Taste of Free Lunch: The Impact of Free Product Disclosure on Review Dynamics

Does a "free lunch" really exist? Some online shopping platforms let consumers disclose if they received products for free or at a discount when writing reviews. Although these reviews for free products are not the majority, they can energize online communities where reviews are limited. The lack of objectivity in free product reviews can trigger self-regulation within online communities, prompting more users to provide fair feedback. Voluntary disclosure policies can effectively boost the number of reviews at a lower cost than hiring experts to write positive reviews.
