Online Product Reviews-Triggered Dynamic Pricing: Theory and Evidence
Juan Feng, Xin Li, Xiaoquan (Michael) Zhang (2019). Online Product Reviews-Triggered Dynamic Pricing: Theory and Evidence. Information Systems Research. https://doi.org/10.1287/isre.2019.0852.
Plain-English take
The model predicts that firms can manipulate pricing to influence reviews and sales and can dynamically adjust prices in response to online word of mouth; the panel-data difference-in-differences study is presented as empirical support for those predictions. For your marketing: Use this as a pricing or packaging hypothesis and define outcomes to measure; estimate effects with your own customer mix and willingness-to-pay evidence.
How much weight to give this
2.5/5 Evidence needs cautious interpretation
The 1–5 evidence-check score is a practical reading aid, not a formal peer review or a probability that a conclusion is true. It combines design strength (2 points), sample reporting (1), comparison/control clarity (1), and how much of the paper could be checked (1). Access affects how confidently this directory can assess a study, not the study's underlying quality. Blinding is reported separately because it is not relevant to every design.

Scope and transfer
Limitations to keep in view
Not stated in the publisher abstract; the page does not provide enough detail to identify sample-specific external-validity limitations.
Possible founder application
Use this as a pricing or packaging hypothesis and define outcomes to measure; estimate effects with your own customer mix and willingness-to-pay evidence.
Evidence access
Publisher abstract/metadata retrieved; consult the linked paper for full methods and tables.
The publisher describes a panel-data study of prices and reviews using difference-in-differences, and says the study offers empirical support for the analytical predictions. Direct publisher-page retrieval was recorded on 2026-10-09; profile summarizes the accessible record and does not claim independent review of inaccessible full text.
If only an abstract or metadata was available, the profile is limited to claims supported there. A paper's paywall does not change its evidentiary status, but it limits what we can substantiate from accessible text.
