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...

This paper first introduces an approach relying on market games to examine how successive oligopolies do operate between downstream and upstream markets. This approach is then compared with the traditional analysis of oligopolistic interaction in successive markets. The market outcomes resulting...

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...

In this paper, we investigate dynamic price competition when firms strategically interact in two distinct but interrelated markets: a primary market and an aftermarket, where indirect network effects arise. We set up a differential game of two-dimensional price competition and we conclude that...

The aim of this paper is to develop a dynamic model of migrations, in which migration is driven by size asymmetries between countries and by the relative preferences of consumers between private consumption and consumption of public goods. The dynamic trajectories heavily depend on the degree of...

In this paper we address the following question: is it more profitable, for an entrant in a differentiated market, to acquire an existing firm than to compete? We illustrate the answer by considering competition in the banking sector.

We analyze the competition between two newspapers in a vertical differentiation model where the qualities of the journals are determined endogenously in the first stage of the game. We show that when the advertising revenues per reader increase there is a critical value above which the quality...

We consider a situation of duopolistic competition in the press industry, involving two editors competing in both the newspapers' and advertising markets. The population of readers in this market is differentiated in terms of their attitudes toward advertising; some of them are assumed to be...
