We prove the existence of symmetric pure Cournot equilibria with heterogeneous goods under the following condition: each firm reacts to a rise in competirors output in such a way that its market price does not rise. This condition is not related to wether goods are strategic substitutes or...

This note provides sufficient conditions for immediate agreement in an extensive form model of interdependent bilateral bargaining. The model is suggested by Björnerstedt and Stennek (2006) as a work horse for studying bilateral oligopoly. The key feature of this model is that the firms are...

This paper focuses on incentives to invest in research and development (R&D) in vertically related markets. In a bilateral duopoly setup, we consider how process R&D incentives of the firms in both upstream and downstream market depend on the intensity of simultaneous interbrand and intrabrand...

In a bilateral oligopoly where strategic buyers source a good from competing suppliers over time, buyers often have an incentive to sustain competition while suppliers benefit from excluding rival suppliers. We model this situation as a two period asymmetric cost Bertrand duopoly, where in the...

In many intermediate goods markets buyers and sellers both have market power. Contracts are usually long-term and negotiated bilaterally, codifying many elements in addition to price. We model such bilateral oligopolies as a set of simultaneous Rubinstein-Ståhl bargainings over contracts...

This paper provides a conceptual framework of multilateral bargaining in a bilaterally oligopolistic industry to analyze the motivations for horizontal mergers, technology choice, and their welfare implications. We first analyze the implication of market structure for the distribution of...

Bilateral oligopoly is a simple model of exchange in which a finite set of sellers seek to exchange the goods they are endowed with for money with a finite set of buyers, and no price-taking assumptions are imposed. If trade takes place via a strategic market game bilateral oligopoly can be...

L'article montre, contrairement au résultat classique de la littérature sur les relations verticales (avec problème d'engagement sur les contrats, en amont) que le profit d'un fournisseur peut augmenter avec le nombre de distributeurs s'il n'est pas un monopole, mais est concurrencé par un...
