INFORMATION EXCHANGE THROUGH NON-BINDING ADVANCE AbstractWe study the welfare effects of non-binding advance price announcements. Applying a differentiated Bertrand model with horizontal products and asymmetric information, we find that such announcements can help firms to gain information on each other thereby allowing them to achieve higher profits. However, our results also show that the overall welfare effects of such announcements in a context of heterogeneous products are not as clear-cut as previous research in a homogeneous products framework has suggested. We conclude that -although non-binding advance price announcements may raise competition concerns -in many settings, their positive effects are likely to outweigh the potential detrimental effects on welfare.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
