Resumo
Using the model proposed by Coelho, Mello and Resende (2013), which extended the structure of Bresnahan and Reiss (1991) for the banking industry, we measure the competitive effect of public ownership and private banks in the Brazilian market, based on data from 2010. From the variation in the number of public and private banks in banking markets and using the total income of the adult population to measure the size of the market, we estimated the private bank entry behavior in these markets and if this behavior is affected or not by the presence of public banks. We identified that the markets in which there are private bank duopoly are 21% larger than the markets in which there are private banks monopolies, while the markets in which there are duopolies with public and private bank are lower than the markets in which there are monopolies of private banks at 15%. This may indicate that the presence of private bank increases competition in banking markets and that the presence public bank reduces it. We also found that the presence of privatized banks in the sample introduced distortions in the results of this study, probably due to previous public nature of these banks. The results found, excluding of the sample municipalities with privatized banks, suggest that public and private banks compete for similar sized markets, unlike the results found in the total sample.
