The present study examine the impact of export diversity on income distribution. This study investigate the selected developing countries during 2013 to 2017. Export diversification index is used for measuring export diversity and gini coefficient is used for measuring income distribution. The model is estimated in panel data framework using feasible generalized least squares method. The results of the present study show that with increasing export diversity, gini coefficient decreases and income distribution improves. Also, per capita income, human capital, foreign direct investment and trade openness have a negative and significant effect on gini coefficient and the effect of industrialization on g gini coefficient is insignificant. According to the results, developing countries can improve income distribution by moving towards export diversification.

Development of human resource motivation and productivity improvement is the fulcrum of this system. For comprehensive quality management, sub-systems should be created in the organization. As a starting point, 5S alone can exchange knowledge and experiences of each individual by involving employees in the form of working groups. In this way, repeating this process, put people on the path of creating motivation and the spirit of all-round teamwork. The grooming system is a military system for organizing the work environment, it is a system that, by attracting the participation of employees, creates an orderly environment at all levels of the organization. This research aims to investigate the effective factors on productivity with the operational implementation of the grooming system in the repair and reconstruction environment of logistics Deputy and FARAJA logistic police.

According to the number of changes and improvements in operation at the level of environmental repairs, it is implemented with the panel data3 method. The science of econometrics is based on data mining, cross-sectional data, and time series with 90 real observations before and after the implementation of the project using the Persian model and calculation and measurement software.

Fitting the regression line using Hausman tests4 and collinearity tests, the impact of each change has been identified, which is extracted from the forms during work (forms of the stages of the grooming system) that In terms of reliability and the questionnaires were confirmed, it was obtained. These changes include changes in decoration, separation, visual management, education, lighting, grooming and ventilation, color management as a change in the seventh total of change, and the amount of productivity as energy dependent on the result that all independent changes lead to this result. arrive have a positive effect on productivity, Then by using the model designed on these characteristics on the evaluation variables and calculating the impact of these changes, respectively, for the first change, 0.02 for the second variable, 0.04 for the third change, 0.08 for the fourth change, 0.2 for the fifth to seventh change, with less effectiveness than The rest was calculated. Then the effect of the implementation of the maintenance system with new changes was calculated and finally, the improved productivity of the FARAJA Repair and Renovation Center resulted in a 25% increase. The implementation of the grooming system led to important results such as: reducing rework costs, reducing waste, increasing useful working time, increasing useful working hours, reducing the cost of repurchasing items, and reducing risks due to non-compliance with health principles. Workplace safety occurred alongside improved productivity.

Non-oil export development is one of the policy priorities in countries dependent on oil exports to achieve balanced and comprehensive development. However, the development of non-oil exports depends on the growth of the private sector and the growth of the private sector is also possible through both the transfer of assets and public corporations to the private sector (privatization) and the removal of barriers to private sector activity (improving the business environment). But, empirical evidence has shown that privatization does not result without improving the business environment. Hence, economists emphasize that improving the business environment is prior to privatization. In this regard, the present study has tried to determine the impact of Business space on market share of non-oil export in developing selected countries during the period 2008-2019. From the three indicators, Documents to export, Time to export and the Cost to export were used as an alternative to the business environment. Eventually, the research model using panel data and the generalized method of moments estimated and results showed that the impact of Documents to export, Time to export and the Cost to export Documents to export, Time to export and the Cost to export on market share of non-oil export is negative and meaningful. Also, the effect of controlling variables including per capita production, real exchange rate and openness on market share of non-oil exports is positive and significant

Today, the importance of developing and improving the business environment as a prerequisite for the development of entrepreneurship and the achievement of favourable economic growth is to a large extent considered in the world's economic space as infrastructure and economic strategy.

Considering the development of individual and institutional entrepreneurship indices can help to better understand business opportunities in the field of medical equipment and to gain competitive advantage and increase the share of countries through the production of new, high quality and low cost products. Worldwide export of medical equipment, Current research, with using dynamic Pane Data approach and generalized moment method, the effect of individual and institutional indicators of entrepreneurship on the market share of 20 countries selected from global exports of medical equipment during the period 2013-2017 was investigated. The results of the model estimation showed that the effect of individual and institutional indicators of entrepreneurship on the market share of selected countries from global exports of medical equipment is positive and significant. Also, the effect of control variables of degree of openness of economy and real exchange rate on the market share of selected countries from global exports of medical equipment is positive and significant.

Scrutiny of energy consumption behavioural patterns in various economic sectors represent an essential step in energy consumption planning and management. Delineation of determinants of energy demand is highly significant in Iran which is a country with rich energy resources, abundant oil and gas supplies, heavy minerals and potential resources. Therefore, using Panel Data Methods, this study explored the effects of urbanization and human capital on energy consumption in Iranian agriculture, industry and services sectors over a 17-year period between 1996 and 2016. The results showed that human capital, workforce productivity, interactive effect of human capital on workforce productivity and the squared value of economic sectors had negative effects while the added value had positive impacts on energy consumption during the specified period. The results of the analyses indicated that human capital and workforce productivity in economic sectors had negative significant interactive effects on energy consumption at the critical value of .01 implying that an increase in human capital and corresponding workforce enhancement will facilitate economizing on energy consumption. Moreover, the estimated coefficients of added value and squared added value of economic activities revealed an inverse U-shaped relationship between added values of economic sectors and energy consumption.

Tourism is known as an important source of international currency exchange that can provide funding for economic growth in the countries. Tourism revenues are an example of alternative exports, which can improve balance of payments, increase employment and finally economic growth. In this regard, this study reviews the causality relationship between the tourism receipts and expenditure with economic growth in the countries of the Middle East and North Africa (MENA) during 1995-2015 using the panel data approach. So, in this study a new approach to hypothesis of tourism leads to growth is proposed and the causal relationships between tourism and economic growth are classified in four hypotheses growth, conservation, feedback and impartiality. This new classification leads to explain the different causal relationship between tourism and economic growth for each country specially. The obtained results shows that despite of the relationship bilateral causality between tourism and economic growth (confirmation of feedback hypothesis) for a set of countries, for each of countries, the causality orientation between tourism and economic growth, depending on the country's situation and the tourism indicator used is different. Also it shows that, there is a positive relationship between tourism receipts and expenditures with economic growth in the countries under study

One of the most important economic policy goals in Iran is the fair and equitable income distribution among classes of people as well as different areas, and in this regard, the channels and many factors can be effective in the income distribution and its improvement. Based on available economic fundamentals, one of strategies to improve the distribution of income is tourism development. Therefore, in this study, there has been investigated the role and effects of tourism development on income distribution in the provinces of Iran during of period 2005-2015 using panel data method. Based on the results of this study, urbanization rate, human development index, increasing passengers and the increasing proportion of truism credit to provincial credit have a positive impact on income distribution. Also, studying the value added indicates that tourism development in the province provides evidence of Kuznets hypotheses confirmation.

In the most countries, particularly developing countries which have undeveloped financial markets, banks play a key role as the most important financial intermediary. Improving the performance of banks can have significant impact on the efficient allocation of financial resources. Bank's performance is affected by internal factors under the control of banks and external factors. Economic freedom can affect the quality of bank's performance through the impact on the environment of exchanges. This paper examines the impact of the internal variables such as bank's liquidity, size, credit risk, non-interest expense to assets and capital ratio and key macroeconomic variables including economic growth, inflation, and economic freedom index on the bank's performance in Iran using panel data model over the period 2005-2012. The results show that the economic freedom and freedom from government intervention indices have negative effect and economic growth rate, inflation rate, bank's capital, business freedom, monetary freedom and freedom from corruption have positive effect on bank's performance in Iran.

Export insurance facilitates export and global economic growth by decreasing and compensating commercial, political and economic risks. There are different opinions about the effect of export insurance on export. Despite this and since export insurance increases the cost of exports, a significant effect of export insurance on export deserves further investigation. The present research examines the hypothesis which is export insurance has a significant and positive effect on exports. For this, an econometric panel data of 40 countries (including 20 developed and 20 developing countries) during the period 2005-2013 has been employed. The results from the model confirms a significant and positive relation between export insurance and exports. Therefore, we suggest that policy makers and exporters pay special attention to export insurance.

Many models have tried to identify the factors influencing on brain drain and the impact of these factors explains. In this among some of economists believe abundance of natural resources been exacerbated rent-seeking behaviors in economics, disruption in the allocation of resources, increasing social and economic inequality, weakness of government management of the use of these resources to develop human capital demand cause exacerbate the brain drain in countries with abundant natural resources.While management improvement abundance of natural resources of channel governance is raised as the a factor attraction that can reduction exit many of the elite of countries aforementioned. According to the important role management improvement abundance of natural resources of channel governance on brain drain, leading research-findings using the Generalized Method of Moments (GMM) is paid to check impact of management improvement abundance of natural resources of channel governance on brain drain from the selected oil exporting and developed countries to United States during the period 1996-2014. The results suggest that management improvement abundance of natural resources of channel governance has significant negative relationship on brain drain in both oil and developed countries being studied choice. Also findings of the econometric study, has Approved significant negative relationship welfare gap index and real wage gap with brain drain in both groups of countries studied. Human capital variables has positive and significant relationship in developed countries and positive relationship and meaningless in selected oil exporting on brain drain
