講座簡介：

Live-streaming advertising in e-commerce is soaring. Both Amazon and Alibaba have employed this novel marketing model to engage consumers by sequentially exhibiting different products through live-streaming videos. In this paper we adopt a mechanism design framework to model live-streaming e-commerce as a position auction with endogenous provision of product information. We prove that finding the mechanism that simultaneously optimizes position allocation and information provision is NP-hard. Thus we develop several approximation algorithms. Our results show that heuristics that leverage product information provision alone achieve up to 66.9% of the optimal revenue in the worst case, whereas the heuristic that exploits position allocation only may lead to arbitrarily large revenue losses. We attribute the effectiveness of product information provision to its enhancement of the value of ad spots in position auctions. Our work suggests that advertising that focuses on providing differentiating product information—as in live-streaming e-commerce—is more profitable than conventional position-based sponsored search.
