“…A justification might rely on the uncertainty, risks, huge monetary investments and late returns on investment involved in the innovation process, with consequences for technology failure (Evans, 2011;Alkemade and Suurs, 2012;Pantano et al, 2013), which could discourage retailers to afford the technology-based innovations adoption process. For instance, uncertainty for retailers would be related to the consumers' acceptance of the technology, and the level of system usage, as well as the risk of obsolescence (in terms of obsolescence of components, threats of substitution with newer technology, and damages by users; Pantano and Di Pietro, 2012;Pantano et al, 2013;Zhu et al, 2013). Hence, the diffusion and utilization may be affected by several externalities able to reduce the exploitation of all benefits of the innovation.…”
