Abstract
ABSTRACT Several advanced and developing agricultural countries seek to introduce aids and supports to the agricultural sector; particularly, agricultural exports such as grain crops. Despite of the conventions prevailed during the few past decades which were calling to reduce support for agricultural products; most of the main grain producing countries are still backing up this sector in many means which have been confirmed by standard analysis. Despite the fact, it may contradict the freedom of commerce, which is being called by advanced counties in terms of modern economic theory. The study has concluded that though the international resolutions that are calling various main grain exporting countries to reduce support along various periods of time until be abolished. However, these countries are still supporting this sector and provide it with different facilities - especially for export - in order to reach marketing forms for its exports that are closer to the uncompetitive types as well as the means they are closer to the monopoly of the minority. Thus, the impacts of wheat world prices on international markets are slim due to aforementioned types. .
