Abstract: Considering the fundamental role of banking system in different economies, an efficient banking system has always been regarded by governments; also, establishment of an efficient network of branches is considered as a major strategy to adjust efficiency improvement programmes within a bank. Accordingly, the present paper aimed to calculate the technical efficiency of 128 branches of Tejarat Bank in Isfahan, Iran, during 2007-2009 through stochastic frontier analysis, Translog production function, and maximum likelihood estimation. The model used in the study was time-varying in efficiency model developed by Battese and Coelli (1992). The obtained statistical results from data fitness indicate that average technical efficiency of Tejarat Bank branches in Isfahan is 95.36% during studied period; that is, 95.36% of loans payable in full efficiency, assuming the same level of inputs, was paid by Tejarat Bank of Isfahan during a three-year period (2007-2008). Moreover, mean technical efficiency of these branches decreased over time.
