Éminent collègue dans les domaines de la théorie de la décision et de la philosophie économique, Philippe Mongin, directeur de recherche au CNRS et professeur à HEC, s’est éteint le 5 août dernier.
It is with an immense sadness that the French-speaking community of philosophers of economics and historians of economic thought learned that Philippe Mongin had passed away after a long medical fight on August 5, 2020.
Born in 1950, Philippe had always been an extremely brilliant student. He entered the Literature and Philosophy department of the prestigious French Ecole Normale Supérieure in 1969. In 1973 he was successful at the “agrégation” in Philosophy, and begun a Ph.D. thesis in Social Sciences at the Ecole des Hautes Etudes en Sciences Sociales (EHESS) under Raymond Aron, on Marx’s 1857 and 1858 manuscripts - the Grundrisse: La critique de l'économie politique dans les Grundrisse de Karl Marx.
Visiting scholar at King’s College, Cambridge, between 1975 and 1978, he was close to Frank Hahn and became interested in recent macro and microeconomic theory. Back to France, he worked in the 1980s on Herbert Simon’s notion of bounded rationality (see his « Simon, Stigler et les théories de la rationalité limitée », Social Science Information, 1986). In 1984, he received a new degree in Mathematics and defended a second Ph.D. thesis in Economics.
In the 1990s, following Amartya Sen’s work, he focused on normative economics, more specifically on the subjects of collective preferences under uncertainty (see his « Factoring out the impossibility of logical aggregation », Journal of Economic Theory, 2008), and on John Harsanyi’s reformulation of utilitarianism.
Between 1991 and 1996, he was appointed as invited professor at the University of Louvain-la-Neuve, where he co-authored some work with Claude d’Aspremont on the philosophical foundations of utility theory (see Philippe Mongin and Claude d'Aspremont, « Utility Theory and Ethics », Handbook of Utility Theory, Kluwer, 1998, ch. 10, pp. 371-481), developed some original research in epistemic game theory (see M. Bacharach, L.A. Gérard-Varet, P. Mongin and H. Shin, eds., Epistemic Logic and the Theory of Games and Decisions, Kluwer, 1997) - and met his wife, economist and prominent game theorist Françoise Forges.
After his stay at Louvain, Philippe became member of the THEMA research centre at the University Cergy-Pontoise, where he deepened his research program in normative economics in collaboration with co-authors such as Marc Fleurbaey and Jean-François Laslier (with whom he organised a monthly seminar in the philosophy of economics, « les Midis de l'Economie et de la Philosophie »).
In the 2000s, Philippe turned to a new field of inquiry: judgment aggregation theory (see his « Value Judgments and Value Neutrality in Economics », Economica, 2006), then developed an interest in the relation between game theory and the principle of rationality, and organized the first conference on Analytical Narratives in France. In 2006, he became Professor in Economics and Philosophy at the Ecole des Hautes Études Commerciales (H.E.C.), where he taught until 2015.
Throughout his career, Philippe was often appointed as visiting professor or visiting scholar: at the UQAM (Université du Québec à Montréal) in 1986, 1988, 1992 and 2004; at Duke University, University of California at Riverside, University of Chicago, and Stanford University in 1990; at the LSE in 1995 and from 1999 to 2002; at the University of British Columbia and at the Stanford Institute in Theoretical Economics in 1996; at the University of Graz in 1998; at Johns Hopkins in 2002; at the California Institute of Technology in 2003; at the Centre Walras-Pareto of the University of Lausanne in 2006 and 2007; at the Cowles Foundation and at Boston University in 2006 and 2008; at the International Center for Economic Research (ICER), in Torino, in 2007 and 2008; at Brown University in 2011; at the Australian National University in 2013; at the Wissenschaftskolleg zu Berlin in 2015-2016; and at the Max Planck Institut für Wissenschaftsgeschichte (MPIWG) in Berlin in 2016.
He gave plenary and keynote lectures at numerous international conferences (including the 2002 ESHET conference in Graz), and was member of many editorial boards, for: the Journal of Economic Methodology, the Revue économique, the Revue de philosophie économique, Social Science Information / Information sur les Sciences Sociales, Economics and Philosophy, and Theory and Decision.
He also wrote two reports for the "Conseil d’analyse économique": on the project of a solidarity labor income (revenu de solidarité active, RSA) in 2008; and on the links between major risks and public action in 2013.
He was awarded prestigious distinctions: the two French national orders, the Ordre National du Mérite in 1995, and the Ordre National de la Légion d'honneur in 2004; and, recently, in 2019, the Maurice Allais prize in Economics, and the Grammaticakis-Neumann prize of the French Académie des sciences morales et politiques.
Philippe was brilliant, innovative and always extremely elegant: we lost both an important thinker and a friend.
