Journal article: In this column, Jean-Pierre Danthine, a co-author of "Making Sense of Subsidiarity: How Much Centralization for Europe?", revisits the report nearly 25 years on from its publication. He examines the main themes of the report and shows how such areas as centralisation/decentralisation, subsidiarity, and macroeconomic stabilisation have played out over the years since the report was published. He concludes that the report was both prescient and, at the same time, represents a view from the past of the 'road not taken'.
