In this article, we examine the role of environmental quality and economic growth in the determination of health expenditure in the Middle East and North Africa region (MENA) countries for the period 1995-2014 using Autoregressive Distributed Lag (ARDL) method to explore the estimating the impacts of economic growth and environmental quality on heath expenditure. The results show that health expenditure, income, CO 2 and PM 10 emissions are a cointegrated panel. While long-run elasticities show that income and CO 2 and PM 10 emissions have statistically significant positive effects on health expenditure. The results show that the income elasticity is inelastic, that health expenditure is not more sensitive to income and the adjustment to changes in income in MENA countries.

The Purpose. This research is to investigate the relationship between the variables of technological innovation, research and development costs, economic growth, sales and export of weapons and military costs in Iran for the years 2000 to 2017. Design/Methodology/Approach. In this study, we examine using Autoregressive Distributed Lag (ARDL) method to explore the estimating the impacts of technological innovation, research and development costs, economic growth, sales and export on military costs. Findings/Implications. The results of this study showed that the impact of technological innovation and research and development costs on military costs is negative in short-term and long-term. Although the effect that these two variables have on military spending in the short-term is very close, in long-term the effect that research and development costs have on military spending is far greater and more significant. Also, the impact of economic growth on Iran’s defense economy is much less than the variables of technological innovation and research and development costs. So that this effect will be less in long-term. But, the amount of arms sales and exports in the short-term has a positive effect on defense spending, but in long-term it becomes negative and increase in arms sales and exports can help Iran’s defense economy. Originality. The countries defense economy can always have positive effects on military and civilian research and development, scientific innovation and technological progress, in this condition that the country’s macroeconomics can spend military spending on research and development and support innovation and inventions. Eventually adopt arrangements that use the innovations of the defense industry in the civilian sector, which will lead to economic growth. This is the experience of many developed countries that have been able to use the technological advances and innovations of the military sector in the civilian sectors as well, and to cause the economic progress and development of their country.

The Purpose. This study is to investigate factors affecting the attraction of international tourists to Iran for the years 1983 to 2015. Design/Methodology/Approach. In this article, we examine using Autoregressive Distributed Lag (ARDL) method to explore the estimating the impacts of economic growth, hotel development, real exchange rate on tourism industry. Findings/Implications. The results of this study showed that the effect of all variables hotel development, merchandise trade, real exchange rate and real gross domestic product on international tourism In Iran, in the long-term and short-term positive and also bilateral relationship is between them. Also, the greatest impact on the increase in the number of tourists entering Iran is the real effective exchange rate and real GDP and a very important point that the results of this research show is that the development of hotels can increase both the short and long term of the number of international tourism to Iran, so in this regard, the development of the necessary technologies to increase this industry should be It will be on the agenda of the private and public sector of Iran. Originality. Given the increasing number of international tourists and the growing role of the tourism industry in the economies of the country, identification of effective factors in attracting international tourists is more than necessary. Governments and the private sector need to identify the factors affecting the tourism industry in order to develop, compete and survive in the tourism industry.

There are many factors affecting Foreign Direct Investment inflows into the countries. One of them is Special Economic Zones that encourage Foreign Direct Investment inflows and achieve remarkable results in the world. Special Economic Zones are defined in the United Nations Conference on Trade and Development as the regions where production, trade and storage are not limited to time and are exempt from customs and taxes. This study analyzed the relationship between the Foreign Direct Investment inflows of Turkey, the Foreign Direct Investment inflows of the World and the number of the Special Economic Zone types analyzed using the Autoregressive Distributed Lag Method from 1980 to 2019. The results show that Foreign Direct Investment inflows of the World have a positive and significant effect on Foreign Direct Investment inflows Turkey in the long term and the short term. Also, the number of total Special Economic Zone has a positive and significant on the 2
