Jon Elster
He is also a notable proponent of analytical Marxism, and a critic of neoclassical economics and public choice theory, largely on behavioral and psychological grounds.He earned his PhD in 1972 from the École Normale Superieure in Paris with a dissertation on Karl Marx under the direction of Raymond Aron."The breadth and depth of his writings are striking in a time of high specialisation; he is read and discussed by political scientists, legal scholars, economists and philosophers.His work is difficult to summarise in a slogan, but ... it is generally informed by a broad and deep acquaintance with relevant literature in economics, political science, history, philosophy, and psychology."[10] His magisterial 500-page book Explaining Social Behavior includes something of a recantation: I now believe that rational-choice theory has less explanatory power than I used to think.[12] A more recent book, Le désintéressement (part of a two-volume Traité critique de l’homme économique), explores the ramifications of these insights for the possibility of disinterested action.
