This study examines the situation in which a monopolist offers freeware as an advertisement for the increase of demand to maximize profit even though the existence of such freeware will reduce the power of the monopolist in the market. This study proves that the successful application of...

Users and suppliers of complementary products on digital platforms routinely face several non-trivial challenges due to an overload of information and fierce competition for attention. As such, effective management and governance mechanisms facilitating network effects and value co-creation with...

Recent progress in information technologies provides sellers with detailed knowledge about consumers' preferences, approaching perfect price discrimination in the limit.We construct a model where consumers with less strategic sophistication than the seller's pricing algorithm face a trade-off...

The digital revolution has allowed sellers to make large assortments of products available to consumers. Recommendation systems have played a central role in this dynamic. At the core of these systems is the use of data and sophisticated algorithms to predict match values between products and...

The aim of this paper is to study the empirical phenomenon of rating bubbles, i.e. clustering on extremely positive values in e-commerce platforms and rating web sites. By means of a field experiment that exogenously manipulates prior ratings for a hotel in an important Italian tourism...

As much as forty percent of social media users have been harassed online, but there is scarce causal evidence of how toxic content impacts user engagement and whether it is contagious. In a pre-registered field experiment, we recruited participants to install a browser extension, and randomly...
