Abstract

Dans cet article, une évaluation critique des modèles d'équilibre général dynamique stochastique, qui constituent le fondement théorique des politiques mises en œuvre par les banques centrale, est le point de départ pour reconsidérer la nature des fluctuations et produire des arguments en faveur d'une approche « hors de l'équilibre ». Cette dernière met l'accent sur les distorsions de la capacité productive induites par tout changement structurel et montre pourquoi et comment l'incohérence temporelle entre les phases de construction et d'utilisation de la capacité productive a une contrepartie monétaire et financière qui peut engendrer une instabilité globale. Elle appelle une révision des objectifs de la politique monétaire et un nouveau Policy mix.
