Cet article étend l’analyse des jeux stratégiques de marché au modèle à générations imbriquées? Nous considérons une économie avec un bien et de la monnaie de crédit où les stratégies des agents sont du type “achat ou vente”. Nous montrons que l’existence d’un équilibre...

Have new classicists invented market clearing or have they rehabilited it ? This is the question addressed in the present paper. It is generally agreed that market clearing underpins Walrasian theory, so my exploration is limited to the question of whether this is also true for Marshallian...

The label “Keynes-Negishi equiibria” is attached here to equilibria in a monetary economy with imperfectly competitive product and labor markets where business firms and labor unions hold demand perceptions with kinks - as posited in Negishi’s 1979 book Microeconomic Foundations of...

This article examines the question of which institutional assumptions underly competitive general equilibrium theory. Extending Walra’s terminology, the organization of trade hypothesis typical of this theory is called tâtonnement. Its components and its working principles are analysed...

In this paper, we challenge the usual argument which says that competition is a fair mechanism because it ranks individuals according to their relative preferences between effort and leisure. This argument, we claim, is very insuficient as a justification of fairness in competiton, and we show...

The aim of this article is to assess Friedman’s claim, put forward in his 1949 article on the Marshallian demand curve, that there is a methodological divide between the Marshallian and Walrasian approaches. Friedman’s argument will be critically examined and compared with the views he...

The consequences of imposing a minimum real income are studied within the framework of a general equilibrium model in which unemployment is compensated by transfers. With a disaggregated labor market, the equilibrium distribution of employment and real wages is characterized, depending on th...

Hicks is renown for having introduced the temporary equilibrium framework in his book Value and Capital. Subsequently, however, he partially recanted this framework by rejecting the market clearing idea while still keeping the week device. The aim of this paper is to assess whether this change...

We analyse the consequences of a change of the characteristics of goods due to new information on the equilibrium of a pure exchange economy with n goods and m agents. Some changes of the characteristics of goods à la Lancaster have a positive effect on utility. In the general competitive...

In this note the decision problem of a strategic firm in a general equilibrium setting is analyzed. It is shown that a problem of unanimity arises when such a firm has many shareholders, an that a well known criterion used in the case of market incompleteness can be quite interestingly...
