Radial and non-radial DEA models are distinguished on the basis of the presence of slacks. Viewing slacks as a possible source of inefficiency, this paper makes an empirical attempt to assess the relative strengths of these two sets of models in examining the total factor productivity change and...

In this paper, a comparison has been made between the public sector banks and their private and foreign counterparts based on the measures of efficiency and productivity that use quantities of outputs and inputs. Efficiency measures a bank's performance relative to a benchmark at a given point...

Many prior studies on Indian banking efficiency have typically regressed non-parametric estimates of production efficiency on environmental variables in a two-stage process. However, Simar and Wilson (2007) have demonstrated that the studies that use such conventional approaches are invalid due...
