Abstract

Although corporate acquisitions are ubiquitous a large number of M&A fails. One explanation for such failure is the hubris hypothesis for corporate takeovers. A decision maker affected with hubris (or overconfidence) will overestimate his abilities in raising potential synergies and is likely to make investment decisions destroying shareholder wealth. The growing literature on CEO hubris proposes various ways to measure hubris. We present these indicators and discuss possible advantages and drawbacks.
