RESUMO

This work applies the residual demand technique to examine the existence of a market power at the free credit segment, specifically into personal loan modality in Brazil. For this proposal the nine biggest banks were selected. They are responsible for more than 50% of brazilian loan modality and their geographic market comprehend all the nation-wide. Many papers about the overuse of the dominant position at the financial market have been produced and the majority results indicate the following diagnose: The hypotheses about the banks act in oligopoly are not rejected. Because of the scarceness of individually information by firm these analysis generally uses data in a very concise way. On one side they render relevant information to subsidize regulatory politics, but on the other side questions about particular geographic market competitive considering different characteristics of prices and products havent been answered. In what concerns to competitive at the financial system, the Central Bank of Brazil (BCB) and the Administrative Council of Competition Defense (CADE) are already developing antitrust analyses directly to concentration acts in the banking market in a more segmentally way. Following this tendency to straiten the analyses focuses on the management after firm entrance at specific relevant markets, was chosen the personal credit modality to evaluate the firms market power working at this market for the following reasons: a) takes significant part of the consumers credit segment; b) his universe is made by individual consumer, in general low information level and reduce exchange power, consequently, a favorable environment to exercise the market power. The results of using the residual demand technique allow to refuse the hypothesis of the above-mentioned banks grant personal loan in a competitive way. This conclusion was also confirmed by a second empiric broach trough panel-data.
