L''économie mondiale va-t-elle connaître les affres de l’enlisement et de la déflation ? Ou s’agit-il plus simplement d’une longue purge après la plus grande bulle boursière de l’histoire ? Cette purge est-elle d’ailleurs achevée ? Quel avenir augure-t-elle pour l’économie mondiale et les marchés financiers ? Plus qu’une correction boursière, il s’agit pour Jean-Pierre Petit d’une rupture économique profonde. Il décrit minutieusement et clairement les enjeux et les implications de cette crise, fruit des illusions et des excès antérieurs et révélatrice des forces et des faiblesses structurelles des grandes économies. Jean-Pierre Petit est directeur de la Recherche économique à Exane.
