Abstract

[eng] The paper first takes note of the difficulties met by Joan Robinson and her partisans and critics when attempting to pull together the post-Keynesian short-period approach and the classical long-period approach. In attempting to reach a post-classical synthesis, it is proposed to start from a Kaleckian model of growth and distribution, the price system of which would rely on the full cost approach, more precisely the target return principle, computed on the basis of a normal rate of capacity utilization. The second part of the paper describes such a model with excess capacities, while the third part deals with the analysis of the traverse from one steady-state to another within a two- sector framework. Dynamic stability issues and reproportionning are also dealt with. In conclusion it is noted that while some mechanisms may support the claims of those who argue that long-period analysis must be conducted on the basis of fully adjusted positions — linked to normal rates of utilization — this does not imply that the results and causations of the Keynesian/Kaleckian approach, along with its principle of effective demand, must be discarded in long run analysis. This conclusion arises as a consequence of the phenomenon of hysteresis, which transforms the normal rate of capacity utilization into a variable which itself is endogenous. [fre] Ce texte évoque en premier lieu les difficultés rencontrées par Joan Robinson et ses partisans et critiques pour intégrer l'approche post- keynésienne par la courte période et l'approche classique par la longue période. Pour tenter de parvenir à une synthèse post-classique, il est suggéré de partir d'un modèle kaleckien de croissance et de répartition, dont le système de prix reposerait sur le principe du coût complet, plus précisément sur le principe du taux de rendement cible calculé à un taux d'utilisation normal. Un tel modèle est élaboré dans la seconde partie du texte, tandis que sa troisième partie examine le problème de la traverse de ce modèle avec capacités excédentaires, d'un régime permanent à un autre. Les problèmes de stabilité dynamique et de réaménagement de la structure productive sont notamment étudiés. On conclura en notant que si certains mécanismes peuvent donner raison à ceux des économistes classiques qui affirment que l'analyse de longue période doit se situer dans le cadre de positions pleinement ajustées, à taux d'utilisation normal, on ne peut rejeter pour autant les résultats et les causalités invoquées par l'approche keynéso-kaleckienne et son principe de la demande effective. Ceci est dû au phénomène de l'hystérèse, qui fait du taux d'utilisation normal une variable elle-même endogène.
