论文摘要
本文分析了一种与基于案例的人A La Gilboa和Schmeidler（1995,1996,1997）的创新扩散模型，他们决定是根据他们及其社交邻居以前的消费经验消费现有的或新产品的。我分析了扩散模式如何随着个人特征，创新特征和社交网络而变化。特别是，与增量创新相比，根本创新会导致更高的初始速度，但加速度较低。社交网络具有更强的整体社交关系，较低的同质性或从早期采用者中获得的评论的较高暴露速度加快了创新的扩散。
This paper analyzes a model of innovation diffusion with case-based individuals a la Gilboa and Schmeidler (1995,1996,1997), who decide whether to consume an incumbent or a new product based on their and their social neighbors' previous consumption experiences. I analyze how diffusion pattern changes with individual characteristics, innovation characteristics and social network. In particular, radical innovation leads to higher initial speed but lower acceleration compared to increment innovation. Social network with stronger overall social tie, lower degree of homophily or higher exposure of reviews from early adopters speed up diffusion of innovation.
