In this paper we propose an example of successive oligopolies where the downstream firms share the same decreasing returns technology of the Cobb-Douglas type. We stress the differences between the conclusions obtained under this assumption and those resulting from the traditional example...

This paper analyses successive markets where the intra-market linkage depends on the technology used to produce the final output. We investigate entry of new firms, when entry obtains by expanding the economy as well as collusive agreements between firms. We highlight the differentiated effects...

In this paper we analyze how the technology used by downstream firms can influence input and output market prices. We show via an example that both these prices increase under a decreasing returns technology while the countrary holds when the technology is constant.

This paper investigates how an incumbent monopolistic can weaken potential rivals or deter entry in the output market by manipulating the access of these rivals in the input market. We analyze two polar cases. In the first one, the input market is assumed to be competitive with the input being...

We propose a non-cooperative game in order to emphasize the srategic rationale in shaping the distribution system. Compared with the received literature, we let manufacturers select which retailer(s) will market their respective brand. This, together with retailers possibly being multi-product...

We model environmental interaction among countries as a policy game where government in each country use quotas or taxes as a strategy variables. The environmental policy has a triple role to play : targeting domestic emission, providing strategic advantages for domestic firms and targeting...

L'objet de cet article est de relier les préférences des consommateurs pour les produits verts, les décisions d'investissement dans la recherche et le développement d'une industrie polluante et l'optimalité de la taxation de ses émissions polluantes dans le cadre des jeux en trois étapes...

Nous analysons une politique environnementale menée de façon unilatérale par un Pays Développé, destinée à lutter contre une pollution globale. Dans un cadre de concurrence internationale, nous étudions les conséquences d'une telle politique sur la répartition géographique des...

Le présent papier s'articule autour des problèmes environnementaux globaux, et se propose de lier les négociations internationales au comportement de précaution. Cela nous conduit à montrer que le comportement de précaution peut aussi bien survenir à la suite d'un échec des négociations...

The paper discusses the relation between the justly famous Hotelling’s [1929] paper on stability in competition and the corresponding passages of the often ignored Launhardt’s [1885] book, devoted to mathematical economics. Launhardt is sometimes credited for the anticipation of...
