In particular, we use different  panel data models to assess cost efficiency in these units to account for  unobserved heterogeneity. The results from applying Mundlak’s formulation  to the Pooled stochastic frontier model provides evidence that this model is  not affected by a heterogeneity bias and that the cost efficiency values lie  within a lower and upper bound of the other recent and standard  econometric frontier models. Overall, the analysis shows that assumptions  on unobserved heterogeneity are crucial and that results of econometric  cost efficiency measurement models have to be interpreted with  corresponding caution
