This book provides scholars and practitioners in mergers and acquisitions (M&As) with a solid foundation for further research. M&As continue to shape the economic landscape across the globe. While there is already a huge body of scholarly work on the subject, findings appear contradictory and academics and practitioners often struggle to understand what factors make M&As successful.Due to the lack of an agreed-upon definition, research findings appear contradictory, while in fact they are often simply not comparable. To address this, the book rethinks how we measure key umbrella constructs. It specifically focuses on the conceptualization phase of the measurement process, often taken for granted in the current research.
