讲座提纲：

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. For information goods, the high-quality firm improves individual attributes in response to more desirable common attributes, but the low-quality firm reduces individual attributes. For industrial goods, both firms mostly reduce individual attributes. In equilibrium, more desirable common attributes weaken the dominance of the high-quality firm for information goods, whereas the weakening effect is negligible for industrial goods. For both product types, a major portion of the benefit from desirable common attributes is passed through to end consumers. 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. We show that more advanced infrastructure motivates the platform to implement a higher commission, which leads both firms to offer inferior individual attributes.
