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.

在本文中，我探讨了社会运动中的创新和传播，这是家庭自由创新现象的一部分。这篇文章通过说明社会运动动机与以往针对自我奖励的研究中所探讨的动机有何不同，并研究了这种情况下对自由创新和传播模式的影响，为有关家庭创新的文献做出了贡献。社交运动创新者通常受共同原因（例如寻求新的生活秩序和社会变革）的激励，并创造出解决原因和“系统变革”的创新，而不是针对个人目标的创新。我确定并定义了三种类型的社会运动创新：行为创新，产品创新和符号创新。共同原因的动机还创造了一种新形式的扩散问题，只有通过足够大的人群来传播和消费新产品，行为或技术，才能解决该问题。因此，共同原因动机应鼓励创新扩散，从而减少通常在家庭创新研究中发现的扩散失败问题的风险。
