In this study we grasp the wealth of extant research in the field of M&As. We conducted a bibliometric study of 635 articles on strategic management and international business research published in 34 highly ranked management journals between 1983 and 2012. We performed citation, co-citation and factor analyses to uncover the issues examined by scholars, the main theoretical approaches and themes researched. The results show a relative shift from economic and financial approaches to knowledge-based and organizational learning perspectives in recent years. There was also an evolution from assessing the performance of firms after an M&A to seeking an understanding of what may drive synergy creation after the integration process. Furthermore we observed an increasing interest in cross-border M&As. We discuss our findings, identifying gaps and suggesting paths for future research.engMergers and AcquisitionsCorporate TakeoversBibliometric StudyLiterature ReviewAn overview of three decades of mergers and acquisitions researchjournal article
