AB In the framework of Cognitive Approach, this paper proposes a new method to identifystrategic groups (SG) using Data Envelopment Analysis (DEA) methods. Twoassumptions are maintained in the SG literature: first, firms grouped together valueinputs and outputs similarly, and, second, some degree of stability in those valuationsshould be identified. Virtual weights obtained from DEA are extremely useful in thevaluation of the strategic variables, but a problem emerges when longitudinal analysis isperformed. This problem is addressed by defining a long run DEA evaluation. SGs aredetermined by means of Cluster Analysis, using virtual outputs and virtual inputs asvariables and Spanish savings banks as observations. The traditional method ofdetermining SGs by clustering on the original variables is also applied and the resultsare compared. It is shown that the long run DEA weights approach has advantages overthe traditional methodology.
