CEO Overconfidence and International Merger and Acquisition Activity
AbstractThis study examines the role that chief executive officer (CEO) overconfidence plays in an explanation of international mergers and acquisitions during the period 2000–2006. Using a sample of CEOs of Fortune Global 500 firms over our sample period, we find that CEO overconfidence is related to a number of critical aspects of international merger activity. Overconfidence helps to explain the number of offers made by a CEO, the frequencies of nondiversifying and diversifying acquisitions, and the use of cash to finance a merger deal. Although overconfidence is an international phenomenon, it is most extensively observed in individuals heading firms headquartered in Christian countries that encourage individualism while de-emphasizing long-term orientation in their national cultures.
