This paper is about limit pricing under complete information and endogenous market demands. If pre-entry and post-entry market demands are correlated, then limit pricing can be an equilibrium strategy under complete information without government intervention. Furthermore, with government...

We consider some two dynamic models of entry in mobile telephony, with and without strategic pricing, and taking into account market penetration at entry, locked-in consumers and tariff-mediated network externalities. We show that on/off-net differentials may reduce the possibility of entry if...

Acess to both a local and a global network is needed in order to get complete connection to the Internet. The purpose of this article is to examine the interplay between these two networks and how it affects the domestic plublic policy towards a domestic provider of local access.

Airlines frequently use code-share agreements allowing them to market seats on flights operated by partner airlines. Current studies argue that with complementary networks this generates positive welfare effects because fares for interline passengers who rely on the service of multiple airlines...

We construct a model for differentiated Cournot competition between service-based and infrastructure-based firms, out of which one infrastructure-based firm (the incumbent) supplies to the service-based firms. We seek for and compare the socially optimal and the incumbent’s profit maximizing...

In this paper, we analyze the effect of access regulation and retail price regulation of PSTN networks on the adoption of a new technology in the form of VoIP. The introduction of packet-switched telephony in the form of VoIP raises concerns about current regulatory practice of access,...

Whenever you phone your mother, switch on the light, or buy health insurance you purchase a service or product from a chain of vertically related industries. Providers of these products or services need access to a telecommunications network, an electricity network or to health care...

In this paper we provide a theoretical foundation for the Porter hypothesis in a context of quality competition. We use a duopoly model of vertical product differentiation where firms simultaneously choose the environmental quality of the good they produce (which can be either high or low) and,...

We study the relationship between regulatory regimes and pharmaceutical firms’ pricing strategies using a unique policy experiment from Norway, which in 2003 introduced a reference price (RP) system called “index pricing” for a sub-sample of off-patent pharmaceuticals, replacing the...

We consider a therapeutic market with potentially three pharmaceutical firms. Two of the firms offer horizontally differentiated brand-name drugs. One of the brand-name drugs is a new treatment under patent protection that will be introduced if the profits are sufficient to cover the entry...
