Introduction Strategy for New Products with Positive and Negative Word-of-Mouth
研究负面信息占主导的产品扩散模型，讨论最优广告时机策略，并以电影《甘地》在达拉斯地区的观影人数预测为例进行应用。
Existing innovation diffusion models assume that individual experience with the product is always communicated positively through word-of-mouth. For certain innovations, however, this assumption is tenuous since communicators of the product experience may transfer favorable, unfavorable, or indifferent messages through word-of-mouth. This paper examines a diffusion model for products in which negative information plays a dominant role, discusses its implications for optimal advertising timing policy and presents an application to forecast attendance for the movie Gandhi in the Dallas area.
