Dealing with the origins and development of modern approaches to expectations in micro and macroeconomics, this book makes use of primary sources and previously unpublished material from such figures as Hicks, Hawtrey and Hart. 'This book, republished eight years after its fi rst edition, still deserves to be read because it represents a good example of how the history of economics can be shaped and enriched by the passing of time.' - Alessandro Innocenti, University of Siena
