In the framework of symmetric Cournot oligopoly, this paper provides two minimal sets of assumptions on the demand and cost functions that imply respectively that, as the number of firms increases, the minimal and maximal equilibria lead to (i) decreasing industry price and increasing or...

I apply three noncooperative models of coalition formation to a Cournot olygopoly. In each model, each firm has to choose the coalition it wants to belong to. But each of those models is characterised by a different assumption that defines what happens to a coalition from which one or more...

Consider an oligopolistic industry where demand uncertainty resolves after at least one firm has engaged in production. Those firms who produce first behave as simultaneous leaders (co-leaders), whilst those who produce after demand becomes observable will be followers. Each follower simply...

In an oligopoly supergame, firms face an obvious technological constraint: the positivity of their production quantities. WE show that Lambson's (1987) result on "security-level punishment", that the single-period punishment makes the firm's discounted participation condition just bind, holds...

This paper considers a three-stage game of a differentiated oligopoly: firms first make their entry decisions, then they choose production technologies and in the third stage of the game they decide product prices. The technology choice can be understood as selecting a technology from a pool of...

This paper studies the effects of 'price-matching' policies in the Bertrand oligopoly model. If one or more consumers incur enforcement costs to utilize price-matching clauses, the unique equilibrium outcome is the competitive one.

We analyze the strategic pricing and informative advertising decisions made by firms in duopolistic contexts. We show that whether the products are substitutes or complements, these exist strategic settings in which firms keep potential consumers uninformed about their products even if...

This paper considers an incumbent firm that is faced with a potential entrant in a vertically differentiated market. It demonstrates than an incumbent firm cannot prevent entry through product proliferation because of a commitment problem.

We study in this paper how the technological flexibility choices and equilibrium configurations depend first on the industry characteristics (demand function and cost parameters specific to the multiproduct flexible technology and to the product dedicated technologies) and, second, on the...
