Tribute to Domenico Mario Nuti

This article is a tribute to the late D.M.Nuti who died at the end of 2020. It details his contributions to economic theory, economic policy, the analysis of actually existing socialism, transition economics and economic systems. It also draws attention to his role as a teacher and manager of research. He linked economists in Rome, Florence, Warsaw, Budapest, London and Cambridge. Influenced by Kalecki and the Cambridge Keynesians, he devoted his life to the study of variants of socialism and ended up advocating an updated version of social democracy. This would replace the perverted social democracy of Blair and Schroder.
