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...

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...

Durant les années 1930, Hicks cherche à comprendre la crise à laquelle l’économie mondiale est confrontée. Mais à la différence de la plupart des économistes de l’époque, il tente de se représenter théoriquement la situation dans un cadre d’équilibre général walrassien. Le...

Our paper studies two attempts at integrating unemployment in macroeconomics. The first, due to Diamond, consists in a search model exhibiting multiple equilibria. The second is due to Andolfatto and Merz who, more or less simultaneously, were able to integrate the matching function in RBC...

L'article applique à la micro-économie une distinction classique en philosophie du langage, celle des propositions analytiques et synthétiques. Un article ultérieur la rapprochera de la distinction épistémologique des connaissances a priori et a posteriori. On commence par reprendre les...

Un article précédent étudiait la distinction sémantique de l'analytique et du synthétique et l'appliquait à la micro-économie; celui-ci confronte les propositions micro-économiques fondamentales à la distinction épistémologique de l'a priori et de l'a posteriori (ou de l'empirique),...

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...
