The World in the Model

Mary S. Morgan, Fellow of the British Academy and Overseas Fellow of the Royal Dutch Academy of Arts and Sciences, is Professor of History and Philosophy of Economics at the London School of Economics and University of Amsterdam. She has published on a range of topics in the history and philosophy of economics: from statistics to experiments to narrative, and from nineteenth-century Social Darwinism to game theory in the Cold War. Her previous books include The History of Econometric Ideas (Cambridge University Press, 1990) and Models as Mediators (Cambridge University Press, 1999, co-edited with Margaret Morrison). She has also edited collections on measurement, policy making with models and the development of probability thinking. In the broader sphere, the collection of essays How Well Do Facts Travel? (Cambridge University Press, 2011, co-edited with Peter Howlett) marks the conclusion of a major interdisciplinary team project on evidence in the sciences and humanities. Professor Morgan is currently engaged in the project 'Re-thinking Case Studies Across the Social Sciences' as a British Academy-Wolfson Research Professor, this year as a Davis Center Fellow at Princeton University.

'This well-informed and beautifully written series of case studies offers the best analysis to date of how economists work with models. It should help all economists think more deeply about what they do and give others insights into the way economic reasoning works.' Roger Backhouse, University of Birmingham
