Abstract
This study tests the asymmetric effect of user-generated, open-ended online reviews on online shopping behaviour (intention-to-buy, intention-to-recommend, and willingness-to-pay). Three online experiments involving manipulating the valence intensity of online reviews for hotels, books, and running shoes (overall customer sample of n=818) provide empirical support for the proposed relationship. The valence intensity of online reviews moderates the effect of online reviews on purchase intentions. In other words, a significant change in online shopping behaviour was found for positive medium and strong reviews, but not for negative ones. Based on these findings, managers should encourage customers to share their positive consumption-related experiences by offering strong arguments that will convince other customers.
