Professor Frank Kalenberg is a regular collaborator of the Faculty of Economics and Business. For the past 10 years, he has been going to Donostia every year as part of the Erasmus+ mobility program. There, as part of the course taught by Professor Eduardo Malles, he gives a week-long lecture on cost accounting tools used in Germany and compares them with those used here.

This year, however, on the occasion of the retirement of Professor Eduardo Malles, he wanted to come as a listener and listen to his lectures. For Professor Frank Kalenberg the experience has been very interesting, both for the approach adopted in the classes, as well as the way of giving them and their content, so that he has considered for his classes to combine what he does at his university, with what he has observed here.

For the future, the collaboration with Frank will have continuity, since he will continue working with Eduardo's substitute and the teacher who teaches the subject in Basque in Donostia.
