Scores vs. stars: A regression discontinuity study of online consumer reviews

The Dimensions and Roles of Online Content in Social Commerce: A Systematic Literature Review and Future Research Agenda

“…Our manual analysis of the literature found a substantial focus on encouraging more users to engage with ratings as well as efforts to alleviate the negative impacts such as dispersion, fake ratings, and unfair ratings (Lee et al, 2021; Liu et al, 2021; Monaro et al, 2020). Also, authors have compared various kinds of metrics, such as scores and stars, and analysed their distinctive impact on sales (Lee, 2018; Wang et al, 2019). In the social media context, authors have shown how metrics such as likes and tweets influence a seller's reputation and subsequent consumer intentions, behaviors, and sales (Kim & Kim, 2018).…”

“…Similarly, review sites introduce novel metrics (coolness and funniness of reviewers) to assess the quality of posted reviews (Lee, 2018). Finally, the different representations of ratings (scores vs. stars) can alter users' perceptions (Wang et al, 2019). These studies highlight the platform's impact on content characteristics and relevant outcomes.…”

“…This section summarizes the research articles exploring factors that would help mitigate unfavorable outcomes. Table 13 lists To reduce information overload and asymmetry, studies have examined what factors lead to helpful reviews Wang et al, 2019). Review helpfulness (12) emerged as the most popular mitigation measure for information overload and fake review detection.…”

Robust Regression Discontinuity Estimates of the Causal Effect of the TripAdvisor’s Bubble Rating on Hotel Popularity

“…However, in contrast, Duan et al (Duan et al, 2008) did not find a significant influence of the average rating on movies' box office revenues. Even more interestingly, according to a recent regression discontinuity study of online consumer reviews the star presentation can create negative, rather than positive, jumps at cutoffs (Wang et al, 2019). The authors provide the following reasoning.…”
