Lilia Costabile refers to Von Mises' view that new money is injected = into the economy at particular points. It is, thus, not neutral in the = sense that all price ratios between goods remain constant. New money is = not distributed from Milton Friedman's helicopter. This is not an = Austrian invention. The idea of neutrality can be found in Hume, the = idea that new money is injected at particular points dates from the same = period: Cantillon gave a detailed exposition of the process, explaining = how it would influence interest rates (Cantillon 1964 pp. 212-23). The idea may date from the 18th century, the term 'neutral money' seems = to have been coined only in 1919, by the German economist L. von = Bortkiewicz (Koopmans 1933 p. 228, nt. 1). Wicksell used the term ' = neutral rate of interest', not yet 'neutral money'. It may be noted that even if money is neutral (in a comparative-statics = analysis, or in a proximate way), it need not be super-neutral. = Super-neutrality means that changes in the rate of money growth, and = thus changes in the rate of inflation, have no real effects. This is = hardly possible if inflation has an impact on the composition of = economic agents' portfolios. Hans Visser Cantillon, R. (1964), Essai sur la Nature du Commerce en G=E9n=E9ral, = ed. by H.
