The important role of export in economic growth and development and its impact on different economic sectors constitute a broad and significant issue upon which a large number of economists have been concentrating their minds, and has even branched out extensively into other scientific fields. In this regard, developing countries benefit from potential endowments due to relative advantages and huge amount of resources and have expertise in raw materials production and international specialization has led these countries to be dependent on raw materials export earnings. Likewise, considering that export's commodity prices are unpredictable, their fluctuations lead to export earnings be violated. Consequently, the economy as a whole would negatively or positively be affected and these result in instability of economic growth. For this purpose, this study aims at investigation of relationship between export earnings' volatilities and economic growth. Therefore, using estimation of St. Louis growth model over period 1976-2010, and Auto-Regression Distributed Lags (ARDL), effects of export earnings' volatilities on economic growth was evaluated. The findings of this study indicate significant negative impact of export earnings' volatilities on economic growth.

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.

Prices as the most fundamental variable in the housing sector have the task of optimizing the allocation of economic resources. Statistics show that during the period under the study (1991-2011), housing sector in Iran has experienced four jumps in prices. In this paper, we build a Dynamic Stochastic General Equilibrium (DSGE) model to study the fluctuations in prices and output of housing sector and identify the effects of monetary and oil price shocks on this fluctuations. The impulse response functions show that higher money growth rate temporary increases output and inflation in the both housing and nonhousing sectors. In addition, due to the higher elasticity of supply in the nonhousing sector, the effects of monetary shock on production in this sector are more than the housing sector. Higher oil revenues through increased liquidity and then increasing demand of private sector causes higher inflation in the economy. The results show that a shock in oil revenue temporary increases production and inflation in the housing and nonhousing sector simultanously. The difference is that the inflationary effect of this shock is higher than its effect on the production. Altogether, the comparison of the moments of the model and its impulse response functions with that of real world shows that our model can well illustrate the cyclical fluctuations of most important variables in the housing and nonhousing sectors.

This research provides a comprehensive composite indicator to evaluation human development based on Islamic civilization’s teachings. According to analysis of theoretical framework of Islamic civilization’s teachings, human development in this research includes “economic-welfare”, “social-cultural”, “religious-ethical”, “political-governmental” and “scientific-educational” dimensions which are derived from the extension of Islamic teachings in the field of human life. Final composite indicator of this research will be derived from a seven-step method and findings of that indicator show that scientific-educational dimension and public health component are the most important strengths of I.R. Iran in which if these elements have more weight in final composite indicator, situation of I.R. Iran will be 10 steps higher than current situation. But the economic-welfare dimension (except infrastructure capitals) and the efficiency of governmental organizations and legislative institutions are the most important weaknesses of I.R. Iran and improvement of business environmental, macroeconomics indicators, professional legislation and stability of laws and regulations and increment of efficiency of executive organizations could have important effect on situation of I.R. Iran.

Considering statistical data during 1981-2007 in Iran’s economy shows some co-movements between per capita wage and productivity indices, but does not explain which one can explain productivity improvements. Whether productivity increase is the result of wage increase, or its increase have caused wage increase, or we can not explain their relationship in causal relationship. Since productivity increase is very important in developing economies, we reviewd related literature, and finally we used Gewek’s econometric model for comparing traditional and modern theories for industrial sector of Iran’s economy, to see which theory is more applicable. Results indicate both wage productivity theories are statistically significant in industrial sector of Iran’s economy, but modern wage-productivity theory is more applicable when compared with traditional one.

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.

Growth of financial economics literature in recent decades has clearly shown that financial development facilitates economic growth. Important question is that why some countries have more developed financial sectors than others. In this study, effect of government size and good governance on financial development was considered by using statistical data, including 76 developing and developed countries in time period of 1996 to 2011. The relationship between the variables was estimated with Generalized Moment Method (GMM). The results showed that government size and good governance has negative and positive effects on financial sector development, respectively. Also, for the purpose of adapting and improving of the results, effect of government size and good governance on financial sector development was separately examined in developing and developed countries, which supported the previous results. The results confirmed the political view and the analysis of results also demonstrated that inflation has the highest influence on financial sector development in developing countries.

The shadow economy is a real phenomenon with significant and complex concepts that requires deep study and attention. For all the countries of the worldespecially developing countries which possess a more expanded volume of these activities, always there are concerns about the growing tendency of shadow economy. Due to the hidden nature of the shadow economy and its unregistration, official statistics don’t reveal the exact status of the governmental economy and since these statistics are applied to policy- making, inexact figures and information can lead to inappropriate political responses. In the present paper, the aim is to investigate the effect of unemployment rate on the shadow economy in 67 developing countries in period of 1999-2009. The paper’s data analysis is System Generalized Method of Moments (System GMM) approach. By and large, the results of this approach show that in the countries under study the unemployment rate has a positive effect on the shadow economy.

The main aim of this research is investigating the relationship between unemployment and job vacancies and also the relationship between the number of job seekers and job vacancies in provinces of Iran. In other words, this paper seeks to obtain the Beveridge curve and Matching Function in provinces of Iran. Beveridge curve is an equilibrium relationship which equates unemployment input and output flows. Matching Function describes the equilibrium in the labor market and then shows the normal state of the country in the long run. Using panel data, this study has been done in 30 provinces of the country, in the years 2007 to 2011. The results of the Matching Function have shown positive and significant relationship between job vacancies and job matching. Beveridge curve evaluation results are also consistent with theoretical foundations and have proven negative and significant relationship between unemployment rate and job vacancies. Job vacancies squared positive coefficient indicates convexity of Beveridge curve.

In the VAT Acts in order to control gasoline consumption as one of the environment- polluting and also to earn revenue resources for environment protection, higher tax rate than the standard rate is levied on its consumption. In this paper, forecasting income receivable from the tax base using the two-stage approach has been considered. In the first stage, tax base (gasoline consumption expenditure) has been forecasted in the period 2013 to 2016 and then gasoline consumption tax, using multiplying the tax rates in gasoline consumption expenditure predicted, has been calculated for the mentioned period. In this regard, for precise prediction of the tax revenue, supervised neural networks method and for networks training, error back-propagation algorithm are used. The results indicate that during the mentioned period gasoline price changes (as the most effective variable) arising from VAT will have no serious impact on gasoline consumption. Also, VAT revenue of gasoline consumption will increase by an average annual rate of 35 %.

Investigating the effect of government corruption and financial liberalization on economic growth is a fundamental issue in recent economic literature. However, considering these two phenomena simultaneously have been ignored by researchers. This paper, empirically and theoretically, studies how negative effect of corruption can be affected by financial liberalization. The results show that, by liberalizing financial account, high corrupt countries levy more taxes and therefore the negative effect of corruption on economic growth intensified. In empirical model, we include OPEC countries for the duration of 1990-2013. Estimation results by GMM method show that the negative signs of the interaction between financial liberalization and corruption imply that the partial impact of financial openness on economic growth decreases as the degree of corruption increases.

In many countries, achieving to the millennium development goals, such as sustainable economic growth, poverty reduction and human development enhancement are their important priorities. One of these goals is to improve the human development index that is used to compare the level of welfare. This study, using the annual data of selected MENA countries from 2000-2012 and by applying Dynamic Panel Data and GMM estimators, wants to determine the factors that affect on human development. For this purpose, trade variable (percapita import, percapita export and per capita trade) has been used in three separated models. The results of the model with n-step GMM estimator of Arellano and Bond (1991) indicate that in all models, trade has positive and significant impact on human development. If percapita import, export and trade are considered as explanatory variables in the model, the increase of $ 10,000 in these variables, will increase human development index by 0.029, 0.024, and 0.025 respectively. Based on the results, educational expenditures, per capita health expenditure and foreign direct investment have also positive and significant effects on human development.

The 2007 global financial crisis showed that financial cycles is one of the reasons for the fluctuations of macroeconomics and could create business cycles. If there is such a relationship, adopting an active policy response to smooth financial cycles seems necessary. The present study investigates the dynamics of the relationship between financial cycles with business cycles and the inflation gap in Iran's economy during 1990:1 – 2016:4. To accomplish this, first, a financial condition index for Iran's economy has been created. In addition, the causality test has been conducted in the frequency domain and available frequencies have been determined to predict economic growth whit the index. Then, in order to investigate the purpose of the research and analysis in the frequency domain and time-frequency domain, the new Maximal Overlap Discrete Wavelet Transform and Continuous Wavelet Transform tools are used. The results show the relationship between financial cycle and the business cycle in the short run and long run is bilateral and extremely unstable. In the medium run, the business cycle is a leading variable, but the phase difference between the two variables in the 1990s is different from those of the 2000s. In the medium run, the financial cycles have kept inflation away from its long run trend. But in the long run and after 2007, this relationship has been reversed. According to the results of the research, it is recommended that monetary policy makers, in addition to smoothing output and inflation around their long run trends, should also consider this for the financial sector so that the two objectives above can be achieved with lower error in different frequencies.

According to the new growth theories, human capital is considered as one of the main variables affecting growth and development. Therefore, with providing and creation of appropriate context for it, we will see an increase in the production and development of GDP. Human development index can have a significant contribution to economic development with considering the fundamental factors such as health, education and labor income that have been mentioned as parts of growth software in some text. The aim of this paper is to investigate the effect of human development index on Iranian GDP over the period of 1971-2011. This study aims to answer the question that what is the equilibrium relationship (long run and short run) within these variables. To do so, firstly the effects of human development index on the GDP were tested by using ARDL. Then, to determine the exact effects, the impact of components of human development index on GDP were tested. The results showed that in the short-run human development effect on GDP was small and insignificant. But, this effect is stronger in the long run. The second model results showed that the impact of each component of human development in the long run is stronger in comparison to the short run.

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.

Regarding the important role of health in economic growth and development, the purpose of the present paper is to investigate the impact of life expectancy, as the most important indicator of health, on economic growth in Iran during 1965-2009. The estimated Smooth Transition Regression (STR) model supports a nonlinear threshold behavior in the relationship between life expectancy and economic growth in the country in a two regime structures with a threshold level of 55.34 years. In other words, our findings are both consistent with Acemoglu and Johnson (2007) for the negative impact and with demographic transition theory for the reducing effect of life expectancy on economic growth in Iran. This shows the country is approaching the stage of the fertility transition, where the increase in life expectancy will bring about a decline in population.

In recent years, the financial condition index (FCI) has been used in many countries as an important index to determine the state of macroeconomic policies. For this purpose, in the present study, the effects of financial condition index on macroeconomic variables were investigated by applying the time-varying parameter factor-augmented vector autoregressive model (TVP-FAVAR) and using quarterly data during the period (1991-2019). The results indicate that the response type and response rate of macroeconomic variables were different due to the financial condition index shock over time, and this indicates the necessity of employing the parameter - variable approach. According to the obtained results , The unemployment rate and economic growth rate variables in the short and long term showed a Negative and positive response to behavioral changes in the financial condition index variable, respectively; The effects of the financial Conditions Index shock on the inflation rate variable appear after one period; However, the response of this variable to the financial condition index shock in the short and long term has been different according to the conditions prevailing on the economy of the country . Also, the financial conditions index shock in the short run has improved the Gini coefficient variable, but in the long run, especially in the late 2010s has rised the income gap. The response of the budget deficit variable to the financial condition index shock in the whole period under review was positive and the financial condition index shock has increased the government budget deficit.

Considering the importance of discussing the effect of government debt size on economic growth, this study examines the validity of the debt laffer curve using a Smooth Transition Regression (STR) model in Iran during 1973-2016. The findings support a threshold behavior of two regimes between the government debt size and economic growth in the Iran's economy. The threshold level of government debt size is 41.70% of the GDP. In periods that the government debt size is less than 41.70 % or the first regime, government debt size has a negative effect on economic growth. Therefore, the evidence does not corroborate the existence of the Debt Laffer Curve in Iran's economy. The disapproval of this hypothesis and the negative impact of government debt on economic growth - at low levels of debt size - can be rooted in the fact that government spends the borrowed funds on the deficits that emerged from structural imperfection and institutional rigidity, while it should be used to develop infrastructures or foster productive investments.

Today in all countries one of the macroeconomic objectives is achieving an acceptable level of labor employment, for that must be regarded capacities and relative advantages for each of the economic sectors. Due to the importance and share of services sector of total employment and exchange rate volatility in recent years in Iran; the purpose of this study is to investigate the effect of real exchange rate uncertainty on employment for services sector in Iran from 1974 to 2012. The ARCH approach used for estimating real exchange rate uncertainty and ARDL model for employment pattern. According to research results, the real exchange rate uncertainty has a positive impact on employment in services sector in Iran; because the effect of real exchange rate uncertainty on employment in agricultural and industry sectors is negative. So the labor departed from agriculture and industry will transfer to services sector. Relationship between added value and per capita capital on employment in this sector is negative, that indicates labor and capital are replaced for each other in which capital replaced for labor in both short and long term. Import of services has positive effect and export of services has negative impact on employment in services sector.

This paper aims to study the non-linear and threshold effects of the macroeconomics variables on inflation in Iran's economy using the sequential seasonal periodic data from 1991 to 2018 based on the Soft Transition Regression (STR).In the developed model, the cash growth was selected as threshold variable with the approximate sum of 4.22 percent (17 percent a year) as the threshold limit. The results show that the linear approximation cannot satisfactorily explain the non-linear effects of the oil incomes and other variables in different regimes. In other words, the sequential non-linear pattern, having considered the regime changes and the changing indices during time, is better able to explain the inflation behavior in Iran’s economy in comparison with the linear pattern and can demonstrate the dynamics effects of the macro nominal and literal variables on inflation in Iran’s economy more comprehensively.The results show that, depending on the regime conditions, other macro variables such as current expenditures, construction expenditures and economic growth exacerbate inflation. Moreover, in high regime, the price level deviation from the long-term balanced relation, is a very significant factor in inflation acceleration, to such extent that inflation exorbitantly reacts to this gap. Gross domestic product and its hindrance have anti-inflammatory effects in most regimes.In different regimes the oil incomes have not had meaningful or significant effects on inflation, as it seems that the effect of this variable on inflation is controlled to a very great extent by other variables.According to the findings, it seems that cash growth is the most important factor of regime change in the relationship between inflation and other macro variables in the economy of Iran. The legislation authority, by controlling the cash growth and transferring it to the low growth regime, is able to abort or reduce the effect of many other variables such as current or construction expenditures.

The limitation of the production factors is always considered as one of the important issues in the production process. One of these factors is the workforce, which will provide different levels of work for wage change; so, according to Classic economics, increasing monetary rewards will lead to an increase in labor force effort. Recently, incentive reversal is introduced with the advent of group activities in organizations; this means that increasing the monetary rewards of individuals will reduce the efforts of some people. In addition, the ability of individuals to take collective action to identify and solve problems can be viewed from the point of view of social capital. In this regard, the main question of this study is to investigate the influence of social capital on cooperation within the group and an adjustment free rider effect in the framework of sequential game. Therefore, by providing a laboratory environment and the usage of 210 players, a three-member and two-stage team game was designed. Results show that there is a significant relationship between the level of social capital and the individual incentive reversal. In addition, increasing social capital reduces the level of incentive reversal in the third players.

Following the economic sanctions that have been imposed on Iran in the years after the Islamic Revolution, always economists were facing this question that; what is the effect of economic sanctions on different economic variables and how much is it? This study aims to analyze the effect of economic sanctions as dummy variable on economic growth in Iran, using Indexing and weighting (determining the importance) of various sanctions that historically imposed on Iran. For this purpose, using time series data and Auto Regressive Distributed Lag (ARDL) model, we analyze the effect of economic sanctions on economic growth from 1978 to 2013. Short-run estimation results show that in the short term weak sanctions had not significant effect on economic growth, but moderate and strong sanctions respectively with coefficients 0.0098 and 0.43, has had a negative effect on economic growth. Long-run estimation results show that in long term weak and strong sanctions had not significant impact on economic growth, but moderate sanctions with coefficient 0.024 has had a negative impact on economic growth. Finally error correction coefficient in model is - 0.407.
