5. Discussion
In this study, we have extensively analyzed the relationship between the perceived general value of user innovations,the extent to which they diffuse, and the extent to which effort is exerted by user innovators to support diffusion. Our goal has been to investigate the merit of the “under-diffusion of user innovation due to market failure” hypothesis (von Hippel et al., 2014), and to explore factors affecting it. Our analyses were based on a broad sample of consumers in Finland. In the remainder ofthis section, we discuss the evidence in favor of the under-diffusion of consumer innovation hypothesis. Then, we discuss the limitations of our study and offer suggestions for further research. Finally, we consider whether anything can be done to increase diffusion of generally valuable innovations that consumers develop.
