A key challenge for open initiatives is to attract participants (Healy and Schussman 2003; Chesbrough and Appleyard 2007). This challenge grows with the increase in comparative opportunities and creates competition among initiatives for talented contributors (Dahlander and Gann 2010; Bonaccorsi and Rossi 2003). In this realm, a contributor will not volunteer within an uncomfortable environment (Shah 2006). Currently, the influence of contextual changes on volunteering is unclear (Boudreau 2010), especially within open collaborative initiatives (Fang and Neufeld 2009). The interaction between individual user traits and institutional settings is a research challenge (von Krogh et al. 2012, Crowston et al. 2012).
