Abstract

L'objet de cet article est de proposer une lecture de l'évolution des faits et des idées économiques dans la perspective de montrer que les vieilles idées resurgissent sous de nouveaux atours, au point d'en cacher les lacunes et de rendre les crises, non seulement difficiles à prévoir, mais même à imaginer. Vouloir incriminer la seule finance et l'incapacité des économistes à en cerner les véritables arcanes pour les expliquer ne saurait suffire, pas plus d'ailleurs que ne le saurait la tentative d'avoir une macroéconomie des temps de crise différente de celle des temps calmes. Les crises ne viennent pas de nulle part. Elles sont le fruit d'une longue maturation dont les clés sont difficilement perceptibles par temps calme, mais existent bel et bien. La principale leçon de cette courte histoire est, sans doute, qu'il faut aller vers une macroéconomie réunifiée, permettant d'articuler court et long terme et de mettre en scène des agents hétérogènes.
