'Snowdon and Vane's book is extremely welcome. Indeed the authors examine, compare, and evaluate the evolution of the major rival stories comprising contemporary macroeconomic thought, but they also trace the development and interaction of key events and ideas as they occurred in the last century. Interviews with leading economists, one or two at the end of each chapter, also greatly help to shed light on this complexity. . . In sum, this is book which is very difficult to put down.' - Alessio Moneta, Journal of the History of Economic Thought
