The paper presents a model of a software monopolist who benefits from a lagged network externality arising from consumers' feedback through the so-called bug-fixing effect. That is, the software producer is able to correct errors in the software code detected by previous users, improving her...

This paper investigates strategic interactions between a private highway operator anda private transit operator who uses the same highway for its services. Heterogeneity oftravellers is taken into account by considering a continuous distribution of values of time.Demand elasticity arises from...

This paper studies the problem of a monopolist who sells a network good through a price posting scheme. The scheme posts a price of every possible allocation for each buyer, who are then asked to report their private information to the seller. The seller then implements the allocation based on...

We study optimal experimentation by a monopolistic platform in a two-sided market framework. The platform provider faces uncertainty about the strength of the externality each side is exerting on the other. It maximizes the expected present value of its profit stream in a continuous-time...

We investigate the bearings of network externalities on product quality improvements requiring costly R&D investments. The model considers the dynamic behaviour of a monopolist alternatively maximising profits or social welfare. On the one hand, we confirm much of the acquired wisdom from the...

Die Wirkung des Wettbewerbs von Medienunternehmen auf das Marktergebnis ist in einigen einschlägigen Modellen durchaus ambivalent. So haben - erstens - monopolistische Anbieter unter Umständen höhere Anreize, ein breitgefächertes Angebot zu erstellen. Zweitens ist das typische Kalkül der...

This paper analyzes pricing decisions and competition in network markets, assuming that groups of consumers can coordinate their choices when it is in their interest, if coordination does not require communication. It is shown that multiple asymmetric networks can coexist in equilibrium. A...
