What is Online Reviews and Sales?
Online Reviews and Sales examines the causal impact of consumer-generated online reviews on product sales using econometric models and e-commerce panel data.
Research quantifies review rating elasticity on sales, with studies showing one-star increases reduce revenue by 5-9% (Sparks and Browning, 2011; 1509 citations). Analysis covers review manipulation, sequential bias, and trust formation (Filieri et al., 2015; 799 citations). Over 20 papers since 2011 address cross-platform effects in tourism and retail.
Why It Matters
Online reviews drive e-commerce revenue comparable to advertising, with Sparks and Browning (2011) demonstrating reviews boost hotel bookings via trust mediation. Guo et al. (2016; 962 citations) apply LDA topic modeling to extract satisfaction drivers from reviews, informing product improvements. Filieri et al. (2015) link TripAdvisor trust to word-of-mouth, enabling marketers to prioritize authentic review strategies over paid ads (Goldfarb and Tucker, 2011).
Key Research Challenges
Review Manipulation Detection
Fake reviews inflate ratings, biasing sales elasticity estimates. Econometric models struggle with unobservables in panel data (Appel et al., 2019). Detection requires anomaly detection beyond simple volume checks.
Sequential Bias in Ratings
Early reviews skew subsequent ones, confounding causality in sales models. Panel data from platforms like TripAdvisor shows persistence (Sparks and Browning, 2011). Disentangling requires fixed effects and IV strategies.
Cross-Platform Review Effects
Reviews on one site (e.g., TripAdvisor) spill over to sales on others, complicating attribution. Sparse data hinders multi-platform modeling (Filieri et al., 2015). Standardization across sources remains unresolved.
