“…Despite the view that observers can perceive benefits from a product claiming co‐creation, there is little evidence explaining this effect (Kristal et al, 2016) in comparison with the amount of studies explaining the benefits (Echeverri & Skålén, 2011) and risks (e.g., Echeverri & Skålén, 2011; Gebauer, Füller, & Pezzei, 2013) of co‐creation as a product development strategy. There are few experimental studies on the effect of claiming consumers' participation in the product development process on observers' responses (e.g., Costa & Coelho do Vale, 2018; Fuchs & Schreier, 2011; Fuchs et al, 2013; Kennedy, 2017; Kristal et al, 2016; Kristal, Baumgarth, & Henseler, 2018; Schreier et al, 2012; Thompson & Malaviya, 2013; Van Dijk, Antonides, & Schillewaert, 2014). In those studies, synthesized in Table 1 and discussed in the next paragraphs, some mediating and moderating factors have been tested to produce better explanations of how consumers' participation claim influences observers' evaluations of the announced product.…”
