In this paper, we study how the presence of a news aggregator affects competition among (horizontally differentiated) newspapers in the Internet. For this purpose, we build a model of multiple issues which allows each newspaper to choose quality on each issue. Our model provides a micro...

This paper investigates the patent licensing networks formed by competing firms. Assuming that licensing agreements can involve the payment of fixed fees only and that firms compete à la Cournot, we show that the complete network is always bilaterally efficient and that the monopoly network is...

We study a retail benchmarking approach to determine access prices for interconnected networks. Instead of considering fixed access charges as in the existing literature, we study access pricing rules that determine the access price that network i pays to network j as a linear function of the...

We study how access pricing affects network competition when consumers' subscription demand is elastic and networks compete with non-linear prices and can use termination-based price discrimination. In the case of a fixed per minute termination charge, our model generalizes the results of Gans...

We study competition among upstream firms when each of them sells a portfolio of distinct products and the downstream has a limited number of slots (or shelf space). In this situation, we study how bundling affects competition for slots. When the downstream has k number of slots, social...

We study bilateral cross-licensing agreements among N( 2) firms that engage in competition after the licensing phase. It is shown that the most collusive cross-licensing royalty, i.e. the one that allows the industry to achieve the monopoly profit, is sustainable as the outcome of bilaterally...

We study how net neutrality regulations affect high-bandwidth content providers’ investment incentives in quality of services (QoS). We find that the effects crucially depend on network capacity levels. With a limited network capacity, the prioritized delivery services are complements to...
