Abstract
The investigation of determinants in Gross National Saving behavior especially effect of corruption, is one of the important issues in macroeconomics literature.
For this purpose, we use the corruption perception index in dynamic panel data approach (Arellano and Bond Method). The Empirical results indicate that the corruption perception index (reduction of corruption) has positive and significant effect on the gross national saving. The main results of model estimation for two groups of oil and non-oil countries of MENA, shows that in oil countries the elasticity of gross national saving is more than of non-oil countries and reduction of corruption can be increase the national saving in oil countries.
Moreover the results of model estimation shows that the inflation rate has negative effect and real per capita income and terms of trade variables have positive and significant effects on the gross national of saving in these countries.

Abstract
The main objective of this paper is to investigate the impact of corruption on the military burden of developing countries during the 2000-2015 period. To achieve this goal, a general model of military expenditures , two indexes of corruption including corruption perceptions and control of corruption, Panel Co-integration analysis and two-stage system generalized method of moment estimator (SGMM), has been used. The results of the estimation of the research model show that the effect of corruption on the military burden of the studied countries is positive and significant. According to other results, civilian spending (as an opportunity cost of military spending) and democracy have had a negative and significant impact on the military burden of developing countries. . Population as a social variable has a positive and significant effect on the military burden of developing countries, which indicates that defense is a public good. Per capita income and lagged military expenditure also have a positive and significant effect on the military burden of the studied countries. The average military burden of the countries of the world has also had a positive and significant impact on the military burden of developing countries, which indicates a rivalry of arms.

Abstract
This study examines the relationship between per capita income and per capita dioxide emissions in the form of a new definition of the Environmental Kuznets Curve, to investigate how corruption influences the income level at the turning point of the relationship between per capita dioxide emissions and income, in developed and developing countries the period 1994-2013 through the use of a panel data model. Our results support the Environmental Kuznets Curve hypothesis for developed countries and existence of an U-shaped relation for developing countries. We find evidence that the higher the country's degree of corruption, the higher the per capita income at the turning point for developed countries and the lower the per capita income at the turning point for developing countries than when corruption is not accounted for. Also, the share of renewable energy in both groups of countries has a negative and significant effect on per capita dioxide emissions, but the positive effect of urbanization rate in developed countries is significant and in developing countries is not.

Abstract
In recent years, some research has focused on the importance of the origin of an oil shock for macroeconomic dynamics in both oil-exporting and importing countries. The existing literature lacks a proper open Stochastic Dynamic General Equilibrium (DSGE) framework to investigate the effect of the origins of oil shocks on macro variables in a two-country model consisting of an oil-exporting county and an oil-importing country. To this end, we develop and solve a new Keynesian DSGE model to show how the different oil shocks originating from oil supply or oil demand, might have diverse impacts on key macroeconomic variables in oil-exporting and importing counties. For the case study, we use data from Iran as an example of an oil-exporting country that trades with the rest of the world. Our DSGE model is estimated by using the Bayesian method for the period 1986:1-2017:4. The result shows that an oil shock originated from the shortage of oil supply (an exogenous decrease in Iran's oil production) decreases total production, non-oil trade, employment, inflation and consumption in this oil-exporting country. While a negative oil supply shock increases production costs and reduces production and consumption in Iran. However, an oil shock originated from an increase in the demand for oil raises output, non-oil trade, employment, consumption, and inflation in Iran as an oil-exporting country while a demand-side oil shock boosts production and increases inflation in this country.

Abstract
The main objective of this article is to investigate the effect of the tax burden and corruption perceptions index, as well as the interactive effect of these two variables on the total factors of productivity, using the panel data of 18 countries in the Middle East and North Africa region (MENA) during 2002 - 2020 and Pooled Mean Group (PMG) method. The results of the study showed that increasing the tax burden without the corruption perceptions index reduces the productivity of the production factors in both the short and long term, While the increase of the corruption perceptions index and the joint effects of the corruption perception index and the tax burden have a positive and significant effect on the productivity of all production factors. The positive interaction effect of the tax burden and the corruption perceptions index on the productivity of the total production factors indicates that the increase in the corruption perception index reduces the negative effect of the tax burden on the productivity of the total production factors. An increase of one unit of the tax burden has had a negative and significant impact of 0.027 and 0.019 units on the productivity of all production factors in the short and long term, respectively, While the increase of the corruption perception index and the interactive effects of the corruption perceptions index and the tax burden are 0.022, 0.041 a and in the long term, 0.048 and 0.069 units have had a positive and significant effect on it.
