“…Upper echelons theory suggests that bounded rationality and other cognitive biases play important roles in many strategic decisions (Hambrick, 2007). In the context of mergers and acquisitions, acquiring firm leaders' 55 hubris (Hayward & Hambrick, 1997), narcissism (Chatterjee & Hambrick, 2007) and self-interest (e.g., Deutsch, Keil, & Laamanen, 2007;Gamache, McNamara, Mannor, & Johnson, 2014;Devers, McNamara, Haleblian, & Yoder, 2013) have been shown to influence decisions in the deal-making phase. Leaders' prior experience (e.g., Walters, Kroll, & Wright, 2008;McDonald et al, 2008), functional position (Melone, 1994), gender (e.g., Chen, Crossland, & Huang, 2014), tenure and educational background (Nadolska & Barkema, 2014) also influence decisions regarding whether to acquire a firm and how much to pay.…”
