Mary Morgan is the Albert O. Hirschman Professor of History and Philosophy of Economics at the LSE. Her research has addressed the practical side of how economists do economics: how do models, measurements, observation, experiments, etc. actually work, and how have these changed over the last century? Her most recent books include The World in the Model and How Well Do Facts Travel? Professor Morgan has received many research grants, honours and awards, and is Vice-President of the British Academy and an Overseas Fellow of the Royal Dutch Academy of Arts and Sciences. She is currently working on projects on poverty measurement, on how economics gets used to change things in the world, and on the ways that narrative forms of explanation are used in the sciences.
