Registered author(s):

    This paper analyzes technical efficiency in Angolan banks from 2005 to 2010 with an innovative Data Envelopment Analysis (DEA) model, the B-Convexity model. The intermediate approach is adopted and the results reveal that efficiency varies among the banks analyzed. Policy implications are derived.
