Grounded in the heuristic-systematic model, we explore the relationships between systematic cues, i.e., review and rating inconsistencies, and review helpfulness. We also investigate how reviewer expertise and hotel rank moderate these inconsistency-helpfulness links, serving as heuristic cues. Applied to a real-world hotel dataset collected from TripAdvisor, our findings show that review inconsistency negatively influences review helpfulness, while rating inconsistency positively affects it. Furthermore, we find that reviewer expertise negatively moderates the review and rating inconsistency-helpfulness links, while hotels that rank low positively moderate both links.

As more companies encourage employees to volunteer a small portion of their work time and match their charitable contributions, disclosing these prosocial acts on social media platforms has become more common. Building upon social capital theory, we apply a mixed-method approach to investigate the relationship between the disclosure of prosocial behaviors and the attainment of social capital on SNSs. Our first exploratory study applies qualitative interviews to explore the factors that moderate the relationship between the disclosure of prosocial behaviors and the attainment of social capital. Our second study utilizes a randomized online experiment in the U.S. to test the causal effect of prosocial behavior disclosure on social capital attainment online, as well as two moderators of this relationship. A post-hoc replication study of our experiment is conducted in China. We find that the disclosure of prosocial behavior increases relational and structural social capital on SNSs but find no evidence of the impact of the disclosure of prosocial behavior on cognitive social capital. The effect becomes stronger when one's prosocial behavior is disclosed by others (rather than by oneself) in the U.S. sample. Our findings inform SNSs users to make informed decisions regarding disclosing prosocial behaviors to attain structural and relational social capital.

Using the University of California, Berkeley graduate admission data as an illustrative example, we show that PSM can produce biased estimates of the Average Treatment Effect (ATE) in such contexts. Through a simulation study, we demonstrate that PSM generally fails to adequately reduce bias for the ATE when a confounder is also an effect modifier, while IPW yields less biased estimates with lower Mean Squared Error (MSE).

In this paper, we investigate whether a streaming platform should purchase external consumer data to improve ad-targeting levels, whereby it gain revenue from cost-per-mille (CPM) and cost-per-click (CPC) advertising. We explore how advertising intensity and consumer advertising fatigue interactively determine the data purchase decision and the optimal ad-targeting level of the streaming platform. Our findings indicate that the platform with low advertising intensity or high consumer advertising fatigue is more likely to purchase external consumer data because the ad-driven CTRs are low in these cases. An unexpected finding is that the amount of consumer data purchased by the platform increases with the intensity of privacy concern when advertising intensity is low or when both advertising intensity and fatigue level are high. In these scenarios, the privacy invasion effect resulting from purchasing external consumer data is low due to the low ad-driven CTRs. After purchasing consumer data, to compensate for the privacy invasion effect of targeted ads on consumers, the platform should lower the advertising intensity if and only if the advertising fatigue level is low. Furthermore, we demonstrate that if the platform simultaneously decides on advertising intensity and ad-targeting level, purchasing external consumer data results in a Pareto improvement when the organic CTR is low, benefiting both consumers and the streaming platform.

Drawing on the constructivist theory of visual perception, we propose a cognitive inference process in which shoppers utilize the background objects in UGIs that contextualize a product (e.g., a snow-covered mountain implying cold weather) to infer its features (e.g., the warmth of a jacket). As a result, the contextual cues in UGIs play a critical role in facilitating future buyers' purchase decision-making. Our empirical probes using data from an online outdoor gear and clothing retailer confirm this conjecture by demonstrating that product contextualization in UGIs increases a review's perceived helpfulness and improves sales. By contrast, the contextual cues in the review text only assist buyers' purchase decision process when they contextualize product functionality (e.g., the windproof of a coat). Yet, they do not work for aesthetic attributes (e.g., the color of a coat). We leverage an experiment to explore the relevant mechanism. In the sales analysis, we reveal that not all image content considered helpful would positively affect sales. For example, after we account for the contextual cues in the UGI, the mere presence of an image in product reviews does not affect sales. On the other hand, although illustrating product malfunction in a UGI does not increase its helpfulness, such content hurts sales.
