- 요약This dissertation studies how information and incentives in digital markets affect the strategic interactions among market participants, with implications for three different digital environments. The first chapter studies how the attribution algorithms used in online ad auctions affect the strategic interactions between advertisers and publishers, and it investigates optimal attribution strategies for advertisers. Because online advertisers typically advertise with several publishers to increase their reach, users may be exposed to ads from multiple publishers before converting. The attribution challenge for an advertiser is to measure the contributions of each publisher's advertising on conversions. These attributed conversion measures are crucial because they serve as inputs into the algorithms that advertisers use to determine bids in future ad auctions. The attribution challenge is aggravated by the fact that publishers typically have access to more information than advertisers, such as user behavior on their sites. This information asymmetry can lead to a moral hazard problem: publishers can exploit their information advantage to target ads to users who are likely to result in attributed conversions, rather than to users with large incremental ad effects. To investigate this misalignment of interests between advertisers and publishers, I cast the attribution problem as an incentive design problem. Using a structural model, I first characterize the dynamic incentives created by standard attribution algorithms and derive the advertiser's optimal strategy. I find that the advertiser's optimal strategy takes the form of team incentives, where each publisher is compensated only when a conversion is preceded by an ad impression by only that publisher. Counterfactual analysis shows that the optimal strategy increases the advertiser's ROI on the order of 20-40% compared with standard attribution algorithms. The findings highlight the importance of considering the dynamic incentives that measurement tools generate.The second chapter is based on joint work with J. Miguel Villas-Boas and Mingduo Zhao. In online marketplaces, consumers rely on reviews to make informed purchase decisions, making the presence of fake reviews detrimental. Previous literature implies that products with fake reviews can display some patterns in review distribution, such as a higher discrepancy in ratings. Consumers might take this pattern into account when making their purchase decisions. In this chapter, we explore the interplay between fake reviews and ratings discrepancy, and their impact on consumer demand, while controlling for average product ratings. First, using a data set with fake review labels, we find that product ratings discrepancy is positively correlated with the probability that the product has fake reviews. Second, through an identification strategy exploiting ratings discrepancy changes due to rating distribution rounding, we find evidence consistent with a negative causal impact of ratings discrepancy on consumer demand. Then, we conduct two experiments to establish and quantify the mechanism of the impact of ratings discrepancy on consumer demand through consumer suspicion of fake reviews. The first experiment shows that higher ratings discrepancy increases consumer suspicion of fake reviews, and the second experiment shows that heightened suspicion reduces consumer willingness to pay. Together, these findings reveal that consumers use ratings discrepancies as a signal of fake reviews, and this suspicion significantly impacts their purchase decisions. The findings highlight the importance of understanding the relationship between fake reviews, ratings discrepancies, and consumer demand in online marketplaces.The third chapter is based on joint work with Xin Chen and Matthew Osborne. In the contemporary marketing environment, targeted and personalized marketing has become central to firm strategy. While existing literature has predominantly examined the personalization of individual marketing instruments in isolation, this research demonstrates the limitations of such approaches. We develop a structural model using data from a large-scale field experiment from a leading Chinese grocery e-tailer. The counterfactual analysis shows that third-degree price discrimination alone increases profits by only 2.4%. However, when the firm integrates price personalization with personalized broadcasting requirements, the profit gains rise to 40.3%. The findings underscore the importance of cross-functional coordination in personalization strategy and provide a methodological framework for future research on multi-dimensional personalization.
