Marx in the Matrix. L'algebra del 'lavoro vivo'

This paper provides a general overview on the recent interpretations of Marx’s analysis of value, money and income distribution. The paper is organized as follows. Section 1 introduces the original Marxian formulation of labour theory of value, as it is outlined in the first volume of Capital. Section 2 reproposes the ‘transformation of values into production prices’, as it is developed in the third volume. Section 3 discusses the still open issues around Marx’s trans-formation procedure. Sections 4 and 5 provide an outline on the so called ‘Single-System La-bour Theory of Value’ (SS-LTV), autonomously elaborated by Foley and Duménil since the first half of 1980s. Such an innovative approach represents a macroeconomic monetary interpreta-tion of Marx’s analysis, founded on the rediscovery of the ‘living labour’ concept. Finally, sec-tion 6 leaves behind the long-run analysis implied in the SS-LTV, in order to consider the effects of a change in the general price level (disregarding wage-earners expectations) on surplus rate.
