Due to the performance of subsidies targeted, present study has been done to examine the effects of results of the implementation of this law on production activities. Social accounting matrix of 2001 was prepared and then general equilibrium model was developed. Gasoline and diesel have two prices, so two scenarios were simulated. The results of the two scenarios showed that, targeted subsidies of energy carriers, reduces product in production activities, increases price of commodities, and decreases households' consumption.

This study aims at exploring the relationship between energy consumption/efficiency and production growth in manufacturing agencies producing transportation vehicles in 1995-2009 using Granjer, Hsiao’s Granger, Toda-Yamamoto causality and DPD approach. The results of the model show that in these companies there is a one-tailed causal correlation between production value and energy consumption/efficiency and the given correlation is verified in both of the causal approaches. Similarly, the estimation of the model using DPD approach shows that there is a significant positive correlation between energy consumption and the value of the product in big factories producing transportation vehicles. The results also show that compared with an increase in the employment rate or energy consumption/efficiency, an increase in investment in these factories has a more significant effect on the value of the products in these agencies. This indicates that changes in production technology from labor or energy intensive to investment can lead to an increase in the value of products in agencies producing transportation vehicles in Iran.

The purposes of this paper are the investigation of convergence hypothesis for GDP per labor in the presence of spatial dependence, and estimation of the spatial spillover effects of economic growth among the 11 adjacent countries of Caspian Sea during 1990 to 2010. Hence, the spatial Solow model has been estimated in the framework of spatial dynamic panel data. The results indicate that conditional beta convergence hypothesis is true for the countries under investigation and every country with average speed of 26.2% moves in the balanced growth path towards its own steady state. Moreover, according to the spatial Durbin model, there is a positive spatial autocorrelation of per labor GDP among adjacent countries of Caspian Sea; if the weighted average of neighboring countries per capita labor GDP of a country increases one percent, average per capita income of the country's labor force will raise 0.75 percent. Deepening regional cooperation and the development of common markets in order to gain more economic benefits are the two important policy proposed in this study.

The aim of this paper is to analyze the effects of income inequality on economic growth in 28 provinces of Iran during 2000-2011 by using Geographically Weighted Regressions (GWR) and Dynamic Panel Data (DPD) models. This paper has tried to study the spatial heterogeneity among 28 provinces in Iran by using the Mont-Carlo and Inter-quartile tests. The results show that spatial heterogeneity exists for income inequality, human capital and logarithm of real per capita income. This paper is focused on geographic weighted model that contain spatial heterogeneity. The empirical results of GWR and DPD models have shown that income inequality has a negative effect on economic growth in Iran.

This paper studies impacts of monetary and fiscal shocks on macroeconomic variables in Iran. For this purpose, a dynamic stochastic general equilibrium approach is employed to sketch an appropriate model for Iranian economy. To calculate the required coefficients, data of the period 1961-2012 released by the Central Bank of Iran are gathered. In order to take in consideration the Iranian economic characteristics, oil revenues, sticky prices, monetary policy, fiscal policy, and technology are considered in the model. Results indicate that technological shocks increase non oil production, private investment consumption, and GDP. So, technological shocks increase economic growth and reduce inflation. Increase in oil revenues promotes non-oil production, private consumption, government expenditure, and private investment. So, in short run, the impact of oil shock on economic growth is positive. But oil shock increases inflation via an increase in money base. Monetary shocks (increase in money base) increase internal consumption and money liquidity (the inflation) and somehow the GDP. But, monetary shocks have small effects on the non oil production. In sum, monetary shock has a small positive impact on economic growth. So, in short run, money neutrality hypothesis cannot be retained. Also, government expenditure shock increases government expenditures, private consumption, and decreases private investment. In sum, government expenditure shock has a positive effect on production, inflation and economic growth.

The main purpose of this study is to examine the relationship between market structure and economic growth in iran. Using Lopez - Azzam (2002) Approach, the extent of endogenous markup in different markets was estimated. Then the relationship between markup and economic growth was investigated by baranova (2013) model. In this paper we also examined structural and behavioral aspects of 131, 4-digit industry over the 1995-2011 periods. These aspects include markt power as structural variable and conjectural variation as behavioral variable. In addition we sought to identify the impacts of markup on economic growth. The results of this study indicate that based on conjectural variation, firms cooperate in 91 percent of industries. On the other hand, Lerner index and markup in 94.2 percent of industries were higher than 0.1 percent and 1.001 respectively. Our findingsalso indicate that there is a negative association between endogenous markup and economic growth. According to the results of this study, low level of competition in industries led to limited growth in Iran.

Infrastructures are one of the most important tools for transferring technology from developed countries to developing ones. These infrastructures will also increase the economic activities; decrease the production and transportation costs, and finally increase the efficiency. Thus, they can affect the economic growth. This study investigates the direct and indirect effects of education and health, and economic infrastructures on the economic growth of Iran from 1980 to 2011. To that end, an equation system was designed which uses 2SLS. The findings showed that one percent increase in the education and health infrastructures will increase GDP by 0.06, and increase the foreign direct investment by 0.03. The indirect effect of improving education and health infrastructures on economic growth via foreign investment is 0.06 while export can bring about a 0.02 increase in economic growth.
