The main concern of this paper is investigated if the Latin American exports is explain for monopolist competition with increasing returns or oligopoly competition with reciprocal dumping. For these propose we used gravitational equation for Latin-American exports for differentiated and homogeneous products. For our econometric estimation we used an extensive sample of exports of 26 Latin-American country's to 136 country's importers of the rest of the world. Our results of the research are the following (a) The Latin-American exports for differentiated goods is explain by monopoly competition and increasing returns with free entry market (b) for homogeneous goods the behavior of regional exports is associated a oligopoly competition with reciprocal dumping (c) The homogeneous goods, with are associated with primary raw materials are yet very important for the economic growth of the Latin-American country's.
