Abstract

Les théories du cycle d'affaires, telles qu'elles émergent au début des années 1950, mettent l'accent sur les problèmes de coordination, et plus précisément sur les effets des comportements d'investissement hors de l'équilibre. Les nouvelles théories, qui se sont développées à partir des années 1970, sont basées sur la méthode de l'équilibre et mettent l'accent sur les propriétés de la fonction d'utilité, de la fonction de production ou de la structure d'information ex ante. Elles constituent un véritable défi pour les « vieilles » théories, mais elles ne les rendent pas obsolètes, dans la mesure où elles font défaut sur un point crucial qui est d'expliquer la nature d'une dynamique multi-phases (ou multi-regimes).
