In 2017, two books by Fioramonti were published Wellbeing Economy: Success in a World Without Growth and The World After GDP: Economics, Politics and International Relations in the Post-Growth Era, in May and March respectively. According to the Financial Times, Fioramonti argues that GDP is "not only a distorted mirror in which to view our increasingly complex economies, but also an impediment to building better societies."
Fioramonti has co-authored and co-edited a total of ten books. Fioramonti's books include the bestselling Gross Domestic Problem: The Politics Behind the World’s Most Powerful Number and How Numbers Rule the World: The Use and Abuse of Statistics in Global Politics. According to the Hedgehog Review, Gross Domestic Problem is one three most influential books on the gross domestic product published in the 21st century.
According to Public Books, Fioramonti’s research shows that “the reliance on GDP derives from a technocratic worldview that glorifies experts, corrodes communal values, and devalues the natural world.”" For the LSE Review of Books, his research is a kind of “psychopath’s guide to bullying the world by numbers”, unmasking the pretension that “everything is ‘rational’, ‘independent’ and ‘objective’ and building fortresses of power around these intentional misrepresentations” . Fioramonti’s work has been endorsed by public intellectuals such as Vandana Shiva, Susan George, Raj Patel and Kumi Naidoo, the former executive director of the environmental organization Greenpeace. Fioramonti is also the first Jean Monnet Programme Chair in Africa and the president of the European Union Studies Association of Sub-Saharan Africa. By 2014, he also holds the UNESCO/UNU Chair in Regional Integration, Migration and Free Movement of People
He is a fellow of the Centre for Social Investment of the University of Heidelberg, of the Hertie School of Governance and of the United Nations University. His articles have appeared in The New York Times, The Guardian,Harvard Business Review, Die Presse, Das Parlament, Der Freitag, The Mail&Guardian, Foreign Policy and openDemocracy. He has a monthly column in the Business Day, South Africa’s leading financial newspaper.
He is married and has two sons.
After being nominated in January 2018 as a candidate for the Five Star Movement in the 2018 Italian general election, Fioramonti has subsequently been elected to parliament and his name has been put forward for Minister of Economic Development.
