Un modèle macroéconomique dans la tradition de Keynes et Kalecki

[fre] par rapport à l'équilibre de court terme, indique néanmoins qu'un comportement cyclique de l'économie (c'est-à-dire une alternance des régimes de déséquilibre) engendre nécessairement la convergence. [eng] This article is a generalization of recent work of J. Cartelier (1990), who develops a disequilibrium macroeconomic model that escapes from the paradoxes of general equilibrium. Money is indeed present in the exchanges and the unfolding of transactions informs the agents about the nature of disequilibrium, modifies their behavior and determines the economy's path. This generates complex dynamics as a succession of disequilibrium regimes. Nothing ensures the convergence of the economy towards" equilibrium" and this one is never a priori computable. The analyses of particular dynamics, expressed in terms of the gap with respect to the short term trajectory, indicates that a cyclic behavior generates necessarily convergence.
