This paper studies the incentives for multiproduct duopolists to sell their products as a bundle. It is shown that contrary to the monopoly case bundling may reduce profits and increase consumer rent. This is the case if consumers' reservation values are negatively correlated. The reason is that...

This paper analyses a two-sided market in which two platforms compete against each other. One side, the advertisers, exerts a negative externality on the ther side, the users. It is shown that if platforms can charge advertisers only, a higher degree of competition for users can lead to higher...

This paper develops a model of successive oligopolies with endogenous market entry, allowing for varying degrees of product differentiation and entry costs in both markets. Our analysis shows that the downstream conditions dominate the overall profitability of the two-tier structure while the...

We investigate how the structure of the distribution channel affects tacit collusion between manufacturers. When selling through a common retailer, we find - in contrast to the conventional understanding of tacit collusion that firms act to maximize industry profits - that colluding...

For many products, platforms enable sellers to transact with buyers. We show that the competitive conditions among sellers shape the market structure in platform industries. If product market competition is tough, sellers avoid competitors by joining different platforms. This allows platforms to...

Two-sided market models in which platforms compete in two-part tariffs, i.e., a subscription and a per-transaction fee, are often plagued by a continuum of equilibria. This paper incorporates heterogeneous trading behavior of agents into the existing framework. We show that this natural and...

We consider a market with two symmetric firms and two asymmetric consumer groups. Firms send advertising messages which inform consumers about the existence and the price of their product (Butters, 1977). Targeting a specific consumer is imperfect as with some probability the consumer is not...
