In this paper we model a situation of competition between two editors who are rivals in both the newpapers' and advertising industries.. To identify the consequences of this competition, we analyse a two-period sequential game whose players are the editors each selling a differentiated...

Generally, economists interested in network effects analyse these effects when the consumption externality created by the demand for the good is produced inside the industry itself. But it can be conceived that network effects take place from one industry to another. This happens when the...

We analyse the rivalry between two TV-channels competing both on the market for audience and the market for advertising. We identify the nature of TV-programs emerging from this competition, and the quantity of advertising that TV-viewers will have to attend at equilibrium. Finally, we examine...

The present note first provides an alternative formulation of the Cancian, Bills and Bergström (1995)- problem which discards the non-existence difficulty and consequently allows to consider some extensions of the TV-newscast scheduling game. The extension we consider consists in assuming that...

We propose a model representing a newspaper producer supplying a product which can be acquired by the readers either every day per one unit at a time, or by subscription. The population of potential buyers is differentiated according to the frequency at which they want to read the newspaper....
