Abstract

This study generalizes the test performed by Simar and Zelenyuk (2007) to examine differences in the technical efficiency among $$L$$L groups within an industry (where $$L \ge 2$$L≥2 ). For this purpose, the $$L$$L groups are divided into pairs and each group is compared with all other $$L - 1$$L−1 groups. The $$L - 1$$L−1 groups can then be classified into three cohorts: those performing better, equally and worse, relative to the benchmark group. For illustration purposes, annual data for Vietnamese banks covering the period 2005‒2012 is used.
