This column introduces a new series – CEPR Flashbacks – which highlights past CEPR reports that are relevant to today’s challenges. In many cases, the analysis is highly pertinent to today’s policy questions, while in others the reports provide useful context on how leading thinkers approached similar problems in the past. The first CEPR Flashback highlights a 1995 report, “Flexible Integration”, which suggested a solution to the problem that EU leaders are tackling in their current reflection on the Future of Europe.
