Summary

The neoliberal utopia of continuous global growth in wealth is now behind us. But this does not mean that capitalism is dead. Its current form is neither genuinely new nor totally unfamiliar, as it is typical of all ages in which the anguishing feeling of a “finite”, bounded and limited world that needs to be grabbed in a hurry dominates. This capitalism is characterised by the privatisation and militarisation of the seas, a monopolistic and rentier “trade” that is exercised within territorial empires, and the appropriation of physical and cyber spaces by gigantic private companies with sovereign prerogatives that dictate their own rhythms. In this essay, Arnaud Orain reveals this “capitalism of finitude” and sheds light on its mechanisms in the three periods in which it flourished: XVIᵉ – XVIIIᵉ century, 1880-1945, 2010 to the present day.

Arnaud Orain, an economist and historian, is director of studies at the École des Hautes Études en Sciences Sociales (EHESS, Centre de Recherches Historiques). He is the author of numerous books, including Les savoirs perdus de l’économie. Contribution à l’équilibre du vivant (Gallimard 2023).

On Thursday 30 January 2025,  the World Inequality Lab invited George Monbiot to present and discuss his latest book The Invisible Doctrine: The SeEqualitcret History of Neoliberalism (& How it Came to Control Your Life), with Thomas Piketty, at Paris School of Economics.

 

BOOK SUMMARY

Neoliberalism. Do you know what it is? We live under an ideology that preys on every aspect of our lives: our education and our jobs; our healthcare and our leisure; our relationships and our mental wellbeing; the planet we inhabit – the very air we breathe. So pervasive has it become that, for most people, it has no name. It seems unavoidable, like a natural law.
But trace it back to its roots, and we discover that it is neither inevitable nor immutable. It was conceived, propagated, and then concealed by the powerful few. Our task is to bring it into the light—and to build a new system that is worth fighting for.

George Monbiot a British journalist, author, and environmental and political activist.

Peter Hutchison is a critically acclaimed filmmaker, NY Times bestselling author, educator and activist.

On the occasion of the release of Benjamin Lemoine’s new book, Chasseurs d’États, Les fonds vautours et la loi de New York à l’assaut de la souveraineté, the World Inequality Lab organized an online event as part of the “Equality Debates” series, on Thursday, December 5, 2024, at 12:30 p.m. The event was held in French.

Programme

• 12h30-13h00 : Présentation de Benjamin Lemoine
• 13h00-13h10 : Réactions de Thomas Piketty et Lucas Chancel, co-directeurs du WIL
• 13h10-13h30 : Questions-Réponses avec le public

 

Résumé

Chasseurs d’Etats est le fruit d’une enquête exceptionnelle sur les professionnels de la poursuite de la souveraineté – juges, avocats, enquêteurs et chasseurs d’actifs, mais aussi hauts fonctionnaires –, dont le foyer d’action est situé dans les tribunaux de New York. L’auteur raconte comment il est devenu possible d’engager des procès contre les États qui, émancipés du joug colonial, nationalisaient leur appareil productif et expropriaient les investisseurs états-uniens. La diplomatie économique des États-Unis, main dans la main avec les marchés de capitaux, a veillé à défaire les alternatives promues par les pays du Sud global et à construire le droit de New York comme l’étalon mondial des deals et litiges financiers.

Benjamin Lemoine est sociologue, chercheur au CNRS et au centre Maurice Halbwachs (École normale supérieure de Paris). Sa thèse a été primée par l’Association française de science politique. Il a obtenu en 2018 la médaille de bronze du CNRS. Il a publié L’ordre de la dette (2016, 2022) et La démocratie disciplinée par la dette (2022) aux éditions La Découverte.

On Tuesday 17 September 2024, Mordecai Kurz will give a lecture at Paris School of Economics on the relationship between inequality and technological change. This event is co-hosted by the Stone Center, the World Inequality Lab, and the EU Tax Observatory.

PROGRAMME

• 14:00 Welcome by Gabriel Zucman, Director of PSE Stone Center and EU Tax Observatory
• 14:00-14:40 – Lecture by Mordecai Kurz
• 14:40-14:50 – Comment by Thomas Piketty, Co-director of World Inequality Lab
• 14:50-15:00 – Q&A with the audience

 

OVERVIEW

The lecture will be based on Mordecai Kurz’s latest book The Market Power of Technology: Understanding the Second Gilded Age (Columbia University Press, 2023), where he argues that since the 1980s, the United States has regressed to levels of economic inequality not seen since the Gilded Age of the late nineteenth century. Kurz provides a pioneering analysis that quantifies technological market power and its impacts on inequality, innovation, and economic growth. The book also offers detailed proposals to address these inequalities, including restricting corporate mergers and acquisitions, reforming patent law, balancing power in the labor market, increasing taxation, promoting upward mobility, and stabilizing the middle class.

 

ABOUT THE AUTHOR

Mordecai Kurz is Professor Emeritus of Economics at Stanford University. His previous books include Public Investment, the Rate of Return, and Optimal Fiscal Policy (with Kenneth J. Arrow, 1970) and Endogenous Economic Fluctuations: Studies in the Theory of Rational Beliefs (1997), and he has published widely across many fields of economic theory.
