  The importance of innovation for sustained national and firm competitiveness is widely acknowledged by scholars, practitioners and policymakers (Cho & Pucik, 2005; OECD, 2012). Firms with higher levels of innovation will be more successful in responding to changing environments of deepening globalisation, increased competitiveness, rapid technological change and shorter product life cycles (Manso, 2011; Rosenblatt, 2011) and in developing new capabilities that will allow them to achieve better performance (Montes et al., 2004). Highly innovative firms ensure that a broad range of employees are involved with innovation and recognise the importance of employee-driven innovation (Høyrup, 2012). Such firms are also likely to have leaders with behaviours that are conducive to enhancing employee-driven innovation, of which knowledge-sharing is likely to be critical (Mumford et al., 2002).
