Social movements and free innovation
探讨社会运动如何驱动家庭中的免费创新，发现共同目标动机（如追求新生活秩序和社会变革）促使创新扩散，减少传统家庭创新中的扩散失败问题。
In this article, I explore innovation and diffusion from social movements as part of the phenomenon of free innovation in households. The article contributes to the literature on household innovation by illustrating how social movement motivations may differ from motivations examined in prior studies focused on self-rewards, as well as examining the implications for free innovations and diffusion patterns in this setting. Social movement innovators are typically motivated by a common cause (such as a quest for a new life order and societal change) and create innovations that address a cause and “system change” rather than individual goals. I identify and define three types of social movement innovation: behavioral, product, and symbolic innovation. The common-cause motivation also creates a new form of diffusion problem that can only be solved through the spread and consumption of new products, behaviors, or techniques by a sufficiently large crowd. Common-cause motivations should thus encourage innovation diffusion, thereby reducing the risk of the diffusion-failure problem usually observed in household innovation research.
