to regional and spatial conditions of variables, can have more effective results in labor market policies. Therefore, in this study, due to the importance of employment and unemployment issue in Iran, have been investigated economic growth thresholds in the Okun's and Verdoorn's Law, using Panel Smooth Transition Regression and considering to spatial and non-spatial dimensions of variables. The results of model estimation for 30 Iranian provinces of during the period of 2005-2017 show that unemployment response to changes in production growth was higher than employment, this is true not only in non-spatial state, but also in spatial state and calculation of proximity matrix in economic growth. In addition, the results in spatial state than non-spatial state with stronger and faster changes, which is evidence of regional labor markets impact and macroeconomic situation and unbalanced development in each region, which has led to overflow in other areas. Of course, these effects, with crossed of threshold and entering second regime, have led to improvement in the labor market to increase employment and reduce unemployment, but effects of economic growth more have been on reducing unemployment than employment growth.

The main objective of this study is to examine the effect of revenue-neutral change in the tax structure on economic growth in Iran using data for the period of 1361-1395. To this end, an empirical model has been proposed to analyze the effect of substituting different tax items for each other on economic growth in such a way that the total tax revenue remains constant. The results of cointegration analysis based on the autoregressive distributed lag (ARDL) approach show that a revenue-neutral transfer of indirect taxes to income tax or wealth tax increases economic growth in the long run. However, a revenue-neutral transfer of indirect taxes to corporate taxes reduces economic growth in the long run. Also, among direct taxes, a revenue-neutral transfer of corporate taxes to income tax or wealth tax as well as a revenue-neutral transfer of income tax to wealth tax promote economic growth in the long run. Furthermore, the findings indicate that the highest and lowest increase in economic growth correspond to the substitution of wealth tax for corporate taxes and of income tax for indirect taxes, respectively. The results of this study have important policy implications for tax structure reform in Iran's economy.

Abstract: The main objective of this study is to investigate the effect of Types the renewable energy production on Iran’s economic growth during the period of 2008-2017. For this analysis, Vector Autoregressive Model, Johansson-Juselius method and Vector Error Correction Model are used. In accordance with the obtained results, the effect of the variables’ coefficients is coincident based on the theoretical foundations and statistically significant. The results indicate that in the long run, the variables of renewable energy investment by the private sector, the power generation from the renewable energy, and the consumption of renewable energies, which are considered as indicators for renewable energies, have a positive and significant effect on the economic growth. The coefficient of the error correction method indicates that about 0.62 of the short-term imbalance is adjusted in each period to achieve the long-term equilibrium. Further, in the long run, a one percentage increase in the labor force variables, renewable energy investment by the private sector, electricity generation from renewable energy, and the Production of Types renewable energies) Wind, Solar, Hydro and geothermal) leads to 0.87, 1.17, 6.44, 4.29, 2.09, 1.78 and 1.56 percentage increase in the economic growth, respectivel and it became clear that It was found that among renewable energy sources, the effect of wind energy on growth is higher than other energies and we have to prioritize investment in wind energy. Therefore, according to the results of the research, the political recommendation is that, considering the process of the types of renewable energy sources in Iran, since wind energy has the greatest effect on economic growth compared to other energy sources. By investing in this unit, the share of renewable energy use in Iran could be increased Key words: Renewable energy, Economic Growth, Vector Error Correction Model and Johansson-Juselius method JEL: O13, C13, G21, C22

Banks due to their ownership structure have specific objective in granting credits. Hence, Ownership structure can be impact on economic growth by Influencing banks' lending behavior. Purposes of this study are investigating the role of bank ownership in the impact of bank credit on economic growthwith considering income level of provinces. This research is divided banks into state and private also divided provinces into two groups of high and low income. Econometric model of this research is estimated using panel data in 31 provinces during of 2006-2015. Descriptive analysis results showed that average of total credits each year, 21 percent by private banks and 79 percent by state-owned banks is paid. The findings of the model estimation indicate that the impact of both types of banks credit on provinces' economic growth was higher in low income levels compared to provinces with high income levels. The results of the tests conducted to measure the difference in the impact of two types of banks in each region indicated that state banks, with a significant difference compared to private banks, had a greater effect on economic growth in lower-income provinces. But the difference in the effectiveness of two types of bank credit on economic growth in provinces with high income level is not significant. Therefore, structure of bank ownership has effective role on the impact of credits on economic growth due to the income level of the regions.

The aim of this paper is examining the simultaneous impact of good governance and government spending on economic growth in MENA countries. To estimate model, we've used GMM method during 2002-2016. The results show that good governance (weighted average of six indexes) and government spending have positive and significant effect on economic growth. GDP last period and trade openness variable have positive and significant effect on economic growth. Inflation variable has negative and significant effect and private investment variable has positive and insignificant effect on economic growth. The effect of both economic growth and government spending is positive and significant. Good governance index resulted from combination of existing six indexes by Principle Components Model, has been estimated in another model and it indicates positive relationship with more effect on economic growth.

In most previous studies concerning investigation of factors affecting economic growth, spatial dependencies have been ignored which would result in biased and inconsistent estimates. At first, economic growth of a country is influenced by its own geographical, internal conditions and capabilities then affected by the spillover effects of neighboring countries and its trading partners, which these influences by others on growth of a country are called spatial effects and spatial dependencies. Therefore, this study examines the factors affecting economic growth by using the spatial dynamic panel method in both developed countries (members of the Organization for Economic Cooperation and Development) and developing countries (members of the Economic Cooperation Organization) during the 2001-2015 period. The innovation of current research is to use dynamic matrix derived from bilateral trade of countries, which varies over time. By estimating spatial growth model, positive spillover effects from one country to its trading partners have been confirmed in both developed and developing countries. By comparing the results, only the physical capital factor has contributed to improving the growth of developing countries, while in developed countries, in addition to physical capital, two factors including human capital and trade have provided further growth. In order to capture positive effects of trade on advancing economic growth of ECO countries, it has been suggested to consider political and institutional changes in economic development programs.

In an economy system, government activities play a fundamental role in economic growth and development of countries, but increase these activities have a positive effect on economic growth until a certain threshold and from this threshold excessive increase in government activities not only have no positive effect on economic growth, but these activities are main barrier to growth. Including of these activities, can mention the government''s capital expenditures and public debt. In this study, is tried to study the threshold effects and non-linear government investment and public debt on GDP in two separate models during of 2000-2016 using of provincial data and Panel Smooth Transition Regression Model (PSTR). The results of linearity test show that there is a nonlinear relationship between variables. Also, the inclusion of a transfer function with a threshold parameter which is representing a two-regime model, is sufficient to determine the nonlinear relationship between variables. The results show that public debt and investment in first regime have a positive effect on GDP, but by crossing of threshold and entering to second regime, severity of this effect will be increased and negative. It seems, this result is due to the crowed-out effect on private sector and increase in public debt due to rising government spending and confirms Laffer curve hypothesis.

Planning and policy making in the field of economic growth as one of the major macroeconomic goals requires special attention to the energy sector, the environment and its relation to production. Hence, in this paper, the effects of energy consumption shocks on carbon dioxide emissions and economic growth in selected countries of the MENA have been studied using the PVAR approach as well as Iran using the VAR method, and the results indicate that the energy shocks would initially lead to a relatively high increase and then a decrease in per capita GDP in the selected countries. The energy shock also initially increased carbon dioxide emissions and subsequently reduced pollution in subsequent periods and will move to the balance in long-term; also, in the Iranian economy, a shock to energy consumption first begans to sharply increase in economic growth after four periods, and eventually returns to a long-term equilibrium. Eventually, with a shock in total energy consumption, carbon dioxide emissions are mildly increased and then begin to decrease from the third period. Total energy consumption, foreign direct investment, labor force, and capital stock have a direct and significant relationship with economic growth, but carbon dioxide emissions have a significant negative relationship in Iran's economy.

Investigation of factors that affect economic growth has been always attractive. Foreign direct investment is one of the variables that have potential effects on growth. This study carried out to investigate the impact of foreign direct investment on economic growth. We consider the role of natural resources using panel threshold regression model for 1996 to 2015 period and also emphasis on relationship between foreign direct investment and economic growth in Iran by Markov Switching Approach for 1976-2015. Panel threshold regression model formed based on Hansen’s (1999) suggested model then that estimated by Wang’s (2015) proposed method for fixed effect models. Results of threshold regression model showed that natural resources, domestic capital formation, population growth rate and governance indicator has statistically significant effect on economic growth. Threshold level for natural resources is 28.58 percentages. Foreign direct investment variable has different effect on economic growth in regimes. In first regime foreign direct investment increase economic growth but in second regime, that natural resources is more than threshold level, it decrease growth rate. Results of tow regimes Auto-Regressive Markov Switching model for Iran showed that foreign direct investment in recession regime is insignificant but this variable in boom regime has statistically significant effect and this relationship is negative.

In this paper, government expenditure productivity has been studied in selected countries that are member in Organization of Petroleum Exporting Countries (OPEC) and optimum threshold government size of these countries is determined. For this reason, endogenous Barrow growth model is used that practically applied by Karras. Panel data threshold approach is applied. The reason for selecting these countries for study is that these countries have the same government financial structure such that a high share of budget of these countries depend on the oil revenue. According to available data, eight countries are selected and the period under study is from 2000 to 2014. Estimation findings show that optimum threshold government size of these countries have been estimated 13/58. In addition, findings indicate that before the threshold government size, the productivity of government size has been positive and approximately 0/72 and after the threshold government size, the productivity of government size has been negative and approximately -0/23.

The current study, using the VAR model, tries to explore the effects and consequences of economic instability on economic growth in Iran during the 1981-2011 periods using the principle components analysis. In this study, using the principle components analysis (PCA), an indicator of economic instability was built and then the impact of this indicator on economic growth of Iran was examined. The findings show that Only the importance of labor in the Agricultural sector but in other sectors more than other variables, physical capital is the more important in explaining economic growth. In all areas of macroeconomics, variable economic instability negative impact on economic growth in the sector. Four parts macroeconomic indicator of economic instability in the analysis of variance, respectively, in the fields of Industry and Minerals, Services, Agriculture and Oil and Gas exploration is more important.

Macro-economic relationship between fiscal policy and economic growth has long been considered by economists. In this study to evaluate the more accurate effect of the government's fiscal policy in the economy, using quarterly data for the years 1988 to 2016, a factor-augmented vector autoregressive (FAVAR) model with time varying parameter model (TVP) in Iran's economy has been modeling. The variables of GDP growth, investment growth, inflation, exchange rates, the growth of private consumption expenditure and latent variable of government fiscal policies are used in model. Based on results the effects of fiscal policy on economic growth in the whole period is positive and investment increased the rate of economic growth. Also the additive positive effects of fiscal policy on the unofficial exchange rate has increased over time. In addition, the effect of fiscal policy on inflation is positive, so that the additive effect in economic prosperity period is more. Finally, the effect of fiscal policy on private sector spending is negative. Results of this study show changes in relationships between variables over time and also indicate that economic conditions of the country affects the impacts of independent variables.

The inverse relationship between economic growth and unemployment rate is known as Okun’s law in the economic literature. According to the importance of Okun's law on economic policy, investigating the relationship between unemployment rate and economic growth is very important at provincial level. Also, with regard to labor mobility between provinces based on economic conditions, spatial and spillover effects are essential in regional studies; therefore, the main objectives of this paper are to investigate Okun's law in Iran's provinces with spatial econometric approach and whether Okun’s law can be used as a rule of thumb for surveying the labor market response to changes in regional economic growth, in Iran's provinces. A panel data set for 30 provinces during period of 2005 to 2013. The results show that unemployment rates and economic growth of provinces have spatial dependence and labor market performance is influenced by macroeconomic situation and its features the economic situation in neighboring provinces. Hence, in this study spatial panel is employed to investigate Okun’s law. The results of spatial panel (SAC) approve accuracy of Okun's law in Iran's provinces; and the development of regional labor market is not limited to the provincial borders and spillovers to other provinces.

The level of GDP and its growth rate are the most important performance indices in macroeconomics. Therefore, investigation of the effective factors on economic growth is especially significant and one of the most important issues in the field of macroeconomics. The review of literature related to economic growth, showed that granularity in banking is one of the effective factors on economic growth. This paper has studied the simultaneous effects of trade openness and granularity in banking on Iran’s economic growth. Generalized Method of Moments has been used to test the hypotheses. The data has been used in this research is Iran macroeconomics data and data related to Iran Banking network in the years 2001-2012. As expected, The results show that bank granular residual variable and simultaneous effect variable of trade openness and bank granular residual have a negative and significant effect on Iran’s economic growth.

The relationship between foreign direct investment and economic growth is an issue that has always been of importance for economists. It is believed that foreign direct investment (FDI) is necessary to promote economic growth and capital formation in every country, particularly in the developing countries. Since it has been discussed that FDI promotes economic growth not only by increasing the volume of financial funds and relaxing the constraint on investment financed by domestic savings but also by technology and management skills transfer from advanced economies to developing economies in the context of endogenous growth models, it is necessary to examine the effect of FDI on economic growth via the above mentioned channels. In this study, we examine the effects of FDI on capital formation, labor productivity and economic growth. We try to test the hypothesis that FDI helps economic growth in developing countries not only via capital formation but also via the increase in productivity. To test this hypothesis, we use a panel data approach in a simultaneous equations system including three equations and three groups consisting of 111 developing countries over the time period 1995-2013. Our method of estimation is 2SLS. Our results show that in the sample we have examined, productivity has a higher effect on economic growth than capital formation. Therefore, the hypothesis that “FDI, by increasing productivity, has a positive effect on economic growth” is not rejected.

Post Keynesian growth model considers the use of production factors as a function of production and introduces demand as the main determinant of economic growth. Accordingly, Thirlwall (1979) presented a model suggesting that demand is restrained by the balance of payments deficit and turns into substantial limitations to achieve higher economic growth rate owing to balance of payments deficit. This model is known as Thirlwall law or “balance of payments constrained growth model”. In this model the maximum rate of economic growth consistent with the balance-of-payments equilibrium is figured out using income elasticity of import and export. Identifying the barriers to achieving the target growth rate has been turned into one of the most controversial economic issues because of the challenges of low economic growth in Iran. Thus this study is going to provide an answer to the question that, based on Thirlwall law, Whether the balance of payments deems obstacles to the target growth rates of development programs for the Iran’s economy or not? To accomplish this, first the long run cointegration relationship of import and export demand functions was approved by autoregressive distributed lag model (ARDL). Then, regarding the importance of the elasticities of above functions on the results of the study and removing the structural instability of the model coefficients, time–varying parameter (TVP) and Kalman – filter were used to estimate the elasticities. Finally the validity of Thirlwall law was not confirmed during 1984-2013 applying Wald Test. Therefore, it can be claimed that aggregate demand has not restricted the economic growth through the balance of payments. Low income elasticity of import, combination of imports, restrictions on imports and dependence of foreign trade on oil revenues are the most important reasons for the results.

This study aims to measure the external efficiency of formal education and then evaluating the effects of economic growth in Iran during 1957 to 2013. External efficiency, is the responsibility of educational system to social system in term of individual, economic, political and cultural dimensions. The research method to measure the relative efficiency is the Data Envelopment Analysis (DEA) method with the input-oriented and constant returns to scale, and efficient units are ranked using Anderson-Peterson (AP). Using the econometric method of GMM to evaluate the effect of the external efficiency of education on the economic growth. Results showed that in 85 percentages of examined years, external efficiency of education is acheived. Inputs that affect respectively on the external efficiency are educational equity, technology infrastructure, education expenditures and quality. Outputs that affect respectively on the external efficiency are freedom, environment protection, family sustainability and establishment. For inefficient units, the most of output shortage related to security and maximum output surplus is for education expenditures. External efficiency of education, labor and capital have a positive effect on economic growth in Iran and external efficiency of education is the cause of economic growth.

In this study, the effect of horizontal and vertical diversification policies on economic growth in Iran is investigated. The approach applied is Markov Switching regimes, for annual data series 1979-2015. The growth rates of horizontal and vertical diversification, consume expenditure, and investment as well as inflation rate are the variables which are used in this study. The results show that inflation rate, consume expenditure and vertical diversification growth have positive and significant effect, in both 0 and1 regimes, on economic growth. Furthermore, the horizontal diversification and investment growth also have positive effect on economic growth but only in 0 regime. Additionally, the predicted economic growth rate under three proposed scenarios, for 2016 and 2017 years, show that we can reach 8 percentage as medium growth rate in the sixth development program with emphasizing on vacant capacity, especially horizontal and vertical diversification policies.

There are two major views on the subject of the relationship between the development of non-oil exports and economic growth. In first opinion, non-oil exports leads to economic growth through the increase in quality of inputs. In second opinion, economic growth will increase non-oil exports throughquantitative strengthening of inputs. In non-linear models there are the ability to calculate relationship between variables and causal variables in different regimes. For this reason non-linear causality models can have better results than linear causality models. For this purpose in this study a Markov Switching model is used to investigate non-linear causal relationship between economic growth and non-oil export in the years 1973-2013. The results indicate that in first regime (high growth) and second regime (low economic growth), there is no causality between exports and economic growth. The reason is lack of sufficient attention to production of other economic sectors during the oil boom. As a result, it causes the weakening of production, reduction of domestic production and international competitive power and finally reduction of the share of exports of goods and services in economic growth.

Although the trend of increase in energy consumption has made possible fast economic growth of industrial modern society, but because of combustion pollutants emission and increase in density of carbon dioxide in atmosphere has made irreversible changes in the world. Not only this trend is destroying finite and nonrenewable energies, but also it is releasing numerous of pollutants into the receptive environment (air, water, and soil). In this article, existence of causality relation between energy carriers' consumption with economic growth and carbon dioxide gas emission in sectors of Iran's economy (residential, general and commercial, industry, agriculture, and transportation) in period of 1997 to 2012 using causality Toda and Yamamoto method has been studied. In the agriculture sector, results show a unidirectional causality relation of energy carrier consumption to economic growth. In transportation, residential, general and economic sectors existence of bidirectional causality relation of economic growth variable and carbon dioxide gas emission with energy carriers has been verified. In industry sector, a unidirectional causality relation of economic growth to gas, electricity to economic growth and bidirectional causality relation of coal exist. Also, there is a unidirectional causality relation of carbon dioxide emission to oil and bidirectional causality relation carbon dioxide gas emission to other variables except oil exist.

The effect of saving on investment and economic growth is an important issue in both economic theory and policy. Also, having high and stable economic growth is of importance for all economies. On the other hand, inflation and its adverse effects (especially on economic growth) is one of the main economic problems in many developing countries. This study examines the relationship between the rate of saving and economic growth in developing countries with low and high inflation rates. In other words, since there have been high inflation rates in some developing countries including Iran, we examine the developments in the saving rates and economic growth and the effect of inflation on their relationship. The hypothesis we test is that higher inflation cause the effect of saving on economic growth to be lower. For this purpose, a sample of a panel data for 67 developing countries over the time period 1995-2014 is used. Our empirical results imply that higher inflation has a negative significant effect on the relationship between the rate of saving and economic growth. In effect, our main finding is that the effect of the rate of saving on the economic growth is higher for developing countries with lower inflation rates.

Economic growth has always been an important objective of policy in different countries. In developing countries including Iran, to achieving a reasonable rate of economic growth is essential. Since developing countries are facing with low efficiency of investment due to technological backwardness, so this set of countries would be taking advantage from foreign direct investment (FDI) as a source of capital accumulation and promote economic growth. Iran has a good potential for utilization of this resource considering to entering the field of FDI after the implementation of the nuclear deal. But the impact of FDI on economic growth needs required fields, including the host country's financial development. Therefore, in this study financial development as an important variable in the FDI inflow and economic growth is considered. The results for 10 developing Asian countries including Iran in the period 1996-2013 indicate that financial development has a determining effect on FDI inflow to the set of countries, but this is not enough and political stability is essential for FDI inflow. Also, the results indicate that although FDI has a positive and significant effect on economic growth in these set of countries, but financial development has a deterrent effect on economic growth of these countries due to the weak institutions and inefficiency in the allocation of funds.

The results show that there is a positive and significant relationship between economics growth and degradation of environment (environmental quality degradation), which means that an increase in environment degradation indicator increased the economic growth. This case is because of the rate of resource depletion begins to exceed the rate of resource regeneration and Pollution Haven Hypothesis in the studied countries. The results of Sargen and Arellano-bond autocorrelation test also respectively show, there is correlation between tools and component disruption and model does not have autocorrelation in the first order difference. Meanwhile results of Toda and Yamamoto Causality test show the existence of unilateral relationship from the Environment Degradation indicator to Economic Growth.

This paper investigates the threshold effects of income inequality on economic growth in developing countries for the period of 2000 to 2012, using Panel Smooth Transition Regression (PSTR) model. The linearity test results indicate strongly nonlinear relationship among variables under consideration. Moreover, considering one transition function and one threshold parameter, as a two regime model, is sufficient to specification of nonlinear relationship among variables.The results indicate thatthreshold value for developing countries is 0.43 and the estimated slopeparameter is 0.35. In the first regime the impact of income inequality is positive and in the second regime has a negative impact on economic growth. human capital in the both regimes has symmetric and consistent effect on economic growth. Other results indicate that population growth and trade openness had been asymmetric effect on economic growth in the both regimes.

Quality of government intervention in the economy or in other words the efficiency and effectiveness of government, has a close relation with the development.Because policy makers are often ineffective, inefficient bureaucracy will be created. The inefficiency of the government can be very dangerous for development and economic security and will lead to waste of resources, monopolism, mistrust of government, economic instability and inappropriate institutionalization. This research examines the empirical relationship between the efficiency and effectiveness of government and economic growth in the context of GMM model using combined data for 121 countries of the world in the period from 1996 to 2013 in two separate groups for developing as well as developed coutries. The results show the positive impact of the efficiency and effectiveness of government spending on economic growth.
