This essay examines the contributions of Italian economist Pasquale Jannaccone to the Turin daily newspaper “La Nuova Stampa” during the Italian post-World War II reconstruction. It is argued that the major element of interest in Jannaccone's work as opinion maker lies in the educational style of most of his articles, which suggests a distinctive awareness that the level of sophistication reached by the economics profession is likely to undermine public communication. In addition to a brief survey of Jannaccone’s scientific biography, two other topics are singled out and examined: his intellectual support to the monetary policy of Luigi Einaudi during the latter’s political engagement, and his defense of the principles of economic and political liberalism in an intellectual context particularly hostile to those ideas.
