The aim of this paper is to compare the empirical results from three alternative parametric efficiency models using rank-sum test statistic. The comparison involves the technical efficiency scores and their hospitals ranking of the following models: a) Battese and Coelli (1992); b) technical...

This paper presents estimates of technical efficiency for Greek public hospitals using a non-neutral stochastic production frontier. In particular a translog production frontier is estimated for a panel data of 105 public hospitals over the period 1992-93. The estimated efficiency is found to be...
