Newspapers’ market shares and the theory of the circulation spiral

We consider a model of daily newspapers’ competition to test the validiity of the so called “theory of the circulation spiral”. According to it, the interaction between the newspapers and the advertising markets drives the newspaper with the smaller readership into a vicious circle, finally leading it to death. In a model with two newspapers, we show that, contrary to this conjecture, the dynamics envisaged by the proposes of the theory, does not always lead to the elimination of one of them.

L'industrie des médias à l'ère numérique

Les médias changent de paradigme. La révolution numérique bouleverse les règles du jeu et les positions de force des principaux acteurs. La possibilité de consommer de la musique, des journaux en ligne et des programmes audiovisuels grâce à une simple ligne téléphonique oblige à reconsidérer l'économie des médias traditionnels. Cet ouvrage entièrement refondu fournit les principales clés pour comprendre la nouvelle économie des médias et du numérique. À partir des concepts fondamentaux (bien publics, marchés à deux versants, effets de réseaux), il analyse le nouvel environnement face aux nouveaux enjeux et défis de ce secteur (gratuité, piratage, interactivité, nouveaux acteurs), étudie les principaux secteurs d'activité des médias (télévision, presse écrite, Internet et publicité) et analyse le rôle de l'État et de la régulation via notamment les modalités de l'intervention

Programming and advertising competition in the broadcasting industry

We analyze competition between two private television channels that derive their profits from advertising receipts. These profits are shown to be proportional to total population advertising attendance. The channels play a sequential game in which they first select their profiles (program mixes) and then their advertising ratios. We show that these ratios play the same role as prices in usual horizontal differentiation models. We prove that whenever ads' interruptions are costly for viewers the program mixes of the channels never converge but that the niche strategies are less effective and that the channel "profiles" are closer as advertising aversion becomes stronger
