For that, it was used the model Cotterill, Franklin and Ma (1996) which considers an oligopoly market with differentiated products, supported by the New Industrial Organization Empirical (NEIO). The results show that when the cross-elasticities are analyzed, the segment can be separated into two markets where in which the Gol and the Palio compete, as well as the Celta and the Uno, characterized as substitute goods from each other.
