  Abstract This paper reports the results of a simulation study to evaluate the performance of Banker’s (1993) new asymptotic DEA tests for inefficiency differences between two groups. Their performance is evaluated relative to the performance of conventional parametric corrected ordinary least squares (COLS) tests and the Welch and Mann-Whitney tests used earlier in the DEA literature. We consider five different underlying production functions, four different inefficiency distributions and four different sample sizes in our study. Our results include the following:
