This book describes the debate on mergers and acquisitions in the setting of family firms. It provides scholars and students with an overview on the ongoing literature on family firms' acquisition decisions, emphasizing the main theoretical perspectives adopted by the scholars. Furthermore, it illustrates the empirical findings with regard to the family firms' propensity to adopt M&A strategies and to the nature of these transactions (e.g.: related, unrelated, cross-border). This book also offers new evidence on the role of target company sustainable performance when family firms select the company to buy, by shedding light on the relevance of the boardroom structural and demographic diversity.
