This paper examines the role of the institutions that affected Brazilian and Argentinean grain agroindustrial systems in this decade, using the New Institutional Economics as theoretical reference. Important differences mark the performance of the production of grains in these countries, despite Brazil and Argentina having followed the same model of development based on the process of import substitution and a closed economy. In addition to the edapho-climatic factor which brings initial advantages to the production of grains in Argentina, in general, this country has always had greater insertion in the international market due to its smaller population. The changes in the institutional environment and its effects on the recent performance of soybean and corn production in Brazil and Argentina are the objective of this work.
