Generalising a Pricing Effect
在一项针对快速消费品的大规模实地实验中，发现不同产品或品牌的价格弹性大致相同，且不受价格变动方向、速度或品牌历史定价的影响，这与传统观点相悖。
In an extensive field experiment with fast-moving branded consumer goods, price elasticities are found to be much the same for different products or brands, for prices going up or coming down, at different speeds, and irrespective of the brand's previous pricing history. These results differ radically from the view that individual products and brands have their own distinct elasticities. Copyright 1990 by Blackwell Publishing Ltd.
