Recent literature shows that learning in oligopoly games might in the long run result in the Cournot or in the Walras equilibrium. Which outcome is achieved seems to depend on the underlying learning dynamics. This paper analyzes the forces behind the learning mechanisms determining the long run outcome. Apart from the fact that there is a difference between social and individual learning, the ...

In standardWalrasian macro-finance models, pecuniary externalities such as fire sales lead to overinvestment in illiquid assets or underprovision of liquidity. We investigate whether imperfect competition (Cournot) improves welfare through internalizing the externality and find that this is far from guaranteed. In a standard model of liquidity shocks, when liquidity is sufficiently scarce, Cour...

We examine the impact of abatement taxes on the pollution level in a duopoly framework with endogenous market structure. We demonstrate that an increase in abatement taxes could trigger a regime-switch from joint ventures to Cournot competition, causing the pollution level to increase. Moreover, abatement taxes can implement the first best outcome if and only if the industry is not too pollutin...

This paper examines airline competition through an empirical specification of a demand and pricing equation system. The system is estimated for the Spanish airline market using a simultaneous procedure. The suitability of the Cournot assumption is tested in a competitive scenario characterized by an asymmetric oligopoly with capacity constraints. In addition, the degree of density economies is ...

We develop a model of wage bargaining with private information in a duopoly. We investigate how product differentiation and market competition (Bertrand vs. Cournot competition) affect wages and strikes. If bargaining takes place at the industry-level, then both the wage outcome and the strike activity do not depend on the degree of product differentiation whatever the type of market competitio...
