Market Segmentation and the Diffusion of Quality-Enhancing Innovations: The Case of Downhill Skiing
通过美国可拆卸缆车扩散的计量分析，首次实证表明企业采用技术创新会降低本地竞争对手也采用该创新的可能性，并构建模型解释这一负向激励。
We report econometric results concerning the diffusion of detachable chairlifts in the United States that provide the first empirical evidence that the adoption of a technological innovation by a firm decreases the likelihood that a local competitor will also adopt it. We model the effect that an innovation in service speed has on a f's incentive to differentiate the quality of its service from that of its competitors. In our model, the incentive to adopt is negatively related to the number of competitors who have already adopted. Our empirical results support this hypothesis. © 2003 President and Fellows of Harvard College and the Massachusetts Institute of Technology.
