Abstract:

In this paper we have two main goals. From a theoretical point of view we intend to develop an improvement to the DEA variable selection models. It is in the variable normalisation step that this improvement takes place. From a practical point of view we intend to measure an energetic efficiency of the 27 Brazilian states. A state achieves this efficiency when it has high values of some socio-economic indexes and low level of energy consumption. We used the non-parametrical approach of Data Envelopment Analysis (CCR and BCC models). We also used the inverted frontier DEA model.
