ln the last three decades, two questions have been central for the Left. ls there a future for electoral socialism and social democracy? And, is it any longer possible to promote a significant redistribution of income in favour of labour? Political and economic events seem to suggest negative...

This report explores the development of exploitation theory in mathematical Marxian economics by reviewing the main controversies surrounding the definition of exploitation since the contribution of Okishio (1963). The report first examines the robustness and economic implications of the debates...

The purpose of this paper is to examine the critical arguments made by Burmeis- ter, Samuelson, and others, with respect to Sraffa (1960). Sraffa did not address these arguments, but they are relevant from the viewpoint of modern economic theories. In his arguments about the standard commodity,...

The purpose of this paper is to examine the critical arguments made by Burmeister, Samuelson, and others, with respect to Sraffa (1960). In his arguments about the standard commodity, Sraffa assumed that a change in income distribution has no effect on the output level and choice of techniques,...

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...

In the standard Okishio-Morishima approach, the existence of profits is proved to be equivalent to the exploitation of labour. Yet, it can also be proved that the existence of profits is equivalent to the ‘exploitation’ of any good. Labour and commodity exploitation are just different...

In this paper we review recent developments in axiomatic studies of Marxian exploitation theory. First, given the acute controversy over the formal definition of exploitation during the 1970-1990s, we review the study of the axiomatic framework, which identifies some fundamental properties -...

This paper develops a framework to analyse imperialistic international relations and the dynamics of international exploitation. A new measure of unequal exchange across borders is proposed which captures the territorial structure of imperialistic international relations: wealthy nations are net...

This paper analyses the theoretical issues related to the measurement of labour content in the context of general technologies with heterogeneous labour. A novel axiomatic framework is used in order to formulate the key properties of the notion of labour content and analyse its theoretical...
