Italy is well known for its prominent economists, as well as for the typical public profile they have constantly revealed. But, when facing an illiberal and totalitarian regime, how closely did Italian economists collaborate with government in shaping its economic and political institutions, or work independently? This edited book completes a gap in the history of Italian economic thought by providing a complete work on the crucial link between economics and the Fascist regime, covering the history of political economy in Italy during the so-called “Ventennio” (1922-1943) with an institutional perspective. The approach is threefold: analysis of the academic and extra-academic scene, where economic science was elaborated and taught, the connection between economics, society and politics, and, dissemination of scientific debate. Special attention is given to the bias caused by the Fascist regime to economic debate and careers. This Volume I deals with the economics profession under Fascism, in particular in light of the political and institutional changes that the regime introduced, the restructuring of higher education, the restriction of freedom in teaching and of the press, and with respect to promoting its own strategies of political and ideological propaganda. Volume II (available separately) considers the public side of the economics profession, the “fascistisation” of culture and institutions, banishment and emigration of opponents, and post-WW2 purge of Fascist economists.
