Cet article intègre la question environnementale à l’étude de secteurs caractérisés par des producteurs de bien vierge avec un pouvoir de marché, confrontés à un secteur du recyclage. On utilise un modèle où la production de bien vierge par un monopole est polluante, contrairement à...

Digital platforms operate in multisided markets providing services through the internet to two or more distinct groups of users, between which there are indirect network effects. Direct network effects are frequently present within each group. Therefore, online platforms usually present both...

Negotiations regularly take place on the business-to-business side of two-sided markets. However, little is known about the consequences of these negotiations on a platform's design, pricing, participation, and welfare. In this paper, we propose a model where platforms choose between the...

This paper presents a theoretical model of two-sided markets with both positive inter-side externalities and negative intra-side externalities. It analyzes the net impact of negative intra-side externalities on platform prices, demands and profits in three scenarios: (i) monopoly platforms, (ii)...

I develop a general theory of monopoly pricing of networks. Platforms use insulating tariffs to avoid coordination failure, implementing any desired allocation. Profit-maximization distorts in the spirit of Spence (1975) by internalizing only network externalities to marginal users. Thus the...

Unaccountable power at any layer of online life can stifle innovation elsewhere. Dominant search engines rightly worry that carriers will use their control of the physical layer of internet infrastructure to pick winners among content and application providers. Though they advocate net...

Technological advances, because they have radically lowered the costs of creating and distributing expressive works, have shaken the foundations of copyright policy. Once, those who held copyrights in sound recordings, movies, television shows, magazines, and the like could safely assume that...

Piracy has been a major problem for perpetually licensed software. Usage-based licensing architecture such as pay-per-use or software-as-a-service can offer technology-based protection against piracy. We provide an analytical framework to examine the economic implications of pay-per-use versus...

This article considers how electricity utility regulators should treat infrastructure investments related to electric vehicles. It begins by analyzing investments using traditional utility regulatory policy norms. Next, the article analyzes whether utility regulators should broaden their...

We consider a model where a monopolist can profile consumers in order to price discriminate among them, and consumers can take costly actions to protect their identities and make the profiling technology less effective. A novel aspect of the model consists in the profiling technology: the signal...
