Journal article: While the “Trente Glorieuses” have been called into question for the environmental damage they caused, they nevertheless remain a period of exceptional growth characterized by a significant reduction of inequalities in income and wealth. For historians and economists alike, however, the sources of this expansionist phenomenon and its unravelling in the 1970s continues to raise questions. Mixing the qualitative approach much-loved by historians, who study archives for insight into the decision-making process and the quantitative approach characteristic of economists, Éric Monnet’s book offers an interpretation of Banque de France monetary policy at the intersection of two logics. In the present article, three economic historians discuss this interpretation and contextualize its contributions: Nicolas Delalande offers a political vision of state history; Laure Quennouëlle-Corre brings a more institutional and financial perspective to bear; and Laurent Warlouzet examines the question at the Franco-European level. In its conclusion, Éric Monnet offers his own perspective on this survey.
