2006
This paper analysis the relationship between market structure and competitiveness in the Brazilian banking industry. First, it quantifies competitiveness by using the statistic-H proposed by Panzar & Rosse and evaluates its relationship with several concentration statistics: Herfindahl-Hirschman, Concentration Ratio, Hall-Tideman and Theil. The concentration indexes lead concentration in CR10 (assets and deposits), while the concentration of credit reduces. There is a monopolistic competition among Brazilian banks.
