We are currently working on three ongoing projects:

- Choosing factors (inputs and outputs) in DEA, what is the best technique to apply?

- Techniques for breaking the tie in the efficient set, that is how to rank efficient units, as all of them display an efficiency score of 100%

- Evaluating the efficiency of units performing more than one activity and in the particular setting where some resources are shared among these activities. We apply our approach to bank branches as we denote today a stronger emphasis on the sales part of a branch's activity
