Die internationale Beachtung der Forschungsergebnisse in der Wirtschaftsinformatik hat in den letzten Jahren an Bedeutung gewonnen. Dabei wird dem kritischen Diskurs ein wachsender Stellenwert eingeräumt. Hier gilt es, den wissenschaftlichen Nachwuchs in der Konzeption und Durchführung der...

This paper presents simple su±cient conditions under which optimal bunches in adverse-selection principal-agent problems can be characterized without using optimal control theory.

Capacity Remuneration Mechanisms (CRM) can be used in power markets to overtake market failures, reaching security of supply. However, investment in capacity is a dynamic process, that depends on the evolution of prices and costs overtime. In our paper we study the capacity remuneration value...
