内容简介：

Vertically differentiated products in a competitive market often share common attributes (e.g., location value, infrastructure, or technologies) provided by third-parties. In this study, we characterize how common attributes affect high- and low-quality firms in their offerings of individual attributes and pricing, and consequently affect market competition and social welfare. First, we disentangle three distinctive effects of common attributes on vertical competition, and identify a “bottom-up” influence through which common attributes affect the low-quality firm greater than the high-quality firm. Second, we show that more desirable common attributes have different implications for vertical competition in different product markets. Finally, we examine a retail platform’s commission policy when its infrastructure constitutes common attributes for vertically differentiated vendors, and identify a “top-down” influence through which the commission policy affects the high-quality firm greater than the low-quality firm in moderating the impact of common attributes.
