Just before the summer break I get this nice news in my mailbox:
Dear Prof. Ingmar Schumacher,
I am pleased to inform you that your paper has been accepted for publication in the European Journal of Operational Research.
So what is this paper about? It is a theoretical contribution together with Professor Georg Müller-Fürstenberger from the University of Trier on how inter-regional externalities can become overwhelmingly crucial if one considers a dynamic setting.
