Online innovation communities are an important source of innovation for many
organizations. While contributions to such communities are typically made
without financial compensation, these contributions are often governed by
licenses such as Creative Commons that may prevent others from building upon
and commercializing them. While this can diminish the usefulness of
contributions, there is limited work analyzing what leads individuals to impose
restrictions on the use of their work. In this paper, we examine innovators
imposing restrictive licenses within the 3D-printable design community
Thingiverse. Our analyses suggest that innovators are more likely to restrict
commercialization of their contributions as their reputation increases and when
reusing contributions created by others. These findings contribute to
innovation communities and the growing literature on property rights in digital
markets
