The Keynesian Root of the Tobin tax

Abstract

This paper is an attempt to evaluate the strength of the link between the Tobin tax and the so-called Keynes tax, i.e. a tax on security transactions suggested by Keynes in Chapter 12 of the General Theory. Starting from a literal comparison of the two projects, this work analyses the possibility of a common methodological background. It supports the idea that the two measures share similar fundamental targets, despite displaying technical diversity.Tobin tax, Keynes tax, security transaction taxes
