Este artigo calcula índices robustos de eficiência para 3663 agências do Banco do Brasil utilizando o método jackstrap que combina técnicas de reamostragem com a analise envoltória de dados (DEA). Os resultados obtidos permitem identificar as agências empresariais e públicas como outliers. Consequentemente, o uso dessas unidades atípicas como referencial para as demais unidades conduz a sérias distorções sendo, pois, desaconselhado. Além disso, a inclusão do número de contas como produto modifica, substancialmente, os índices de eficiência já que dilui o impacto de outras importantes variáveis, tais como a rentabilidade financeira das agências. Finalmente, nossos resultados sugerem, ainda, que as unidades mais eficientes têm um maior número de clientes, servem ao agronegócio e localizam-se em pequenas municipalidades.
