This research was conducted using the meta-analysis method with the aim of synthesizing existing research on the relationship between identity Styles and academic performance. The statistical population of the study included all relevant studies conducted in Iran from 1385-1400 and available in the databases of Jahad Daneshgahi, Nurmagz, and Magiran. After evaluating the criteria for entrances and layaway requirements research, the correlation effects of the research were analyzed by CMA software. Also, two models of random effect and fixed effect were calculated. According to the results of the heterogeneous analysis, the randomized model was selected through Q and squared I indices. The findings revealed that the size of the combined effect of the investigated research after the removal of 4 effects size was 0.107. The combined effect size of the research was calculated based on the mean Cohen’s index. The results of heterogeneous analysis revealed of the existence moderating variables in the research as well. The results of this meta-analysis of theoretical and empirical foundations are indicative of the relationship between identity style and academic performance variables. Given the results of this meta-analysis, it can be concluded that for academic performance to be successful, it is essential to address the identity style among university and school students.

This paper investigates direct impacts of economic sanctions on Iran’ s economic growth from 1978 (Islamic revolution) till 2010. Data variables، apart from sanctions have considered from 1966 till 2010. Analysis method includes econometric method of vector autoregressive distributed lags (ARDL). Findings show that before extensive oil and banking sanctions against country in last two years (2013-2014)، sanctions did not have a direct and significant influence on GDP growth per worker in Iran (without considering oil).

Unemployment is one of the major problems of economy in different countries for example Iran and the requirement for solving this problem is identifying the factors effecting it. In this research the effect of economic variables like rate of economic growth, economic discrimination and the ratio of the capital holding to the labor force and population variables like immigration and the ratio of the rate of partnership of men to the rate of partnership of women on the rate of unemployment in the provinces of Iran have been evaluated. The given in this research are for the time period from 2005 to 2013 and the research model has been obtained by the method of panel data from the basis of which the effects of variables on the rate of unemployment has been clarified. Among the variables entered in the model, the index of interregional economic discrimination, using different variables for example the current budget and capital of the provinces, area, population, lack of education, unemployed, added value and hope for life have been calculated and it was its rational results which the effect of economic discrimination on the rate of unemployment of provinces, in the level of common confidence, is not confidential (it is 85%).

Economic growth and development and the factors affecting it have always been the main goals of economic policy makers. Early growth theories based on the two factors؛ capital and labor, could not explain clearly the difference between the level of per capita income and the rate of economic growth of countries. As a result, new theories have emerged and by relying on knowledge-based economics and measuring the amount of knowledge used in a country's products, indicators such as the index of economic complexity have achieved good results in this field. The purpose of this paper is, explain the role of economic complexity index along with other traditional growth variables in the economic growth of 13 MENAT selected countries in the years 2008-2017, using panel data and using the Generalized Movement Model (GMM). The software is Stata 16. Based on the results, the variables: government size, per physical capital formation and volume of trade with negative coefficients-16. 16,-0. 06 and0. 33, respectively, have a negative impact on the economic growth and human capital and economic complexity index with coefficients 0. 12 and 0. 074 have positive and significant impact on the economic growth of the studied countries. Therefore, increasing investment in training innovative and creative labor, expanding economic complexity and indicators can bring higher economic growth to the region. The low coefficient of economic complexity index in these countries indicates the lack of attention of these countries to the production of high-tech products.

More than 113 years have passed since the gradual formation of "oil-gas Iran" since the drilling rig in the number one well of Masjed-e-Soliman reached oil on May 25, 1908. The fact is that during this period, on the one hand, the wealth and income of natural oil and gas resources were not necessarily "fairly" distributed among all Iranians who are the main owners of these resources; on the contrary, in many cases, they have been distributed among the influential groups in the form of unjust government rents, and on the other hand, these resources have not been used as they should be in the service of the country's economic growth. Given these two facts, the two main problems of this research are: 1) Based on which value theory can the wealth and income of oil and gas resources be more fairly distributed among all Iranians? 2) How can such a fairer distribution be used to achieve high and sustainable economic growth? The research method is that by examining the basic features of common support schemes and reviewing the value bases of such schemes in the form of several theories of justice and with the pathology of those schemes, the implementation of a basic income plan (UBI) which is financed mainly through wealth and revenue from oil and gas resources, defended as a fairer and more efficient plan than current support schemes. In the following, the different methods of financing this project and the mechanisms of its impact on economic growth are examined. Finally, it is argued that during a virtuous circle, on the one hand, a "universal basic income institution" in addition to eradicating poverty, can lead to high and sustainable economic growth, and on the other hand, how this economic growth can continuously increase the amount of UBI for the current generation and future generations.

Abstract Expanded   1- INTRODUCTION Developments and fluctuations in economic growth will cause significant changes in the economy and its variables. Therefore, examination of the cause of fluctuations and instability in economic growth can eliminate or improve their impact. During the last 4 decades, economic adjustment policies - which have been proposed by the international community to various countries with the aim of stablization of the economy in the short run and changing the structures of the economy in the long run - have been implemented in Iran. This study was conducted to investigate the compatibility of economic adjustment policies in Iran.   2-THEORETICAL FRAMEWORK Economic growth of a country is the change in production of a country compared to the previous year. Therefore, a change in any of the components of a country's GDP causes a change in economic growth and, consequently, causes fluctuation or instability in it. Oil revenues as one of the most important export revenues from natural resources, depending on the type of use (in current consumption or investment) affect economic growth or instability. On the one hand, oil wealth can accelerate the pace of development due to the level of financial development and increase national income, on the other hand, long-term economic growth will be damaged due to imbalances in different sectors of the economy. Financial liberalization on the one hand, citing neoclassical theories and the free flow of capital from high-capital economies to low-capital economies, life cycle models and increasing private savings and attracting investment in the portfolio, increases project returns. on the other hand, some countries were affected by the implementation of financial liberalization and faced severe financial crises, followed by economic instability. Trade liberalization due to the transfer of knowledge and technology to a country can improve economic growth. Trade also allows producers to access larger markets. Improved productivity through the use of untapped resources, more distinctive products with higher quality and lower prices, and ultimately increased production and surplus consumer welfare. Despite the positive effects of trade liberalization, this policy will destabilize economic growth in developing countries that have few products to offer to the world market. Privatization is a fundamental structural change of ownership, which is transferred from the public sector to the private sector, and this change of ownership leads to fundamental changes in the basic incentives and motivations of owners and managers of enterprises and the goals of those enterprises. the effect of privatization on economic growth can be demonstrated through microeconomics theories, the theory of new institutional economics, the theory of public choice and the theory of representation. In the empirical literature, the importance of the role of government is how it can provide a stable environment for economic growth. Examination of the issue of government spending (as an indicator of its size) and GDP growth, there are conflicting results, and the relationship between government spending and economic growth depends on the sources of financing government spending and government performance. Thus, if government spending is financed through borrowing, the relationship between government spending and economic growth is negative, and if government spending is financed through taxes, the relationship between government spending and economic growth is positive.   3- METHODOLOGY In this study by using the vector auto regressive model (VAR), the relationship between economic adjustment policies on fluctuations and instability of economic growth during the period 1981 to 2019 has been investigated. the annual fluctuations of economic growth were selected by using the exponential conditional variance (EGARCH) model with intervals 1 and 2 to show the variance inequality and the effects of the three policies of privatization, trade liberalization and financial liberalization were measured. The variables of trade intensity, volume of assets transferred to the private sector and the amount of foreign assets of the banking system are considered as indicators of trade liberalization, privatization and financial liberalization policies, respectively.   4- DISCUSSION Out results showed that the variables of financial liberalization have the lowest (0.6%) and the variables of commercial liberalization have the highest (21%) share in the volatile changes of economic growth. Also, financial liberalization only increases in the short run and does not affect instability in the long run. The trade liberalization variable will reduce economic instability, while the surge in oil revenues will increase instability in economic growth. The government expenditure variable in this study has a dual behavior, so that in the short run will reduce instability and in the long run will increase the instability of economic growth. Privatization policies have the most short-term (0.0173) and long-term (0.0052) effects on economic growth instability and will increase economic growth instability.   5- CONCLUSION & SUGGESTIONS Examination of the results of the instability response to various variables shows that not only economic adjustment policies incompatible in terms of their impact on growth fluctuations, but also not compatible with government policies. In the short and long term, privatization and financial liberalization policies will increase and trade liberalization policies will reduce instability. While the government's fiscal expansion policy (increase spending) will reduce instability in the short run and increase economic growth instability in the long run. Thus, the simultaneous implementation of trade liberalization policies and increased government spending (financial expansion) will reduce instability in the short and long term. Because both policies are compatible with each other and their results in the short-term and long-term will reduce the instability of economic growth. Therefore, it is recommended to adopt trade protection policies (both in terms of imports and exports) because these policies will not only improve the trade balance and increase the level of trade liberalization, but also the instability of economic growth. and will also reduce production.

Introduction: Higher education effects national economic growth and development in three perspective: 1-human capital formation 2-consumption 3-postive externality effect.Materials and Methods: Around the world there are many researches in developing countries about these effects on development and growth. This paper investigates the effects of higher education curricula and academic disciplines on the labor force and thus on economic growth and growth of value added of economic sectors (industrial, agricultural and service) in Iran over the 1978-2007 periods. In order to survey above material we used an economic growth model, and estimated it with econometric methods.Results: Results reveal that higher education overall provided a positive and significant effect on Iran's economic development and that engineering and agricultural science played the most prominent role in this process. Conclusion: In order to get higher economic growth, allocation of resource to higher education specially engineering group is important.
