Abstract

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 newspaper, like newspapers of different political content.We characterise the equilibria and explore how they depend on the number of ad-avoiders and ad-lovers, and on the intensity of readers' attraction or repulsion feelings for advertising. Our main finding is that equilibria are often observed in the sequential game, at which one of the editors prevents the entry of his rival and fully monopolises both the press and advertising markets.
