The Symposium was inspired by the critical light the global financial crisis and its aftermath threw on the capabilities and limitations of established thinking in macroeconomics. Around 60 researchers attended, many of high international repute, reflecting a wide spectrum of approaches to macroeconomic research and teaching. The presenters and discussants, all leading figures in their field, generated lively and mostly good-natured open-floor discussions casting invaluable light on present issues and debates. The symposium clarified that many crucial macroeconomic problems remain and that support for theoretical, empirical and policy related research is essential. It also revealed a diversity of approaches with promise to challenge the current monolithic view.
