هدف اصلی مطالعه حاضر ارزیابی تأثیر خصوصیسازی و فشار رقابتی بر قدرت بازار در بخش صنعت ایران است. برای تحقق این هدف ضمن استفاده از دادههای دروره زمانی 1381-1397صنایع کارخانهای مرکز آمار از رویکرد هال-راجر و روش تخمین پنل دیتا استفاده شد. نتایج تحقیق دلالت بر وجود قدرت انحصاری قابل توجه در بخش صنعت ایران دارد و علاوهبراین تجربه خصوصیسازی در ایران نه تنها موجب افزایش رقابت در بخش صنعت ایران نشده است بلکه بعد از خصوصیسازی، قدرت انحصاری در این بخش افزایش یافته است و به عبارت دیگر در صنایعی همچون تولید مواد و محصولات شیمیایی، دارو و فرآوردهای دارویی و شیمیایی، تولید محصولات کانی غیرفلزی و صنعت تولید فلزات اساسی انحصار خصوصی جایگزین انحصار دولتی شده است. با مقایسه اثر خصوصسازی در صنایع بزرگ و و در کل صنعت مشخص شد که خصوصیسازی در صنایع بزرگ به قدرت انحصاری بیشتری منجر شده است تا در کل بخش صنعت. نتایج همچنین بر قدرت بازار صحه میگذارد به این ترتیب که با افزایش تمرکز بازار، قدرت انحصاری در صنایع ایران افزایش مییابد.

In various studies, to evaluate and measure the poverty, based on the poverty line, the poor are divided into the poor and non-poor and based on the data of the poor households, different indeces of poverty are calculated. Since the rate of poverty varies, the effect of each poor individual on the society varies as well. In this study, the size of poverty in Iran is measured by Fuzzy Membership Function. In the current study, using the raw data, the household income of the Iranian Sensus Beauro, from 1385 to 1397 is calculated using the index of age poverty by Gini coefficient and Bonferonie standard, in classic and fuzzy modes of poverty size. The results show that using the fuzzy logic has a significant effect on poverty size so that in the classic mode, it is significantly less than that of the fuzzy mode. The results also suggest that in both the classic and the fuzzy ways, using the Bonferonie standard instead of Gini Coefficient causes the rise of poverty.

Although economic growth is affected by the growth of factors of production, governance and government size were also effective on economic growth. In this study, the impact of government size and governance on the economic growth of perspective document countries evaluated over the period 2006-2017. To meet this end, The World Bank database and data of perspective document countries were used. Moreover, the optimum size of the government evaluated based on the proposed Baro method. This article sought to estimate the effect of government size and governance by using panel data and the threshold nonlinear two-stage generalized method of moment. The findings indicated that the average optimal size of the government was 18.38% of the gross domestic product. Also, in countries with less government size, the growth of government expenditures had a positive effect on economic growth, while countries with a government size larger than optimal, government spending had a negative effect on economic growth. In addition, the results confirmed economic growth was affected by the governance of the state.

Regarding the importance of poverty as one of the important issues in the development economics literature, the present study addresses the factors affecting poverty by emphasizing the role of industrial development in the provinces of Iran, during the period from 2004 to 2015. The application of spatial models is desirable in regional science research based on regional sample data that has a spatial component. Therefore, in this research, spatial panel econometric models are used for model estimation. Foster, Greer and Thorbecke Index for poverty and the variables of industry's per capita value added, the depth of industrial activities (the ratio of industrial employment to the number of industrial workshops), the concentration index, and the relative regional advantage as indicators of industrial development, have been used along with the indicators of inequality and inflation in the research model. In the first scenario, the concentration index was used and in the second scenario, the relative regional advantage index was used. Findings of two research scenarios with spatial panel model indicate the positive effect of inequality, inflation and the concentration ratio on poverty as well as the negative impact of industry per capita value added, the depth of industrial activities and relative advantage based on employment on poverty. However, the regional relative advantage variables were not significant on the basis of added value, and industrial exports and human development index were not significant in the model. The results of spatial overflow effects indicate that poverty in the provinces is influenced by independent variables in neighboring provinces. It is suggested that industry sector policies be taken into account in order to increase the share of industry in domestic production.

Over the past two decades, significant changes have taken place in the banking market power in Iran economy. In addition, economic theories provide different forecasts on the impact of banking market power on firms’ investment. For this reason, the present study examines the impact of these changes on firms’ investment. For this purpose, using the data of Tehran Stock Exchange companies during the period of 2005 to 2016, the investment model was estimated based on Euler's equations and dynamic generalized method of moments. The results of model estimation with confirming the existence of financial friction in Iran economy showed that firms faced financial constraint on investment. In addition, by rejecting market power hypothesis and by confirming asymmetric information hypothesis, the results showed that the declining in banking market power led to an increase in firms' financial constraints. The results also suggest that the firm size has been affecting the firm financial constraints, and increasing in the banking market power has reduced the financial constraints of small firms more than large firms. The results of model estimation with regard to the effect of business cycles indicate that during the boom period, the positive effect of the banking market power on firms' financial constraints has decreased and this effect increases during the recession period.

Iran’s tax system includes many forms of tax incentives, like as regionally targeted tax incentives. According to direct tax act, article 132, that includes this kind of incentive, declared taxable income of manufacturing and mining activities in less developed regions are totally (100%) exempt from corporate income tax for ten years. The aim of this study is to estimate the impact of tax exemptions of article 132 on employment of Iran’s less developed counties for the period from 1996 to 2008. In the present paper, a two- stage method is used. In the first stage, a proper control group is selected for each treated county by using Synthetic Control Method (SCM) and Genetic algorithm, and the impact of tax incentives article 132 on employment in Iran’s less developed regions is estimated via Difference in Difference (DID) Method, in the second stage. Results indicate that tax exemptions in mentioned Article have no impact on employment of Iran’s less developed counties.

Increase in government spending can lead to increase in production, supply of public goods and services as well as utility. However, it should be noted that increasing the role of government in the economy will cause crowding out of the private sector and this will reduce the utility.
The present study is looking for Iran's optimal growth rate of government's spending using time series data in the years 1978-2014. via a dynamic optimal control theory approach and the maximum principle.
The results show that, the optimal growth rate of government’s expenditure is 7% and the main factors affecting this rate is the ratio of private and public sector investment. Therefore, the current growth rate of government’s spending is not optimal and the government needs to control the growth rate of spending especially current expenditure.

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.

In the history of human societies, Education Institution has been thought of a key factor in human life and development. In Iran, Both before and after Islam, Education and culture have been considered as fundamental tools for human life exaltation. In Islamic republic of Iran’s law, development of education and increasing social welfare are of particular interest. Many scholars believe that, one of the effective ways out of poverty is human capital development. The aim of this investigation is to assess the role of Education in Iranian households’ consumption behavior. To this end, the budget survey of Iranian statistical centre was used to calculate indices such as: share of education in Iranian households’ expenditure and income elasticity of education demand. The results of this study indicate that education is a necessary service. Another important finding is that education expenditure in urban areas is significantly more than rural areas
