Serge-Christophe Kolm is Professor of Economics at the Ecole des Hautes Etudes en Sciences Sociales, Paris.

Review of the hardback: 'Over the last forty years Serge-Christophe Kolm has produced a body of writings that show him to be one of the most creative and profound economists of our day. In his ability to go the core of the matter - whatever it is - he has few equals. In Reciprocity he offers the fullest analysis of the topic to date, by any social scientist - a true summa.' Jon Elster, Collège de France
