روش تجزیه برداری اثرات ثابت

Some of the economists believe that current volume of international trade is less than the volume that has been predicted by the conventional trade theories. Unobserved barriers (i.e. Corruption) are one of the factors that can reduce the volume of trade from the amount that has been predicted by these conventional theories. This research has studied the role of corruption in the trade volume of selected countries in the Middle East and Latin America. In this study we have used an augmented gravity model of trade and panel data. In addition for estimating the model, we have used fixed effects vector decomposition method. The results showed that the trade is inverted-U shape function of corruption and the little amount of corruption in both regions initially helps the amount of trade to increase but when it reaches the threshold, the volume of the trade reduces in the studied countries. In addition, the results indicated that the existence of corruption in the importing country has a negative effect on the trade volume of the studied countries and it can reduce the amount of the bilateral trade.   JEL classification:F10, F19, P37, C23
