The overlooked influence of personality, idiosyncrasy and eccentricity in corporate mergers and acquisitions

Purpose Merger waves have typically been viewed through the prism of either corporate strategy or macro-economics. This paper aims to broaden debate about factors that cause – or are associated with – mergers/merger waves over a 120-year period. It ascribes “personalities” to six distinct waves and draws an overarching conclusion about how merger architects are viewed. Design/methodology/approach Databases and interviews are used to piece together detail about CEOs associated with six distinct and recognized merger-waves during a 120-year focal period. The study establishes and defends, a priori, principles for interrogating data to get a sense of each wave-era’s corporate personality/idiosyncrasy. For each era, two exemplar CEO-profiles are presented and – through inductive-reasoning – held out as representative. Findings Distinct personalities are associated with six merger waves. Each wave is given a summary anthropomorphic description which conveys a sense that it may be viewed as the non-rationale expression of aggregate and historically distinct CEO behavior within a circumscribed timeframe. Research limitations/implications The work’s key limitation – explicitly acknowledged – is that it amassed data/evidence from disparate historical sources. However, the authors have developed and defended principles for addressing this concern. Practical implications Improved investment analyses, in particular. The work prefigures formal establishment of a new variable-set impacting share-price prediction. Social implications The paper offers a perspective on how psychological/personality-related variables impact management decision-making, creating something of a bridge between mostly non-overlapping research disciplines. Originality/value The paper broadens debate about how and why merger waves occur. It removes the exclusive analysis of merger waves from the hands of economic historians and strategic management theorists.
