In this article the efficiency of production unit is defined and measured using the potential and real benefit. Properties, defects and advantages of these measures are presented. Essential problems which arose with their construction are presented, too. In the iast part, the empirical example of application is given. (based on real data from the Polish bank sector). It illustrates the problem matter and presents numerous important interpretations of results received.

In this article the definitions of global and local returns to scale (proposed in the DEA literature) are discussed. A new variant of the definitions of local returns to scale (increasing, decreasing or constant) is proposed. Its equivalence to the three practical methods found in the literature is proved. An empirical example (based on real data from the Polish energy sector) is presented
