In a recent contribution on this journal, Matsuo (2009) has provided an interesting argument to refute the Generalised Commodity Exploitation Theorem (GCET), by highlighting a potential asymmetry between labour and other commodities. In this paper, a novel characterisation of the relation...

This paper critically evaluates a recent contribution by Kliman and Freeman (2009). It is argued that none of their arguments dispel previous criticisms of the temporal single system interpretation�(TSSI). Indeed the paper confirms the suggestions of many critics that, as the missing parts of...

This paper provides a mathematical analysis of the Marxian theory of the exploitation of labour in general equilibrium models. The two main definitions of Marxian exploitation in the literature, proposed by Morishima (1974) and Roemer (1982), respectively, are analysed in the context of general...

In the standard Okishio-Morishima approach, the existence of profits is proved to be equivalent to the exploitation of labor. Yet, it can also be proved that the existence of profits is equivalent to the “exploitation†of any good. Labor and commodity exploitation are just different...

In subsistence economies with general convex technology and rational optimising agents, a new, axiomatic approach is developed, which allows an explicit analysis of the core positive and normative intuitions behind the concept of exploitation. Three main new axioms, called Labour Exploitation in...

This paper critically analyses the strongly subjectivist approach to exploitation theory recently proposed by Matsuo ([7]), in the context of general convex economies with heterogeneous agents. It is proved that the Fundamental Marxian Theorem is not preserved in his subjectivist approach,...

This paper provides an innovative axiomatic analysis of the notion of exploitation as the unequal exchange of labour, focusing on the relation between exploitation and profits. General convex economies with heterogeneous agents endowed with unequal amounts of physical and human capital are...
