This paper investigates the consistency of efficiency scores obtained from the stochastic frontier analysis and data envelopment analysis methods. We estimate cost efficiency and economies of scale based on an unbalanced panel data set of Chinese banks over the period 1994 to 2007. The results...

This study aims to investigate the significance of adequately accounting for heterogeneity in banking efficiency. It compares different specifications of stochastic cost frontier models which attempt to account for bank heterogeneity in various ways. This study compares the estimated parameters...
