Jens-Christian Friedmann

My research focuses on how firms develop technological capabilities in alliances, acquisitions, and divestitures within international settings. More specifically, interest lies in how firms innovate and create value through sequences and interdependencies among these distinct transaction modes. I investigate these topics empirically by relying on archival data and using quantitative methods. Theoretically, my research draws primarily from the resource pathways and knowledge management literatures.

Aside from my research, I teach courses on statistical and econometric methods for research and business analytics, intellectual property protection, and corporate strategy at the MSc level. I also engage in thesis supervision on M&As and alliances.
