摘要：International market for some agricultural commodities can be characterized by oligopoly, in which participants behave in a non cooperative manner, provoking marketing disputes. According to this scenario, strategic trade policies have been utilized to as an instrument of market share contents by international market members. Hence, when a country adopts some strategic trade policy, impacts of such policy are felt by other market participants. A subsidy granted by an exporting country, for instance, may result on a raise in exports; whereas taxing production of exports may work as a deterrent to shipments to the international market.
