The members of the chair of foundations of business administration and theories of the firm foster a multi-paradigm view in research and teaching in management studies and their sub-disciplines. In particular, we concentrate on management sub-disciplines like organization studies, leadership, corporate communication, corporate social responsibility (CSR), business ethics, and the theory of the firm. By means of conceptual and empirical research we contribute to theory development in management studies, using different schools of thought from various disciplines such as philosophy, economics, political science, sociology, (social) psychology and communication studies. We systematically analyze their contribution to questions arising in business administration. We educate students and young academic talents in various theoretical perspectives and enable young academic talents to take part in international and interdisciplinary discourse.
