This bibliometric review examines the extant research on M&As in the top five strategic management journals during a ten years period – from 2000 to 2009. The 90 articles identified in these top journals denote an eclectic theoretical focus with the prevalence of four theories – resource-based view, transaction costs, agency theory and institutional theory. We present a brief analysis of the key issues in M&A research, as well as the samples and theories more commonly used. We conclude by presenting a broad discussion comprising the methods used, the research questions investigated, the type of articles, as well as limitations and avenues for future enquiry.engMergers & acquisitionsStrategic management journalsBibliometric studyjournal article
