摘要:This paper provides a conceptual framework for the banking efficiency study and a survey of the previous banking efficiency literature. The discussions include the concept of efficiency measurement, different types of efficiency, methodology as well as the approaches of input and output variables. The possible bank efficiency determinants or factors that could explain the differences in efficiency of the bank are also discussed. The findings show that no estimation techniques dominate over the other with DEA widely used to measure the technical efficiency while SFA mostly used to measure the cost efficiency. The paper also found that the intermediation approach is the common approach used to decide the appropriate input and output variables.
