Marion Fourcade is an Associate Professor of Sociology at UC Berkeley (on leave 2012-2013) and currently a director of the Max Planck-Sciences Po Center on Coping with Instability in Market Societies and a professor of sociology at Sciences Po, Paris. A comparative sociologist by training and taste, she is interested in variations in economic and political knowledge and practice across nations. Her first book, Economists and Societies (Princeton University Press 2009), explored the distinctive character of the discipline and profession of economics in three countries. She is now working on a second book, tentatively called Measure for Measure: Social Ontologies of Classification, which examines the cultural and institutional logic of what we may call “national classificatory styles” across a range of empirical domains. Current studies for this book include environmental valuation, the digitization of books and the classification of wines in France and the United States. Other ongoing research focuses on the role of the credit market in social stratification (with Kieran Healy); the comparative study of political organization (with Evan Schofer and Brian Lande); the microsociology of courtroom exchanges (with Roi Livne); and the role of business schools in the neoliberal turn (with Rakesh Khurana).
