Effects of social influence on consumers' voluntary adoption of innovations prompted by others

Research on innovation adoption focuses on voluntary adoption, although non-voluntary or prompted adoption decisions are prevalent in real life, especially for high-tech products and services. This study aims to investigate the effect of social influence on consumers' innovation adoption in the context of prompted adoption. In particular, the present paper models the duration of voluntary adoption as a function of social norms, attractiveness of the prompter, number of prompters, and so on. Prior knowledge is not only a control variable, but also a moderating variable for a few social factors. This paper validates models relying on the illustrative application of a mobile gift service called Gifticon. The results provide much insight for marketing practitioners on how to accelerate consumers' adoption behavior and therefore the diffusion of innovative products.

► Non-voluntary or prompted adoptions are prevalent in real life.
► Social influence plays an important role in prompted adoptions.
► Familiarity and likeability of prompters accelerates the adoption.
► Prior knowledge moderates the effects of social factors.
