I am full professor of Economics at the Department of Economics of Roma Tre University, Rome, where I coordinate the Laurea Magistrale (Master) in Scienze Economiche. Since 1995 I am member of the Board of the Centro Ricerche e Documentazione “Piero Sraffa”, and chair the Centro since 2011. From 2007 to 2011 I have been member of the Board of Directors of the Italian Association for the History of Political Economy. I am currently member of the Presidency Council of the Italian Economic Association. My research activity is mainly addressed to the modern reappraisal of the classical theory of value and distribution, to the critique of neoclassical theories and the full extension to the long run of the Keynesian approach to the levels of activity, to capital accumulation and to the role of economic policies.
