This book provides the non-Italian scholar with an extensive picture of the development of Italian economics from the Sixteenth century to the present. The thread of the narrative is the dialectics between economic theory and political action where the former attempts to enlighten the latter but at the same time receives from politics the main stimulus to enlarge its field of reflection. This is particularly clear during the Enlightenment. Inside this book insists on stressing that Galiani Verri and Beccaria were economists quite sensitive to practical issues but who also were willing to attain generally valid conclusions. In this sense pure economics was never performed in Italy. Even Pareto used economics (and sociology) in order to interpret and possibly steer the course of political action. Within this book it illustrates the Restoration period (1815-48). There was a slowdown of the economists' engagement due to an adverse political situation that prompted the economists to prefer less dangerous subjects such as the relationship between economics morals and law (the main interpreter of this attitude was Romagnosi). After 1848 however in parallel with the Risorgimento cultural climate a new vision of the economists' task was eventually manifested. Between economics and political Liberalism a sort of alliance was established whose prophet was F. Ferrara. While the Historical school of economics of German origin played a minor role Pure Economics (1890-1940 approx. ) had a considerable success as regards both economic equilibrium and the theory of public finance. Consequently the introduction of Keynes's ideas was rather troubled. Instead Hayek had an immediate success. This book concludes with a chapter devoted to the intense relationships between economic theories economic programmes and political action after 1945.
