In this paper, we consider a T-stage linear model of Stackelberg oligopoly. First, we show geometrically and analytically that under the two conditions of linear market demand and identical constant marginal costs, the T-stage Stackelberg model reduces to a model where T oligopolies exploit...

In this paper, we consider a hierarchical oligopoly model, in which firms compete on quantities of an homogeneous product. We provide a proof and an interpretation that under the three necessary and sufficient conditions of linear aggregate demand, constant and identical marginal costs, the...

We consider a real business cycle model with a productive externality and an aggregate non- convex technology set µa la Benhabib and Farmer embodying capacity utilization, which exhibits indeterminacy of the steady state and multiplicity of deterministic equilibria under plausible values of the...

This paper aims at building up a simple model of a decentralized monetary economy with Keynesian unemployment. The existence of involuntary unemployment is based on the organization of trades. Money plays a critical role in coordinating decentralized transactions in equilibrium and in...

In this note, we consider a multisector macroeconomic model under oligopolistic competition. We analyze the effect of an increase of the number of sectors on equilibrium price and on allocations, when the number of oligopolits of each type is constant. We also show that a tax policy has more...

In this note, we address the problem of determining which conjectural variations general equilibria are consistent in strategic multilateral exchange. We therefore consider expectations in a simple conjectural general equilibrium model of a pure exchange economy under strategic interactions....

This paper explores the rationale of price-taking and price-making behaviours in the context of Walrasian and Cournotian pure exchange economies. Beside the influence of the number of agents, we underline the role of the structure of preferences. Through three equilibrium variations of the same...
