This study aims to assess the degree of market power in the distribution sector gasoline C, in Brazilian regions, from 2002 to 2008. To this end, based on the Theory of the New Empirical Industrial Organization (NOIE), specifically, the model proposed by Bresnahan (1982) and Lau (1982). A dynamic version of the model was also estimated. The results indicated that, except for the northern region to the static model, the distributors of gasoline C does not act as price takers. At the other extreme, the hypothesis of perfect collusion between them was rejected. It was found that, in many regions, parameters proved to be sufficiently low, suggesting that the distributors have high competition with each other.
