 note = {application/pdf, IDP000869_001, Is the distance between the product characteristics of firms in an industry  getting closer or not in competition? Although many studies have been conducted on  differentiation to get farther and imitation to get closer, neither has been analyzed within t he same framework. Therefore, this study introduces the concept of imitation into a  Hoteling model on differentiation. We show that although firms are more profitable if  they maintain differentiation, they face a prisoner’s dilemma in imitation and therefore try to imitate from each other as much as possible, which decreases their profits. As a  result, competition brings the distance closer by imitation and promotes the  standardization of product characteristics in that industry.},
