RIGIDITÉS SALARIALES ET CHÔMAGE. LES FRONTIÈRES CLASSIQUES DU PROGRAMME NÉO-KEYNÉSIEN ÉTAIENT-ELLES TRACÉES?

This article underlines the restrictive perspective of the neo-keynesian research program of "microdoundations of unemployment", compared to the keynesian project of a general theory which would marginalize the classical cases. This neo-keynesian program has first restricted the interpretation of the General Theory, adopting the hypothesis of nominal rigidity of wages. Secondly, it did reject this hypothesis, which could not be supported by strong microfoundations and has progressively accepted the rational expectations hypothesis. In the models of general equilibrium with imperfect competition, neokeynesians have [mally adopted a theory of structural unemployment with classical properties.
