As millions worldwide are addicted to video games, governments and organizations are actively taking measures to curb this trend. Our research suggests that dynamic pricing can help solve the problem of gaming addiction.

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.

The authors have found that pressuring businesses to implement a completely fair pricing system may actually backfire and lead to tacit collusion where consumers will ultimately suffer.
