Resumo

Este estudo evidencia que houve um incentivo para a ocorrência das fusões e incorporações de bancos brasileiros no período após a implantação do Real. Este resultado refere-se a constatação de que existe economias de escalas nos bancos brasileiros com ativos acima de um bilhão de reais. Tal conclusão e obtida estimondo-se uma fronteira estocástica de custo translog por maxima verosimilhança e considerando-se a possibilidade de ineficiências dependerem de algumas variáveis relacionadas com o problema de Moral Hazard.
