Celso Mancini

Mancini's principal work is De Juribus principatum, Libri novem (1596). The fifth book contains economic and financial matter of considerable merit. Mancini displays sound ideas on exchange and monetary economics. He distinguishes between the two duties of the state in reference to money, the care required for its maintenance, and the determination of its value, which both must correspond to the relations of the market. Mancini maintains the exclusive right of a prince to coin money, but he denies his right to debase it. Agreeing in this with other political writers of his day, Mancini regards it as the duty of a prince to maintain abundance in his dominions, exercising a paternal influence over them. The most important part of the fifth book is on finance, especially taxation. He enumerates the different taxes adopted in his day and proposes a rational classification of them, establishing the fundamental rules of finance, as the relation between taxes and the amount of public expenditure, and the proportion they should bear to the wealth of the citizens. Mancini's arguments throw considerable light on the subject of taxes, and indicate the first outlines of a doctrine which was developed much later.
