Sebastian Burchhardt develops a game theory model that analyzes the possible behavioral patterns of employees during M&A processes and the impact of such patterns on the success of the transaction itself. The result is the development of a principal-multi-agent model that allows for endogenous contest entry driven by identity. In addition, the model proposes guidance for practical M&A management.  Contents Identity and Competition in an Organizational Context The Social Identity Approach in Corporate Mergers and Acquisitions Identity-Driven Contest with Endogenous Entry Identity-Driven Group Contest with Endogenous Entry Implications of the Basic Model Implications of the Extended Model for M&A  Target Groups Researchers and students in the fields of mergers & acquisitions, microeconomics and organization theory Practitioners in these areas  The Author Dr. Sebastian Burchhardt completed his doctoral studies under the guidance of Prof. Dr. Peter-J.
