Competence Center Mergers & Acquisitions

Mergers and acquisitions are an important engine of transformation in the global economy with significant influence on national and international production networks, market relations and competitive dynamics. Since they can trigger strong financial market reactions and frequently have far-reaching consequences for customers, employees, and suppliers, they are usually of great public interest. Yet, acquisitions are generally associated with a high degree of complexity and risk and prior research indicates, that the majority of corporate transactions fails to realize their intended objectives. In the competence center for Mergers and Acquisitions we empirically examine this phenomenon.

In different research projects we analyze various aspects of the transaction process: from the strategic decision-making phase to the organizational implementation and long-term implications of non-organic growth. We try to identify dysfunctional behavioral patterns and scrutinize possible solutions. To do so, we examine the role and interaction of a number of different actors such as dedicated M&A departments, top executives, supervisory boards, analysts, and advisors and work with different types o primary and secondary data, such as accounting and stock-market data, interviews, shareholder meetings, advisor track records, and internal M&A archives. A particular emphasis of our recent work lie in the area of acquisition program and the acquisition practices of active «serial» acquirers, including the development of digital tools for the management of the transaction process.
