 Pantaleoni was a major contributor to the Italian school of economics known as 'La Scienza delle Finanze'.His book "Teoria della Traslazione dei Tributi" (theory of tax shifting) is a pioneering study of tax incidence.According to Nobel prize winner James M. Buchanan, Pantaleoni and his followers (such as Antonio De Viti De Marco and Vilfredo Pareto) can be considered the intellectual forefathers of the modern public choice theory.
